获取屏幕大小,用于屏幕自适应

Display display =context.getWindowManager().getDefaultDisplay();
screenHeight = display.getHeight();
screenWidth = display.getWidth();

在AndroidManifest.xml进行配置

<supports-screens android:smallScreens="true"
     android:normalScreens="true"
     android:largeScreens="true"
     android:anyDensity="true"/>
<uses-sdk android:minSdkVersion="7" android:maxSdkVersion="8" />
