複選框得到檢查，沒有點擊它們

Question

我已經創建了一個應用程序，在其中我檢查了一些複選框，採取他們的values.But每當我檢查單個複選框默認情況下其他一些複選框也得到勾選在list.i不知道什麼是問題，爲什麼它被檢查。 適配器

您使用ViewHolder模式，使同樣的觀點將在此，所以你需要改變你的getView()這樣的代碼被重用..

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

    ViewHolder holder; 
    if (convertView == null) { 
     convertView = mInflater.inflate(R.layout.row, null); 


     holder = new ViewHolder(); 
     holder.name = (TextView) convertView.findViewById(R.id.textView1); 
     holder.number = (TextView) convertView.findViewById(R.id.textView2); 
     holder.chk = (CheckBox) convertView.findViewById(R.id.checkBox1); 
     holder.chk.setTag(position); 
     convertView.setTag(R.layout.row,holder); 
    } else { 
     holder = (ViewHolder) convertView.getTag(R.layout.row); 
    } 
    holder.chk.setOnCheckedChangeListener(null); 
    holder.chk.setChecked(mCheckStates.get(position, false)); 
    holder.chk.setOnCheckedChangeListener(this); 

    ProfileBean bean = filteredData.get(position); 
    holder.name.setText(bean.getName()); 
    holder.number.setText(bean.getNumber()); 
    convertView.setTag(bean); 
    return convertView; 
}
