I'm trying to create a DialogFragment that shows a dialog with a custom ListView inside.
public class MultiSelectDialogCustom extends DialogFragment {
ListView mLocationList;
private ArrayList<String> mOfficeListItems = new ArrayList<String>();
public static MultiSelectDialogCustom newInstance(int title) {
MultiSelectDialogCustom dialog = new MultiSelectDialogCustom();
Bundle args = new Bundle();
args.putInt("title", title);
dialog.setArguments(args);
return dialog;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
Collections.addAll(mOfficeListItems, getResources().getStringArray(R.array.offices));
View v = inflater.inflate(R.layout.fragment_choice_list, container,
true);
mLocationList = (ListView)v.findViewById(R.id.location_criteria_list);
final FunctionListArrayAdapter adapter = new FunctionListArrayAdapter(
this, android.R.layout.simple_list_item_1, mOfficeListItems);
mLocationList.setAdapter(adapter);
getDialog().setTitle(getArguments().getInt("title"));
return v;
}
}
When calling it from a fragment :
MultiSelectDialogCustom dialogFrag = MultiSelectDialogCustom_.newInstance(R.string.dialog_title);
dialogFrag.show(getActivity().getSupportFragmentManager(), null);
It only shows a blank dialog with the title... why my isn't my list displayed?
Instead of using
onCreateView
you should be overridingonCreateDialog
and inside of it, it'll look something like:This quote from the
DialogFragment
documentation page describes what you're trying to do:In your case, it seems like
onCreateDialog
is the way to go since you want to do a custom inner view.what I forgot was:
after I added that the code worked
May be you are missing something very small but important. Are you missing
notifyDataSetChanged()
in your adapter?"Once you have added the new item to the adapter you have to call
notifyDataSetChanged()
so that thelistview
refreshes itself with the new set of data found in the adapter."
