title: Accessing Android drawable resource with a string
body: <p>I apologize if this seems really simple but I can't figure it out. I have an ImageButton that I want to change the image of at run-time based on a button click. I have 5 images in my res folder. When the user hits the "Next" button, I want it to go to the next image. The file names of the images are image1.png, image2.png, etc.</p>
  
  <p>I know I you can change the image by doing:</p>
  
  <pre><code>imgButton.setImageResource(R.drawable.image2);
  </code></pre>
  
  <p>I have a counter (int) to keep track of the image number being displayed. But how would i change the image to the next image? Any help would be appreciated.</p>
