Soluzione per finire l'activity "cerca"

[Carontes]

Salve, nella mia applicazione ho inserito l'activity "cerca" contenente due tabhost. In un tab si cerca digitando un nome e nell'altro si cerca tramite spinner.

I nomi "Antonio, Arma..." li ho in un file .xml situato dentro la cartell res/raw. Come faccio a fare un intent, in modo che una volta premuto il nome che mi serve mi visualizzi una pagina informativa sul nome premuto? Premetto che il layout per la pagina informativa già ce l'ho. Grazie.
