Adding positive / negative Button to DialogFragment's Dialog

Question

I\'ve already written a DialogFragment. Now I\'ve realized that I want it to have a positive and a negative button just like an AlertDialog. How can I achieve such a thing w

The clearest way.

// Your own onCreate_Dialog_View method
public View onCreateDialogView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    return inflater.inflate(R.layout.your_layout, container); // inflate here
}

@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);

    // do something with 'view'
}

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    // setup dialog: buttons, title etc
    AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(getActivity())
            .setTitle(R.string.dialog_fragment_author_title)
            .setNegativeButton(R.string.dialog_fragment_author_close,
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int whichButton) {
                            dialog.dismiss();
                        }
                    }
            );

    // call default fragment methods and set view for dialog
    View view = onCreateDialogView(getActivity().getLayoutInflater(), null, null);
    onViewCreated(view, null);
    dialogBuilder.setView(view);

    return dialogBuilder.create();
}
