Question

我已经使用baseAdepter显示三个View in list。前两个是textView，最后一个是checkBox View。但是，当我要检查checkBox并滚动列表时，在某个特定数量的项目之后，另一个复选框会自动检查，无法使用..

我不知道为什么会发生这种事情。

是否有人知道解决方案..

这是我的baseadepter代码..

private static class AdepterGetUnit extends BaseAdapter{
private LayoutInflater mInflater;

public AdepterGetUnit (Context context){
   mInflater = LayoutInflater.from(context);
}
@Override
public int getCount() {

    positionList  = sharedPreferences.getInt(UnitScreen.POSITION, 0);           

    if(positionList==0){currentListLenght=ArrayHolder.dbSpeed.size();}
    else if(positionList==1){currentListLenght=ArrayHolder.dbAngle.size();}
    else if(positionList==2){currentListLenght=listTemperature.length;}
    else if(positionList==3){currentListLenght=ArrayHolder.dbLenght.size();}
    else if(positionList==4){currentListLenght=ArrayHolder.dbWeightMass.size();}
    else if(positionList==5){currentListLenght=ArrayHolder.dbPressure.size();}
    else if(positionList==6){currentListLenght=ArrayHolder.dbPower.size();}
    else if(positionList==7){currentListLenght=ArrayHolder.dbCurrency.size();}
    else if(positionList==8){currentListLenght=ArrayHolder.dbDataSize.size();}
    else if(positionList==9){currentListLenght=ArrayHolder.dbVolume.size();}
    else if(positionList==10){currentListLenght=ArrayHolder.dbTime.size();}
    else if(positionList==11){currentListLenght=ArrayHolder.dbArea.size();}
    else if(positionList==12){currentListLenght=ArrayHolder.dbCoocking.size();}
    return  currentListLenght;
 }

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder holder;
       if (convertView==null){
           convertView = mInflater.inflate(R.layout.row_edit_unit, null);

尝试以下代码。你的答案是对的，我刚编辑过。

android带有baseAdapter的checkBox问题
