这些行必须在OnCreate中:

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

只需将代码放入onCreate()方法中

/* Like This*/

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

    recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
    layoutManager = new LinearLayoutManager(YourActivity.this);
    recyclerView.setLayoutManager(layoutManager);
    recyclerView.setHasFixedSize(true);
    mAdapter = new YourAdapter(YourModelClassObject);
    recyclerView.setAdapter(mAdapter);
}

解决方法是在底部设置初始化的空列表和适配器，并在获取结果时调用notifyDataSetChanged。

    LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getContext());
    recyclerviewItems.setLayoutManager(linearLayoutManager);
    someAdapter = new SomeAdapter(getContext(),feedList);
    recyclerviewItems.setAdapter(someAdapter);

//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();

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 {

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();
