我遇到了同样的问题，并意识到我在从源检索数据后同时设置了LayoutManager和适配器，而不是在onCreate方法中设置这两个。

salesAdapter = new SalesAdapter(this,ordersList);
        salesView.setLayoutManager(new LinearLayoutManager(getApplicationContext()));
        salesView.setAdapter(salesAdapter);

然后将数据更改通知适配器

               //get the Orders
                Orders orders;
                JSONArray ordersArray = jObj.getJSONArray("orders");
                    for (int i = 0; i < ordersArray.length() ; i++) {
                        JSONObject orderItem = ordersArray.getJSONObject(i);
                        //populate the Order model

                        orders = new Orders(
                                orderItem.getString("order_id"),
                                orderItem.getString("customer"),
                                orderItem.getString("date_added"),
                                orderItem.getString("total"));
                        ordersList.add(i,orders);
                        salesAdapter.notifyDataSetChanged();
                    }

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。

//当你在创建阶段没有设置适配器时发生:当api response得到Its Working时调用notifyDataSetChanged()

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


        magazineAdapter = new MagazineAdapter(getContext(), null, this );
        newClipRecyclerView.setAdapter(magazineAdapter);
        magazineAdapter.notifyDataSetChanged();

       APICall();
}

public void APICall() {
    if(Response.isSuccessfull()){
    mRecyclerView.setAdapter(mAdapter);
   }
}
Just move setting the adapter into onCreate with an empty data and when you have the data call:

mAdapter.notifyDataSetChanged();

ArtistArrayAdapter adapter = new ArtistArrayAdapter(this, artists);
recyclerView = (RecyclerView) findViewById(R.id.cardList);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setAdapter(adapter);

只要用这个替换上面的代码，它就应该工作了。你所做的错误是在调用布局管理器之前调用了setAdapter(适配器)。

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>

这些行必须在OnCreate中:

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