Java Android应用程序在实现按钮侦听器时崩溃

我希望在选中复选框后更改文本字段的上下文

TextView和Button位于一个片段中

文本视图：

<TextView
            android:text="TextView"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/textView_test" />

听众：

public void onCheckBoxClicked(View view) {
    TextView viewTest = (TextView)findViewById(R.id.textView_test);
    viewTest.setText("test");
}

一旦我选择了一个框，我会得到一个弹出错误，说应用程序不工作。如果侦听器方法没有代码，则选择该框时不会出现任何错误

看起来您导入了错误的TextView类活动（com.rey.material.widget.TextView）

尝试使用导入

android.support.v7.widget.AppCompatTextView

public void onCheckBoxClicked(View view) {
    AppCompatTextView viewTest = (AppCompatTextView)findViewById(R.id.textView_test);
    viewTest.setText("test");
}

请发布错误日志。复选框是否在片段或活动布局中？这是您应该担心的问题-“java.lang.ClassCastException:android.support.v7.widget.AppCompatTextView无法转换为com.rey.material.widget.TextView”。如果您不希望在这里使用自定义TextView类，请检查您的导入并进行相应调整。
