Prevent back button from closing a dialog box

Question

I am trying to prevent an AlertDialog box from closing when pressing the back button in Android. I have followed both of the popular methods in this thread, and with System.out.

Answer 1

When using DialogFragment you will need to call setCancelable() on the fragment, not the dialog:

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    dialog = new ProgressDialog(getActivity());
    dialog.setIndeterminate(true);
    dialog.setMessage(...);
    setCancelable(false);

    return dialog;
}

Calling dialog.setCancelable() seem to have no effect. It seems that DialogFragment does not takes notice of the dialog's setting for cancelability.
