我用英语创建了一个应用程序。现在我在res/values-cn的帮助下用阿拉伯语改变了它，它工作正常。现在我想在我的应用程序中实现菜单。我已按照此链接制作自定义菜单。http://www.codeproject.com/Articles/173121/Android-Menus-My-Way#。
它工作正常。并且 MenuItem 的标题也在模拟器中更改为阿拉伯语。但是在手机里找不到解决办法。
我的问题是，如何在 android 设备中更改 MenuItem 的标题。
This is my code which i edited in Demo.java

import android.widget.Toast;
