I'm trying to make a basic Tourist app for my hometown. I have an onItemClickListener set on a listView. My goal is that when a list item is clicked, I want to open a new activity to show the user more information about the selected item(address, phone number, GPS location, etc). I set all the textviews in the fragment before I send the intent, so, when I setContentView, it should be displayed with all the accurate information already populated.
The problem is, when the list view is clicked, the activity starts a blank activity. There is no error message and the logCat shows that the textviews were updated correctly but they just aren't displaying correctly with the layout.
I've been working on this for days and would appreciate any help that anyone can give. Thanks in advance. Code is below.
**This is the fragment that holds the arrayList with the information to be displayed.
public class FoodFragment extends Fragment {
public FoodFragment() {
// Required empty public constructor
}
public TourSite currentSite;
@Override
public View onCreateView(final LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.sites_listview, container, false);
// Create an ArrayList of TourSite objects for main tab lists
final ArrayList<TourSite> tourSites = new ArrayList<TourSite>();
tourSites.add(new TourSite(R.string.ginasAddress, R.string.ginasNumber, R.string.ginasGPS,
R.string.ginasWeblink, R.drawable.pizza_100, R.string.ginasName));
tourSites.add(new TourSite(R.string.ninosAddress, R.string.ninosnumber, R.string.ninosGPS,
R.string.ninosWeblink, R.drawable.pizza_100, R.string.ninosName));
tourSites.add(new TourSite(R.string.topsAddress, R.string.topsDinerNumber,
R.string.topsDinerGPS, R.string.topsWeblink, R.drawable.restaurant_100,
R.string.topsName));
tourSites.add(new TourSite(R.string.goldenEagleAddress, R.string.goldenEagleNumber,
R.string.goldenEagleGPS, R.drawable.noodles_100, R.string.goldenEagleName));
//Creates adapter that displays tourSites on tabs
TourSiteListAdapter adapter = new TourSiteListAdapter(getActivity(), tourSites);
//finds the listview that were using to display the images and names
ListView listview = (ListView) rootView.findViewById(R.id.siteList);
listview.setAdapter(adapter);
//attaches Listener to listView in order to open new activity with further
// information about the toursite
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//finds the selected list item
currentSite = tourSites.get(position);
//inflates the layout we want to display using the intent below
LayoutInflater inflater1 = (LayoutInflater) getContext().getSystemService
(Context.LAYOUT_INFLATER_SERVICE);
View root = inflater1.inflate(R.layout.list_item_info, null, true);
//finds the textViews in the layout that we want to update before
// displaying in activity
TextView addressView = (TextView) root.findViewById(R.id.addressView);
TextView numberView = (TextView) root.findViewById((R.id.numberView));
TextView gpsView = (TextView) root.findViewById(R.id.gpsView);
TextView weblinkView = (TextView) root.findViewById(R.id.weblinkView);
//some toursites dont have phone numbers or websites. This handles that
// while also updateding the content to be displayed
if (currentSite.hasAddress()) {
addressView.setText(currentSite.getmAddress());
addressView.setVisibility(View.VISIBLE);
} else {
addressView.setVisibility(View.GONE);
}
if (currentSite.hasPhone()) {
numberView.setText(currentSite.getmPhone());
numberView.setVisibility(View.VISIBLE);
} else {
numberView.setVisibility(View.GONE);
}
gpsView.setText(currentSite.getmGPSlink());
gpsView.setMovementMethod(LinkMovementMethod.getInstance());
if (currentSite.hasWeblink()) {
weblinkView.setText(currentSite.getmWeblink());
weblinkView.setVisibility(View.VISIBLE);
weblinkView.setMovementMethod(LinkMovementMethod.getInstance());
} else {
weblinkView.setVisibility(View.GONE);
}
//used these logs to make sure the textviews were being updated correctly
Log.d("addressView = ", addressView.getText().toString());
Log.d("numberView = ", numberView.getText().toString());
Log.d("gpsView = ", "" + gpsView.getText().toString());
Log.d("weblinkView = ", weblinkView.getText().toString());
//starts new activity that displays tourSite info
Intent showInfo = new Intent(getContext(), TourSiteInfo.class);
startActivity(showInfo);
}
});
return rootView;
}
}
**This is the activity that is supposed to display the layout, but is blank
public class TourSiteInfo extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.list_item_info);
}
}

I've been researching and trying different solutions for days but nothing has worked yet.
