Вот MainActivity.java

public class MainActivity extends AppCompatActivity {
    private List<Person> persons;
    private RecyclerView rv;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        rv=(RecyclerView)findViewById(R.id.rv);
        LinearLayoutManager llm = new LinearLayoutManager(this);
        rv.setLayoutManager(llm);
        rv.setHasFixedSize(true);
        ParseTitle parseTitle = new ParseTitle();
       // parseTitle.execute();
        initializeData();
        initializeAdapter();
    }
    private void initializeData() {
        persons = new ArrayList<>();
        persons.add(new Person("Emma Wilson", "23 years old", R.drawable.emma));
        persons.add(new Person("Lavery Maiss", "25 years old", R.drawable.lavery));
        persons.add(new Person("Lillie Watts", "35 years old", R.drawable.lillie));
    }
    private void initializeAdapter(){
        RVAdapter adapter = new RVAdapter(persons);
        rv.setAdapter(adapter);
    }
    class ParseTitle extends AsyncTask<Void, Void, HashMap<String,String>> {
        @Override
        protected HashMap<String, String> doInBackground(Void... params) {
            HashMap<String, String> hashMap = new HashMap<>();
            try {
                Document doc = Jsoup.connect("http://site.ru/").get();
                Elements links = doc.select(".mine_rubric_icon");
                for(Element link: links){
                    Element link1 = link.select("a[href]").first();
                    hashMap.put(link.text(), link1.attr("abs:href"));
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
            return hashMap;
        }
    }
}
