ListViewAdapter

在build.gradle中导入配置

compile 'com.github.CymChad:BaseRecyclerViewAdapterHelper:2.9.30'

package com.ahtelit.zbv.myapplication;

import java.util.ArrayList;
import java.util.List;

import android.content.Context;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.ImageView;
import android.widget.TextView;

public class LVAdapter_Two extends BaseAdapter {

    private List<LVItem> datas;
    private Context mContext;

    public LVAdapter_Two(Context context,ArrayList<LVItem> list){
        datas=list;
        mContext=context;
    }

    @Override
    public int getCount() {
        return datas.size();
    }

    @Override
    public Object getItem(int position) {
        return datas.get(position);
    }

    @Override
    public long getItemId(int position) {

    }

    private ViewHolder mViewHolder=null;

            mViewHolder=new ViewHolder();
            //加载布局初始化item组件

            mViewHolder.iv_img=(ImageView) convertView.findViewById(R.id.item_img);
            mViewHolder.tv_txt=(TextView) convertView.findViewById(R.id.item_tv_txt);
            mViewHolder.tv_date=(TextView) convertView.findViewById(R.id.item_tv_date);
            mViewHolder.cb_sel=(CheckBox) convertView.findViewById(R.id.item_cb);
            convertView.setTag(mViewHolder);
        }else{

        mViewHolder.tv_date.setText(datas.get(position).getDate());

//        mViewHolder.cb_sel.setChecked(datas.get(position).isSelected());

        /*
        mViewHolder.cb_sel.setChecked(datas.get(position).isSelected());在监听器前面
        例如可见是7，当第一个被选中，到第八个复用第一个这时第八个是非选中状态，要触发checkedChange监听
        而此时clickPosition=0,就把第一个的选中状态给取消了，这是因为这个check的监听器还是第一个控件的监听器，
        当先执行setcheck时就会出现clickPosition=0
        mViewHolder.cb_sel.setChecked(datas.get(position).isSelected());在监听器后面
        第八个复用第一个控件时clickPosition=8,控件一的状态还是选中状态
         */
        mViewHolder.cb_sel.setOnCheckedChangeListener(new OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

                Log.d("zbv","click position="+position);
                datas.get(position).setSelected(isChecked);
//                datas.get(position).setSelected(isChecked);
                //这句代码有问题---因为当前的viewHolder
//                mViewHolder.cb_sel.setChecked(isChecked);
            }
        });

        mViewHolder.cb_sel.setChecked(datas.get(position).isSelected());

        Log.d("zbv","first state="+datas.get(position).isSelected());

        return convertView;
    }

    private static class ViewHolder{

        TextView tv_txt;
        TextView tv_date;

使用BaseRecyclerViewAdapterHelper

package com.ahtelit.zbv.myapplication.TestBaseRV;

import android.support.annotation.Nullable;
import android.util.Log;
import android.widget.CheckBox;
import android.widget.CompoundButton;

import com.ahtelit.zbv.myapplication.LVItem;
import com.ahtelit.zbv.myapplication.R;
import com.chad.library.adapter.base.BaseQuickAdapter;
import com.chad.library.adapter.base.BaseViewHolder;

import java.util.List;

/**
 * Created by Administrator on 2018/5/22.
 * qzx
 */

public class TestAdapter extends BaseQuickAdapter<LVItem,BaseViewHolder> {
    public TestAdapter(int layoutResId, @Nullable List<LVItem> data) {
        super(layoutResId, data);
    }

    @Override
    protected void convert(BaseViewHolder helper, final LVItem item) {

        helper.setIsRecyclable(false);
        helper.setImageResource(R.id.item_img,item.getResId_img());
        helper.setText(R.id.item_tv_txt,item.getText());
        helper.setText(R.id.item_tv_date,item.getDate());
        final CheckBox checkBox=(CheckBox) helper.getView(R.id.item_cb);

        checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

                item.setSelected(isChecked);
            }
        });

        checkBox.setChecked(item.isSelected());


    }
}

Item的Layout

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <ImageView 
        android:id="@+id/item_img"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@mipmap/ic_launcher"
        />

    <TextView 
        android:layout_toRightOf="@+id/item_img"
        android:id="@+id/item_tv_txt"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="七子笑"
        />

    <TextView 
        android:layout_toRightOf="@+id/item_img"
        android:layout_below="@+id/item_tv_txt"
        android:layout_alignBottom="@+id/item_img"
        android:gravity="bottom"
        android:id="@+id/item_tv_date"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="2018/05/02"
        />

    <CheckBox 
        android:id="@+id/item_cb"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_centerVertical="true"
        />

</RelativeLayout>
