Java 从McClick中弹出菜单

java android menu

Java 从McClick中弹出菜单,java,android,menu,Java,Android,Menu,我正试着从McClick中为菜单充气。我查看了android开发者网站，并使用下面的第一个代码为大家祝酒。然而，当我试图用菜单充气器代替它时，它不起作用。你能帮我解决这个问题吗？第一组代码是可以工作的烤面包片充气机，第二组代码是不能工作的菜单充气机。当我点击一个项目时，会弹出祝酒词，但菜单不会。程序将不运行，并说我在菜单充气器中有多个语法错误。虽然我不能解决它们 package com.carouseldemo.main; import com.carouseldemo.controls.Ca

这是正确的。但是，当我尝试膨胀菜单而不是烤面包时，它不会。这是不起作用的代码，并且菜单膨胀器中存在语法错误。无论我尝试做什么，我都无法更正代码
