Android項目怎么使用RecyclerView實現(xiàn)一個點擊事件

protected void onCreate(Bundle savedInstanceState) { 
  super.onCreate(savedInstanceState); 
  setContentView(R.layout.activity_main); 
 
  initView(); 
 } 
 
 private void initView() { 
  recyclerView = (RecyclerView) findViewById(R.id.rv); 
  // use this setting to improve performance if you know that changes 
  // in content do not change the layout size of the RecyclerView 
  recyclerView.setHasFixedSize(true); 
  // use a linear layout manager 
  LinearLayoutManager ll = new LinearLayoutManager(this); 
  recyclerView.setLayoutManager(ll); 
  initializeData(); 
  recyclerAdapter = new RecyclerAdapter(persons); 
  recyclerView.setAdapter(recyclerAdapter); 
 
 } 
 
 
 private void initializeData(){ 
  persons = new ArrayList<>(); 
  persons.add(new Person("Emma Wilson", "23 years old", R.mipmap.ic_launcher)); 
  persons.add(new Person("Lavery Maiss", "25 years old", R.mipmap.ic_launcher)); 
  persons.add(new Person("Lillie Watts", "35 years old", R.mipmap.ic_launcher)); 
 } 

public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.ViewHolder>{ 
 private List<Person> list;

 } 
 
 //為ViewHolder設(shè)置數(shù)據(jù) 
 @Override 
 public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
  View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item, parent, false); 
  ViewHolder viewHolder = new ViewHolder(view); 
  return viewHolder; 
 } 
 
 @Override

  super.onAttachedToRecyclerView(recyclerView); 
 } 
 
 //用于創(chuàng)建ViewHolder 
 @Override

  Person person = list.get(position); 
  holder.nameTv.setText(person.name); 
  holder.ageTv.setText(person.age); 
  holder.imageView.setImageResource(person.photoId); 
 } 
 
 @Override 
 public int getItemCount() { 
  return list.size(); 
 } 
 
 // 刪除指定的Item 
 public void removeData(int position) 
 { 
  list.remove(position); 
  // 通知RecyclerView控件某個Item已經(jīng)被刪除 
  notifyItemRemoved(position); 
 
 } 
 // 在指定位置添加一個新的Item 
 public void addItem(Person person,int positionToAdd) 
 { 
  list.add(person); 
  // 通知RecyclerView控件插入了某個Item 
  notifyItemInserted(positionToAdd); 
 }

  }
