工作快一年了，最近用到ListView带复选框功能，虽然已经做过多次了，但对一些初学者还是有一定的困难，在这里顺便总结一下，供大家参考！！！同时希望大家提出意见！！！！

废话不多说，先看效果

效果一:点击全选，所有复选框选中；或每个item分别点击选中会触发全选框选中；

效果二：效果一的状态下，随意取消一个item选中状态，此时全选框改变为不选中

效果三：点击全选框为不选中状态，此时所有item为不选中状态

下面是代码部分：

一、首先是activity_main.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout    xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    tools:context="csttech.com.checkdemo.MainActivity">    <CheckBox        android:id="@+id/ckb_main"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:background="#666666"        android:padding="10dp"        android:text="全选"/>    <ListView        android:id="@+id/list_main"        android:layout_width="match_parent"        android:layout_height="match_parent">    </ListView></LinearLayout>

二、item.xml格式

<?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="match_parent"              android:orientation="vertical">    <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:gravity="center_vertical"        android:orientation="horizontal"        android:padding="10dp">        <TextView            android:id="@+id/text_title"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="1"/>        <CheckBox            android:id="@+id/ckb"            android:focusable="false"            android:focusableInTouchMode="false"            android:clickable="false"            android:layout_width="wrap_content"            android:layout_height="wrap_content"/>    </LinearLayout></LinearLayout>

三、MainActivity.class

package csttech.com.checkdemo;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.util.Log;import android.widget.CheckBox;import android.widget.CompoundButton;import android.widget.ListView;import java.util.ArrayList;import java.util.List;public class MainActivity extends AppCompatActivity {    private ListView mListView;    private List<Model> models;    private CheckBox mMainCkb;    private MyAdapter mMyAdapter;    //监听来源    public boolean mIsFromItem = false;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        initView();        initData();        initViewOper();    }    /**     * view初始化     */    private void initView() {        mListView = (ListView) findViewById(R.id.list_main);        mMainCkb = (CheckBox) findViewById(R.id.ckb_main);    }    /**     * 数据加载     */    private void initData() {        //模拟数据        models = new ArrayList<>();        Model model;        for (int i = 0; i < 15; i++) {            model = new Model();            model.setSt(i + "******");            model.setIscheck(false);            models.add(model);        }    }    /**     * 数据绑定     */    private void initViewOper() {        mMyAdapter = new MyAdapter(models, this, new AllCheckListener() {            @Override            public void onCheckedChanged(boolean b) {                //根据不同的情况对maincheckbox做处理                if (!b && !mMainCkb.isChecked()) {                    return;                } else if (!b && mMainCkb.isChecked()) {                    mIsFromItem = true;                    mMainCkb.setChecked(false);                } else if (b) {                    mIsFromItem = true;                    mMainCkb.setChecked(true);                }            }        });        mListView.setAdapter(mMyAdapter);        //全选的点击监听        mMainCkb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {            @Override            public void onCheckedChanged(CompoundButton compoundButton, boolean b) {                //当监听来源为点击item改变maincbk状态时不在监听改变，防止死循环                if (mIsFromItem) {                    mIsFromItem = false;                    Log.e("mainCheckBox", "此时我不可以触发");                    return;                }                //改变数据                for (Model model : models) {                    model.setIscheck(b);                }                //刷新listview                mMyAdapter.notifyDataSetChanged();            }        });    }    //对item导致maincheckbox改变做监听    interface AllCheckListener {        void onCheckedChanged(boolean b);    }}

四、MyAdapter.class

package csttech.com.checkdemo;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.TextView;import java.util.List;/** * Created by zhaiydong on 2017/1/9. */public class MyAdapter extends BaseAdapter {    private List<Model> data;    private Context context;    private MainActivity.AllCheckListener allCheckListener;    public MyAdapter(List<Model> data, Context context, MainActivity.AllCheckListener allCheckListener) {        this.data = data;        this.context = context;        this.allCheckListener = allCheckListener;    }    @Override    public int getCount() {        return data.size();    }    @Override    public Object getItem(int i) {        return data.get(i);    }    @Override    public long getItemId(int i) {        return i;    }    @Override    public View getView(final int i, View view, ViewGroup viewGroup) {        ViewHoder hd;        if (view == null) {            hd = new ViewHoder();            LayoutInflater layoutInflater = LayoutInflater.from(context);            view = layoutInflater.inflate(R.layout.item_list, null);            hd.textView = (TextView) view.findViewById(R.id.text_title);            hd.checkBox = (CheckBox) view.findViewById(R.id.ckb);            view.setTag(hd);        }        Model mModel = data.get(i);        hd = (ViewHoder) view.getTag();        hd.textView.setText(mModel.getSt());        Log.e("myadapter", mModel.getSt() + "------" + mModel.ischeck());        final ViewHoder hdFinal = hd;        hd.checkBox.setChecked(mModel.ischeck());        view.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                CheckBox checkBox = hdFinal.checkBox;                if (checkBox.isChecked()) {                    checkBox.setChecked(false);                    data.get(i).setIscheck(false);                } else {                    checkBox.setChecked(true);                    data.get(i).setIscheck(true);                }                //监听每个item，若所有checkbox都为选中状态则更改main的全选checkbox状态                for (Model model : data) {                    if (!model.ischeck()) {                        allCheckListener.onCheckedChanged(false);                        return;                    }                }                allCheckListener.onCheckedChanged(true);            }        });        return view;    }    class ViewHoder {        TextView textView;        CheckBox checkBox;    }}

五、Model

package csttech.com.checkdemo;/** * Created by zhaiydong on 2017/1/9. */public class Model {    private boolean ischeck;    private String st;    public boolean ischeck() {        return ischeck;    }    public void setIscheck(boolean ischeck) {        this.ischeck = ischeck;    }    public String getSt() {        return st;    }    public void setSt(String st) {        this.st = st;    }}
