android - 如何将详细信息从 Recycler View 传递到另一个 Activity ？

Question

public class RVAdapter extends
    RecyclerView.Adapter<RVAdapter.PersonViewHolder> {    public
    List<Person> persons= Collections.emptyList(); //    private Context
    mContext; private LayoutInflater inflater;
    
    
    
        ImageLoader mImageLoader = AppController.getInstance().getImageLoader();
    
        private static Context context;
    
    
        public RVAdapter(Context context, List<Person> persons) {
            this.persons = persons;
              this.context = context;
            inflater = LayoutInflater.from(context);
        }
    
        @Override
        public PersonViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
            View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.cardview,
    parent, false);
            PersonViewHolder pvh = new PersonViewHolder(v);
    
    
            return pvh;
        }
    
        @Override
        public void onBindViewHolder(PersonViewHolder holder, int postions) {
    
            Person person = persons.get(postions);
            holder.phoneName.setText(person.getKitchen_accesries());
            holder.phonePrice.setText(person.getKitchen_price());
            holder.itemView.setTag(person);
    
       if (mImageLoader == null)
               mImageLoader = AppController.getInstance().getImageLoader();
          holder.thumbnail.setImageUrl(person.getThumbnail(), mImageLoader);
    
    
        }
    
    
        @Override
        public int getItemCount() {
            if (persons != null) {
                return persons.size();
            }
            return 0;
        }
    
    
        @Override
        public void onAttachedToRecyclerView(RecyclerView recyclerView) {
            super.onAttachedToRecyclerView(recyclerView);
        }
    
        public static class PersonViewHolder extends RecyclerView .ViewHolder
                implements View
                .OnClickListener  {
            CardView cv;
            TextView phoneName;
            TextView phonePrice;
            public List<Person> persons;
    
    
            NetworkImageView thumbnail;
    
            PersonViewHolder(View itemView) {
                super(itemView);
    
                cv = (CardView) itemView.findViewById(R.id.card_view);
                phoneName = (TextView) itemView.findViewById(R.id.phone_name);
                phonePrice = (TextView) itemView.findViewById(R.id.phone_price);
                thumbnail = (NetworkImageView) itemView.findViewById(R.id.thumbnail);
                itemView.setOnClickListener(this); //
            }
    
            @Override
            public void onClick(View view ) {
    
    
    
                Intent intent = new Intent(context,ViewActivity.class);
    
                context.startActivity(intent);
    
            }
    
    
        }
    
    
    }

一旦我触摸 recyclerview 上的项目，它就会转到 Viewactivity 类，但我无法将列表中的详细信息传递给 detailsactivity 类。我想使用 put extra 将我的 Web 服务中的三个详细信息传递到 View Activity 。但是在 Onclick 方法中我没有从列表中获得项目的确切位置。

Answer 1

在你的onclick中添加以下内容

Person person =(Person)view.getTag();
String strUrl= person.getThumbnail();
String product1=person.getKitchen_accesries();
intent.putExtra("Your string key",strUrl);
intent.putExtra("Your string key",product1);
intent.putExtra("Your string key",product1);
context.startActivity(intent);

然后访问您的详细信息 Activity 中的所有内容

phone=(TextView)findViewById(R.id.textView_phone);
price=(TextView)findViewById(R.id.textView_price);
product=(ImageView)findViewById(R.id.imageView);

Bundle bundle = getIntent().getExtras();

String url = bundle.getString("Image");

phone.setText(bundle.getString("Your string key"));
price.setText(bundle.getString("Your string key"));

Picasso.with(getApplicationContext()).load(url).into(product);
