android 圖庫豎屏不顯示status bar

圖庫在JB和JB2的版本上顯示的行為是：橫屏全屏顯示，豎屏會顯示status bar。如何使豎屏也不顯示status bar。

修改alps/packages/apps/Gallery2/src/com/android/gallery3d/app/AbstractGalleryActivity.java中toggleStatusBarByOrientation() 方法：
 
    private void toggleStatusBarByOrientation() {
        if (mDisableToggleStatusBar) return;
        Window win = getWindow();
        win.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); 
//        if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
//            win.clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
//        } else {
//            win.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
//        }
   ...
   }
