title: how to make my list with generated bitmaps work smooth?
body: <p>hi i have a problem with a android app. i have a list which contains a bitmap and a string.</p>
  
  <p>the bitmap is always generated via the <code>BitmapFactory</code>. I dont have this in a own thread, so when the list gets long, the loading of the page takes a lot of time.</p>
  
  <p>now my question:</p>
  
  <p>what is the easyest way to make this smooth for the user so he dont have to wait. the best way would be to show the strings first and then show a loading bar fpr each bitmap and then generate it one after the other.</p>
  
  <p>but should i make this with one additional thread or one thread for each image?</p>
