无法解析方法'setupWithNavController(NavController)'

Question

我用 Java 中的流程片段实现了一个单活动架构。我的

MainFlowFragment

是我在此流程中设置底部导航视图的地方，其中包含 4 个片段。

MainFlowFragment.java:

package kz.rating.onaikazakh.presentation.ui.fragments.mainflow;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.appcompat.app.AppCompatActivity;
import androidx.fragment.app.Fragment;
import androidx.navigation.NavController;
import androidx.navigation.NavGraph;
import androidx.navigation.Navigation;
import androidx.navigation.fragment.NavHostFragment;
import androidx.navigation.ui.AppBarConfiguration;
import androidx.navigation.ui.NavigationUI;

import com.google.android.material.bottomnavigation.BottomNavigationView;

import kz.rating.onaikazakh.R;
import kz.rating.onaikazakh.databinding.FlowFragmentMainBinding;

public class MainFlowFragment extends Fragment {

    private NavController navController=null;
    private FlowFragmentMainBinding binding;

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



        return view;
    }

    @Override
    public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        /*Fragment navHostFragment = getChildFragmentManager().findFragmentById(R.id.nav_host_fragment_main);

        navController = Navigation.findNavController(navHostFragment, R.id.nav_host_fragment_main);*/
        BottomNavigationView bnv = view.findViewById(R.id.bottom_navigation);
        NavHostFragment navHostFragment = (NavHostFragment) getChildFragmentManager().findFragmentById(R.id.nav_host_fragment_main);
        navController = navHostFragment.getNavController();
        NavGraph navGraph = navController.getNavInflater().inflate(R.navigation.main_graph);
        /*AppBarConfiguration appBarConfiguration = new AppBarConfiguration.Builder(
                R.id.navigation_grammar, R.id.navigation_texts, R.id.navigation_vocabulary, R.id.navigation_profile)
                .build();
        NavigationUI.setupActionBarWithNavController((AppCompatActivity)getActivity(), navController, appBarConfiguration);
        NavigationUI.setupWithNavController(bnv, navController);*/

        bnv.setupWithNavController(navController);


        navController.setGraph(navGraph);

    }

    @Override
    public void onDestroyView() {
        super.onDestroyView();
    }
}

android.useAndroidX=true

在gradle.properties中设置

我尝试过的：

我看到了这篇文章，并在 onCreateView 和 onViewCreated 中都尝试过。 我尝试将所有依赖项更新为最新版本，以及该主题的其他答案中的版本。 我试过使缓存无效。这些都不起作用。

我还尝试使用 NavigationUI.setupWithNavController(bnv, navController) 进行设置。在这种情况下，它显示了 bottomNavView 和主流，但是没有 fragments 被膨胀。

有人知道怎么解决吗？或者是否有另一种方法将 navController 绑定到 Java 流片段中的 bottomNavView？

更新

感谢 Sohaib Ahmed，它与 NavigationUI.setupWithNavController 一起工作。将块从 Constraint 布局移动到 Frame 布局后，我忘记了更改属性。但是，原来的问题仍然是相关的，所以如果有人知道为什么会出现这个错误，那将是有益的。

Answer 1

把你的身高改成

match_parent

<androidx.fragment.app.FragmentContainerView
    android:id="@+id/nav_host_fragment_main"
    android:name="androidx.navigation.fragment.NavHostFragment"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    app:defaultNavHost="true"
    app:navGraph="@navigation/main_graph" />

到

android:layout_height="match_parent"
