java - 安卓。未分配值

Question

我正在开发一个无法正常工作的 Android 应用程序。应用程序运行，但在最终计算中，未识别每个级别的值。该程序没有向我表明任何错误。我不明白哪里出了问题。

这是 .Java 文件

    }

}

它向我发出警告，表明它没有被使用。

这是 LogCat。因为应用程序无论如何都可以运行。

Answer 1

在 new OnCheckedChangeListener你在那里，它包括一个 @Override您应该使用的方法，而不是您自己的实现；

        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {

        }

尝试移动您的 checkListValues从您的方法到提供的方法的代码。
