android 图库竖屏不显示status bar

图库在JB和JB2的版本上显示的行为是：横屏全屏显示，竖屏会显示status bar。如何使竖屏也不显示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);
 //        }
    ... 
   }
