Android 獲取屏幕尺寸實例代碼

實現(xiàn)代碼：

/** 
 * <supports-screens 
 * android:smallScreens="true" 
 * android:normalScreens="true" 
 * android:largeScreens="true" 
 * android:resizeable="true" 
 * android:anyDensity="true" /> 
 * <uses-sdk android:minSdkVersion="3" android:targetSdkVersion="8" /> 
 * 使Android程序支持了多種分辨率
