I have a thread where I will get some Bitmap one by one. Then whenever I get a new Bitmap I need to update my SurfaceView which in the main thread. How can I do this?

Answer 1

Here is some pseudo code

new Thread() {
    public void run() {
        while (bitmapIncoming()) {
            Bitmap bitmap = getNextBitmapAfterLongOperation();
            mActivityReference.runOnUiThread(new Runnable() {
                public void run() {
                    mActivityReference.updateSurfaceView(bitmap);
                }
            });
        }
    }
}.start();
