[android-developers] Sqllite database join query
Hi, I already use getContentResolver().query(uri, null, null, null, null) to do a query. What if I have two databases, and I want to do one query on two databases and get one data set back?

[android-developers] GLSurfaceView transparent bg within a ViewGroup
I am able to get a GLSurfaceView to have a transparent background with mGLSurfaceView.setEGLConfigChooser(8, 8, 8, 8, 16, 0); mGLSurfaceView.getHolder().setFormat(PixelFormat.TRANSLUCENT); when I set the Activity's window background to transparent and the GLSurfaceView is the contentView of the Activity. But, let's say my GLSurfaceview is parented by a ViewGroup and I want GLSurfaceView bg to be transparent to see the Viewgroup's background - I am not able to do so with the code above. Is this a limitation or am I missing something? -George -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: drawable-hdpi not appearing in eclipse emulator
In fairness, Cameron, the docs don't actually say that android:anyDensity=false causes resources to be pulled from mdpi. The documentation for that attribute is buried in the middle of the Support for Multiple Screens page, and mostly talks about pixel density math. The confusion is compounded by the fact that, as Dianne says, the system is able to pull some resources from other directories anyway. I know it caused me some hair-pulling when I first started into serious multiple-density support; adding a sentence like the system will pull resources from the mdpi folder to the docs could be of real benefit. String On May 12, 4:40 am, Dianne Hackborn hack...@android.com wrote: Again, if you want to support multiple densities DON'T SAY YOU DON'T SUPPORT THEM. Seriously! :) The first thing to do is get rid of android:anyDensity=false so the system doesn't try to make your app think it is running in mdpi. If you still have problems after that, then we can talk about that. But until you stop telling the system to do this to you, I don't see much of a problem that it is in fact doing it.

If no such resources are available, the platform uses the default resources instead, scaling them from the baseline density (medium) to high. This is what I based my question off of. Here it says as long as I have the hdpi qualifier, it will automatically choose images from that folder for a high density screen. Is this not correct or am I missing something? I could always hard code statements to check the current screens density and preload the PNG graphics that correspond to it. I am just curious if this actually works. The upscaling of the graphics work, but not the automatic qualifier choosing.

[android-developers] Problem in the Notepadv3 tutorial code...
I've been working through the Notepad tutorial ( http://developer.android.com/guide/tutorials/notepad/index.html ) and it's been helpful. I'm aware that the second version has a bug, that is fixed in the third stage. However, the third stage (Notepadv3) still has a problem: Choose Add Note, then change the orientation. The note editing activity crashes when the orientation changes, in ActivityThread.performPauseActivity() with a NullPointerException. I'm not quite familiar enough with this platform to figure out what the issue is. I thought it had something to do with saving the row, but I thought I fixed that and it still bombs out. It's easy to reproduce the problem in the debugger. Can anyone explain what causes the crash? This might be a very good thing to get fixed; I presume a fair number of developers are going to look at that code and assume it's the way to do it...

[android-developers] HTC Incredible - images not showing up in Gallery
Hello,
I'm making an alternative camera App. As you might expect my App
involves taking pictures and saving them to the sdcard.
On most phones (and the Emulator) everything works fine, pictures
appear in the built-in Gallery App straight away.
However on the HTC incredible images only appear when the user
restarts the device. (I'm talking about an HTC Incredible phone with
an sdcard, I know some of them shipped with internal storage only, but
this is not the issue I'm talking about)
The code I'm currently trying goes like this:
public static boolean savePicture(Bitmap bitmap, int quality,
String label, Context context) {
ContentResolver resolver = context.getContentResolver();
// Save the name and description of an image in a ContentValues
map.
ContentValues values = new ContentValues(3);
values.put(MediaStore.MediaColumns.MIME_TYPE, image/jpeg);
values.put(MediaStore.MediaColumns.TITLE, label + .jpg);
// Add a new record without the bitmap
Uri uri = resolver.insert(Media.EXTERNAL_CONTENT_URI, values);
// Get a handle to the file for that record, and save the data
into
it.
try {
OutputStream outStream = resolver.openOutputStream(uri);
bitmap.compress(Bitmap.CompressFormat.JPEG, quality,
outStream);
outStream.close();
context.sendBroadcast(new
Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, uri));
} catch (Exception e) {
return false;
}
return true;
}
I've also tried MediaScannerConnection.scanFIle() with no luck.
I wonder is the problem is due to the HTC incredible being originally
designed to operate with internal storage only, maybe the Gallery App
has issues with media stored on the sdcard.

