title: setImageResource for an ImageView from another ImageView
body: <p>Strange request here, but is there any way you set an imageview to hold the same drawable as another imageview by getting it from the original imageview. what i mean is:</p>
  
  <pre><code>ImageView image1 = new ImageView(this);
            image1.setimageResource(R.drawable.blah1);
  
  ImageView image2 = new ImageView(this);
  
  //now i want something like this, which doesn't work. i  want to get it from image1
  image2.setImageResource(image1.getDrawable());
  </code></pre>
  
  <p>so please how can i achieve this from image1?.. Thank you :)</p>
