Edit Question
Title
Body
I have a background image (a map) on which I need to regularly draw the you-are-here icon. I use Canvas to draw the icon on top of the map. Assuming that the drawing process is triggered on button click (see code below), how can I erase the previous drawing? private void displayUserPos(Point userPos) { Bitmap marker = BitmapFactory.decodeResource(getResources(), R.drawable.ic_yah); canvas.drawBitmap(marker, (float)userPos.getX(), (float)userPos.getY(), null); imgView.setImageBitmap(fmOverlay); }
