[android-developers] Changing the content of an activity runtime
Hi! I created an activity by using a layout written in a XML file. I would like, in response to some events, to change the content of this activity. I would like to show a VideoView over the content. In response to some other event, I may want to go back to the first content. Would it be possible to switch the content of the activity this way without running another activity (I have another technical difficult in doing that)? I tried using setContentView(videoView), and then switching back with setContentView(T.layout.main), but it seems that, when going back to the main layout, all my buttons and text boxes are created again as they were new. Would it be possible to go back to the last state of all the controls? Thanks for any advice! -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] How to get scroll position in a GridView? getScrollY always return 0
Hi, I have a GridView in my activity, and I want to save current scroll position while user goes to another place and restore it while user comes back. I try to use GridView.getScrollY and GridView.scrollTo methods, but getScrollY method always return 0 instead of right scroll position. Am I using this method in a wrong way? Could anyone who can teach me how to retrieve the scroll position in a GridView? I searched the Internet found that someone said we can use getSelectedItemPosition and setSelection methods, but this requires user to select at least one item, how about the case that no items is selected?

User testing is all well and good, but most users won't test your app - they'll just use it. In order to test an app well, developers need to be able to test it themselves and be able to use automated unit tests.

The SQLite files will be larger than the XML and probably slower to access, on a one-off basis.

I'm not sure other applications can have access to the resources, but you still can copy the apk in any computer and unzip it to access resources. Activating the protection mode should prevent the copy, but it's far from perfect and flawless. Last point : any one can make a screen capture of their phone... In a more general way, if you give people access to an application where they can see things, then they can prevent them to extract what they see !

[android-developers] Re: How do you approach the various devices your application runs on?
Yes you are right, it is just easier for to developers to test and for most smaller developers unlikely they will ever be able to test on all devices unless they have very deep pockets. So I perhaps should add to the above list: testing on an emulator is no substitute for testing on actual device (hence my want for Remote Device Access). Especially try and get hold of at least one device of each of the various manufacturer customised versions of Android, as these are more likely to encounter problems than stock Android (and you don't have an emulator of them).

In order for IMAP to work correctly a client makes a conneciton and gets updates. If a connection to the IMAP server is left opened you will not see any new updates. Step by step on how it should work. Example will be Exchange server: Create a new connection point to your IMAP server (Exchange) port 143 (cleartext) or 993 (Secure) add username: John Doe Add Domain: *Optional with VPN Password: ** SMTP server (Exchange) How often to login and check 5 10 15 30 1hr Logout after checking email YES/NO (Ding ding ding grand prize winner option here) This is a simple fix for Google engineers to fix, they should include it in their next rev. I'm not an expert on IMAP, though I'm some what familiar with it. It's my understanding that IMAP clients are supposed to stay connected to the mail server and receive live or periodic updates as they occur on the server, where all the action is happening. What you're describing sounds a lot more like POP3, where the client does all the work and the server acts more like a dumb storage facility, just retrieving and deleting the client's requests. In any event, both the GMail and Email apps in Android seem to be working fine with IMAP for me on my G1 (1.6) and my Nexus One (2.2). When switching from WiFi to 3G or Edge, sometimes it does seem to take a few minutes for the connection to time out and get reestablished, but I haven't experienced any problems getting my mail on either phone in either app. Raymond -- You received this message because you are subscribed to the Google Groups Android Developers group.

You can retrieve the content from the entity only once. If you have

[android-developers] Re: How to override the ENTER key behaviour of the virtual keyboard in Android
Thanks, this works, it does catch the enter key.
Just for the other curious, here is how I use it now. I have created
my own super dialog class that has 2 OnKeyListener objects and an
abstract submit method:
public abstract class MyAbstractDialog extends Dialog {
/**
* OnKeyListener that puts the focus down when the ENTER key is
pressed
*/
protected View.OnKeyListener onEnterFocusDown = new
View.OnKeyListener() {
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if ((event.getAction() == KeyEvent.ACTION_DOWN)
(keyCode == KeyEvent.KEYCODE_ENTER)) {
v.requestFocus(View.FOCUS_DOWN);
return true;
}
return false;
}
};
/**
* OnKeyListener that submits the page when the ENTER key is pressed
*/
protected View.OnKeyListener onEnterSubmitView = new
View.OnKeyListener() {
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if ((event.getAction() == KeyEvent.ACTION_DOWN)
(keyCode == KeyEvent.KEYCODE_ENTER)) {
submitView(v);
return true;
}
return false;
}
};
protected abstract void submitView(View v);
}
Now in the Dialog I can use these objects to set on my fields:
// make the ENTER key on passwordField1 put the focus on the next
field
passwordField1.setOnKeyListener(onEnterFocusDown);
// make the ENTER key on passwordField2 submit the page
passwordField2.setOnKeyListener(onEnterSubmitView);

If running another activity is what you want to do, that's what you should do. What's the technical difficult you're having doing that? I tried using setContentView(videoView), and then switching back with setContentView(T.layout.main), but it seems that, when going back to the main layout, all my buttons and text boxes are created again as they were new. That's because they are. When you use setContentView, as you have seen, you're basically loading the default version of the layout. Would it be possible to go back to the last state of all the controls? Sure, but you would have to save the state yourself and restore it on switching.

