body: <p>In my Android application i am retrieving all the gallery pictures and display in grid view.
  I have implemented the loading of images on Async task by using following reference link:-
  <a href="http://developer.android.com/training/displaying-bitmaps/process-bitmap.html" rel="nofollow noreferrer">http://developer.android.com/training/displaying-bitmaps/process-bitmap.html</a></p>
  
  <p>It is working fine.</p>
  
  <p>My gridview looks like this</p>
  
  <p><img src="https://i.stack.imgur.com/iLecg.png" alt="enter image description here"></p>
  
  <p>But i want to progress bar on loading images like this</p>
  
  <p><img src="https://i.stack.imgur.com/kh9v6.png" alt="enter image description here"></p>
  
  <p>Also if it is easier default image in place of loading images instead of progress bae will be fine.</p>
  
  <p>Please provide me solution to implement this.</p>
