Create styles. xml under res/values/and set the program style.
　　
<? Xmlversion = "1.0" encoding = "UTF-8"?>
　　
<Resources>
　　
<Stylename = "Transparent">
　　
<Itemname = "android: windowBackground"> @ color/transparent </item>
　　
<Itemname = "android: javaswistranslucent"> true </item>

Android: theme = "@ style/transparent"
　　
If you want to set all the activities to use this style, you can add this label statement to <application>.
