Android 自定义对话框在一个活动中显示，在另一个活动中未显示，没有错误

我有个小问题。在“我的一个活动”（MainActivity）对话框窗口（dialog_exit）中显示时没有出现任何问题，但在“其他活动”（MenuR）中它（dialog_podaj）没有出现问题。当我点击一个按钮，屏幕就会变暗，仅此而已。没有别的事情发生。没有显示错误。 我认为代码是一样的，但我可能错了。我看不出我的第二个古代密码有任何错误，所以这就是我请求你帮助的原因

这是第一个活动（MainActivity），对话框窗口在此工作：

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();
                }
            });


            MainActButtons();
        }

        private void MainActButtons(){

            button_ng.setOnClickListener(new View.OnClickListener() {

                    startActivity(menu_tryb);
                }
            });

对话框大小是否存在差异？注销对话框-一个小对话框和

对话框\u podaj

是一个全屏对话框吗？所有对话框的大小都差不多，只是普通的对话框。。。。我做过类似的应用程序。并且有相同的代码（我可以说它几乎是复制粘贴的），在这个旧的应用程序中，对话框窗口可以完美地工作。就在那一次活动中，Android Studio不想合作，也不显示对话框窗口。。。我想这是因为指导方针吗？这是我能看到的唯一区别。（对不起我的英语，这不是我的母语…）这不是指导原则错误（我检查了这个）@M.Deer-你能提供你的反馈吗？我希望它对你有用。
