Java 碎片内的按钮赢得'；即使没有错误也不能工作

我在碎片里的按钮坏了。没有错误，我也不知道它出了什么问题

首先初始化它

Button btnCalculate = (Button) rootView.findViewById(R.id.value);
btnCalculate.setOnClickListener( now ur function)

尝试检查您是否收到此消息

btnCalculate.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
    Toast.makeText(view.getContext(), "Onclick Listeber button calculate", Toast.LENGTH_LONG).show();

在何处以及如何初始化btnCalculate？btnCalculate=（按钮）rootView.findViewById（R.id.btnCalculate）；我在最终视图rootView=inflater.inflate（R.layout.genapp，container，false）之后立即初始化它。谢谢！如果它不太长，您能发布完整的onCreateView代码（或简化版本）还有您的xml布局？是否有任何布局可能会阻止单击事件？我已经在最终视图根视图行之后初始化了按钮。我应该在onClick中再次初始化它吗？谢谢！不，如果您已经初始化它，那么您不需要再次初始化它。除了初始化之外，我还遗漏了任何代码n？谢谢！这意味着您的单击事件正在工作，很可能是逻辑出了问题，无法生成您期望的输出。我的建议：尝试使用断点调试您的程序。非常感谢您的帮助：）@jmjarkas将标题更改为“已解决”，这样其他人就不会再浪费时间，如果答案解决了您的问题，就接受它。还有一件事，您应该尽可能少地使用应用程序上下文。如果活动上下文不可靠，则使用它。
