我开发多个屏幕，所以我的布局布局，布局大型，布局XLARGE。这些布局的按钮的背景已经被张贴在绘制，华电国际，绘制-xgdpi，绘制-xxhdpi文件夹。

但是，当我运行应用程序，它似乎是布局选择可用的最可绘制最小。 xhdpi没有使用正确大小的图像。为什么是这样？我是否需要创建绘文件夹的单独结构？

I am developing for multiple screens, so my layouts are in layout, layout-large, layout-xlarge. The button background for these layouts has been posted in drawable-hdpi, drawable-xgdpi, drawable-xxhdpi folders.

But, when I run the application, it seems like the layouts are selecting the most smallest drawables available. xhdpi is not using the correctly sized image. Why is this? Do I need to create a separate structure of drawable folders?
