Question

I have this code:

protected void onDraw(Canvas canvas) {
    // TODO Auto-generated method stub
    super.onDraw(canvas);
    canvas.drawColor(Color.WHITE);
    canvas.drawBitmap(ball, (canvas.getWidth()/2), 0, null); 

and it draw bitmap on screen but if i want to set new position it draw new one, how can i draw a new one and erase previous one. I’d like to set new position of bitmap on canvas.

Answer 1

Drawing color first will erease all then draw your Bitmap with new position.
