I have a listview managed by an adapter that is extending BaseAdapter.
In the getview function im using the convertView to set up a OnClickListener. This OnClickListener work well when I am touching the screen but if I use the trackball of the HTC Desire, I see the row flashing on the screen, but the OnClickListener is not called...
I've read the android dev guide : http://developer.android.com/guide/topics/ui/ui-events.html
and its say that I should receive a onClick event from the trackball...
Im putting here my getview code in case someone see anything strange.

Is any way to build and fire an event (e.g. on click event) in android applications programmatically.
I have an Activity (lets call it A) with multiple views (5 ImageView for example). And a normal Java class (lets call it B) which is used by my Activity. here is an instance of B in my Activity. If user click on a View (Image View) the view OnClickListener calls a method in B In B, if operation is successful, it will call back a method in activity again. in activity method, It will change image or state for clicked ImageView.
I the other hand: click on view (x) in Activity -------> B.doSomething() --------> A.bIsDone() -----> change image for view (x) with normal execution, its working and there is no problem. the problem is that I want to simulate this process to be automatic, my code looks like this:
CODE:.............
The issue is that, it won't render anything, until the end of the loop.
I tried to put the loop in another Thread, but its throwing exception: android.view.ViewRoot$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.
What can i do for this issue? i was think generate an click event on view (by code), to see it can help or not.

In fact, only the touch_down event will fire. Basically, I'm trying to implement a drag feature in my app so I need the touch_move event. I have a method that writes out the touch events to the LogCat in Eclipse but the touch_down is the only event that shows up. not even touch_up shows up. I have this problem when I debug on the device or in the avd.
This isn't really a code question. But has anyone had an issue getting different touch events to fire? If so, how did you resolve them? I'm using the latest Android SDK and Eclipse version. I'm using a simple ImageView.

I'm trying to implement pinch-zoom in an app I'm making and am having issues with the onTouch event. It appears that the pointer up & down actions do not fire immediately, like you won't get a pointer up or down until an action move occurs. So what happens if both fingers hit the screen nearly simultaneously is that the 2nd finger (should be pointer(1)) gets a move action before pointer down is called, making the code think it's a DRAG not a pinch zoom.

I have an Activity in which I have a TableLayout. I fill the table with TableRows in which I display TextViews. Imagine this as a classical table with text content. After the loop is finished I want to read all the heights in pixels of all the TextView in this table. I do this with getHeight(). The problem I have now is that ALL the values are 0 (zero) pixels. Even though I have text in the TextViews. The odd thing about this is, if I read the height of the exact same TextViews in an OnClickListener () then I do get the real height of the elements. Why is that so? I mean, nothing has changed in the height of those elements in the time between filling the table and firing the OnClickListener(). I really need to be able to get the height of the TextViews right after I filled the table. To get the heights upon a click is too late already for what I want to do.

I have a TableRow that is empty on compile time. The tablerow is supposed to be filled with a chart generated by JFreeChart during runtime. How do I add the chart into the tablerow?

I am using Tablerow+TextView to make a simple view for blog posts and their replies. In each TableRow I put a TextView in. Now I have two issues:
The text which is longer than the screen won't automatically wrap up to be multi-line. Is it by design of TableRow? I've already set tr_content.setSingleLine(false); [update]
This has been addressed, I think I should change Fill_parent to be Wrap_content in

The Table won't scroll like ListView. My rows are more than the screen size. I expect the table could be scrolled down for viewing just like ListView. Is that possible?

With the XML layout shown below, I have some views wrapped in a GestureOverlayView. As shown below, my first row is blended with the second row, as-if the first row is transposed right on top of the second. Now when I take the GestureOverlayView out of the code and leave everything else as-is, my table looks fine - the rows are separate and not on top of each other..........

I'm making a image gallery with infinite vertical and horizontal scrolling. I put images inside a ListView to make a column, and put the ListViews inside a TableRow. However, it seems that child views of TableRow is not selectable and as a result I can't select the images in my ListView (easily). Is there a way to pass the events down to child views of TableRow so they can be selectable?

I'm trying to access the textviews (for starters, eventually replace with imageviews etc) which are stored in the tablerows in the code below.
The line beginning 'log.d' was the part I was working on, trying to get it to print out the contents of the 2nd text view in the first row, but I can only get as far as selecting the tablerow using "getChildAt(i)".
Trying "getChildAt(0).getChildAt(1)" doesn't select the textview as I would have expected it to; says that it's a View and as such, doesn't have this method - though unless I'm mistaken, aren't tablerows ViewGroups, which do have this method? code...

