This article mainly introduces the Android imitation WeChat menu (Menu) (implemented using C# and Java respectively). This article gives the operating effects and implementation code of the C# and Java versions respectively. Friends in need can refer to the following

This article uses programming to implement Android menus. Of course, you can use XML to complete the same function. The basic Java and C# writing methods are the same, so using XML to demonstrate using Java in this article requires attention. Yes, if it is not developed by VS, the resource file name must start with lowercase, otherwise an error will be reported.
