Android: How to optimize ListView with ImageView + 3 TextViews?
<p>I've been looking everywhere to see if there is a standard way of achieving this but I find a different solution everytime. Basically, I am trying to build a Custom ListView with an image and two-three lines of text besides it. In order to optimize it, I understand that the following have to be used:</p>

<ol>
<li>convertView: Basically if the view was already inflated, use it</li>
<li>Lazy-Loading: Do not load the content of the rows until they are called for</li>
<li>Background Downloading &amp; Caching: Download images in their own threads and then update the row (and possible cache them?)</li>
</ol>

<p>I could manage 1 and 2 but the third one is really confusing me. Is there a best practice for this?</p>

<p>Thanks</p>
