title: how to add second image on ImageView
body: <p>I am a beginner Android developer, so I'm sorry if the answer to this question is obvious.</p>
  
  <p>I want to add two pictures to <code>imageView</code>. The first picture will be bigger and its position won't change. And the second will be smaller and its position will change, vertically (I think there is 16 combinations where it could be located). The position of the second image will change only when the user presses the button. Is there any way to set two pictures into one bitmap and then draw them to <code>ImageView</code>?</p>
