This post from Nick Bradbury tackles an issue familiar to every Android developer: the ListView. In particular, Bradbury aims to help readers make their ListView scroll more smoothly, or as he puts it, "un-jank" them. He breaks the process down into four steps:

  1. Use the View Holder pattern
  2. Do as little work as possible in getView()
  3. Reduce unnecessary overdraw
  4. Flatten the view hierarchy

Rather than focusing on the ViewHolder pattern, which he takes as a given that most developers are probably already familiar with, Bradbury addresses other lesser-known issues (steps 2 through 4) that impact the performance of ListView scrolling.

For a few tips on cleaning up your ListView, check out Bradbury's full article. Or, for a more detailed, step-by-step tutorial, check out Antoine Merle's two-part series on ListView Optimizations here and here.
