我正在尝试在显示全屏对话框时显示其他菜单,但该菜单不会出现。而是显示一个空白菜单。

我尝试从原始活动中有条件地调用它,并且尝试从对话框视图中调用它。

这是全屏对话框视图:

<androidx.recyclerview.widget.RecyclerView
            android:id="@+id/recyclerView"
            android:layout_width="0dp"  <-- changed this to "match_parrent"
            android:layout_height="0dp"
            android:layout_marginBottom="45dp"
            android:background="@android:color/transparent"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintHeight_default="wrap"
            app:layout_constraintHeight_max="360dp"
            app:layout_constraintHeight_min="60dp"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintRight_toRightOf="parent"
            app:layout_constraintTop_toBottomOf="@id/header"/>

菜单XML

public class MyMainView extends DialogFragment {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setStyle(DialogFragment.STYLE_NORMAL, R.layout.layout_full_screen_dialog);
        setHasOptionsMenu(true);
    }

    @Override public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        menu.clear();
        new MenuInflater(this.getActivity()).inflate(R.menu.add_to_user_library, menu);
        //inflater.inflate(R.menu.add_to_user_library, menu);
        super.onCreateOptionsMenu(menu, inflater);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        super.onCreateView(inflater, container, savedInstanceState);
        View view = inflater.inflate(R.layout.add_to_user_library, container, false);
        // view code here

        return view;
    }
}

从活动

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context=".result.ResultActivity">

    <item
        android:id="@+id/save"
        android:icon="@drawable/ic_check"
        android:showAsAction="ifRoom"
        android:title="@string/menu_save_library"
        tools:ignore="AppCompatResource" />

    <item
        android:id="@+id/go_back"
        android:icon="@drawable/ic_clear"
        android:showAsAction="ifRoom"
        android:title="@string/menu_save_library"
        tools:ignore="AppCompatResource" />
</menu>

现在,当对话框出现但菜单在加载之前就出现了,然后变为空白。

我看到的是以下内容。