I have a list in my app.
When a user touches a list item with their finger, the onListItemClick handler fires and I have it opening a new Activity.
However, when a user uses the trackball/pad to click, I want to perform some different functionality. I've overrode onTrackballEvent and everything works perfectly fine in the emulator's trackball mode.
Unfortunately, when testing on the Samsung Moment, clicking the trackpad fires the onListItemClick handler, not the onTrackballEvent handler.

Any experts on AlarmManager out there?I've got something weird going on.The basic code to set my repeating alarm works fine. I can close my app and the alarm will continue to run like clockwork every five minutes. It works fine only if I set it in the app and then close the app.I've got a registered BootReceiver for re-registering the repeating alarm. I know it fires on boot b/c the log message clearly shows it is firing and re-setting the repeating alarm in question for the same frequency. But the AlarmManager is not firing.Basically, the nearly identical code for setRepeating() fires when set from the app and continues to run when the app is closed, so I know my AlarmReceiver is functioning, but the AlarmManager is either not broadcasting this alarm or my receiver doesn't work from an alarm set in the boot receiver.

I have a grid view of buttons that is generated by a CursorAdapter. When the CursorAdapter is passed to the Gridview the view renders correctly however the first item in the grid does not fire the OnClickListener event.
If I select another button in the grid, the event fires correctly however if I selected the first button then another button, it loads the first button action then the section button action.
When testing this, it only seems to be an issue in Android 2.2 on my emulator, my 1.5 phone works as expected. I've wiped the emulator but that doesn't seem to have made a difference.

My app has been pretty stable for a while, and today out of the blue something called ProtoRequestListener has started intermittently throwing WatchDogExceptions. there's no path through to my code, so i can't even catch the exception and do something about it. i googled around a bit and it seems to be connected to Maps somehow.

I am working on my first android app and so my first with the Maps API and am experiencing an odd problem. How ever when I click the screen it seems the onClick event is not being run?Have I missed something or am I better off sub classing the MyLocationOverlay I am using and override DispatchTap?How ever i would rather be able to just click anywhere on the map to dispatch the event.

I am adding a proximity Alert with an expiration of -1 (does not expire). I am testing using an Evo. The proximity Alert fires several times after entering the location and staying inside the location. I was thinking that the proximity alert should fire once when you enter the location and fire once when you exit the location. Should the proximity alert fire multiple times after you enter the location and stay inside of the location?

I have created a parent class and a child class that inherits from it. When I set the OnClickListener in the child class, the event fires when the button is clicked. When I move the set OnClickListener to the parent class, the event doesn't fire. I've got to be missing something obvious but I just don't see it.

I'm creating a spinner and I've added an OnItemSelectedListener to it. However I've noticed that it fires on create. Now I was wondering if there was a way to ignore/discard it. I know I could use a boolean value, but that's a bit "dirty".

Have been using a SQLite database, Theres a situation where i have a list which displays all the "name" field data of a table "table1". Now i have a button to insert data in "table1". The list is populated using a simple cursor adapter which is passed a cursor "cursor1" populated with the data. "cursor1" is prepared using the SQLite query - "SELECT * FROM table1". Now the moment i insert data, i need to update the list too.
My question is- will the Adapter sense the database change automatically (i guess not)?
using cursor1.requery() is correct or should i use cursor1 = db.query("table1", null, null, null, null, null, null);

I've thought of some less than elegant ways to solve this, but I know I must be missing something.
My onItemSelected fires off immediately without any interaction with the user, and this is undesired behavior. I wish for the UI to wait until the user selects something before it does anything.
I even tried setting up the listener in the onResume, hoping that would help, but it doesn't. How can I stop this from firing off before the user can touch the control?

I am currently firing an Intent to a Broadcast Receiver which in turns starts an Activity.
Then from the same Service another Intent is fired to a Broadcast Receiver thats in the Activity.
The problem is that the Activity isn't getting the Intent meant for it because it is fired before it is alive and the Broadcast Reciever is registered.
I was wondering is there anyway to make sure an Activity is alive before sending an Intent?

We have an Activity which has a form on it and we launch an Intent to take a picture.We've overridden onSaveInstanceState and onRestoreInstanceState to push the data from the view fields But, on the return from the CameraActivity, the onRestoreInstanceState method is never called. Should this behavior work when calling another Intent?
