DialogFragment - Get width of dialog

Question

I'm trying to get the width of a DialogFragment on runtime, I've tried two methods which failed.

First: inside onCreateDialog after the dialog has been created

public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    ...
    ...
    AlertDialog dialog =  builder.create();
    width = dialog.getWindow().getAttributes().width;
    return dialog;
}

width was set to -1

Second:

public void onStart() {
    width = getDialog().getWindow().getAttributes().width;
}

width was set to -2

@FaisalAli those methods seem to apply to Activity and not to Fragment objects. — Calc, Apr 05 '14 at 09:14