[android-developers] Displaying the ProgressDialog from the OpenGL thread.
Hi!
Does anyone have expirience with opengl-ui-opengl threading
interraction?
I'am developing a small opengl application. I'am a little bit confused
with separate opengl thread...
Currently, my application is logically separated in two parts - the
controlling one and the rendering one.
The controlling part interracts with user - accepting user input,
changing activities, dealing with files and so on.
The rendering part - just render everything it should.
Ok, so when I need to load new texture to opengl (unfortunatelly its
large and I cant reduce its size), I'd like to show a ProgerssDialog
dialog.
Trying to show it from the open gl thread brings me an exception:
Can't create handler inside thread that has not called
Looper.prepare().
Because the initiator of loading is in the ui thread (for example -
user selected a menu option), I'am opening the dialog, adding the load
Runnable to stack on Runnables that will be called in
Render.onDrawFrame and passing there a callback that will be executed
after texture is loaded.
Like this:
//ui
public class Controller extends Activity {
...
protected void loadTexture(InputStream aStream) {
final ProgressDialog dialog = new ProgressDialog(this);
dialog.setTitle(Please wait...);
dialog.setMessage(Loading texture);
dialog.show();
_renderer.loadTexture(_stream, new Runnable() {
@Override
public void run() {
dialog.dismiss();
}});
}
...
}
//gl
public class SceneRenderer implements Renderer {
@Override
public void onDrawFrame(GL10 aGL) {
this.runGLRunnables(aGL);
}
public void loadTexture(final InputStream aStream, final Runnable
aCallback) {
_glRunnablesStack.push(new GLRunnable() {
@Override
public void run(GL10 aGL) {
SceneRenderer.this.doLoadTexture(aStream);
aCallback.run();
};});
}
}
So the question is: Is there any way to show ProgressDialog from the
opengl thread?
I need exactly the ProgressDialog. There is a way to show some
picture, previously loaded, like a splashscreen using opengl renderer,
but I'd like to avoid it.
Thanks!

[android-developers] accessing sqlite db
hi,
Im starting with android and have few questions about database access.
1. Every tutorial I ve read (ie Notepad) that uses sqlite creates and
opens connection via SQLiteOpenHelper in onCreate callback. but I
really have never seen that the connection is closed (androids throws
exceptions that there is a leak as connection is never closed). So I
assume that onSaveInstanceState is the best bet to close as onCreate
opens the connection. but maybe it should be sooner - something like
onResume (for open) and onPause (for close). or maybe those tutorials
are too trivial and I should create another layer for accessing data
in services, so that data could be shared between activities and
wouldn't suffer from activity life cycle.
the only thing is that the exception is thrown after a while - not
immediately after destroying activity

[android-developers] Re: Using same sqlite database from multiple Activities and Services
I'm not sure if you guys have looked into reference counting, but that
sounds like a possible solution to me. If you use a static reference
count in your database helper object, your close method can only close
the connection if there's just one reference left. I'm actually still
working through this issue myself, but that sounds like it could fix
some people's problems.

I have been trying to find a discussion on the best way to handle a

It seems that if each Activity has:

{
SQLiteDatabase db = SQLiteDatabase.openDatabase(...)
...
}
void onDestroy()
{
db.close();
...
}
this would be wasteful, assuming there would be N SQLiteDatabase
objects with N activities that needed access to the same db.
One could go about making a singleton, but who would be responsible
for closing thedatabasewhen the application terminates?
Would it be best to extend the android.app.Application class and hook
into the onTerminate() to close thedatabase?
Taking a look at NotePadv3Solution, I can't find where it closes the
database- and that is a pretty straightforward example.

