How to make Android UI focus move smooth?
<p>In <code>ListView</code> and <code>GridView</code> ,when the focus moving looks so stiff.I try to  encode the <code>onDraw</code> function myself,but doesn't look better.</p>

<p>Then I use a class that inherit <code>LinearLayout</code>,realize all function of <code>SlidingDrawer</code>,also has right sliding.but It doesn't look that desirable.I don't know how to make the focus move look better.thanks for helping.</p>
