View 10 Replies View RelatedI am working on a MapView app in Android. I have three markers that I want to be able to use the Google Map API getlocation-function on, later on. In order to try it out I would like to move the marker with a drag and drop-function, and then check the location.
Anyone who has gotten a drag and drop to work on an android marker, or know a way to start figuring it out?
I am able to create and drag and drop activity successfully but the only problem I faced is if I drag the view more than about 30 times, the drag event will stop to initiate and I am unable to drag anything. What is the causes?I am using onTouch() to drag the view.
View 1 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 2 Replies View RelatedI am stuck in a situation,where I have onClick() method & onTouchEvent method. The situation is the my onTouchEvent is handling the fling gestures (like left,right), after each fling i am changing the Layout & presenting new one for the user. On each layout i have some buttons & they have the onClick() set. Now when i do the gesture nothing happens & sometimes the onClick gets called. how i can make these two methods to work correctly?
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?
View 2 Replies View Relatedi need left, right motion event and a click event . problem is that, if i have onclickEvent then onTouchEvent doesn't fire. onTouchEvent works only if i disable onclickEvent and also it doesn't work what i expect.
1-only ACTION_MOVE fires twice everytime when i move on screen.
2-can't get left and right motion.
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 1 Replies View RelatedI'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?

View 2 Replies View RelatedDoes anybody have any idea why I get often(but not always) error during the on touch event? Handling touch events is freezed for few seconds(this appears only immediately after application start). Then Error screen appears (choose wait of close). When I choose wait after few seconds screen is starting to process events. I'm using surfaceView with thread for painting. In logcat I get something like : "No window to dispatch pointer action 1".

View 6 Replies View RelatedI'm trying to do something in my app where you have to hold your finger on the screen for more than 30 seconds. After about 30 seconds, it stops sending onTouchEvents for that part of the screen, almost like a "dead zone." Tested on a motorola droid, and is there any way to stop this from happening?
View 6 Replies View RelatedI 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.

View 12 Replies View RelatedI 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.
It is possible to draw markers in runtime or at onLocationChange event, not on Create event?

Its function is to open a new activity when the button is clicked. So in the onClick function of the setOnClickListener() call, I created a new object of the Activity class and used that to call the various methods that needs to start the activity but I keep getting a java.lang.NullPointerException thrown regarding the line that calls the startActivityForResult() method. Not sure of the best way to go about this. I have pasted a sample code...
