MainActivity :
List<IndianMovies> movies=new ArrayList<>();
int posters[]={R.mipmap.avengers,R.mipmap.avengers,R.mipmap.avengers,R.mipmap.avengers,R.mipmap.avengers,R.mipmap.avengers};
String moviename[]={"aaaaa","bbbbbb","ccccc","vvvvvv","eeeeeee","wwwwww"};
String movierate[]={"9.9","5.5","2.3","4.4","5.1","6.2"};
String moviestory[]={"aaaaaaaaaaa","aaaaaaaaa","wwwwwwwwwww","eeeee","rrrrrrr","qqqqq"};
for (int i=0;i<posters.length;i++){
IndianMovies movie=
new IndianMovies(moviename[i],movierate[i],moviestory[i],posters[i]);
movies.add(movie);
}
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
IndianMoviesAdapter adapter = new IndianMoviesAdapter(movies);
recyclerView.setAdapter(adapter);
My Adapter :
public class IndianMoviesAdapter extends RecyclerView.Adapter<IndianMoviesAdapter.IndianMovieHolder>{
List<IndianMovies> moviesList;
public IndianMoviesAdapter(List<IndianMovies> moviesList){
this.moviesList=moviesList;
}
@Override
public IndianMovieHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View row = LayoutInflater.from(parent.getContext()).inflate(R.layout.indian_movie_row,parent,false);
IndianMovieHolder holder = new IndianMovieHolder(row);
return holder;
}
@Override
public void onBindViewHolder(IndianMovieHolder holder, int position) {
IndianMovies movie =moviesList.get(position);
holder.movietitle.setText(movie.moviename);
holder.movierat.setText(movie.movierate);
holder.moviesdesc.setText(movie.moviestory);
holder.poster.setImageResource(movie.posterimage);
}
@Override
public int getItemCount() {
return moviesList.size();
}
class IndianMovieHolder extends RecyclerView.ViewHolder{
TextView movietitle,movierat,moviesdesc;
ImageView poster;
public IndianMovieHolder(View itemView) {
super(itemView);
movietitle =(TextView) itemView.findViewById(R.id.movietitleTV);
movietitle =(TextView) itemView.findViewById(R.id.movieratTV);
moviesdesc =(TextView) itemView.findViewById(R.id.moviedescTV);
poster =(ImageView) itemView.findViewById(R.id.movieposteIMG);
}
}
}
How to fix it ??
