Android Launcher3去除应用列表，二级菜单，应用全部在桌面显示

改动以RK3288 Android 5.1 为例  Launcher3修改方法应该都一样

改动如下：

diff --git a/src/com/android/launcher3/LauncherAppState.java b/src/com/android/launcher3/LauncherAppState.java
index b7c45a34..9d5f221d 100644

去除多余应用   方法比较多，反正我在是编译出来的Out里面删除不要的应用 

参考如下文章删除自己不想要的APP：https://blog.csdn.net/kanyueliang410/article/details/78962288

应用摆放位置布局，device/rockchip/rk3288/overlay/packages/apps/Launcher3/res/xml/default_workspace_5x6.xml

改完后界面如下
