android 4.4 设置全屏

 

1,可以通过滑动屏幕来显示status bar：

getWindow().getDecorView()
            .setSystemUiVisibility(
                    View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                            | View.SYSTEM_UI_FLAG_FULLSCREEN
                            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
                            | View.INVISIBLE);

  

2，设置后不能显示status bar.只能重新启动，不过需要在BSP中重新build

getWindow().getDecorView().setSystemUiVisibility( View.STATUS_BAR_DISABLE_EXPAND
				| View.STATUS_BAR_DISABLE_NOTIFICATION_ICONS
				| View.STATUS_BAR_DISABLE_NOTIFICATION_ALERTS
				| View.STATUS_BAR_DISABLE_SYSTEM_INFO | View.STATUS_BAR_DISABLE_HOME
				| View.STATUS_BAR_DISABLE_RECENT | View.STATUS_BAR_DISABLE_BACK);
