推荐答案

您必须编写XML code大屏幕。我想您把XML文件在res /布局文件夹中。如果它是你可以保持三个文件夹，以区分不同的屏幕像RES /布局小，RES /布局，RES /布局长。在这三个文件夹，你可以设置不同的alignements不同类型的屏幕。对于中型屏幕，让你的XML code布局，并为小屏幕 - 保持在布局小等，并设置

You have to write xml code for large screen. I think you are keeping your xml file in res/layout folder. if it is you can keep three folders to differentiate various screens like res/layout-small, res/layout, res/layout-long. In these three folders you can set different alignements to various screen types. For Medium Screen, keep your xml code in layout, and for small screens - keep it in layout-small and etc., and set

    <supports-screens
    android:smallScreens="true"
    android:normalScreens="true"
    android:largeScreens="true"        
    android:anyDensity="true" />

这些线在你的Andr​​oidManifest.xml

these lines in your AndroidManifest.xml
