推荐答案

如果你只是想获得它的下拉菜单，将一路的权利，而不是狭窄的，你可以设置标签上的微调XML使用的android：layout_width =FILL_PARENT。如果你想只是有没有边框的按钮，Android的preferences有自己的布局对象。我刚才问别处如何让非preferances鉴于这些元素：<一href=\"http://stackoverflow.com/questions/5836132/howto-make-a-layout-similar-to-the-ones-in-settings\">Howto做类似设置的那些布局。

If you are just trying to get it the dropdown to be all the way to the right rather than narrower, you can simply set the tag on the spinner in the xml to use android:layout_width="fill_parent". If you want to just have the button without the border, the Android Preferences have their own layout objects. I have just asked at elsewhere how to get those elements in a non-preferances view: Howto make a layout similar to the ones in settings.
