Question

我已记录group position和child position的值但即使我点击不同的项目，它也会在日志中显示相同的childposition。

我为不同的group Position获得了不同的价值，但child position的价值却不同。

我想将所选的子位置传递给下一个活动，以便我可以调用api并存储该特定位置的值。

public class ExpandableListAdapter extends BaseExpandableListAdapter {

private Context _context;
private List<String> _listDataHeader; // header titles

private HashMap<String, List<String>> _listDataChild;
private LinearLayout timming, services, managediscount, editlocation;

public ExpandableListAdapter(Context context, List<String> listDataHeader, HashMap<String, List<String>> listChildData) {
    this._context = context;
    this._listDataHeader = listDataHeader;
    this._listDataChild = listChildData;
}

@Override
public Object getChild(int groupPosition, int childPosititon) {
    return this._listDataChild.get(this._listDataHeader.get(groupPosition)).get(childPosititon);
}

@Override
public long getChildId(int groupPosition, int childPosition) {
    return childPosition;
}

@Override

        convertView = infalInflater.inflate(R.layout.list_item, null);
