数据正在三个不同的适配器中被覆盖

Question

我正在尝试将三个不同的数据放入具有相同适配器的三个recyclerView中，并且仅使用一个modelClass，因为放入其中的数据属于同一类型，但是数据被覆盖并且仅显示最后一个数据。我正在使用Picasso库下载并显示图像
这是我的mainActivity.java

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

    recyclerView = (RecyclerView) findViewById(R.id.rcyclvw);
    recyclerView2 = (RecyclerView) findViewById(R.id.rcyclvw2);
    recyclerView3 = (RecyclerView) findViewById(R.id.rcyclvw3);

    mAdapter = new MoviesAdapter(this,movieList);
    RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext(),LinearLayoutManager.HORIZONTAL, false);
    RecyclerView.LayoutManager nLayoutManager = new LinearLayoutManager(getApplicationContext(), LinearLayoutManager.HORIZONTAL, false);
    RecyclerView.LayoutManager oLayoutManager = new LinearLayoutManager(getApplicationContext(), LinearLayoutManager.HORIZONTAL, false);
    recyclerView.setLayoutManager(mLayoutManager);
    recyclerView.setItemAnimator(new DefaultItemAnimator());
    recyclerView.setAdapter(mAdapter);

    nAdapter = new MoviesAdapter(this,batDetails);
    recyclerView2.setLayoutManager(nLayoutManager);
    recyclerView2.setItemAnimator(new DefaultItemAnimator());
    recyclerView2.setAdapter(nAdapter);

    oAdapter = new MoviesAdapter(this,theWoman);
    recyclerView3.setLayoutManager(oLayoutManager);
    recyclerView3.setItemAnimator(new DefaultItemAnimator());
    recyclerView3.setAdapter(oAdapter);

    prepareMovieData();
}

这是我的modelClass.java

public class ModelClass {
private String img, Title, genre;

public ModelClass() {

}

    this.img = img;
    Title = title;
    this.genre = genre;
}

public String getImg() {
    return img;
}

public void setImg(String img) {
    this.img = img;
}

public String getTitle() {
    return Title;
}

public void setTitle(String title) {
    Title = title;
}

public String getGenre() {
    return genre;
}

public void setGenre(String genre) {
    this.genre = genre;
}
}

}

这是我的movie_row_list.xml

感谢Adavance。

无需为每个recylerviews设置值。使其变得常见。

更改

   @Override
public void onBindViewHolder(MoviesAdapter.MyViewHolder holder, int position) {
    ModelClass movie = movieList.get(position);
   ModelClass bat =batDetails.get(position);
    ModelClass womn=theWoman.get(position);
    holder.titl.setText(movie.getTitle());
    holder.titl.setText(bat.getTitle());
    holder.titl.setText(womn.getTitle());
    holder.genr.setText(movie.getGenre());
    holder.genr.setText(bat.getGenre());
    holder.genr.setText(womn.getGenre());
    //holder.year.setText(movie.getYear());
    // holder.imgvw.setImageResource(Picasso.with(context).load(moviesList.get(position).getImg()));
    Picasso.with(context).load(movie.getImg()).into(holder.imgvw);
   Picasso.with(context).load(bat.getImg()).into(holder.imgvw);
    Picasso.with(context).load(womn.getImg()).into(holder.imgvw);
}

收件人

 @Override
public void onBindViewHolder(MoviesAdapter.MyViewHolder holder, int position) {
    ModelClass model = listtr.get(position);

    holder.titl.setText(model.getTitle());     
    holder.genr.setText(model.getGenre());
    //holder.year.setText(model.getYear());
    // holder.imgvw.setImageResource(Picasso.with(context).load(moviesList.get(position).getImg()));
    Picasso.with(context).load(model.getImg()).into(holder.imgvw);   

}

希望有帮助。
