本文介绍了一个在Android系统中通过Launcher的长按事件控制状态栏显示与隐藏的方法。该方法利用了系统属性persist.sys.fullscreen，并修改了PhoneWindowManager和Launcher的源代码。

最近客户有个需求：就是要通过在LANCHER中的长按事件来控制状态栏隐藏和显示，比如说：判断当前的状态栏的状态，如果当前状态栏是隐藏的，那么长按事件就是显示状态栏，如果当前状态栏是显示的，那么长按的事件就是隐藏状态栏。

前面也有一篇文章：ANDROID 动态开关状态栏，是通过广播的形式来动态控制状态栏的，这里有个简单的例子：就是借用LANCHER中长按会弹出选择壁纸的地方来添加我们要实现的功能；下面贴下更改的PATCH
