ListView选中后错位问题及解决方案（含单选和多选）

一、单选错位

@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {

<strong>selectPosition = position;</strong>
adapter.notifyDataSetChanged();
}

if (position != selectPosition) {
holder.selItem.setChecked(false);
} else {
holder.selItem.setChecked(true);
}

二、多选错位

package com.qloudfin.jpaybusiness.pos;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.ListAdapter;
import android.widget.TextView;

import com.qloudfin.jpaywallet.R;

public class AddCouponAdapter extends BaseAdapter implements ListAdapter {

private LayoutInflater inflater;
private List<AddCouponBean> list;
final private Map<Integer, Map<String, Object>> maps;
public static ArrayList<String> strList;
public static ArrayList<String> strList1;
private int CheckBtn = -1;

public AddCouponAdapter(Context context, ArrayList<AddCouponBean> list2) {
this.inflater = LayoutInflater.from(context);
this.list = list2;
strList = new ArrayList<String>();
strList1 = new ArrayList<String>();
//为每个item设置初始状态为false</strong>
maps = new HashMap<Integer, Map<String, Object>>();
Map<String, Object> map;
for (int i = 0; i < list.size(); i++) {
map = new HashMap<String, Object>();
map.put("status", false);
maps.put(i, map);</span>
}
}

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

@Override
public Object getItem(int position) {
return null;
}

@Override
public long getItemId(int position) {
return 0;
}

@Override
public View getView(final int position, View convertView, ViewGroup parent) {

final ViewHolder holder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.item_add_coupon, null);
holder = new ViewHolder();
holder.addCouponType = (TextView) convertView
.findViewById(R.id.tv_addcoupon_type);
holder.cb = (CheckBox) convertView.findViewById(R.id.rb_add);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}

AddCouponBean info = list.get(position);
holder.addCouponType.setText(info.getAddCoupon_type());

maps.get(position).put("data", info.getAddCoupon_type());

//设置选择的监听，更新选择状态
holder.cb.setChecked((Boolean) maps.get(position).get("status"));
holder.cb.setOnCheckedChangeListener(new OnCheckedChangeListener() {

@Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
maps.get(position).put("status", isChecked);
if (isChecked) {
strList.add((String) maps.get(position).get("data"));
} else {
strList.remove((String) maps.get(position).get("data"));
}
}
});

return convertView;
}

private class ViewHolder {
public TextView addCouponType;
// public CheckBox rb;
public CheckBox cb;
}
}
