title: RecyclerView: Async image-loading
body: <p>Im using <code>RecyclerView</code> to display a list containing an <code>imageView</code>. To make the UI more fluently, I load 58dp thumbnails saved on sd card into these imageViews with an <code>asyncTask</code>. </p>
  
  <p>The problem is, that once a <code>childView</code> comes in visual display, an old image from another data is being reused and then replaced once the <code>AsyncTask</code> finishes. I can stop the shuffling by setting the <code>imageView</code> bitmap to null in <code>onPreExecute</code>. </p>
  
  <p>Is there a way to really reuse old images or do I really have to load the images from sd-card each time a new <code>View</code> comes in place? This makes view quite ugly because either there are wrong images first or the image is plain white.</p>
