推荐答案

您可以拥有自己的对话框布局（见文档），但我会建议离开它是，因为这个对话框将另眼相看的HC / ICS / JB，所以调整其外观是相当糟糕的主意作为Android的其它版本也可能有所不同。这只是OS做它的方式。离开它是我的忠告。

You can have your own dialog layout (see docs), but I'd suggest to leave it as is, as this dialog will look differently on HC/ICS/JB, so tweaking its look is quite bad idea as on other versions of android it may look different. It's just the way OS does it. Leave it is my advice.
