Android :: Drag And Drop From Source View To Target View
Sep 17, 2009I have a problem statement, and here it is: My requirement is: There are a number of images shown on the screen. I want to allow the user to drag and drop any of the images to anyother image. Based on which image is dragged and on which is it dropped, I need to do something specific. So, I need to find a way so that I can get my source view and my target view.To understand this in a better way, consider a practical scenario. In the File Explorer of Windows, we can drag and drop items from the left pane showing the directory tree to any of the folders shown in the right pane.If anyone of you ever faced a similar scenario, please let me know because I could not find a direct support to such a thing (Drag and Drop) in the platform, so may be I need to find an innovative solution to it.

View 1 Replies View RelatedAndroid :: OnTouchEvent Limited To 36x / Second?
Jan 12, 2010I've been pulling my hair out trying to achieve smooth scrolling in an OpenGL-based app on Eclair. It seems that no matter what I do, I cannot get more than 36 events per second (the rest is sent in history data which is useless in my case). This happens on both the emulator and the Motorola Milestone.Is this a hardcoded limit or am I doing something wrong? I'm implementing onTouchEvent on the activity and recording how many events are received per second and then send that info through Log.v to Eclipse. I also tried implementing onTouchEvent on the view instead of the activity and the results are the same.

View 4 Replies View RelatedAndroid :: Framerate Killed By OnTouchEvent Spam
Apr 27, 2009I've got a problem with a flood of touch events destroying my game's framerate while there is a touch active. Basically onTouchEvent is called (with getAction = ACTION_MOVE, x = 0 and y = 0) about a hundred times a second for as long as the finger is touching the screen. I've tried returning from onTouchEvent straight away, and even removing its implementation at all, but it doesn't help - the app slows to a crawl as soon as a finger is down. I asked on the IRC channel and Romain Guy advised me that they're aware of the problem but didn't have time to fix it for Cupcake, so I'm not expecting a full solution!

Dec 16, 2009I have several complaints from Moto DROID users who experience lags while touching. In my app I implement the recommended workaround with two threads and Thread.Sleep( 35 ) .

As I don't have a DROID, could someone please tell me if there is still a need for this workaround? Or shall I have to do anything else?

Android :: Detect Where On Screen OnTouchevent Happened

View 1 Replies View RelatedAndroid :: Sleeping In OnTouchEvent Blocks OnSensorChanged
Nov 13, 2010I'm making an application which will utilize both touchevents and sensorevents. The problem with touchevents is that they fire off very often, and thereby consumes massive amounts of CPU time. The common solution is to do a Thread.sleep to make it cool down.However, if one wants to use both the onTouchEvent and onSensorChanged in the same activity, applying the Thread.sleep hack will also slow down onSensorChanged. This is obviously caused by the two methods being called from the same (ui) thread.Is there some way to call onTouchEvent from a different thread than the ui, so one could do the Thread.sleep trick without slowing down onSensorChanged as well?

Feb 3, 2009Does anybody have any idea why I get often(but not always) error during the on touch event?

View 6 Replies View RelatedAndroid : Catching Button Behavior - Using OnTouchEvent Method To Capture ACTION_DOWN
Oct 20, 2010I need to specify the full button images for both the up and down positions. My impression is that the most probable choice is to use an custom button based on the ImageView and specify the image for up and down positions. I am using the OnTouchEvent method to capture the ACTION_DOWN, but I'm not getting the ACTION_UP event.
Is there a better choice for creating a button that controls the full button image, catches the Down/Up and can subdivide the down time into time slices? If not, how do I catch the up event.
My application expects a screen touch on the "button" and not a keyboard action.
Android :: How Do I Temporarily Disable / Bypass Android OnTouchEvent
Oct 2, 2010To provide feedback from the user for game I'm writing.This event fires off some game control events that take some time to complete (because there is animation involved).The problem I'm having is during the animation if I keep touching the screen (AKA firing this event),Basically while the animation is running, I do not need this event, although it would be nice to queue it.What can I do to prevent the timeout and either queue the event, or temporarily disable it?
View 2 Replies View RelatedAndroid :: Is Android OnTouchEvent Dispatching Accurate?
Jun 6, 2010I have a weird bug in my piano app. Sometimes keys (and thus notes) hang. I did a lot of debugging and narrowed it down to what looks like androids inaccuracy of motion event handling.Clearly it can be seen here that out of nowhere I suddenly have an ACTION_UP for another note. Shouldn't I definitely get a ACTION_MOVE first? As shown in the end of the log, it's definitely not an error in region detection, since the ACTION_UP event is clearly in the B4 region. Every onTouchEvent call is logged, so the log is accurate.

Android :: Populate View Flipper Child View With List View?
Aug 2, 2010I am trying to set up a ViewFlipper that changes a SlidingDrawers content each time a button is pressed. So far every view I set up worked fine, but now I am trying to create a ListView (including single_choice_mode) within a child view of the ViewFlipper, but my attempt only let to a NullPointerException. As I only discovered ViewFlipper today, I am not yet familiar with it and may not have understood it completely. if someone could give me a hand and help me find out what I have done wrong, that would be great. Here is what I have done:
The code for the onClick event of the ImageButtons:
public void onClick(View v){
if (v == btnExposure){
mFlipper.setDisplayedChild(0); }
else if (v == btnProperties){
mFlipper.setDisplayedChild(1);}
else if (v == btnSpecialEffects){
mFlipper.setDisplayedChild(2);.............
