How to refresh Child List within Expandable List View
I am using following code to delete child list item, but unable to refresh Child Item List.
public class ListAdapter extends BaseExpandableListAdapter {
private Context _context;
private List<String> _listDataHeader;
private HashMap<String, List<String>> _listDataChild;
private DBAdapter mydb;
public SyncExpandablePendingListAdapter(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
public View getChildView(final int groupPosition, final int childPosition,
boolean isLastChild, View convertView, ViewGroup parent) {
....
if (convertView == null) {
LayoutInflater infalInflater = (LayoutInflater) this._context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = infalInflater.inflate(R.layout.sync_pending_list_item, null);
}
....
btnDelete.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Log.d("oldList:", _listDataChild.toString());
mydb.DeleteECRecord(data2);
_listDataChild.remove(childPosition);
notifyDataSetChanged();
Log.d("newList:", _listDataChild.toString());
});
}
.............
}
Actually, I am not getting where I have to make the change ? What exactly I have missed ? :
Please let me know Where I am doing MISTAKE ? What I am MISSING ?
You removed that entry from your database, but didn't remove it from the HashMap. Remove it from HashMap too and then call notifyDataSetChanged().
