Dialogfragment With Custom Listview

I'm trying to create a DialogFragment that shows a dialog with a custom ListView inside. public class MultiSelectDialogCustom extends DialogFragment { ListView mLocationList;

Solution 1:

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

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

    mLocationList = (ListView)v.findViewById(R.id.location_criteria_list);

    finalFunctionListArrayAdapteradapter=newFunctionListArrayAdapter(
            this, android.R.layout.simple_list_item_1, mOfficeListItems);
    mLocationList.setAdapter(adapter);

    AlertDialog.Builderbuilder=newAlertDialog.Builder(getActivity());

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

    return builder.create();
}

This quote from the DialogFragmentdocumentation 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.

Solution 2:

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."

Solution 3:

what I forgot was:

view.setAdapter(adapter);

after I added that the code worked