I have a gallery that displays TextViews where the background of each view is the following: ?xml version=1.0 encoding=utf-8? selector xmlns:android=http://schemas.android.com/apk/res/android; item android:state_pressed=true android:drawable=@drawable/item_pressed / item android:state_selected=true android:drawable=@drawable/item_selected / item android:drawable=@drawable/item_idle / /selector This selector work just fine for the state_pressed and default (idle) states, but the selected item state is never displayed. I REALLY do not want to force the background of the selected item by changing the background of the view when the onItemSelected event is called. What is the correct state or correct way to get the TextView background to be set properly. Is the selected (center) view in the gallery not really selected? Is there some other state I should put in the selector drawable xml? Thanks, Mark. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Changing the content of an activity runtime
Would it be possible to go back to the last state of all the controls? Sure, but you would have to save the state yourself and restore it on switching. This sounds like overkill given the other options at your disposal. For some odd reasons I managed to forgot onSaveInstanceState() / onRestoreInstanceState() methods available for that purpose.

[android-developers] Storing data on the SD card in Froyo - files deleted when upgrading
I have an application which resides on the phone memory but downloads large data to the SD card on first launch (the app needs to be able to work without an internet connection most of the time) When using the recommend directory given in Froyo it seems all files on the SD card are deleted when I install a newer version of the .apk. I'd preferably like the files removed on uninstall, but not on upgrade since the files on the SD card aren't going to change between application versions, and forcing the user to re-download a large file that is independent of the application version does not seem reasonable. At the moment it seems I'm forced to use a different directory to the recommended one in order to stop Froyo deleting all the files when the application is upgraded. Am I doing something wrong, or is this how it is supposed to work (I'm guessing it is)?

[android-developers] How to use my contact list
Hi,
i want application to send an sms to one of my contacts.the problem
consists is getting the phone number,not the name.
using this code
public void onActivityResult(int reqCode, int resultCode, Intent data)
{
super.onActivityResult(reqCode, resultCode, data);
switch (reqCode) {
case (PICK_CONTACT) :
if (resultCode == Activity.RESULT_OK) {
Uri contactData = data.getData();
Cursor c = managedQuery(contactData, null, null, null,
null);
if (c.moveToFirst()) {
String number =
c.getString(c.getColumnIndexOrThrow(People.NUMBER));
String name=
c.getString(c.getColumnIndexOrThrow(People.NAME));
txtPhoneNo.setText(number++name);
}
}
it returns null for number with the correct name,so i've tried to
get the number as int and use a cast later but get strange thing:
always number 6 instead of the phone number and always with the
correct name.
how can i fix it?
Thank you for help

[android-developers] Re: Did selected tab background colors change in 2.1 ?
Quite possibly. You should import the desired drawables from the SDK/platforms folder into your own drawables folder and reference those in order to ensure a consistent look. Remember carriers also modify their own versions which means the default styles can be quite different to the ones on the emulator.

Re: [android-developers] Re: Recent Apps change in 2.2 - Brings main Activity to foreground, not the last visible one
Actually switching from recent tasks will *never* reset the task; relaunching from launcher will reset after the time as indicated. (This is actually controlled by an intent flag, which launcher sets, and recent tasks does not.) Recent tasks should definitely not be resetting tasks. If it appears to be behaving that way, be sure your activities are actually all in the same task. You can look at the activity stack with adb shell dumpsys activity.

[android-developers] Re: How do I set the selected state of an item in a gallery (the correct way)
Not setting anything interesting that I'm aware of.
My getView in my adapter looks like:
public View getView(int position, View convertView, ViewGroup parent)
{
ImageView i;
if (convertView == null) {
i = (ImageView) View.inflate(mContext, R.layout.gallery_item,
null);
}
else {
i = (ImageView) convertView;
}
i.setImageDrawable(R.drawable.image);
// some other stuff
return i;
}
And in the gallery_item layout XML file there is just an ImageView
with the selector in my earlier post as the background.

Re: [android-developers] Re: How to update pre-installed apps
Current states: As of 1.6 Market allows installing updates to apps that already exist pre-installed on the system image. Currently however it does not know about these apps until the user explicitly installs an update, so for the initial case where the app only exists pre-installed it will not be listed as downloaded nor will the user be told about updates. In the future I know the market team is working on being able to discover these pre-installed apps and prompt the user when there are updates, but I don't know when that will appear. (When it does, though, I think it should eventually be available across all devices, since as of 1.6 Market can also self-update itself.)

