DialogFragment setCancelable property not working

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.dialog_test, container, true);
    getDialog().requestWindowFeature(STYLE_NO_TITLE);
    getDialog().setCancelable(false);

    return view;
}

instead of getDialog().setCancelable(false); you have to use directly setCancelable(false);

so the updated answer will be like this

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.dialog_test, container, true);
    getDialog().requestWindowFeature(STYLE_NO_TITLE);
    setCancelable(false);

    return view;
}
