ListView CheckBox 全选，单选

最近做商城项目，在购物车模块有用到listView 和checkBox单选全选，所以在这里记录一下，和大家共勉。如果有不对的地方请多多指教 ，多多包含。话不多说上代码。

activity代码
/**
* @类说明 listView checkBox的单选 全选删除 适用于商城购物车模块
*
*/

适配器代码

public class SelectBoxAdapter extends BaseAdapter {    private Activity mContext;    private LayoutInflater inflater;    private List<Map> mList;    // 是否编辑完成    private boolean isEditState = true;    public SelectBoxAdapter(Activity context,List<Map> list) {        this.mContext = context;        this.mList = list;        inflater = LayoutInflater.from(mContext);    }     /**     * 切换 "编辑" "完成" 状态     */    public void setEditState(boolean editState) {        this.isEditState = editState;    }    public boolean getEditState() {        return isEditState;    }    @Override    public int getCount() {        return mList.size();    }    @Override    public Object getItem(int position) {        return mList.get(position);    }    @Override    public long getItemId(int position) {        return position;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        ViewHolder mHolder = null;        Map item = mList.get(position);        if(convertView == null){            mHolder = new ViewHolder();            convertView = inflater.inflate(R.layout.item_checkbox, null);            mHolder.check_select = (CheckBox)convertView.findViewById(R.id.check_select);            mHolder.txt_select = (TextView)convertView.findViewById(R.id.txt_select);            convertView.setTag(mHolder);        }else {            mHolder = (ViewHolder)convertView.getTag();        }        mHolder.txt_select.setText(item.get("content").toString());        mHolder.check_select.setChecked(item.get("flag").equals("true"));        mHolder.check_select.setVisibility(isEditState ?

代码其实挺简单的，在这里主要是想记录一下。完整的项目在我的qq群里面有，有想要源码的可以加我的技术群 174905615。大家一起交流学习，谢谢。