What I did (which may not be the best solution is to call the
db.close() in onPause() method and call the db.open() in any
onResume() method of all activities.
Be aware that during the activity creation both onCreate() and
onResume() methods are called, so you need to check the db is not
opened yet.
Hope this helps,
Federico

[android-developers] Is SPP supported by Android BT API?
Hello, I'm a little bit confused about supporting SPP by Android API(from level 5). As I understand it wasn't supported in versions before API level 5 what we can read in discussion below.(First Nick's post) http://groups.google.com/group/android-developers/browse_thread/thread/f6895002803f6a5b/b7278a83a3b4928d?lnk=gstq=bluetooth+spp#b7278a83a3b4928d But it was in October and after that we have APi from 5 to 7 now released. And my question is do all these API's support SPP? As I read in other discussions some phones makes more difficulties than others. Which mobile phone you can recommend? In API reference we can read that: The most common type of Bluetooth socket is RFCOMM, which is the type supported by the Android APIs. RFCOMM is a connection-oriented, streaming transport over Bluetooth. It is also known as the Serial Port Profile (SPP). As I know RFCOMM is not the same as SPP. What is the difference between RFCOMM and SPP and it's configuration in Android API?

[android-developers] audio player writing to AudioTrack
I've implemented an audio player that does decoding and decryption, so writes to an AudioTrack object. The decoding and decryption is done in native code. On the more powerful phones everything works fine, but on the lower-power (e.g. HTC my touch) phones when I switch activities the CPU becomes completely pegged and the audio becomes crackly. The first change was to keep the decoding and writing to the AudioTrack entirely in native code, which seemed to help a little. But, the audio still was bad, so, I re-factored out the portion of the audio player class that is responsible for doing the actual playback -- the rest of this class provides access to the meta data in the file, which is in proprietary format -- and am running this as a remote service. The runs fine on the more powerful phones, but *only* runs fine on the lower-power phones if I do the following: - start up the application - switch to another application - switch back to the application - start the audio player Could anyone guess what switching to the other application does? The CPU usage graphs look the same for both the app and player processes when doing this. Thanks.

[android-developers] Marquee in various TextView at the same time?
Hi, I have a dinamic layout wich has one to six TextViews. All the TextViews are created in the Activity (programatically) and all are created equally. I want to marquee the text in the TextViews, but I don't know how to do it. Apparently, the TextView needs to be focused for the marquee works fine, but how i focus six TextViews at the same time? I think that's not possible, so, is there any workaround? Is it possible to get the marquee working without having the focus? This is the code of the TextViews: //TextView TextView tvTitulo = new TextView(this); tvTitulo.setText(Some loong text); tvTitulo.setTypeface(null, Typeface.BOLD); //Marquee tvTitulo.setSingleLine(); tvTitulo.setEllipsize(TruncateAt.MARQUEE); tvTitulo.setHorizontallyScrolling(true); tvTitulo.setFocusableInTouchMode(true); If I remove the line tvTitulo.setFocusableInTouchMode(true); the marquee is not working at all. If I don't remove the line, only one of the TextViews is getting the marquee working. Greetings -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Dynamically update preferences
Hi, we have an XML file placed in the res/xml folder containing our preferences. Is it possible at runtime to add new items to the preferences. Example: The user starts the app and the preferences consists of: America - New York - Los Angeles - Chicago Where all the cities are CheckBoxPreferences. Then the user performs some actions in the application and this triggers that two new cities are added to the preferences: America - New York - Los Angeles - Chicago - Seatlle - Washington We have tried to place the XML file with the preferences in the assets directory, but from there we can't get the preferences into Android Preferences (like we do when the file is placed in the res/xml directory).

