Как отправить строку, извлеченную Jsoup, другой активности в Android Studio?

Question

У меня есть эта проблема. В моей деятельности (TripActivity.java) я извлек строку из URL. Затем, когда я нажимаю кнопку в своей активности, я хочу, чтобы извлеченная строка была вставлена ​​в текстовое представление во втором действии (EventActivity.java). Строка, которую я хочу передать, - linkText. Я пробовал с putExtra, но он не работает.

Моя первая Деятельность:

public class TripActivity extends Activity implements View.OnClickListener { 

private ImageButton btColosseo; 
private ImageButton btArcoCostantino; 
private ImageButton btDomus; 
private ImageButton btForo; 
private ImageButton btConfermaViaggio; 
private String monumento = "null"; 

private String Visita1 = "Colosseo"; 
private String Visita2 = "Domus Aurea"; 
private String Visita3 = "Arco di Costantino"; 
private String Visita4 = "Foro Romano e Palatino"; 

public static final String BASE_URL = "http://archeoroma.beniculturali.it/siti-archeologici/"; 


private static final String LOG_TAG = "TripActivity"; 
private String NomeMonumento; 
public String linkText= ""; 


@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_trip); 

    Bundle datipassati = getIntent().getExtras(); 
    String Viaggio = datipassati.getString("Viaggio"); 
    String Citta = datipassati.getString("Citta"); 
    int Budget = getIntent().getIntExtra("Budget", -1); 
    String Percorso = datipassati.getString("Percorso"); 
    Boolean Shopping = datipassati.getBoolean("Shopping"); 
    Boolean Cultura = datipassati.getBoolean("Cultura"); 
    Boolean Cucina = datipassati.getBoolean("Cucina"); 
    Boolean Eventi = datipassati.getBoolean("Eventi"); 


    Log.d(LOG_TAG, Viaggio); 
    Log.d(LOG_TAG, Citta); 
    Log.d(LOG_TAG, "Il budget e':" + Budget); 
    Log.d(LOG_TAG, Percorso);

Я упростить код и добавить комментарий, чтобы облегчить решение проблемы

public class TripActivity extends Activity implements View.OnClickListener {
