title: Android. How do I keep a button displayed as PRESSED until the action created by that button is finished?
body: <p>I have <code>button_focused</code>, <code>button_pressed</code>, and <code>button_normal</code> images. When I press the button, the <code>button_pressed</code> image is displayed and the action related to the button pressing begins. </p>
  
  <p>When I quit pressing the button, the action continues but the button returns to <code>button_normal</code> image being displayed.</p>
  
  <p>How can I set the button image being displayed to <code>button_pressed</code> during the entire action then reset to the <code>button_normal</code> image?</p>
  
  <p>Thank you for your time</p>
