public class ScreenShot {

// View是你需要截图的View
View view = activity.getWindow().getDecorView();

// 获取状态栏高度

// 获取屏幕长和高

}
// 保存到sdcard
private static void savePic(Bitmap b, String strFileName) {
FileOutputStream fos = null;

}
// 程序入口
public static void shoot(Activity a) {
ScreenShot.savePic(ScreenShot.takeScreenShot(a), "sdcard/xx.png");
}
}
需要注意的是,shoot方法只能在view已经被加载后方可调用。
或者在 @Override
public void onWindowFocusChanged(boolean hasFocus) {
// TODO Auto-generated method stub
super.onWindowFocusChanged(hasFocus);
ScreenShot.shoot(this);
}中调用
