描述一下，就是我的listview里面有checkbox，我需要在选中item的时候，选中对应的checkbox，这个需求是OK了。

但是发现一个问题，就是我选中第一个，那么第5个，或者第6个（这个取决于每页显示的个数）也会响应，纠结了很久，

问题还是没有得到解决，我贴出来让大家看看

public class PullDownAdapter extends BaseAdapter {

    public interface NumberCallBack {
        void changeNumber(boolean isClick, int position);
    }

    private List<String> itemDatas = null;
    private Context mContext;
    private int select = 999999999;
    private NumberCallBack callBack;

	//记录是否被点击
    public int first[];

    public PullDownAdapter(List<String> itemDatas, Context mContext, NumberCallBack callBack) {
        this.itemDatas = itemDatas;
        this.mContext = mContext;
        this.callBack = callBack;
        first = new int[itemDatas.size()];
        for (int i = 0; i < itemDatas.size(); i++) {
            first[i] = 0;
        }
    }

    @Override
    public int getCount() {
        if (itemDatas != null) {
            return itemDatas.size();
        } else {
            return 0;
        }
    }

    @Override
    public Object getItem(int position) {
        if (itemDatas != null) {
            return itemDatas.get(position);
        } else {
            return 0;
        }
    }

    public void setSelect(int position) {
        this.select = position;
        this.notifyDataSetChanged();
    }

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

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder hold = null;
        if (convertView == null) {
            hold = new ViewHolder();
            convertView = LayoutInflater.from(mContext).inflate(
                    R.layout.item_pull_down, null);
            hold.textView = convertView.findViewById(R.id.tv_pull_down_txt);
            hold.check = convertView.findViewById(R.id.cb_pull_down);
            convertView.setTag(hold);
        } else {
            hold = (ViewHolder) convertView.getTag();
        }
        if (select == position) {
            if (first[position] == 0) {
                hold.check.setChecked(false);
                callBack.changeNumber(false, select);
            } else {
                hold.check.setChecked(true);
                callBack.changeNumber(true, select);
            }
            select = 999999999;
        }

        hold.textView.setText(itemDatas.get(position));
        return convertView;
    }


    class ViewHolder {
        TextView textView;
        CheckBox check;
    }
}



//listview item点击事件
 lvSequences.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                        @Override
                        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                            if (adapter.first[position] == 0) {
                                adapter.first[position] = 1;
                            } else {
                                adapter.first[position] = 0;
                            }
                            adapter.setSelect(position);
                        }
                    });

已经找到了解决的方法，贴出来给大家看一下

 hold.check.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                checkMap.put(position, isChecked);
            }
        });
        if (checkMap.get(position) != null) {
            hold.check.setChecked(checkMap.get(position));
        }

原理就是，定义一个map集合，来保存当前checkbox的状态，然后设置。
