1)创建什么都不做的ViewHolder:)

// SampleHolder.java
public class SampleHolder extends RecyclerView.ViewHolder {
    public SampleHolder(View itemView) {
        super(itemView);
    }
}

2)再次创建RecyclerView，不做任何事情:)

// SampleRecycler.java
public class SampleRecycler extends RecyclerView.Adapter<SampleHolder> {
    @Override
    public SampleHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        return null;
    }

    @Override
    public void onBindViewHolder(SampleHolder holder, int position) {

    }

    @Override
    public int getItemCount() {
        return 0;
    }
}

3)现在，当你真正的回收器还没有准备好时，就使用下面的样品。

RecyclerView myRecycler = (RecyclerView) findViewById(R.id.recycler_id);
myRecycler.setLayoutManager(new LinearLayoutManager(this));
myRecycler.setAdapter(new SampleRecycler());

虽然这不是最好的解决方案，但它确实有效!希望这对你有帮助。

这些行必须在OnCreate中:

mmAdapter = new Adapter(msgList);
mrecyclerView.setAdapter(mmAdapter);

我已经解决了这个错误。你只需要添加布局管理器 并添加空适配器。

像这样的代码:

myRecyclerView.setLayoutManager(...//your layout manager);
        myRecyclerView.setAdapter(new RecyclerView.Adapter() {
            @Override
            public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
                return null;
            }

            @Override
            public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {

            }

            @Override
            public int getItemCount() {
                return 0;
            }
        });
//other code's 
// and for change you can use if(mrecyclerview.getadapter != speacialadapter){
//replice your adapter
//}

只需将以下内容添加到RecyclerView

app:layoutManager="android.support.v7.widget.LinearLayoutManager"

例子:

   <android.support.v7.widget.RecyclerView xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="vertical"
        app:layoutManager="android.support.v7.widget.LinearLayoutManager"
        app:layout_constraintBottom_toTopOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">

    </android.support.v7.widget.RecyclerView>

对于那些在片段中使用RecyclerView并从其他视图中扩展它的人:当扩展整个片段视图时，确保将RecyclerView绑定到它的根视图。

我为适配器正确地连接和做了所有事情，但我从未进行绑定。 @Prateek Agarwal的回答已经为我提供了一切，但这里有更详细的说明。

科特林

    override fun onCreateView(inflater: LayoutInflater?, container: ViewGroup?, savedInstanceState: Bundle?): View? {

    val rootView =  inflater?.inflate(R.layout.fragment_layout, container, false)
    recyclerView = rootView?.findViewById(R.id.recycler_view_id)
    // rest of my stuff
    recyclerView?.setHasFixedSize(true)
    recyclerView?.layoutManager = viewManager
    recyclerView?.adapter = viewAdapter
    // return the root view
    return rootView
}

Java

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

    View rootView= inflater.inflate(R.layout.fragment_layout,container,false);
    recyclerview= rootView.findViewById(R.id.recycler_view_id);
    return rootView;
}
