Android :: Not Able To Draw A Transparent Image On Surface View / Fix It?

Jul 6, 2010

My objective is to run a glowing animation on an image.I am changing the image alpha to produce this effect.

I have used basic AlphaAnimation provided in android framework but found that its slowing down other animations. So i extended a class from SurfaceView and created a thread to update it. ( Again here, i am manipulating alpha of the image ).

Everything seems fine, except that i am not able to draw a transparent image onto SurfaceView.Its showing black color on the transparent areas of the bitmap.code...

Android :: Possible To Start Surface View With Game Thread

Aug 7, 2010

I've read several example programs and tutorials to try and solve my problem but they all seem to go the same way. I've used a couple Activities and xml documents to create a menu that loads when my game starts.When the user clicks the "Start The Game" button, it loads a new Activity that sets the view with my game thread and all of the game properties.I know this activity works because I've run it alone as its own project, but every way I've tried to start it after the Menu,I get a nullPointerException and it force closes.I read the SurfaceViewOverlay tutorial and attempted to use that implementation, but I'm using a SurfaceView, not a GLSurfaceView.I'm debating rewriting my entire program to use OpenGL but I figured I would see if anyone else knows what I'm doing wrong here.If you need the code snippets I can paste some here, but it's not really the specific code that's wrong.

Android :: GL Surface View GlText Image2D GlDrawTexiOES

May 3, 2010

I'm trying to render a 640x480 RGB565 image using OpenGL ES on Android using GLSurfaceView and Native C code. Initially I had a 0x0501 error with glTexImage2D, which I was able to resolve by changing the image dimensions. But now, in the "drawFrame" call, when I do glDrawTexiOES to resnder the texture, I'm getting the following error on the Logs: drawtex.c:89: DrawTexture: No textures enabled I'm already doing glEnable(GL_TEXTURE_2D), is there anything else I should do? Is there a complete example showing GLSurfaceView with native code using textures?

Android :: How To Draw Overlay On Surface View Used By Camera?

May 29, 2010

I have a simple program that draws the preview of the Camera into a SurfaceView. What I'm trying to do is using the onPreviewFrame method, which is invoked each time a new frame is drawn into the SurfaceView, in order to execute the invalidate method which is supposed to invoke the onDraw method. In fact, the onDraw method is being invoked, but nothing there is being printed (I guess the camera preview is overwriting the text I'm trying to draw).

This is a simplify version of the SurfaceView subclass I have:

public class Superficie extends SurfaceView implements SurfaceHolder.Callback {
SurfaceHolder mHolder; public Camera camera; Superficie(Context context) { super(context);
mHolder = getHolder(); mHolder.addCallback(this); mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
} public void surfaceCreated(final SurfaceHolder holder) { camera = Camera.open();
try { camera.setPreviewDisplay(holder); camera.setPreviewCallback(new PreviewCallback() {
public void onPreviewFrame(byte[] data, Camera arg1) { invalidar();
} } ); } catch (IOException e) {} } public void invalidar(){ invalidate(); }
public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) {
Camera.Parameters parameters = camera.getParameters(); parameters.setPreviewSize(w, h);
camera.setParameters(parameters); camera.startPreview(); }
@Override public void draw(Canvas canvas) { super.draw(canvas);
// nothing gets drawn :( Paint p = new Paint(Color.RED);
canvas.drawText("PREVIEW", canvas.getWidth() / 2, canvas.getHeight() / 2, p);
} }

Android :: Open GL Surface View Renders Black On First Start

Apr 1, 2009

I have an Activity that was created based on the TriangleRenderer example. It works flawlessly as a standalone project, but when I use it as the tab of a tabhost there is a problem. At startup the whole activity is just black - I can get touch events and do everything else but it doesnt show anything. When I change the orientation (and therefore recreate the activity) it all works well. Maybe the problem comes from the View focus. My SurfaceView is not focused when created inside of the tabhost. I tried to fiddle around with the methods available in my onCreate() and onPostCreate(), but couldnt find a way to get the SurfaceView focused. The following sourcecode blocks in the guardedRun() method because needToWait() is true because !mHasFocus is true. If I exclude the ! mHasFocus, it goes on but shows a black View anyways. Do you have any idea why it does work after orientation change, but not at the first startup? The Activity looks quite simple.

Android :: Overlay Images Onto Camera Preview Surface View

Aug 23, 2010

I have a SurfaceView that is being used to draw custom animations and I would like to overlay them onto a live-feed from the phone's camera. Currently, the SurfaceView that contains the animations has a white- background, but if I were to overlay them onto the phone's camera feed, they would have to be transparent. The camera and animation drawing cannot be done on the same SurfaceView. Is it possible to make a SurfaceView transparent? What is the best course to pursue the use of multiple views? My end goal is to essentially overlay the contents of another SurfaceView onto the Camera SurfaceView.

Android :: View Image In Action View Intent?

Nov 16, 2009

I'd like to show a png or jpg I downloaded from the next in an image viewer intent, but can't get it to work.

Bitmap bmp = getImageBitmap(jpg);
String path = getFilesDir().getAbsolutePath() + "/test.png";
File file = new File(path);
FileOutputStream fos = new FileOutputStream(file);
bmp.compress( CompressFormat.PNG, 100, fos );
fos.close();
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(path)), "image/png");
startActivity(intent);

I know the bitmap is downloaded ok (use the same routine for supplying it my ImageView instances elsewhere in my app) - I think it wrote to file ok, I can see it on disk and the file size is correct. The intent is launched but an exception is thrown: then the new activity just sits there, blank. How does this work?
