配套文档：

1. 导入

根目录build添加jitpack

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

添加依赖

dependencies {
    implementation 'com.github.CymChad:BaseRecyclerViewAdapterHelper:3.0.4'
}

2. 使用

1. 编写adapter

/**
 * <pre>
 *     author : i m yours
 *     e-mail : onlyyoulove3@gmail.com
 *     time   : 2020/08/23
 *     desc   : 测试adapter
 *     version: 1.0
 * </pre>
 */
class TestAdapter(var namelist: MutableList<String>) :
    BaseQuickAdapter<String,BaseViewHolder>(R.layout.item_bluetooth,namelist) {

    override fun convert(holder: BaseViewHolder, item: String) {
        holder.setText(R.id.tv_bluetooth_name,item)

    }
    
}

• R.layout.item_bluetooth:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:padding="15dp">

    <View
        android:id="@+id/view"
        android:layout_width="0dp"
        android:layout_height="50dp"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        android:background="@drawable/circle_white"/>

    <TextView
        android:id="@+id/tv_bluetooth_name"
        android:textColor="@color/color_blue_light"
        android:text="bluetooth_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="30dp"
        android:textSize="18sp"
        app:layout_constraintLeft_toLeftOf="@id/view"
        app:layout_constraintTop_toTopOf="@id/view"
        app:layout_constraintBottom_toBottomOf="@id/view"/>

    <TextView
        android:id="@+id/tv_bluetooth_mac"
        android:textColor="@color/color_gray"
        android:text="bluetooth_mac"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginRight="50dp"
        android:textSize="18sp"
        app:layout_constraintRight_toRightOf="@id/view"
        app:layout_constraintTop_toTopOf="@id/view"
        app:layout_constraintBottom_toBottomOf="@id/view"/>

</androidx.constraintlayout.widget.ConstraintLayout>

2. adapter中使用

var namelist: MutableList<String> = arrayOf("笔记本电脑","红米手机","mi8").toMutableList()

var adapter : TestAdapter= TestAdapter(namelist)
rv_bluetooth_list.layoutManager = LinearLayoutManager(this)
rv_bluetooth_list.adapter = adapter

3. 指定点击事件

//item中子项点击事件注册（不要再adapter中注册，具体版本有区别，2.x是在adapter的convert中注册）
adapter.addChildClickViewIds(R.id.tv_bluetooth_name,R.id.tv_bluetooth_mac)
//添加具体item里子项点击事件
adapter.setOnItemChildClickListener { adapter, view, position ->
    Log.d("click","on item child click")
    if (view.id == R.id.tv_bluetooth_name){
        ToastUtil.shortShow("您点击了name:   ${view.id}   这是第{$position}个")
    }else{
        ToastUtil.shortShow("您点击了mac:   ${view.id}   这是第{$position}个")
    }
}

//整个item的点击事件
adapter.setOnItemClickListener { adapter, view, position ->
    ToastUtil.shortShow("this is onitem click : $adapter   $view    $position")
    Log.d("click","on item click")
}

总结

这个库让我印象深刻的原因就是，点击事件实在是太好写了，而且如果是一个List组成的信息需要填充，是非常方便的，只不过每一个版本点击事件的写法都有些不同，具体细节详见上面的GitHub。
