[android-developers] No onEditorAction on Xperia Tablet
Dear All, I am testing some code on a sony xperia z2 tablet. I am having some problems with the sony software keyboard. Its not calling onEditorAction(). I don't think its a problem with my code. Since when I switch the keyboard, to for example the hackers keyboard app, my code receives onEditorAction() calls. What the sony software keyboad does is the following: When pressing enter, it just inserts the newline in the multi-line text field of my app. But it does not invoke onEditorAction(). Is there some special trick to instruct the sony xperia software keyboard to call onEditorAction()? Some hidden ime options? Or some other route like an InputChannel? Best Regards P.S.: For onKey the android doc says: Do not assume a software input method has to be key-based; .. there is no way to reliably catch soft input key presses. Is there a similar no guarantee for editor actions? -- You received this message because you are subscribed to the Google Groups Android Developers group.

Satya Komatineni schrieb:
For a UI action in the same thread:

So, no rectangle is invalid (I am assuming that is the assertion

Is it possible that the layout phase may invalidate() some of the
views? I suppose for those views that don't change their position or
size, I am assuming onDraw() won't be called.
Wondering if someone could comment on this.
Thanks a lot.

Maybe you are not dealing with GridView? But in case:
I recently wanted to refresh a GridView. And tried
first requestLayout(). Nothing happened. I then tried
invalidate(). Again nothing happened. So finally I
went for invalidateViews(), which was fine.
But this is AbsListView specific (*):
public void invalidateViews ()
Causes all the views to be rebuilt and redrawn.
And I would be more happy if I could invalidate a
single grid element separately, when I know that only
the appearance changed. But I did not yet have time
to figure this out.
Bye
P.S.:
Some source code for GridView says:
/**
* Causes all the views to be rebuilt and redrawn.
*/
public void invalidateViews() {
mDataChanged = true;
rememberSyncState();
requestLayout();
invalidate();
}
And in AdapterView:
/**
* True if the data has changed since the last layout
*/
boolean mDataChanged;

Use getSpans(), find all occurrences of your span, remove the old

It's possible that there is a more efficient alternative than this,
but I am not aware of one.
I went for a custom class:
public class MyForegroundColorSpan extends CharacterStyle
implements UpdateAppearance {
private int color;
public int getForegroundColor() {
return color;
}
public void setForegroundColor(int c) {
color = c;

public void updateDrawState(TextPaint ds) {
ds.setColor(color);

Then using the setter and calling invalidate() on
the text view works like a charm.

That's not true. Android supports basic Java Threads and there's no
reason for not to use them when appropriate. But the thing is, you can
not alter UI components outside of UI Thread. In your case it would be
updating the textual contents of TextView. See method named
runOnUiThread , it gives easy access for executing UI code from Threads.
Thanks, I guess runOnUiThread() corresponds to the
SwingUtilities invokeLater(), plus some smarts to bypass
posting if already in UiThread (*).
I guess there are situations where the smarts is not needed
and where one wants a invokeAndWait(). I built myself
AndroidUtilties which provide the later. The code reads
as follows:
public class AndroidUtilities {
public static void invokeLater(View v, Runnable r) {
if (!v.post(r))
throw new RuntimeException(looper missing);
}
public static void invokeAndWait(View v, Runnable r)
throws InterruptedException {
WaitAdapter wa = new WaitAdapter(r);
AndroidUtilities.invokeLater(v, wa);
wa.doneJob();
}
}
class WaitAdapter implements Runnable {
private Runnable job;
private volatile boolean donejob;
private final Object donelock = new Object();
WaitAdapter(Runnable j) {
job = j;
}
public void run() {
job.run();
synchronized (donelock) {
donejob = true;
donelock.notifyAll();
}
}
void doneJob() throws InterruptedException {
synchronized (donelock) {
while (!donejob)
donelock.wait();
}
}
}
The annoying thing is that one has to remember and/or
pass around a view all the time. The above code could
of course also be adapted so that it takes an activity
parameter instead of a view parameter, but still the
annoyance will be there.

Hi,
Is it possible to share data between the Android framework and an app?
I'm modifying the Android framework login component so that a variable
will be saved upon login, and then later retrieved by another app. I'm
trying to use SharedPreferences, and my code looks like this:
In com.android.internal.policy.impl.PasswordUnlockScreen.java, I have
the following code to write to the SharedPreferences.
SharedPreferences prefs = getContext().getSharedPreferences(mypref,
Context.MODE_WORLD_READABLE);
SharedPreferences.Editor editor = prefs.edit();
editor.putString(mypref, my data
editor.commit();
In my other app, I have the following code to read from it.
Context con;
String data;
try {
con = this.createPackageContext(com.android.internal.policy.impl, 0);
SharedPreferences pref = con.getSharedPreferences(mypref,
Context.MODE_PRIVATE);
data = pref.getString(mypref, 0)
} catch (NameNotFoundException e) {
data = 0;
Log.e(No data shared, e.toString());
}
When I run the code, I keep getting the NameNotFoundException, as it
claims the application package com.android.internal.policy.impl is not
found, so my data is always 0.
How can I share data between these 2 components?
Thanks.

