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.
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.
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:
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.
This should be a simple question because I couldn't get the answer from Google . I have ListView in a LinearLayout . I need to handle the click event to allow user click on the LinearLayout to trigger some function. I try to add onClickListener to the LinearLayout , and it works only when I click outside of the ListView . How do I let the click event on ListView propagate automatically to be handled by the Listener of the LinearLayout?
I have a ListView whose rows are formatted by me. Each row has a mix of ImageView and TextView. I have also implemented my own adapter and am able to draw each row through it.
Now, I would want something like this-
User clicks on an ImageView (not anywhere else on the row, but only this ImageView should respond to clicks) I get to know the position of the row whose ImageView was clicked.
I have tried many things for this and have wanted my code to be as efficient as possible (in terms of overkill). Currently i can capture the click event on that particular ImageView only, but I can't know which row was clicked.
I have provided an attribute in the Row XML like this-
And in my code, I have a method like this:
I can get the parent row (perhaps) but am not sure how to go further from here.
In my application i have a button initially on the screen and in onclick of the button ,popup window should open. In the popup window i have an imagebutton , now on click of this button i want to start an activity. The popup window opens but i dont understand how to handle the onclick of the imagebtn inside popup window.
In main.xml i have a button and in popup_example.xml i have an imagebutton.
I could not figure out how to implement two basic functionalities with the expandable lists: 1. The onClick for the child 2. Using linear layout for the children, so that I can have multiple clickable items in same row under the parent item
Can somebody help me with some sample code for the above?
I use onLongClick and onClick events of a button to get user inputs. Whenever; the user long click and triggers onLongClick event, the onClick event is also triggered. I couldn't find my problem. The code of two methods are shown in below: Code...
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 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);
