ListView中CheckBox复用问题

本人第一次写博客，希望各位看官不要笑话，这里介绍了一个ListView中CheckBox复用问题的解决方案，如本人代码表写有问题，希望各位可以及时指正哦，谢谢~

首先是MainActivity中的代码

public class MainActivity
        extends AppCompatActivity
{

    private ListView mLv;
    List mDatas;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initView();
        initdata();
        //设置adapter
        mLv.setAdapter(new LvAdapter(this,mDatas));

    }

    private void initdata() {
        mDatas = new ArrayList();
        for (int i=0;i<100;i++){
            mDatas.add(i);
        }
    }

    private void initView() {
        mLv = (ListView) findViewById(R.id.lv);
    }
}

MainActivity中布局

xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    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"
    tools:context="com.example.com.checkboxlistview.MainActivity">

    <ListView
        android:id="@+id/lv"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />
RelativeLayout>

Adapter中的代码

public class LvAdapter
        extends BaseAdapter
{
    private static final String TAG = "LvAdapter";
    private final Context mContext;
    private final List mDatas;
    ArrayList list;

    public LvAdapter(Context context, List datas) {
        mContext = context;
        mDatas = datas;
        //创建一个list去保存bean,bean里面保存了CheckBox的状态
        list = new ArrayList();
    }

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

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        final ViewHolder holder;
        if(convertView == null){
            convertView = LayoutInflater.from(mContext).inflate(R.layout.item_lv,null);
            holder = new ViewHolder();
            holder.cb = (CheckBox) convertView.findViewById(R.id.cb);
            holder.tv = (TextView) convertView.findViewById(R.id.tv);
            convertView.setTag(holder);
        }else{
            holder = (ViewHolder)convertView.getTag();
        }

        holder.tv.setText(mDatas.get(position) + "");

        //创建出来的bean，根据每个position保存了每个position里面的checkBox的状态
        Bean bean = new Bean();
        list.add(bean);

        // 解决CheckBox的复用问题
        holder.cb.setOnClickListener(new View.OnClickListener() {// 设置checkBox点击事件
            @Override
            public void onClick(View v) {
                // 判断checkBox的勾选状态，并保存到bean中
                if (holder.cb.isChecked()) {
                    // 手动保存每个checkBox的勾选状态
                    list.get(position).setCheck(true);
                } else {
                    // 手动保存每个checkBox的勾选状态
                    list.get(position).setCheck(false);
                }
            }
        });
        Bean states = list.get(position);
        // 重新取出checkBox的勾选状态并设置
        holder.cb.setChecked(states.isCheck());

        return convertView;
    }

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

    @Override
    public long getItemId(int position) {
        return position;
    }

    class ViewHolder{
        CheckBox cb;
        TextView tv;
    }
}

ListView中item的布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="horizontal"
              android:layout_width="match_parent"
              android:layout_height="match_parent">

    <CheckBox
        android:id="@+id/cb"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

    <TextView
        android:id="@+id/tv"
        android:layout_marginLeft="15dp"
        android:gravity="center"
        android:textSize="18sp"
        android:textColor="#ff0000"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="11"/>

LinearLayout>

用来保存CheckBox状态的bean

public class Bean {
    private static final String TAG = "Bean";
    private boolean checked;

    public boolean isCheck() {
        return checked;
    }

    public void setCheck(boolean checked) {
        this.checked = checked;
    }
}
