title: Tiled drawable sometimes stretches
body: <p>I have a ListView whose items have a tiled background. To accomplish this, I use the following drawable xml:</p>
  
  <pre><code>&lt;bitmap
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:src="@drawable/tile"
      android:tileMode="repeat" /&gt;
  </code></pre>
  
  <p>Usually, this works. Sometimes, however, the src drawable isn't tiled, but stretched to fill the entire list item. (I've got several different tiles like this, and I use them mixed in one ListView. If there is stretching instead of tiling, it's never been in all of them at once, for what that's worth.)</p>
  
  <p>I also tried to add <code>android:dither="true"</code> to that xml, since I read somewhere that without it there might be bugs. That didn't change anything.</p>
  
  <p>Has anyone had the same problem? How did you fix it?</p>
