寫在前面：本文給出Android 13 手機/平板原生SystemUI 一些實用的屏蔽補丁。

1、屏蔽導(dǎo)航欄

??導(dǎo)航欄屏蔽很簡單，直接把創(chuàng)建導(dǎo)航欄的代碼屏蔽即可。

代碼路徑:frameworks\base\packages\SystemUI\src\com\android\systemui\statusbar\phone\CentralSurfacesImpl.java

// ================================================================================

// Constructing the view

// ================================================================================

protected void makeStatusBarView(@Nullable RegisterStatusBarResult result) {

. . . . . .

. . . . . .

. . . . . .

//createNavigationBar(result);//注釋這行代碼即可

. . . . . .

. . . . . .

. . . . . .

}

2、屏蔽鎖屏

3、隱藏狀態(tài)欄

4、禁止狀態(tài)欄下拉

??解鎖之后禁止狀態(tài)欄下拉顯示快捷通知、快捷設(shè)置。

5、屏蔽Camera綠色圖標

??Android 13 使用攝像頭時右上角會有綠色圖標，屏蔽方法如下：

6、屏蔽原生音量條
