android - 无法单击 fragment ListView 中的项目

Question

我有一个带有抽屉导航 Activity 的项目...有很多带有 ListView 的 fragment 。 ListView 中的项目有(TextView、CheckBox、TextView、ImageView)...

如果我点击整个项目(TextView、CheckBox、TextView、ImageView)我想做一些 Action ，如果我点击 CheckBox 我想做另一个 Action 。

list :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.kubitas.app" >

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".Jidlo"
            android:label="@string/title_activity_jidlo" >

我有这些问题: 我无法点击 ListView 中的项目...(如果我点击项目没有任何反应) 我不知道我是否可以执行其他 2 个操作(一个如果单击整个项目，一个如果我单击 CheckBox)

请问你能帮帮我吗？我试了大约 5 个小时，但什么也没有。

非常感谢，抱歉代码太多。

Answer 1

你可以试试这个:

不要使用

mListView.setOnItemClickListener(this);

在您的 ArrayAdapter 中设置 OnClickListener

在 getView 内部

convertView.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View v) {
      // put your code here                     
   }
});

希望对您有所帮助!
