推荐答案
好吧，所以你必须要知道的是，支持屏不会使你的应用程序的外观您所支持的屏幕好（检查此链接）。它只是告诉用户这样的屏幕就可以下载你的应用程序，但它是由你来使其正常显示。你必须创建你自己的特定的屏幕布局。
Ok, so what you have to know is that support-screens doesn't make your application look 'nice' on screens you are supporting (check this link). It just tells that users with such screens will be able to download your application, but it's up to you to make it display properly. You have to create layouts for specific screens on your own.
更多关于它，你可以Android的文档中写着： http://developer.android。 COM /引导/做法/ screens_support.html
More about it you can read in Android's documentation: http://developer.android.com/guide/practices/screens_support.html
基本上，你必须正确地命名的目录中，布局文件存储在为了让Android的知道哪一个应该拿起特定设备。例如，如果你的布局的文件是layout.xml你应该有：
Basically, you have to properly name your directories in which layout files are stored in order to let Android know which one should it pick up for specific device. If for example your layout's file was "layout.xml" you should have:
/res/layout/layout.xml // Default layout
/res/layout-small/layout.xml // Small screens
/res/layout-large/layout.xml // Large screens
/res/layout-xlarge/layout.xml // Extra large screens
您可以更进一步，让也不同布局纵向和在specyfing另一个关键字目录的景观的意见名称：
You can go even further and make also different layouts for portrait and landscape views by specyfing another keyword in directory's name:
/res/layout-small-land/layout.xml // Small screens, landscape view
/res/layout-small-portrait/layout.xml // Small screens, portrait view
请记住，标签顺序很重要，所以你的不能写布局画像小。
