Android 项目怎么使用RecyclerView实现一个点击事件

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));  }
