public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    Context context;
    ArrayList<GsonBean.NewslistBean> list;


    public MyAdapter(Context context, ArrayList<GsonBean.NewslistBean> list) {
        this.context = context;
        this.list = list;
    }


    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        final View view = View.inflate(context, R.layout.xrv_item, null);
        final ViewHolder holder = new ViewHolder(view);
        return holder;
    }


    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        final String picUrl = list.get(position).getPicUrl();
        final Uri uri = Uri.parse(picUrl);
        holder.img.setImageURI(uri);
        holder.tv.setText(list.get(position).getTitle());


    }


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


    class  ViewHolder extends RecyclerView.ViewHolder {


        private final TextView tv;
        private final ImageView img;


        public ViewHolder(View itemView) {
            super(itemView);
            tv = itemView.findViewById(R.id.tv);
            img = itemView.findViewById(R.id.img);
        }
    }
}
