RecyclerView不可见

我的主活动中有这个代码

public class MainActivity extends AppCompatActivity implements MainViewInterface{

RecyclerView rvMovies;

private String TAG = "MainActivity";
MoviesAdapter adapter;
MainPresenter mainPresenter;

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

    setupMVP();
    mainPresenter.getMovies();

    rvMovies = (RecyclerView)findViewById(R.id.rvMovies);

    LinearLayoutManager manager = new LinearLayoutManager(this);
    manager.setOrientation(LinearLayoutManager.VERTICAL);
    rvMovies.setLayoutManager(manager);
    //rvMovies.setHasFixedSize(true);
}

private void setupMVP() {

    mainPresenter = new MainPresenter(this);

}



@Override
public void showToast(String s) {
    Toast.makeText(MainActivity.this,s,Toast.LENGTH_LONG).show();
}

@Override
public void displayMovies(MovieResponse moviesResponse) {

    if(moviesResponse!=null) {
        Log.d(TAG,moviesResponse.getResults().get(1).getTitle());
        adapter = new MoviesAdapter(moviesResponse.getResults(), MainActivity.this);
        rvMovies.setAdapter(adapter);
        adapter.notifyDataSetChanged();
    }else{
        Log.d(TAG,"Movies response null");
    }

}

@Override
public void displayError(String s) {
    showToast(s);
  }
}

但我明白了

E/RecyclerView: No adapter attached; skipping layout

我知道其他人也会问同样的问题。我试过他们的解决办法,但没有成功。我错过了什么?

这是我的适配器代码。

public class MoviesAdapter extends RecyclerView.Adapter<MoviesAdapter.MoviesHolder> {
List<Result> movieList;
Context context;

public MoviesAdapter(List<Result> movieList, Context context){
    this.movieList = movieList;
    this.context = context;
}

@Override
public MoviesHolder onCreateViewHolder( ViewGroup parent, int viewType) {
    View v = LayoutInflater.from(context).inflate(R.layout.row_movies,parent,false);
    MoviesHolder mh = new MoviesHolder(v);
    return mh;
}

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

    holder.tvTitle.setText(movieList.get(position).getTitle());
    holder.tvOverview.setText(movieList.get(position).getOverview());
    holder.tvReleaseDate.setText(movieList.get(position).getReleaseDate());
    Glide.with(context).load("https://image.tmdb.org/t/p/w500/"+movieList.get(position).getPosterPath()).into(holder.ivMovie);

}

@Override
public int getItemCount() {
    return movieList.size();
}

public class MoviesHolder extends RecyclerView.ViewHolder {

    TextView tvTitle,tvOverview,tvReleaseDate;
    ImageView ivMovie;

    public MoviesHolder(View itemView) {
        super(itemView);
        tvTitle = (TextView) itemView.findViewById(R.id.tvTitle);
        tvOverview = (TextView) itemView.findViewById(R.id.tvOverView);
        tvReleaseDate = (TextView) itemView.findViewById(R.id.tvReleaseDate);
        ivMovie = (ImageView) itemView.findViewById(R.id.ivMovie);
    }
  }

谢谢, 西奥。

解决了的

在我的activity_main.xml中,我的身高与0dp相等!!! 我真的不知道这些价值观是怎么体现出来的,是谁体现出来的!!这就是为什么回收站视图不可见的原因!!!
