Try this from your AndroidTabRestaurantDescSearchListView activity    Intent intent    new Intent this RatingDescriptionSearchActivity class    intent putExtras  getIntent   getExtras      startActivity  intent        And then from RatingDescriptionSearchActivity activity just call    getIntent   getStringExtra  key