[android-developers] Problem with startManagingCursor
Hello! I'm experiencing a problem that I fail to understand, maybe somebody can help. I'm using a MergeCursor in a ListActivity and a ResourceCursorAdapter. The MergeCursor consists of several Cursors that come from regular ContentProvider queries. After constructing the MergeCursor, I call startManagingCursor on it - I followed that pattern before without a problem. My problem is that sometimes (not all the time), going to another Activity and coming back, I receive this exception: android.database.StaleDataException: Access closed cursor at android.database.AbstractWindowedCursor.checkPosition(AbstractWindowedCursor.java: 175) at android.database.AbstractWindowedCursor.getLong(AbstractWindowedCursor.java: 99) at android.database.CursorWrapper.getLong(CursorWrapper.java:127) at android.database.MergeCursor.getLong(MergeCursor.java:142) at android.widget.CursorAdapter.getItemId(CursorAdapter.java:156) at android.widget.AdapterView.rememberSyncState(AdapterView.java: 1085) at android.widget.AdapterView $AdapterDataSetObserver.onChanged(AdapterView.java:784) at android.database.DataSetObservable.notifyChanged(DataSetObservable.java: 31) at android.widget.BaseAdapter.notifyDataSetChanged(BaseAdapter.java:50) at android.widget.CursorAdapter $MyDataSetObserver.onChanged(CursorAdapter.java:385) at android.database.DataSetObservable.notifyChanged(DataSetObservable.java: 31) at android.database.AbstractCursor.requery(AbstractCursor.java:97) at android.database.sqlite.SQLiteCursor.requery(SQLiteCursor.java: 561) at android.database.CursorWrapper.requery(CursorWrapper.java:211) at android.database.MergeCursor.requery(MergeCursor.java:247) at android.app.Activity.performRestart(Activity.java:3522) at android.app.ActivityThread.performRestartActivity(ActivityThread.java: 2967) at android.app.LocalActivityManager.moveToState(LocalActivityManager.java: 160) at android.app.LocalActivityManager.startActivity(LocalActivityManager.java: 321) (...) My understanding of it is that my managed cursor was deactivated, then going back it is requeried, but doing so a notification is sent to my adapter (DataSetObservable.notifyChanged). So the adapter then tries to access the cursor... which is in the middle of the requery, and so this exception is raised! What did I do wrong?

On May 11, 9:08 pm, Streets Of Boston flyingdutc...@gmail.com wrote:
You probably do NOT want to put the starting and stopping of the
location (GPS) providers in the onStart() and onStop().
The onStop() may not be called when your activity goes to the
background:
- It is not called because your activity remains active in the
background
- It is not called because the OS just killed your entire process.
(this would actually kill the GPS provider as well).
Instead, start and stop the GPS provider in the onResume() and
onPause().

[android-developers] does android correct gps altitude ?
Hi, i've decoded some nmea lines delivered by the location manager where i retrieved the longitude, latitude, altitude and others informations. Then i compared theses informations with those stored in a Location object that i got from a location listener. I found out that there is a difference between the location.altitude and the nmea.altitude. The difference is always about 50 m. I think android corrects the latitude but I'm not sure. Is somebody has more informations about that ? I've also retrieved the HDOP, VDOP and PDOP from the nmea lines but i don't know how to compare them with the accuracy since it is given in meters.

Re: RE : Re: [android-developers] starting an application with Android 1.5
I see now, the method i would like to use in 1.5 is setPackage not
setComponent; sorry for the misunderstanding.
I don't want to use setComponent because i don't know the classname to use
(and i don't want to hardcode it as i guess it might change as it is an
external application). And setPackage is only available since API level 4 :(
I have used your Launchalot exemples to dynamically retrieve the classname.
Here is what i did that seems to work:
String packageName = com.foo.blabla;
Intent mainApps = new Intent(Intent.ACTION_MAIN);
mainApps.addCategory(Intent.CATEGORY_LAUNCHER);
ListResolveInfo activities =
act.getPackageManager().queryIntentActivities(mainApps, 0);
IteratorResolveInfo it = activities.iterator();
while (it.hasNext()) {
ResolveInfo info = it.next();
ActivityInfo activity=info.activityInfo;
if (activity.packageName.equalsIgnoreCase(packageName )) {
Intent intent=new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
ComponentName name = new
ComponentName(activity.packageName, activity.name);
intent.setComponent(name);
act.startActivity(intent);
return true;
}
}
// handle not found case
Any shorter and faster way (and compatible with 1.5) to do it is welcome :)

Hi Mark,
Yes sorry, my mail was not clear but you got it.
I was really sure this was available from 1.6. It seems I need to have a
rest! I will try that tomorrow.
Thanks you both for the lightning fast help :)

