android - 与 PreferenceScreen 的布局不同的布局

Question

我将 PreferenceScreen 用于我的设置。

该活动适用于@android:style/Theme.Dialog主题。所以一个对话框出现在我的主要活动中心！

它适用于 ldpi、mdpi 和 hdpi，但不适用于 xhdpi。switchpreferences 覆盖了我的标题项目！创建边距 =s

好（ldpi、mdpi、hdpi）：http: //img405.imageshack.us/img405/9212/sty.png

坏（xhdpi）：http: //img560.imageshack.us/img560/3529/c7k.png

这个怎么删？谢谢 ！
