回答1：

Android的Context类里有常量WINDOW_SERVIC
/** * Use with {@link #getSystemService} to retrieve a * {@link android.view.WindowManager} for accessing the system's window * manager. * * @see #getSystemService * @see android.view.WindowManager */public static final String WINDOW_SERVICE = "window";
所以你可以在activity类里直接调用(ActivityManager) getSystemService(WINDOW_SERVICE)方法，或者得到context得到。