There is no concept in Android of start an application. There is
start an activity, even start an activity that appears in the Launcher.
Ok, there is Intent.setComponent solution would be what i need ... if it
was compatible with 1
Not to mention the fact that this will not work by itself.
BTW, setComponent() most certainly works with Android 1.5, since that
method existed since API Level 1 (a.k.a., Android 1.0).
I guess i have to play with getPackageManager() but how can i use it?
Intent i=new Intent(Intent.ACTION_MAIN);
i.addCategory(Intent.CATEGORY_LAUNCHER);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
i.setComponent(name);
startActivity(i);

Hi Miguel, Thanks. do you recommend Local Androis Service or Remote Android Services design ? Thanks Luc On 23 avr, 01:30, Miguel Morales therevolti...@gmail.com wrote: Making a realtime action game will be difficult when you start to take into account network latency. Specially if you want people to play your game over a 3G or Edge connection. Your problem might be in the way you are polling for data. If you have a looping thread, it'll hog your CPU and yourFPSwill suffer. You may be able to counter this using wait() and notify() or a Looper/Handler pattern. There are several ways to solve this, however this is what I did. Decouple the network functions to use a service in a different process. When the services receives network data, we call a callback function in the the main game process. This is quite fast for me using rough measures. However, in your case a simple lock might do the trick since from my experiments, it is much faster than a queue/handler. Again, I suspect that your simply using a bad poll technique in your network thread.

If when i start displaying the game i stop the my socket protocol threads (reader, writer) the game is refreshed at 25FPSwhich is not 50FPSbut large enought to make the game playable.

[android-developers] Layout Issue: Status Bar Space Remains Empty || Status Bar Animation
(1)
I have an issue with the following code:
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
On my emulator this seems to work fine. The status bar disappears and the
empty space is filled with the content view. However on my Nexus One this
sometimes works and sometimes the empty space remains empty/black.
Any idea why this happens?
I tried to counteract this, but my naive approach wasn't fruitful:
handler.postDelayed(new Runnable() {
@Override
public void run() {
v.getRootView().invalidate();
v.getRootView().requestLayout();
v.getRootView().forceLayout();
}
}, 800);
I tried those things from above separately, synchronously and delayed.
(2)
Also I wanted to check if I can remove the status bar's animation or tap
into that with my own animation. To do that I tried to find the status bar.
But using Activity.getWindow().getDecorView() and View.getRootView() both
returned the same View, but it doesn't have the status bar as a child:
[image: Screen shot 2010-05-12 at 2.02.44 PM.png]
That's also what the status bar shows. My content starts with the NO_ID
container, but above that there is no status bar.
What's up with that? Is it hidden from ordinary apps? Could I still tap into
its animation?
Cheers,
Mariano

[android-developers] Clarification on loading local images with WebView

So I am putting it in the assets directory of the app. - The page.html that gets downloaded from my server, then has a regular img tag in it like so: img src=file:///android_asset/largeimage.png/ I know there were some issues with reading assets from the file system with different versions of the platform. But its not clear what versions this affects and how to address the problem for all versions. Can someone please clarify: A) should what I am doing above work (because its not) B) If it only works on some versions of the platform - which versions? How should this be addressed when I can't guarantee what version of the platform users are running? I am targeting version 1.6 in my app because I thought that would be a safe version to target. I am testing against version 2.0.1 Thanks, Jeff -- You received this message because you are subscribed to the Google Groups Android Developers group.

Did you guys notice anything about ProGuard actually supporting encryption? Nope. It just says obfuscator. Hence why I put 'obfuscator', had I meant encryption I would have written that.

Yes, it isn't encrypted, I have tried to decompile obfuscated byte code generated by other products before using JAD (as a test since my company was using it), and was unable to retrieve anything meaningful from it.