[android-developers] Re: Cursor Blinking Management (TabHost/ActivityGroup)
Dear All, Got a little progress in the blinking issue. Made the following observation. The method: tabHost.clearAllTabs(); Does not clear the selected status of the tabs in the tab widget. As a result one can provoke multiple selected tabs: +--+--+--+--+ | Tab1 | Tab2 | Tab3 | Tab4 | +--+--+--+--+ Tab2 selected and Tab3 selected I found the following work-around which mittigates a little bit the problem. Insert a tabHost.setCurrentTab(0) in front of the tabHost.clearAllTabs(): tabHost.setCurrentTab(0); tabHost.clearAllTabs(); tabHost.addSpec(spec1) .. tabHost.addSpec(specn) This works since after tabHost.clearAllTabs() the selected index is set to -1. And then tabHost.addHost(), when it sees selected index = -1, will set the selected index to 0. So that after the first tabHost.addHost() the invariant that the selected index corresponds with the select status of the tabs is guaranteed. But still the blinking is not yet perfect. I now got most of the time the first tab not blinking, but the other tabs will now blink. Sometimes even more tabs than only the first tabs don't blink. But the situation is already better. And since I do visualize the tab selection status now, with the above fix, this visualization is now always consistent, no more multiple selected tabs seen. But still working on it...

Since my application is a tab host, if I switch to another tab, this is exactly what happens underneath, the tab that comes to front also receives a request focus. You can lookup the source code of the tab host. The tab host will first try to focus inside the tab widget, but if there are no focusable elements it will next focus inside the fragment. The fact is that some of the tabs that receives the focus nevertheless don't switch on the cursor blinking whereas some switch on the cursor blinking. Basically those tabs that where first removed via clearAllTabs() and then re-added via addTab() lose the blinking. Tabs that were freshly added don't lose the blinking. The clearAllTabs() / addTab() thing is a workaround to the fact that the tab host does not provide removeTab() or insertTab().

[android-developers] Workaround NullPointerException TabWidget?
Dear All,
Is there some workaround for a null pointer exception
in TabWidget. It basically happens in the following code:
tabHost.clearAllTabs();
tabHost.addTab(spec);
The clearAllTabs sets the mSelectedTab to -1. The problem is
some sloppy code in the Android 2.3.7 version of TabWidget:
337public void setCurrentTab(int index) {
[...]
342getChildTabViewAt(mSelectedTab).setSelected(false);
The crash is in 342 since getChildTabViewAt returns null
when mSelectedTab == -1.
This was fixed in the Android 4.0.3 version or maybe before
of TabWidget:
386public void [More ...] setCurrentTab(int index) {
[...]
391if (mSelectedTab != -1) {
392getChildTabViewAt(mSelectedTab).setSelected(false);
393}
How would one go about to workaround the problem in Android 2.3.7?

[android-developers] Re: Workaround NullPointerException TabWidget?
Hi,
Just did this. Actually the problem was not a mSelectedTab = -1,
but rather a mSelectedTab = 1 and a getChildCount = 1. This
problem I do not seen on Android 4.0.3.
The workaround code that works for me is:
public class TabWidgetFix extends TabWidget {
private final View dummy;
/**
* pCreate a tab widget fix./p
* @param c The context.
*/
public TabWidgetFix(Context c) {
super(c);
dummy = new View(c);
}
/**
* pRetrieve a child tab view./p
*
* @param i The index.
* @return The child tab view.
*/
public View getChildAt(int i) {
if (i 0 || i = getChildCount())
return dummy;
return super.getChildAt(i);
}
}
But there remains one minor problem. I use the
clearAllTabs() based code:
tabHost.clearAllTabs();
tabHost.addTab(spec);
Since there is no removeTab API available. But now
some of the sub activities in the activity loose their
blinking cursor.

[android-developers] Cursor Blinking Management (TabHost/ActivityGroup)
Dear All, To manage tabs I use the following code: tabHost.clearAllTabs(); tabHost.addTab(spec); /* for multiple specs */ I can add and remove tabs this way. Since the specs contain a tag, sub activities are refound. When I remove a tab, I also call: getLocalActivityManager().destroyActivity(tag,true); Now there is a slight problem. My tabs are mostly text editors. Now for example when I add a tab, then cursor blinking works on the new tab. But for the existing tabs, which have been cleared and then re-added, the cursor blinking stops. What could be done to correctly restore cursor blinking?

[android-developers] Re: Cursor Blinking Management (TabHost/ActivityGroup)
What do you mean by manually set the focus? For the new tab I call setCurrentTab() when I add it. The old tabs are focused via the TabHost/TabWidget interaction, which I do not intercept. Both the old and the new tab receive the focus. But the cursor is not blinking for the old tab. You can type in something, the cursor moves but does not blink anymore, so if you type abc, you will see: abc| The vertical is the cursor, but it does not blink anymore. By chance it can also happen that the cursor is not visible at all. If the old tab would not receive focus, you could not type abc in the first place.

