ActionBarSherlock背景的图像大小(Image size for ActionBarSherlock background)

 如果我要获得一个旨在用作ActionBar背景的艺术资产，我应该要求什么尺寸（以像素为单位）？ 我发现引用ActionBar大小的所有东西都在dp中，所以我不确定与实际的.png文件一起使用的最佳绝对大小。 谢谢！ 

If I were to get an art asset made intended for use as the background of an ActionBar, what size (in pixels) should I request? Everything I have found referencing the size of an ActionBar has been in dp, so I'm unsure what would be the best absolute size to go with for the actual .png file. Thanks!

 根据配置，操作栏的高度可以是40,48或56 dp。 这意味着，由于Android如何通过密度来缩放内容，因此有9种不同的绝对像素高度。 当然，宽度取决于设备。  
 您最好的选择是使用9-patch drawables或使用形状XML创建drawable，以便它可以适应几乎无限数量的设备配置。 

The action bar can be 40, 48, or 56 dp in height depending on configuration. This means that because of how Android scales things by density there are 9 different absolute pixel heights. The width varies depending on the device, of course. 
Your best bet is to use 9-patch drawables or create the drawable using a shape XML so that it can adapt to the nearly infinite number of configurations of devices.
