AdapterView.OnItemClickListener() 未解雇

Question

我的适配器是这样设置的：

userList = (ListView) activity.findViewById(R.id.userList);
userListAdapter = new UserListAdapter(this, R.layout.user_list, getUserList());
userList.setAdapter(userListAdapter);

function getUserList() return ArrayList UserList

这样列表显示就没问题了

但是当我这样做时：

userList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Log.d("MyTag","kkkkkkkkkkkkkkkkk");
            }
        });

Log.d 未被触发。我查了一下控制台是显示 D/AbsListView: onTouchUp() mTouchMode : 1

我的 Xmls activity_main.xml:

<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/userList"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    tools:context="MainActivity"
    tools:showIn="@layout/activity_main">
</ListView>

user_list.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:padding="10dp"
    android:weightSum="60"
    android:orientation="horizontal">

    <TextView
        android:id="@+id/nom"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="20"/>

    <TextView
        android:id="@+id/type"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="20"/>

    <Button
        android:id="@+id/edit"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="10"
        android:hint="Upd"/>

    <Button
        android:id="@+id/delete"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="10"
        android:hint="Del"/>
</LinearLayout>

在你的适配器中为处理点击事件创建一个接口，如下代码..

onItemClickListner onItemClickListner;

public void setOnItemClickListner(UserAdapter.onItemClickListner onItemClickListner) {
    this.onItemClickListner = onItemClickListner;
}

public interface onItemClickListner{
   public void onItemClick();
}

当任何控件用于单击事件（如孔布局单击事件）时，在适配器中的代码下方使用......在适配器 getView() 方法中

 LinearLayout linearLayout=view.findViewById(R.id.linearLayout);
    linearLayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            onItemClickListner.onItemClick();
        }
    });

当您在列表视图中绑定适配器然后在下面调用之后...

        userListAdapter.setOnItemClickListner(new UserAdapter.onItemClickListner() {
        @Override
        public void onItemClick() {
            Toast.makeText(getApplicationContext(),"Hello world",Toast.LENGTH_SHORT).show();
        }
    });
