Aislamiento de un enlace en RSS Feed

Question

Soy nuevo en la programación así que por favor, no me moleste, he estado jugando con un simple lector de RSS, tratando de obtener el enlace a la artice para abrir en una vista web cuando el usuario hace clic el artículo.

He encontrado la cadena que controla y almacena el enlace, pero cuando trato de imprimir el enlace en el brindis aparece el enlace pero con la fecha de publicación del artículo completo ect ... ¿cómo puedo obtener el enlace para imprimirlo? propia y qué comandos necesito para utilizar para pasar el enlace a la vista web una vez que haya aislado, aquí es una parte del código que tengo

RSSActivity

public class RssActivity extends ListActivity {

     super.onCreate(savedInstanceState); 
     List<JSONObject> jobs = new ArrayList<JSONObject>(); 
     try { 
      jobs = RssReader.getLatestRssFeed(); 
     } catch (Exception e) { 
      Log.e("RSS ERROR", "Error loading RSS Feed Stream >> " + e.getMessage() + " //" + e.toString()); 
     } 

     adapter = new RssListAdapter(this,jobs); 
     setListAdapter(adapter); 
    } 
    protected void onListItemClick(ListView l, View v, int position, long id) { 
     super.onListItemClick(l, v, position, id); 
     // Get the item that was clicked 
     Object o = this.getListAdapter().getItem(position); 
     adapter.getItem(position).toString();

Answer 1

probar este

protected void onListItemClick(ListView l, View v, int position, long id) { 
     super.onListItemClick(l, v, position, id); 
     // Get the item that was clicked 
     JSONObject o = (JSONObject) this.getListAdapter().getItem(position); 
     adapter.getItem(position).toString(); 
     String link = o.getString("NameOfLinkInJsonObject"); 


     Toast.makeText(this, "You selected: " + link, Toast.LENGTH_LONG) 
       .show(); 

     mMyWebView.loadUrl(link); 
    } 

ser consciente de que debe arreglar "NameOfLinkInJsonObject".

En su actividad de agregar un campo al igual que

private WebView mMyWebView; 

En el método onCreate añadir un

mMyWebView = (WebView) findViewById(R.id.webViewId); 

Tendrá que cambiar el R.id.webViewId a la identificación apropiada para tu web ver.

Open URL in default browser Open URL with Android

Si tiene la dirección URL o un objeto URI en un punto, probablemente una de las explicaciones en los enlaces de arriba te llevará en tu camino.

- Editar:

protected void onListItemClick(ListView l, View v, int position, long id) { 
    super.onListItemClick(l, v, position, id); 
    // Get the item that was clicked 
    Object o = this.getListAdapter().getItem(position); 
    adapter.getItem(position).toString(); 
    String link = o.toString(); 
    Toast.makeText(this, "You selected: " + link, Toast.LENGTH_LONG) 
      .show(); 
} 

conjeturando que esto es el código para mostrar el enlace pero si usted no nos proporciona lo que el método getListAdapter(), etc hacer entonces me temo que es duro para ayudar vete.