[android-developers] Are you kidding me? EMS = LineHeight
Dear All,
I was using setEms() to set the width of a text
field. But the text field looks much to wide for
me. So I went into the source code and looked
what is really happening there, and it seems
that Ems is equated with LineHeight:
android.widget.TextView:
if (mMaxWidthMode == EMS) {
width = Math.min(width, mMaxWidth * getLineHeight());
} else {
width = Math.min(width, mMaxWidth);
}
How would one go about, and use a more
reliable measure. For example to display a
text field with a fixed count of digits?

[android-developers] Customizing Select-All / Cut after InputFilter
Dear All
I have an EditText with an InputFilter. The InputFilter
restricts the editable area of the edit text to everything
above inputoffset:
public CharSequence filter(CharSequence source, int start, int end,
Spanned dest, int dstart, int dend) {
if (dstart = inputoffset) {
return null;
} else {
return dest.subSequence(dstart, dend);
}
}
The above works fine, I can indeed not edit anything
above inputoffset. But the system edit action bar
still thinks the full edit text is editable. Namely:
- Cut Action is enabled, even if selection is above input offset.
- Select All Action selects full text, in the present case
it is desired that only the range inputoffset - text.length
is selected.
How can I programmatically customize the select all action
and the cut action?

Theoretically:
android:sharedUserId
The name of a Linux user ID that will be shared with other
applications. By default, Android assigns each application its own
unique user ID. However, if this attribute is set to the same value for
two or more applications, they will all share the same ID — provided
that they are also signed by the same certificate. Application with the
same user ID can access each other's data and, if desired, run in the
same process.
http://developer.android.com/guide/topics/manifest/manifest-element.html#uid
android:process
The name of a process where all components of the application
should run. Each component can override this default by setting its own
process attribute.
By default, Android creates a process for an application when the
first of its components needs to run. All components then run in that
process. The name of the default process matches the package name set by
the manifest element.
By setting this attribute to a process name that's shared with
another application, you can arrange for components of both applications
to run in the same process — but only if the two applications also share
a user ID and be signed with the same certificate.
If the name assigned to this attribute begins with a colon (':'), a
new process, private to the application, is created when it's needed. If
the process name begins with a lowercase character, a global process of
that name is created. A global process can be shared with other
applications, reducing resource usage.

There is: void onLowMemory() This is called when the overall system is running low on memory, and would like actively running process to try to tighten their belt. http://developer.android.com/reference/android/app/Application.html And: public longthreshold The threshold of availMem at which we consider memory to be low and start killing background services and other non-extraneous processes. http://developer.android.com/reference/android/app/ActivityManager.MemoryInfo.html There seem also to be more APIs since Level 14, for example onTrimMemory in Application, but I will try level 10 for the moment. I also found SystemClock useful, but I am still missing an API that would give me some statistics about how much time spent in GC. Best Regards Jan Burse schrieb: Mark Murphy schrieb: You are missing the point. If I am understanding the documentation for MemoryPoolMXBean, there cannot be some other lib. I believe that you will be needing to remove the ties to javax.management, not replace them. Since I only need the memory threshold functionality I could easily implement the functionality in Android by myself by polling Runtime.freeMemory() in a thread. The later is available in Android. But it would be more handy if there is some existing lib or even an API in Android that I did not yet see.

If this is third-party code you are attempting to use, it is unlikely that it is designed with Android in mind and likely will need to be rewritten. I was originally using JDK 1.7 from Oracle and openjdk 1.7 on various platforms (Windows, Mac, Linux). Both provide javax.management.* and java.lang.management.* and the application loaded fine. I am now trying to port the application to android, but the android version doesn't load, since the classes are missing. I can freely change the application for android, and use some other lib if its available. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Honeycomb (Android 3.2) emulator slow
Dear All, Is it me or is it the system? I just installed the Android SDK and were running a virtual device for Android 3.2. I am using a Windows 7 box. It seems to me that the emulator has some problems in building the screen in time. I didn't have the feeling of smooth interaction. Android 2.3 did work fine. But Android 3.2 looks not smooth to me. I read something about OpenGL on the net, and one of the sample codes, a textured triangle said 100ms per frame. Which is pretty slow. Is this a known problem? What can be done?

Mark Murphy schrieb: Set the Device RAM size to 1024. Yes, why not, would it help? Replace the home screen with something faster. What do you mean by that? I tried already window scale 96dpi Which makes the window smaller. But I have the feeling the whole graphics is broken, font look small and ugly then. I have already seen small fonts that weren't ugly. And buy a Core i7 with Turbo Boost to 3.4GHz. No, doesn't help. I have already 4 cores, and one core goes up with the emulator. The emulator does not use multiple cores. Or, buy a Honeycomb tablet Were just looking at the prices. They still feel a little bit high.

It also works ok here for android 2.3. The issue is mainly it does not scale to android 3.2. -- You received this message because you are subscribed to the Google Groups Android Developers group.
