Taking screen shot of a SurfaceView in android

Question

I am using following method to taking screen shot of a particular view which is a SurfaceView.

public void takeScreenShot(View surface_view){

    // create bitmap screen capture
    Bitmap bitmap;
    View v1 = surface_view;
    v1.setDrawingCacheEnabled(true);
    bitmap = Bitmap.createBitmap(v1.getDrawingCache());
    v1.setDrawingCacheEnabled(false);

    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    bitmap.compress(CompressFormat.PNG, 0, bos);
    byte[] imageData = bos.toByteArray();

}

the problem is its giving me the whole activity screen image. But I need to take screen shot of the particular view. I tried other ways but those give me a black screen as screen shot, some posts says that it requires rooted device. Can any one help me please. I'm in need of this solution. Help me....

Surface view is a view but item on surface view like bitmap or other object are not any view. So while you capture surface view it will capture every thing on the surface. You have to use other view like image view or other above the surface view and then capture those view.

First get the view whose picture want to take then do this

            Bitmap bitmap;
            View rv = **your view**
            rv.setDrawingCacheEnabled(true);
            bitmap = Bitmap.createBitmap(rv.getDrawingCache());
            rv.setDrawingCacheEnabled(false);

            // Write File to internal Storage

            String FILENAME = "captured.png";
            FileOutputStream fos = null;

            try {

                fos = openFileOutput(FILENAME, Context.MODE_PRIVATE);

            } catch (FileNotFoundException e1) {

                e1.printStackTrace();
                Log.v("","FileNotFoundException: "+e1.getMessage());

            }

            try {
                bitmap.compress(Bitmap.CompressFormat.JPEG, 90, fos);
                fos.flush();
                fos.close();

            } catch (FileNotFoundException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
