我在使用Base Adapter的列表中使用自定义复选框.
问题是当我单击复选框以取消选中时,其他复选框自动取消选中.
假设我单击0位置的复选框,然后另一个具有第5位置的复选框将自动取消选中.

          public View getView( int position, View convertView, ViewGroup parent) {
    final  ViewHolder  holder = new ViewHolder();
    if (convertView == null) {

        convertView = mInflater.inflate(R.layout.socket_layer, null);
    }
        holder.checkBox = (ImageView) convertView.findViewById(R.id.checkBox_SocketFilter);
        holder.filter_name=(TextView)convertView.findViewById(R.id.filter_name);

        holder.filter_name.setText(rowItems.get(position));
      holder.checkBox.setTag(position);
           holder.onoff.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
         int position = (Integer) v.getTag();
             if(!selectedItems.get(position)){
                 selectedItems.put(position,true);    
                 if(PrefUtils.socketCheck[position].equals(true))
                 {
                         holder.onoff.setImageResource(R.drawable.offf);                         
                     PrefUtils.socketCheck[position]=false;                       
                     selectedItems.delete(position);


                     }
                   else if(PrefUtils.socketCheck[position].equals(false)){
                     holder.onoff.setImageResource(R.drawable.onnn);                  
                     PrefUtils.socketCheck[position]=true;                   
                     selectedItems.delete(position);
                 }
             }else{
             selectedItems.delete(position);
         }
         }
     });
        convertView.setTag(holder);
    }
    else {
        holder = (ViewHolder) convertView.getTag();
    }
