I've got an onTouchEvent boolean on a Surfaceview, I've got openGL objects drawn on the view and I'm wondering is there anyway to detect where on the screen the onTouch happened? e.g (x,y) co-ordinates.

View 9 Replies View RelatedI am looking for a way in which I can detect any tap on the screen (not just in my app), I don't mind not having the information of what the tap was (control/letter), just the fact that a tap was made will suffice for me for now. Is there any possible way to achieve this?
View 4 Replies View RelatedAs mentioned in a previous question, I am having difficulty intercepting all android.intent.action.SCREEN_ON events without a long-lived service (discouraged). I may be able to work around the need if I can simply work out when the screen is on at any given time, in the service.

I recently bought a HTC Desire which I've become exceedingly fond of.I've read (and been told by a colleague who owns a HTC Legend) that wifi should automatically turn off while the screen is off to conserve battery. I have the impression that I should be able to see the wifi icon turn on as I turn on the screen and unlock the phone. However, I haven't noticed that happening: The icon seems to just be on always.I have then tried observing my router's DHCP table when the the screen is off, but I haven't observed the entry for my phone disappearing (and I don't really know how much time has to pass before the table not showing my phone.Are there any settings that can cause this behaviour? What about programs? I current use smart monitor to log data usage as well as locale (using a SSID plugin and not the locale "location" condition). The only services I can see apart from those I think are OS services, are the ones for locale, smart monitor lite and the SSID plugin.
View 5 Replies View RelatedI'm writing a customized view similar to Grid which will be used to hold a large amount of images. I'm using ImageButton to display the images, and I only want to load images onto the buttons once they are on the screen (and just display a static background image when they are not). The reason for it is that I'm fetching images from some back-end service and I only want to fetch them when the buttons are on the screen.To do that, I'd like to know if the widget is on the screen. Is it possible to detect if a widget like button is on/off screen? If not, any suggestions on how to achieve what I'm trying to do?

View 10 Replies View RelatedI have a motion listener to detect finger down, finger drag, and finger up. I start my action at finger down and finish my action at finger up. When the action is finished, I store it in a stack for allowing undo. My problem is that if I don't get a finger up event, I can't finish my action to add it to the stack for undo.
How can I detect that the user's finger has left the screen?
I tried using the emulator to see if getEdgeFlags() ever returned anything useful, and the result was always 0.
Basically, if a finger leaves the screen, then nothing is touching the screen anymore and I would like to detect that as a finger up event. How can I do this?
Is there any way where I can detect that the screen is about to turn off, so I can do some work *before* it happens?I need this to work around bug 3755: OpenGL apps sometimes crash when the screen gets turned off because they don't get surfaceDestroyed /surfaceCreated() events. Simply put, I need to shut down OpenGL before the phone has a chance to detach the GPU. The only events I seems to be getting when the screen turns off are onPause() and onWindowFocusChanged both of which turn up *after* the GPU detaches, by which time it's too late.

View 1 Replies View RelatedI'm currently implementing a live wallpaper. This is also visible, when the device is locked. Now I want to show different content, when it is locked but can't find a way to detect this. PowerManager can only change the settings and the wallpaperEngine only gives me a general onVisibiltyChanged() method, which triggers every time you return to the home screen.Dos anybody know a way to detect if the device is locked?

I've got a site that slides up a little info panel when the user hovers their mouse over an item. I'm using jQuery.hoverIntent to detect the hover, but this obviously doesn't work on touchscreen devices like iPhone/iPad/Android. So on those devices I'd like to revert to tap to show the info panel.

View 3 Replies View RelatedI'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 RelatedI am trying to detect if the screen size is normal, large or small. I am using
Configuration conf =view.getResources().getConfiguration();
(conf.screenLayout&Configuration.SCREENLAYOUT_SIZE_MASK) == Configuration.SCREENLAYOUT_SIZE_NORMAL
When testing with the emulator this works for screen sizes normal and small, but large (480x800 & 480x854) returns that it is normal...
I have found very little information on using the configuration to detect the group, has anyone got any experience with this?

View 4 Replies View RelatedI was using my phone (droid 3) and the app I was using force closed, my phone lagged for a few seconds and then I just put it down so it could catch up. While waiting the screen timed out and when I went to use it I could not unlock it. I can press the button on top and it will turn the screen on or off, and if I hold it it will bring up the power off menu. I tried to call it, and it went through. I got the normal screen to answer it, but I could not answer it. After I hung up I got the notification for a missed call. Everything seems to be working, my screen just does not respond to a touch. What should I do?

View 4 Replies View RelatedI'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!
View 3 Replies View RelatedI 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 ) . It worked and works perfectly on my G1 and on some other Google devices. But for DROID I hear many complaints. 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?
