I want to create a simple Map based application in android ,where i can display my current position.Instead of overlaying a simple Image on the MapView to represent the position, i want to overlay the GLSurfaceView on the MapView. But i don't know how to achieve this. Is there any way to do that?. Please anybody knows the solution help me.

I am trying to merge two examples from the ApiDemos so one overlay over the other. 1. CameraPreview.java 2. TranslucentGLSurfaceViewActivity.java I guess GLSurfaceView is not really necessary, I saw demos that uses a GL layer as a Camera PreviewCallback, but since I am such a noob at OpenGL, I am kind of lost. Can someone points me toward the light (figuratively speaking)?

View 4 Replies View RelatedI have subclassed Overlay as LandMarkOverlay (and implemented an onTap(GeoPoint) method).
In the main activity I do this:
setContentView(R.layout.main);
MapView mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
landmarkOverlay = new LandmarkOverlay();
//add the landmarkOverlay to the list
mapView.getOverlays().add(landmarkOverlay);
What else do I need to do so that when the user taps the screen, landmarkOverlay's onTap(GeoPoint) method gets called?

View 1 Replies View RelatedI am trying to overlay route data in KML files on a MapView.
The following code works great:
CODE:................
The only problem I have with this is that I don't need to re download these KML files every time. I have about 10-15 KML files that will rarely change. Also since it has to connect, download, and parse these each time there is a delay in opening the maps.
It would make a lot more since for me to save these as a local resource and have the URI reference it there. Is there a way to construct a URI using the geo: scheme and have it point towards a local resource?
It looks like file:///sdcard support was included in 2.1. The only reference I could find to it was at the end of this bug report thread. I am currently at work and don't have time to play with this yet but I would like to figure it out later. I feel like there are a lot of people on stackoverflow and elsewhere who would really appreciate a reasonable way to do this.
I like tu use the MapActivity to display some pins. When a pin is pressed i like to open a description. This can I obtain following the tutorial: http://developer.android.com /resources /tutorials/views/hello-mapview. But now I like to put a button on the overlay window. That button should open a detail activity. How can I make this? How is possible to personalize the overlay "info window"?

View 2 Replies View RelatedFollowing the samples and examples, I've successfully been able to load a model on screen and rotate it with the DPAD keys and overriding the onKeyDown method of the GLSurfaceView. Trying to use a letter though, causes a small box to appear at the bottom accepting the text that is being typed. What I'm not entirely clear on, is since I don't have a listener defined in the main Activity, why those key letter key presses are being intercepted by some other inherent listener(?). I setup an OnKeyListener for the view to call my own method and that does work... but I'm wondering if there is perhaps a better way to handle it.
View 3 Replies View RelatedI am a lazybones using GLSurfaceView and loving it. But now that my code is running too darn fast (heh), I would like to slow it down via setting eglSwapInterval to 2 or something. Just to be nice to the battery. But, being a lazybones, I can find no way of doing this when using GLSurfaceView. (and hacking an early return from onDrawFrame() was very unsatisfying).

View 12 Replies View RelatedWe are developing an application that uses a GLSurfaceView to display 3D objects. We regularly get the "Application Not Responding" dialog. Inspection of the dumped threads reveals something that looks suspiciously like a deadlock. I have added the three thread dumps involved below. The first thread is the main application event thread, and it is waiting on a join with a GLThread.
The second thread is a brand new GLThread that is waiting for a semaphore lock presumably so it knows it has exclusive access to the graphics hardware. The third thread is probably a previous GLThread (the one the main thread is waiting for to finish), that is waiting to be notified. The strange thing is that the main application thread has just done a "mDone=true; notify();" prior to calling "wait()", so the third thread should have been awaken? .........................

They show that it is possible to put an GLSurfaceview on top on a SurfaceView. I hope it would be useful.
I'm using GLSurfaceView to create a simple OpenGL drawing application. Since the elements drawn in each frame must remain on screen in order to be composed into the whole drawing, I don't use gl.glClear(GL10.GL_COLOR_BUFFER_BIT) at the beginning of each frame. But not clearing the color buffer leads to substantial flickering. Is there any way to eliminate flickering while still not clearing the screen at the beginning of each frame?
View 7 Replies View RelatedI am able to get a GLSurfaceView to have a transparent background with:
CODE:............
when I set the Activity's window background to transparent and the GLSurfaceView is the contentView of the Activity.
But, let's say my GLSurfaceview is parented by a ViewGroup and I want GLSurfaceView bg to be transparent to see the Viewgroup's background - I am not able to do so with the code above. Is this a limitation or am I missing something?
I have an application that uses GLSurfaceView to draw OpenGL ES graphics. This is all working (mostly) how I would expect.
Now, I would like to implement a screenshot feature. For normal views, it seems that the standard practice is to create a new Canvas with a Bitmap and then draw to that Canvas using View.onDraw(Canvas).
I've tried using SurfaceView.draw(Canvas) in a similar fashion, but it always results in a blank (black) image.
I've also tried using the drawing cache with the exact same result.

I am currently porting a 3D app on Android. This app consists of a 3D view (embedded in a GLSurfaceView) and of menu screens (for settings, search , etc.).
My main activity is the one containing the GLSurfaceView. It's always the root of it's task. The problem is that my GLSurface gets destroyed whenever I launch another activity and all the GL objects (VBOs, textures) that I created in the GL context get deleted/invalidated along. So whenever my users go in the menu, the 3D scene has to be fully reloaded. Wouldn't there be a way to prevent the surface's destruction ?
as there's a GLSurfaceView in use, no other views receive any KeyEvents. MotionEvents however, are still working as expected. Is there a way to prevent GLSurfaceView from swallowing all KeyEvents?
View 4 Replies View Relatedwhat puzzle me so much is that i can't destroy a GLSurfaceView while i don't want to exit the activity.
the fact is when i destroy a GLSurfaceView which had show in the screen (that means it has binded to the activity's SurfaceHolder), the activity exits without any prompting. Perhaps ,the Context which provided in the Construction of GLSurfaceView joins the two things together. so my conclusion is that a GLSurfaceView can only be destroyed when exit the activity. is there anyway to destroy a GLSurfaceView without exit activity? is there someone can provide a clue?
Having a little trouble working out how to have a context menu working in my GLSurfaceView view. There doesn't seem to be a "onCreateOptionsMenu" or "onOptionsItemSelected" to override. I do notice a "setOnCreateContextMenuListener" but I don't know how to use it.
View 5 Replies View RelatedThe Emulator draws line widths VERY incorrectly in OpenGL (GLSurfaceView). See http://www.flickr.com/photos/53002505@N03 for a comparison of the lines drawn correctly (in JOGL) and incorrectly in the emulator. The code also draws correctly on a real device (G1) - looks just like the JOGL screen shot. I believe this is a bug. However, I'm not an OpenGL GURU. Hence I have posted a concise version of the code to demonstrate this problem at at http://gist.github.com/523955 and http://gist.github.com/523961. I hope I am proven wrong about a bug in the emulator, and can find a way to use the emulator for what I want to do.
