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();

感谢Adavance。
答案 0 :(得分：0)
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);
}

@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。
