I can't find a way to obtain a reference the Window containing an arbitrary View v. I found getWindowToken, but I can't figure out how to use it? Does anyone know how? Also, does anyone know why it returns an IBinder rather than a Window?

View 2 Replies View RelatedWhat's the best way to check if the view is visible on the window?
I have a CustomView which is part of my SDK and anybody can add CustomView to their layouts. My CustomView is taking some actions when it is visible to the user periodically. So if view becomes invisible to the user then it needs to stop the timer and when it becomes visible again it should restart its course.
But unfortunately there is no certain way of checking if my CustomView becomes visible or invisible to the user. There are few things that I can check and listen to: onVisibilityChange, it is for view's visibility change, and is introduced in new API 8 version so has backward compatibility issue onWindowVisibilityChange, but my CustomView can be part of a ViewFlipper's Views so it can pose issues onDetachedFromWindows, this not as useful onWindowFocusChanged //Again my CustomView can be part of ViewFlipper's views. So if anybody has faced this kind of issues please throw some light.

I have googled it and see that it has something to do with popups and turning the screen, but there is no reference to my code.

I recently got some fade in stuff working so that my "loading" view is an ImageView that takes up the whole screen, and then I fade in the main view (a GridView in this case) over the top of it. In the activity creation, I call:

Then when the loading AsyncTask is done, I call the following:

Do I need to do anything in particular to clean up the loading_foo view to reduce the amount of memory my app is using? Any other issues with this approach?
When I apply some animation to the view, which is out of window, the animation not start immediately. And then, I scroll the screen to show the animation target view, the animation will start. I hope to the animation will start immediately when it apply.

I am using a custom title view in my application for each activity. In one of the activities, based on button clicks I need to change the custom title view. Now this works fine every time when I make a call to setFeatureInt.
But if I try to update any items in the custom title (say change the text of a button or a text view on the title), the update does not take place.
Debugging through the code shows that the text view and button instances are not null and I can also see the custom title bar. But the text on the text view or the button is not updated. Has anyone else faced this problem? How do I resolve it?

Native Start.main(Native Method) Since it comes from external beta users I dont know what they were doing when they got it. Nor do i know how to reproduce it. The stack trace does not list any of our code. Usually, this error means that there was an orientation change while a dialog was open, thereby invalidating the reference to the dialog when android recreates it. All of my activities already uses Android:configChanges="keyboardHidden|orientation" in order to prevent them from doing this. We still get the error. Has anyone else seen this before? What could be the problem?

From what I have read (http://bend-ing.blogspot.com/2008/11/properly-handle-progress-dialog-in.html) and seen in Android sources, it looks like the only possible situation to get that exception is when activity was destroyed. But as I have mentioned, I forbid activity recreation for basic events.

Is there something missing from this? Some questions have talked about having this problem when creating a dialog from onCreate, which happen because the activity isn't created yet, but this is coming from a call from a menu object, and the appContext variable seems like it is correctly populated in the debugger.

View 1 Replies View RelatedI notice that some of the base applications in Android are using this little control (View in Android terms I guess) that shows the contact picture. When you click on the picture it shows all the ways of contacting the person (phone, sms, talk, facebook). I see this little View used in the contact app, sms app, twitter for android, facebook for android etc.
Is there a library or a way of getting this working on my own application or do I need to write this from scratch?

Suppose I have a view inside TableLayout, like this:
TableLayout tableLayout;
View view = (View)tableLayout.findViewById(R.id.control);
How can I find out the view's row/column within the TableLayout?
I have a res/layout/main.xml including these elements and others:
<some.package.MyCustomView android:id="@+id/foo" (some other params) />
<TextView android:id="@+id/boring" (some other params) />
In my Activity's onCreate, I do this:
setContentView(R.layout.main);
(TextView) boring = findViewById(R.id.boring);
// ...find other elements...
MyCustomView foo = (MyCustomView) findViewById(R.id.foo);
if (foo == null) { Log.d(TAG, "epic fail"); }
The other elements are found successfully, but foo comes back null. MyCustomView has a constructor MyCustomView(Context c, AttributeSet a) and a Log.d(...) at the end of that constructor appears successfully in logcat just before the "epic fail".
findViewById() returns null for custom component in layout XML, not for other components. Why is foo null?
