【中文标题】当 RadioButton 单击 Listview 时 setOnItemClickListener 不起作用

【英文标题】：When RadioButton clicked Listview setOnItemClickListener does not work

【发布时间】：2018-04-10 17:39:07

【问题描述】：

当我单击radioButton 时，Listview 的onClickListener 不会响应操作。需要做什么才能采取行动。当我在 Listview 上单击 radioButton 时，我想采取行动。但是其他组件在点击时会被listviewListener 监听。有类似的问题，但我找不到解决此问题的正确答案。

它只包含列表视图代码。 activity_question.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_
    android:layout_
    android:orientation="vertical">

    <ListView
        android:id="@+id/activityQuestionList"
        android:layout_
        android:layout_
        android:divider="@color/gray"
        android:dividerHeight="@dimen/listview_divider_height" />

</LinearLayout>

java 代码。

activityQuestionList = (ListView) findViewById(R.id.activityQuestionList);
        activityQuestionList.setItemsCanFocus(false);

        questionAdapter = new QuestionAdapter(questions, this);
        activityQuestionList.setAdapter(questionAdapter);


        activityQuestionList.setOnItemClickListener(new AdapterView.OnItemClickListener() 
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) 
                switch (view.getId()) 
                    case R.id.answerRadio1:
                        answerA(i);
                        Toast.makeText(view.getContext(), "index : " + i, Toast.LENGTH_SHORT).show();
                        break;
                    case R.id.answerRadio2:
                        answerB(i);
                        break;
                    case R.id.answerRadio3:
                        answerC(i);
                        break;
                    case R.id.answerRadio4:
                        answerD(i);
                        break;
                

                Toast.makeText(view.getContext(), "index : " + i, Toast.LENGTH_SHORT).show();
            
        );

【问题讨论】：

问题结构？

我有列表视图。当我点击 textview 组件时，响应 onClickItemListener。但是当我点击单选按钮时，我无法在 onClickItemListener 上收听它。

【参考方案1】：

实现 setOnCheckedChangeListener 方法

private void checkListeners() 
    radioButton1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() 
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) 
            if(isChecked)
                condition1=1;
            else
                condition1=0;
        
    );

    radioButton2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() 
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) 
            if(isChecked)
                condition2=1;
            else condition2=0;
        
    );
