使用带有自定义baseadapter的arraylist错误删除listview项位置

Question

我曾尝试使用arraylist删除listview项，如果单击项的位置，但总是错误地删除了项的位置。为什么删除的项目从底部开始？如果我单击列表视图位置中的任何位置，仍从底部删除。任何机构都可以帮助解决这个问题？

这就是我从数据库中获取数据的方式

                public static ArrayList<Integer> arrIdJob = new ArrayList<Integer>();

                myJSON = json.getJSONArray(TAG_record);
                for (int i = 0; i < myJSON.length(); i++) {
                    JSONObject c = myJSON.getJSONObject(i);

                    arrIdJob.add(Integer.parseInt(c.getString("id_jobpost")));


                }

我正在通过setOnItemClickListener在onCreatView中使用片段

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {

                arrIdJob.remove(i);
                adapterListHome.notifyDataSetChanged();
        }
    });

这是我的适配器扩展BaseAdapter

public class AdapterListHome extends BaseAdapter {



private Activity activity;
private ArrayList<CustomRowClass> listData;
private LayoutInflater layoutInflater;
private Context context;

public AdapterListHome(Context context, ArrayList<CustomRowClass> listData) {
    this.listData = listData;
    layoutInflater = LayoutInflater.from(context);
    this.context = context;
}


public AdapterListHome(Activity act) {
    this.activity = act;
}

public int getCount() {
    return HomeFragment.arrIdJob.size();

}

public Object getItem(int position) {
    return position;
}

public long getItemId(int position) {
    return position;
}

@Override
public int getViewTypeCount() {
    return getCount();
}

@Override
public int getItemViewType(int position) {
    return position;
}

@SuppressLint("SetTextI18n")
public View getView(final int position, View convertView, ViewGroup parent) {

    ViewHolder holder;

    if(convertView == null){
        LayoutInflater inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.desain_view, null);
        holder = new ViewHolder();

        convertView.setTag(holder);

    }else{
        holder = (ViewHolder) convertView.getTag();
    }





    holder.tvJobTitle = (TextView) convertView.findViewById(R.id.tv_jobtitile);
    holder.tvCompanyName = (TextView) convertView.findViewById(R.id.tv_companyname);
    holder.tvState = (TextView) convertView.findViewById(R.id.tv_state);
    holder.tvSalary = (TextView) convertView.findViewById(R.id.tv_minsal);

    //for key
    holder.keyIdUser = (TextView) convertView.findViewById(R.id.key_iduser);
    holder.keyIdJob = (TextView) convertView.findViewById(R.id.key_idjob);
    holder.keyIdCompany = (TextView) convertView.findViewById(R.id.key_idcompany);
    holder.keyQualification = (TextView) convertView.findViewById(R.id.key_qualification);
    holder.keyDesc = (TextView) convertView.findViewById(R.id.key_desc);

    //set
    holder.tvJobTitle.setText(HomeFragment.arrJobTitle.get(position));
    holder.tvCompanyName.setText(HomeFragment.arrCompanyName.get(position));
    holder.tvState.setText(HomeFragment.arrState.get(position));
    holder.tvSalary.setText(toRupiah(HomeFragment.arrMinSal.get(position))+" - "+toRupiah(HomeFragment.arrMaxSal.get(position)));
    //set for key

    holder.keyIdJob.setText(HomeFragment.arrIdJobStr.get(position));
    holder.keyIdCompany.setText(HomeFragment.arrIdCompany.get(position));
    holder.keyQualification.setText(HomeFragment.arrQualification.get(position));
    holder.keyDesc.setText(HomeFragment.arrDesc.get(position));


    //   Picasso.get().load(Config.PATH_URL_IMG_CAT+ ListMenuActivity.IMAGE.get(position)).into(holder.imgThumb);

    return convertView;
}


static class ViewHolder {
    TextView tvJobTitle, tvCompanyName, tvState, tvSalary;
    TextView keyIdUser, keyIdJob, keyIdCompany, keyQualification, keyDesc;
    String data;
    //ImageView imgThumb;
}


private String toRupiah(String nominal){
    String hasil = "";
    DecimalFormat toRupiah = (DecimalFormat) DecimalFormat.getCurrencyInstance();
    DecimalFormatSymbols formatAngka = new DecimalFormatSymbols();
    formatAngka.setCurrencySymbol("Rp. ");
    formatAngka.setMonetaryDecimalSeparator(',');
    toRupiah.setDecimalFormatSymbols(formatAngka);
    hasil = toRupiah.format(Double.valueOf(nominal));
    return hasil;
   }
}

用[替换适配器中的getItem(int position)

public Object getItem(int position) {
    return listData.get(position);
}

此外，请确保您引用的是适配器和ItemClickListener中的相同列表。
