java - : java. lang.reflect.InitationTargetException 引起的错误

转载作者：行者123 更新时间：2023-11-30 05:19:22

我正在尝试制作一个简单的内存游戏，目前我只完成了 XML 代码。但由于某些原因我无法理解，在 logcat 中我收到错误由以下原因引起:java.lang.reflect.InitationTargetException在这个java行:setContentView(R.layout.activity_main);。

这行是应用程序在我自动创建它时编写的。

这是我的 XML 代码:

        setContentView(R.layout.activity_main);
    }
}

最佳答案

java.lang.ClassNotFoundException: Didn't find class "android.view.View$OnUnhandledKeyEventListener"

检查this出来，也许有帮助。
