Android :: Can't Intercept The OnTouch Event Of PopupWindow
May 26, 2009
I want to intercept the OnTouch event in a PopupWindow, but it failes everytime. Here is the code snip:
CODE:.....................
When the activity started, I can click the button to show the popup window correctly. But after that, nothing happens when I touch the popup window's view. But if I touch any where outside the popup window, the log Log.d("Demo", "layout::onTouch >>> view: " + v + ", event: " + event); will work.
It looks like when I touch the view of the popup window, the touch event has been consumed somewhere?

I am relatively new to this still, and I have been developing a small app that would benefit greatly from a user being able to press 2 buttons at one time. What is the best method for achieving this? I dont think that an OnClickListener works like that, and I have seen examples for doing this with an OnTouch event. However, I do not know how to set up button presses with an OnTouch event.

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 a situation where I have some textview on a framelayout that I have a onTouch event wired in order to simulate dragging. I alos want to enable the ability to have a context menu display when the user long presses the textview. Now that I have implemented the context menu functionality dragging no longer works since the longpress is always served by the context menu event.Does anyone know of a workaround for this.

I'm trying to start activity by sweeping across the screen, it works fine for all the other screens, just this screen that doesn't fire the onTouch at all? Would you mind helping me? I've tried debugging it and still have no idea at all. Below are the codes, sorry for not putting snippets only as I thought I might did something wrong elsewhere
I'm also looking for advice on implementing sweeping to change screen. I've read about ViewFlipper and I know it will work very well, but I've around 8 screens with different backend coding needed.
CODE:.....................

Let's say I have MyActivity and inside my onCreate method I initialize MyBackgroundView, then MyPlayer1View then MyPlayer2View. I want to be able to touch the screen, figure out if I have touched Player1 or Player2 and then respond with changes to the players if I have touched them.
My problem is, where do I put the onTouchListener? Can only MyBackgroundView listen for touches, or can the players listen for touches too? If MyBackgroundView can only accept touches, do I need to call view.ontouchlistener that says, you have touched me, and I have a player at those coordinates, so I'll pass the motion event to the player and let it handle it? Or do call view.ontouchlistener in each of the players that says, you've touched me, now I will react to the motion event?

I looked online and was not able to find a working example of the PopupWindow class. The code examples I found online either compile but do not work, or are using methods which have since been removed (such as Activity.getViewInflate()). Is there a simple working example that displays a PopupWindow?

I am trying to make a PopupWindow show straight away when an activity has started.
when calling public void showAtLocation (View parent, int gravity, int x, int y)
I get the exception ERROR/AndroidRuntime(2500): Caused by: android.view.WindowManager $BadTokenException: Unable to add window -- token null is not valid; is your activity running?
At the moment I am calling from onCreate, but when calling from onStart or onResume it still gives the same error.
The activity api says the activity is supposed to be running after onResume is called. Where is the best place to load up the PopupWindow if it needs to be done straight away?
At the moment It looks like Activity.onWindowFocusChanged() is the best place.

I've experimented with a PopupWindow, but don't have a very good way of controlling its size. It only responds to absolute pixels.

i tried to use my popupWindow with some enter/exit animations - it has setAnimationStyle() method for that purpose. after some time i realized i cannot use my own custom animation styles which is ok but a bit limiting. so i tried system ones: R.style.Animation_Toast works ok, but R.style.Animation_Dialog doesn't. looking at xml definition files i found that Toast animation uses simple alpha animation and Dialog animation is a set of alpha combined wit scale animation. is it a problem for WindowManager to deal with complex animations?

I have a gridView that I display in a popupwindow (the gridview is in a transparent layout, which inherits from linearlayout and just has a partially transparent background). I can never get this GridView's OnItemClick to execute. When I touch an image in my gridview it appears to be clicked (image bachgrond changes), but OnItemClick is not being called.
Below is the code for my Adapter and my popupview containing the gridView.

I am displaying google map and on top of that some overlay items(Markers) are there. When tapping on the markers, I need to display PopUpWindow. The code is executing but popup is not displaying.
popUp.showAtLocation(layout, Gravity.TOP, 0, 0); popUp.setFocusable(true); popUp.setTouchable(true); popUp.setOutsideTouchable(false); popUp.update(0,50, 320, 70);
Here layout is an object of LinearLayout.
I created another android application, in that, I put the above code and its working perfectly. PopupWindow is displaying.

I would like to be able to either blur or dim the background when I show my popupwindow using popup.showAtLocation, and unblur/dim the background when popup.dismiss is called.
I have tried applying layout params FLAG_BLUR_BEHIND and FLAG_DIM_BEHIND to my activity, and this appears to just blur and dim the background as soon my app is started.

Requirement: 1. The program must be on top of SDK only, no hacking! 2. When a TEXT SMS is arriving to Android mobile, the program must intercept the TEXT SMS to analyze the SMS content (access the whole SMS data) 3. In terms of the SMS content, the program determines if the SMS is erased as it doesn't exist. No notification, no update to Inbox UI. 4. Power cycle the Android phone, the SMS is not seen at Notification or message Inbox
Can any one help with the solution? Or which API shall we look into?

I am wondering if it is possible to intercept an open application call, for any (most of the) installed application. Or at least for opening the Activity having the intent-filter's action set to Main (if it exists for an app).
