Пользовательский диалог отображался в одном действии, а в другом - нет, ошибок нет.

Question

У меня маленькая проблема. В моем единственном действии (MainActivity) диалоговое окно (dialog_exit) отображается без каких-либо проблем, но в другой интерактивности (MenuR) его (dialog_podaj) нет. Когда я нажимаю кнопку, экран становится темнее, и все. Больше ничего не происходит. Ошибка не отображается. Я думаю, что код тот же, но я могу ошибаться. Я не вижу никакой ошибки во втором коде активности, поэтому я прошу вас о помощи.

Это первое действие (MainActivity), здесь работает диалоговое окно:

public class MainActivity extends AppCompatActivity {

        // [...]
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            setContentView(R.layout.activity_manin);

            mVisible = true;
            mControlsView = findViewById(R.id.fullscreen_content_controlsM);
            mContentView = findViewById(R.id.fullscreen_contentM);



            mContentView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    toggle();
