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
//}

当你在创建阶段没有设置适配器时，会发生这种情况:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity);
    mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
    ....
}

public void onResume() {
    super.onResume();
    mRecyclerView.setAdapter(mAdapter);
    ....
}

只需移动设置适配器到onCreate与一个空数据，当你有数据调用:

mAdapter.notifyDataSetChanged();

我有和你一样的情况，显示正常，但是定位器出现错误。 这就是我的解决方案: (1)在CREATE()上初始化RecyclerView并绑定适配器

RecyclerView mRecycler = (RecyclerView) this.findViewById(R.id.yourid);
mRecycler.setAdapter(adapter);

(2)当你得到数据时调用notifyDataStateChanged

adapter.notifyDataStateChanged();

在recyclerView的源代码中，有另一个线程来检查数据的状态。

public RecyclerView(Context context, @Nullable AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    this.mObserver = new RecyclerView.RecyclerViewDataObserver(null);
    this.mRecycler = new RecyclerView.Recycler();
    this.mUpdateChildViewsRunnable = new Runnable() {
        public void run() {
            if(RecyclerView.this.mFirstLayoutComplete) {
                if(RecyclerView.this.mDataSetHasChangedAfterLayout) {
                    TraceCompat.beginSection("RV FullInvalidate");
                    RecyclerView.this.dispatchLayout();
                    TraceCompat.endSection();
                } else if(RecyclerView.this.mAdapterHelper.hasPendingUpdates()) {
                    TraceCompat.beginSection("RV PartialInvalidate");
                    RecyclerView.this.eatRequestLayout();
                    RecyclerView.this.mAdapterHelper.preProcess();
                    if(!RecyclerView.this.mLayoutRequestEaten) {
                        RecyclerView.this.rebindUpdatedViewHolders();
                    }

                    RecyclerView.this.resumeRequestLayout(true);
                    TraceCompat.endSection();
                }

            }
        }
    };

在dispatchLayout()中，我们可以发现其中有错误:

void dispatchLayout() {
    if(this.mAdapter == null) {
        Log.e("RecyclerView", "No adapter attached; skipping layout");
    } else if(this.mLayout == null) {
        Log.e("RecyclerView", "No layout manager attached; skipping layout");
    } else {

发生这种情况是因为实际的膨胀布局与您在查找recyclerView时引用的布局不同。默认情况下，当你创建片段时，onCreateView方法如下所示: 返回inflater.inflate(出来。< >相关布局,container.false);

相反，单独创建视图并使用它引用recyclerView 视图视图= inflater. inflation (r.p ayler .layout。< >相关布局,container.false); recyclerview = view.findViewById (R.id。< recyclerView ID >); 返回视图;

在我的情况下，它是一个被遗忘的组件，位于ViewHolder类，但它不在布局文件中

如果你在使用ViewBinding时得到still错误，请确保你使用绑定来返回膨胀的视图

   @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    return fragmentBinding.getRoot();
}
