setOnClickListener (новый OnClickListener () не работает во фрагменте

Я работаю над фрагментами навигационного ящика .Andi копирует код действия в фрагменты для выполнения во фрагменте . Я сделал это , макет виден ,но ни одно действие кнопки не работает под действием этого фрагмента.

вы можете сказать мне, что я сделал неправильно ?

FragmentTwo.java
