I have an activity which has a fragment. When I click on a list item the current fragment gets replaced with another fragment. This used to work correctly...

However, I would like to move away from SupportFragmentManager to FragmentManager...I will no longer support old android versions.

When I made the switch my app started crashing with the above error. Here is a full stacktrace...

This is the only change that I made and now I am really confused.

Here are they key snippets of code:

Activity:

Fragment2 mFragment2 = new Fragment2();
FragmentTransaction transaction = getFragmentManager().beginTransaction();
transaction.replace(R.id.listFragment1, mFragment2 , FRAGMENT2_FRAGMENT_TAG);
transaction.addToBackStack(null);
transaction.commit();

Fragment2:

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View fragment2= inflater.inflate(R.layout.list_fragment2,
                container, false);

        return fragment2;
    }

XML:

Activity:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/listActivity"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" 
    android:background="@drawable/lists_background"
    android:divider="@color/black">

   <TextView
        android:id="@+id/list_header_text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:textSize="20sp"
        android:textColor="@color/black"
        android:textStyle="bold"/>
   <fragment
        android:id="@+id/listFragment1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/list_header_text"
        android:layout_centerHorizontal="true"
        class="com.test.Fragment1"
        android:tag="Fragment1" />


</RelativeLayout>

Fragment2:

<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:id="@android:id/list"
        android:listSelector="@android:color/transparent"
        android:background="@drawable/lists_background"
        android:divider="@color/black"
        android:dividerHeight="1dip"
        android:clickable="true">
</ListView>

Thank you for your help and let me know if you need more info or details.

将在事务中使用的片段不应放置在 xml 布局中。相反，容器布局应该与添加到该容器的片段一起使用。

为了避免将addView()异常包装ListView在另一个布局中，我不知道为什么会发生这种情况，但似乎框架在重建片段时调用了addView()（未为 的子级实现）方法。AdapterView

为了清楚起见，我也遇到了同样的问题，让我被困了几个小时......

我有一个 Listview 而不是一个 LinearLayout，这给我带来了很多麻烦，

一旦我更换了 LinearLayout 一切都很好

堆栈跟踪告诉您AdapterView存在错误。查看已知的子类，我从您的帖子中看到的唯一一个 AdapterView 就是您的 ListView。确保您没有尝试调用 addView(View) 。
