My Surface View is Not working

This is the main scenario: KillThemAll Game

In constructor of my CustomView which extends SurfaceView class, I set the background as :

this.setBackgroundDrawable(getResources().getDrawable(R.drawable.moon_light));

if I set background in one of the methods of SurfaceHolder.Callback(), the game and all the animations become freezed...

getHolder().addCallback(new SurfaceHolder.Callback() {

        @Override
        public void surfaceDestroyed(SurfaceHolder holder) {
            boolean retry = true;
            gameLoopThread.setRunning(false);
            while (retry) {
                try {
                    gameLoopThread.join();
                    retry = false;
                } catch (InterruptedException e) {}
            }
        }

        @Override
        public void surfaceCreated(SurfaceHolder holder) {
            createSprites();
            gameLoopThread.setRunning(true);
            gameLoopThread.start();
           setBackgroundDrawable(getResources().getDrawable(R.drawable.moon_light));
        }

        @Override
        public void surfaceChanged(SurfaceHolder holder, int format,
                int width, int height) {
        }
    });

why?

Looks to me you just want to draw a background. Since you have overridden onDraw() in your SurfaceView implementation to do animation, you should not rely on View methods to do drawing because they will conflict with your custom drawing.

@Override
protected void onDraw(Canvas canvas) {
    canvas.drawBitmap(background, 0, 0, null); // background replaces canvas.drawColor(Color.BLACK);
    // draw your sprites here
}

You just have to make sure background is a Bitmap that is bigger than the canvas size. You could also use drawBitmap (Bitmap bitmap, Rect src, Rect dst, Paint paint) to scale it to the right size but it won't respect the aspect ratio.

I think you're making a miskate on your src and dest rects.Try to print the values of both on the log and see whether they are correct

Replace this line

this.setBackgroundDrawable(getResources().getDrawable(R.drawable.moon_light));

with

bm = BitmapFactory.decodeResource(getResources(), R.drawable.moon_light);
