public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.ViewHolder>  {
    HotelData[] hoteldata;View view;
    RecyclerAdapter(HotelData[] hoteldata){
        this.hoteldata=hoteldata;
    }
    @Override
    public RecyclerAdapter.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
        View view= LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.recyclerlayout,null);
        ViewHolder viewHolder = new ViewHolder(view);
        return viewHolder;
    }

    @Override
    public void onBindViewHolder(RecyclerAdapter.ViewHolder viewHolder, int i) {
        viewHolder.imageView.setImageResource(hoteldata[i].getImageUrl());
        viewHolder.textView1.setText(hoteldata[i].getHotel());
        viewHolder.textView2.setText(hoteldata[i].getPlace());


    }

    @Override
    public int getItemCount() {
        return hoteldata.length;
    }
    public class ViewHolder extends RecyclerView.ViewHolder{
        TextView textView1,textView2;ImageView imageView;
        public ViewHolder(View itemLayoutView) {
            super(itemLayoutView);
            textView1=(TextView) itemLayoutView.findViewById(R.id.textView1);
            textView2=(TextView) itemLayoutView.findViewById(R.id.textView2);
            imageView=(ImageView) itemLayoutView.findViewById(R.id.imageView1);


        }

    }
}

Answer 1

在您的 RecyclerAdapter 中创建一个 onclicklistener。

 private final OnClickListener mOnClickListener = new MyOnClickListener();

@Override
public MyViewHolder onCreateViewHolder(final ViewGroup parent, final int position) {
    View view= LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.recyclerlayout,null);
    view.setOnClickListener(mOnClickListener);
    return new MyViewHolder(view);
}

点击方法:

@Override
public void onClick(final View view) {
    int itemPosition = mRecyclerView.getChildPosition(view);
    String item = mList.get(itemPosition);//if you want to pass the data 
   //Navigate to your desired activity.
}

这是最简单的方法。