Re: [android-developers] Re: Problem: Long running AsyncTask with reference to Activity
Er no for this scenario a weak reference is appropriate. You want the reference to remain valid only as long as someone else as a reference on the activity. With a weak reference, the reference will be cleared on the next GC after all other references on the activity are gone. With a soft reference, it can continue to hold the reference for some arbitrary time after that.

freeMemory() is only really accurate immediately after a GC cycle.

For this I think to obtain the size of the file and compare it with the free memory Runtime.getRuntime().getFreeMemory()). It works well but I have a new problem. The application show an error message with some images because they are so big and the application dont't detect the problem. I research in other posts and the problem is that the file size is different from the size of the image in memory. To get the size of the image in memory I use the product getHeight () * getRowBytes () of the Bitmap class, but with some images not previously had problems, I get very large sizes, so often I get the message erroneously. Does anyone know how could solve this problem? Thank you very much in advance. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Recent Apps change in 2.2 - Brings main Activity to foreground, not the last visible one
Ahh I think I've got it, my main activity has launchMode=singleTask which seems to cause all other activities above it in the stack to be destroyed. A post on StackOverflow seems to suggest setting FLAG_ACTIVITY_CLEAR_TOP|FLAG_ACTIVITY_SINGLE_TOP every time I use an intent to my main activity, so I'll try that. It would be nice if the effect of singleTask on the Recent apps function was made clear in the docs for android:launchMode. I think this will be important to people. Your own messaging app seems to do it (am unable to use recent apps to return to the message I was last looking at) and so does the Dialer (can't use recent apps to get back to my call log) and from a user perspective it makes it seem like the recent apps function is broken. Maybe I'm just picky. Alternatively my carrier possibly could have borked something in their 2.2 firmware update (I'll fire up an emulator or dig out another device in a bit and look at that) For me anyway, the following is replicable every time on my Nexus One running 2.2: 1) Reboot 2) Open calculator 3) Press back to exit calculator 4) Open messaging app 5) View any message 6) Press and hold home and select calculator to switch to that 7) Press and hold home and select messaging to switch that 8) End up looking at my list of messages, not the message I was viewing in step 5. And it doesn't happen on my Hero running 1.5 (the closest one I had lying around), but that is running Sense so who knows what HTC did with that.

Maybe my above post could have been a little clearer for anyone who comes back to look at this later: 1) The StackOverflow post http://stackoverflow.com/questions/2417468/android-bug-in-launchmodesingletask-activity-stack-not-preserved suggests using the FLAG_ACTIVITY_CLEAR_TOP|FLAG_ACTIVITY_SINGLE_TOP flags every-time you make an Intent to the activity you would like to work as a 'singleTask' and NOT using the launchMode=singleTask attribute in your manifest 2) The behaviour that is replicable on my N1, and not on my Hero, was tested using only the Calculator and Messaging apps (and HTC have changed theirs so this is probably expected) On Jul 24, 9:30 pm, Joseph Earl joseph.w.e...@gmail.com wrote: Ahh I think I've got it, my main activity has launchMode=singleTask which seems to cause all other activities above it in the stack to be destroyed.

[android-developers] Re: How to update pre-installed apps
Well I don't think pre-installed apps are the best way to get apps on the phone. Very often, users simply don't keep those pre-installed apps or they don't want to use them at least but normally those apps are hard, sometimes impossible, to remove without taking big changes in the system itself. And most of the times, the apps are already outdated when they're chipped so every new device has to update itself immediately after first boot. That's to much Windows like where you install Windows for 40 Min (Max. for me) and you're doing updates for at least 3 hours. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: J2ME
I wonder about the reverse question: if I have an Android app, is there an easy way to get it running on J2ME? (I don't feel J2ME is worth the effort of rewriting, put it that way!). Even a tool that only converted code _not_using_Android_libraries_ would be handy, but all my logic is full of Java1.5 generics, not to mention enums and so on - and whilst tools like declawer will remove some of this, it's far from a hands-off process (i.e. much fiddling to get it to compile IME!)... --Alan On Jul 23, 3:28 pm, michal.g...@gmail.com michal.g...@gmail.com wrote: You can use a service of J2ME to Android conversion by UpOnTek.

[android-developers] use of fadeScrollbars
I am using android:fadeScrollbars=true to show the scrollbar only while scrolling. Works great. The only issue I seem to be having is that the view still allocates the space on the right side to display the scrollbar when I do scroll. I really wish this worked like iPhone where the scrollbar appeared over the top of the rest of the view and still allowed the view to use all available space when not actually scrolling. -- You received this message because you are subscribed to the Google Groups Android Developers group.