Re: [android-developers] Clarification on loading local images with WebView
Jeff wrote: Hello all, I apologize if this is beating a dead horse, but I have been through the documentation and groups discussions over and over, and can't seem to resolve this issue What I want to do: - I am loading a remote web page into WebView using loadUrl() - example: webView.loadUrl(http://myserver.com/page.html;); - That page has a very large image in it whose quality I do not want degraded by the OS. So I am putting it in the assets directory of the app. - The page.html that gets downloaded from my server, then has a regular img tag in it like so: img src=file:///android_asset/largeimage.png/ I know there were some issues with reading assets from the file system with different versions of the platform. But its not clear what versions this affects and how to address the problem for all versions. Can someone please clarify: A) should what I am doing above work (because its not) Since you are loading the Web page from the Internet, I imagine WebView will block local file access. This is not significantly different than regular Web browsers, last I checked. Otherwise, Javascript could rummage around the local file system, grab data, and send it hither and proverbially yon. B) If it only works on some versions of the platform - which versions? How should this be addressed when I can't guarantee what version of the platform users are running? Try creating a ContentProvider to serve the image, and see if you have better luck with a content:// URL. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy _Android Programming Tutorials_ Version 2.0 Available! -- You received this message because you are subscribed to the Google Groups Android Developers group.

Are you thinking that the HTC Incredible does NOT scan the SD-card

On May 9, 5:48 am, Martiño martino.figue...@gmail.com wrote:
Hello,
I'm making an alternative camera App. As you might expect my App
involves taking pictures and saving them to the sdcard.
On most phones (and the Emulator) everything works fine, pictures
appear in the built-in Gallery App straight away.
However on the HTC incredible images only appear when the user
restarts the device. (I'm talking about an HTC Incredible phone with
an sdcard, I know some of them shipped with internal storage only, but
this is not the issue I'm talking about)
The code I'm currently trying goes like this:
public static boolean savePicture(Bitmap bitmap, int quality,
String label, Context context) {
ContentResolver resolver = context.getContentResolver();
// Save the name and description of an image in a
ContentValues map.
ContentValues values = new ContentValues(3);
values.put(MediaStore.MediaColumns.MIME_TYPE, image/jpeg);
values.put(MediaStore.MediaColumns.TITLE, label + .jpg);
// Add a new record without the bitmap
Uri uri = resolver.insert(Media.EXTERNAL_CONTENT_URI, values);
// Get a handle to the file for that record, and save the
data into
it.
try {
OutputStream outStream =
resolver.openOutputStream(uri);
bitmap.compress(Bitmap.CompressFormat.JPEG, quality,
outStream);
outStream.close();
context.sendBroadcast(new
Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, uri));
} catch (Exception e) {
return false;
}
return true;
}
I've also tried MediaScannerConnection.scanFIle() with no luck.
I wonder is the problem is due to the HTC incredible being originally
designed to operate with internal storage only, maybe the Gallery App
has issues with media stored on the sdcard.

[android-developers] Re: ListView created programmat ically - emptyView doesn’t pop up
Yes, exactly!
I've tried everything, but nothing helped. Finally it turned out that
emptyview must be a part of contentview, for example as in ApiDemos -
List8. I've changed the way of creating PlayerList from programmatic
to View.inflating(...) , PlayerView was a part of contentView
(PlayerView and my emptyView were both inside FrameLayout), and I've
called setEmptyView(findViewWithTag(...)) later in procedure of
changing content view, and everything worked.

Re: [android-developers] Strange Error: WIN DEATH: Window{44bba600 SurfaceView paused=false}
I have seen this when I was using OpenGL VBO and didn't reset the buffer
bindings back to default.

I could run the same programing in HTC Magic and when it comes to
Nexus one, this error occurs.
Thanks in advance

[android-developers] Re: volume key pressed to ignore call
Okay, need to read the API a bit better ... AudioManager.getMode() is what I was looking for.

[android-developers] string-array max size?
Hey, I have a string-array in my resource file that has a little over 1,000 items in it. When I go to launch the activity that calls an AutoCompleteTextView the app won't load this array it simply backs out of that activity and returns to the previous activity. If I delete a bunch of items in the array it begins to work. How can I make it hold all my items? Is there a max size associated with this? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Gallery elasticity at the ends
Hi all, I use the gallery view extensively as a full screen pagination mechanism. It works really well for me without having to create a brand new control. I would like to add a little elasticity at the ends (much like the iPhone homescreen). How could I go about doing this? Any hint as to which method I would need to override/modify? Thanks in advance.
