Question

修改我意识到问题没有解决，所以我添加了堆栈跟踪。

从活动进行片段事务期间，会发生此错误。我阅读了先前问题的解决方案，但找不到相关案例。事务是通过适配器的回调方法完成的。我是第一次这样做，所以也许有些地方不在。我可以添加相关的回调代码。

最终堆栈跟踪（漆成红色的部分）

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".activities.MainActivity">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:id="@+id/fragments_container">
    </LinearLayout>
</androidx.constraintlayout.widget.ConstraintLayout>

片段的布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="horizontal">

        <Button
            android:id="@+id/button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:text="Button" />

        <Button
            android:id="@+id/button2"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Button" />
    </LinearLayout>
</LinearLayout>

谢谢。

正如您所说的fragments_container处于MainActivity布局，但是您尝试从container类中的activity_list布局调用ListActivity，请尝试像这样更改您的setContentView；

public class ListActivity extends AppCompatActivity implements ListAdapter.ItemClickListener {

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main); // this line

        }
    }

或尝试将fragments_container放在您的activity_list布局中！

尝试一下

public class ListActivity extends AppCompatActivity implements ListAdapter.ItemClickListener {

       FragmentManager fragmentManager;

       @Override
       protected void onCreate(@Nullable Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_list);

       fragmentManager = getSupportFragmentManager();

    }
}

@Override
public void onItemClick(View view, int position) {

    Fragment menuFragment = new MenuFragment();
    FragmentTransaction ft = fragmentManager.beginTransaction(); // FragmentManager
    ft.add(R.id.fragments_container, menuFragment)
            .addToBackStack(null).commit();
  }
}

公共类ListActivity扩展了AppCompatActivity实现的ListAdapter.ItemClickListener {@Override protected void onCreate（@Nullable Bundle savedInstanceState）{super.onCreate（savedInstanceState）; setContentView（R.layout.activity_main）; //此行}} 请致电activity_main代替activity_list

与NavigationComponent一起使用时，视图寻呼机也存在类似问题。问题是，我扩展了FragmentPagerAdapter并使用childFragmentManger对象来创建ViewPager适配器。

我已将FragmentPagerAdapter替换为FragmentStatePagerAdapter，并使用了supportFragmentManager。

我解决了问题.. !!
