DialogFragment with custom ListView

Question

I\'m trying to create a DialogFragment that shows a dialog with a custom ListView inside.

public class MultiSelectDialogCustom extends DialogFragment {


            


        

Answer 1

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 the listview refreshes itself with the new set of data found in the adapter."

Answer 2

Instead of using onCreateView you should be overriding onCreateDialog and inside of it, it'll look something like:

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    Collections.addAll(mOfficeListItems, getResources().getStringArray(R.array.offices)); 
    View v = getActivity().getLayoutInflater().inflate(R.layout.fragment_choice_list, null);

    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);

    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

    builder.setTitle(getArguments().getInt("title")).setView(v);

    return builder.create();
}

This quote from the DialogFragment documentation page describes what you're trying to do:

Implementations should override this class and implement onCreateView(LayoutInflater, ViewGroup, Bundle) to supply the content of the dialog. Alternatively, they can override onCreateDialog(Bundle) to create an entirely custom dialog, such as an AlertDialog, with its own content.

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:

view.setAdapter(adapter);

after I added that the code worked
