java - 过滤 ListView 后位置错误

Question

我的问题是，当我使用baseadapter过滤 ListView 时，我得到了完美的结果，但是单击此项目后，我无法获取该项目的相关值，但我得到了错误的位置项目，因此notifydataset Chenged不起作用。

'public ConsultationAdpater(Context context, ArrayList<Doctor> doctors) {
    this.context = context;
    this.doctorList = doctors;
    this.mStringFilterList = doctors;
    getFilter();
    imageLoader = ImageLoader.getInstance();
    this.inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    // set options for image display
    options = new DisplayImageOptions.Builder()
            .showImageOnLoading(R.drawable.activity_indicator)
            .showImageForEmptyUri(R.drawable.image_not_available)
            .showImageOnFail(R.drawable.image_not_available)
            .resetViewBeforeLoading(true).cacheInMemory(true)
            .cacheOnDisk(true).considerExifParams(true)
            .bitmapConfig(Bitmap.Config.RGB_565).build();

}

@Override
public int getCount() {
    return doctorList.size();
}

@Override
public Object getItem(int position) {
    return doctorList.get(position);
}

@Override

    return position;

@Override

        holder = new ViewHolder();
        holder.image = (ImageView) convertView
                .findViewById(R.id.img_row_const);
        holder.txtName = (TextView) convertView
                .findViewById(R.id.tDtNm_row_const);
        holder.txtSpeciality = (TextView) convertView

    if (images[position] == null) {
        holder.image.setImageResource(R.drawable.image_not_available);
    } else {
        imageLoader.displayImage(
                "http://37.252.121.94/" + images[position], holder.image,
                options);

    }

    return convertView;
}

这对我有用

mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, final View view, int position, long id) {
        //abrirActividadDetallada(position, id);
        Object MyObject=(Object) parent.getAdapter().getItem(position);
        CustomMethod(MyObject);
    }
});
