Question

我需要将片段添加到recyclerView项目有什么办法吗？我试图为recyclerview设置适配器，但我得到了自爆错误我不知道是否可以这样做或者我需要使用getFragmentManager在代码中添加片段

这是我的list_item.xml

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


    <fragment xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/mFragment"
        android:name="com.ma.myFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:layout="@layout/fragment_layout" />


</LinearLayout>

这里是我的oncreateholder方法

@Override
public ListAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    context = parent.getContext();
    View view = LayoutInflater.from(context).inflate(R.layout.list_item, parent,true);

    return new ViewHolder(view);
}

这是错误

你想要的东西不会成功。 RecyclerView并不意味着在其子视图中包含片段。回收站视图中的视图将被回收，但您不能简单地回收碎片。

您可以尝试使用onBindViewHolder中的片段管理器动态替换子视图中的片段。但即使它有效，它也不是一个好的解决方案。

为什么你需要在回收站视图中使用片段？

我可以将片段添加到list_item.xml以在Recycle View中使用
