title: set source of ImageView dynamically android
body: <p>I have an ImageView on my scene that I would like to set the source of dynamically based on user input.</p>
  
  <p>Let's say I have 4 images in my drawable folder: aaa.png, bbb.png, ccc.png, and ddd.png.</p>
  
  <p>When my application loads I set the image to: aaa.png</p>
  
  <pre><code>myImageView.setImageResource(R.drawable.aaa);
  </code></pre>
  
  <p>now I have an EditText where a user can type in bbb and I want to change the image source to be the bbb.png, or user enters ccc, change source to ccc.png etc.</p>
  
  <p>how can I dynamically set the parameter in setImageResource()?  I tried playing around with the Drawable object to no avail...</p>
