title: UI lags when setImage() to ImageView Android
body: <p>I have scrollView with LinearLayout inside.
  In this layout I add ImageView (by code) and start download bitmap from web (asyncTask).
  In postExecute I do imageView.setImageBitmap(result); result = bitmap from web.</p>
  
  <p>And when I scroll my scrollView I see lags when bitmap adding to imageView. Any ideas how to remove this lags?</p>
  
  <p><strong>EDITED</strong></p>
  
  <p>There is no lags when I comment:</p>
  
  <pre><code>//imageView.setImageBitmap(result);
  </code></pre>
