android - Android Listview和Horizo​​ntalview - 如果单击图像，不知道如何获取图像文件名

问题描述

我希望任何Android开发人员都可以帮助我在Horizo​​ntalView List上单击图像时如何获取图像文件名。我尝试将 setOnClickListener tp 添加到 imageview 字段，但它不起作用，并且无法从水平视图列表中滑动而崩溃。

我尝试的是在 中添加以下代码onSingleTapConfirmed，HorizontalListView但它只返回整数值。我想返回我放在 image_image1_array 上的 imageURLHorizontalviewAdapter

public HorizontalviewAdapter(Context Context, int listposition, ItineraryWithPhotos itineraryWithPhotos, ArrayList<String> image1_array )

在 中HorizontalListView，我将以下代码添加到 onSingleTapConfirmed.

Object obj1 = HorizontalListView.this.mAdapter.getItemId(adapterIndex);

下面是我的代码。请帮忙

public class ItineraryListAdapter extends ArrayAdapter<ItineraryWithPhotos> {
    private ItineraryPlanner globalVariable = null;
    private final String sdCardFolderName = "ItineraryPlanner";
    Context context;

    List<ItineraryWithPhotos> itineraryRecordsList;

        this.itineraryRecordsList = itineraryRecordsList;
        inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    @Override

        return itineraryRecordsList.size();
    }

            rowView.setTag(holder);

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

        final ItineraryWithPhotos itineraryWithPhotos = (ItineraryWithPhotos) getItem(position);
        holder.country.setText(itineraryWithPhotos.getCountry());

        HorizontalviewAdapter ada = new HorizontalviewAdapter(context,Listposition, itineraryWithPhotos, itineraryWithPhotos.getPhotoList());
        holder.horizontalListview.setAdapter(ada);

解决方案

在您的代码中，我找到了这种方法：

@Override
public long getItemId(int position) {
    return 0;
}

我认为这个方法应该返回位置，否则它将返回第一项值。
