I've been trying to replace the current fragment with another one when an item on the list view has been pressed. However when the button is pressed, the onClick method is fired but it does not replace the fragment.
JournalFragment.java
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.fragment_journal_view, container, false);
context = getContext();
ListView myView = (ListView) rootView.findViewById(R.id.listView);
TableControllerUser TCU = new TableControllerUser(context);
final TableControllerJournal TCJ = new TableControllerJournal(context);
int accID = TCU.getLoggedInId();
Cursor cursor = TCJ.getAllJournals(accID);
Cursor allFood = TCJ.getAllFoodJournals(accID);
Cursor allActivity = TCJ.getAllActivityJournals(accID);
Cursor[] cursors = {cursor, allFood, allActivity};
MergeCursor m = new MergeCursor(cursors);
final JournalAdapter adapter = new JournalAdapter(context, m, 0);
myView.setAdapter(adapter);
myView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Cursor c = (Cursor) adapter.getItem(position);
Toast.makeText(getActivity(), "onClick Pressed!", Toast.LENGTH_SHORT).show();
String title = c.getString(c.getColumnIndexOrThrow("title"));
if (title.contains("Glucose")) {
String glucose = c.getString(c.getColumnIndexOrThrow("glucose"));
String dateTime = c.getString(c.getColumnIndexOrThrow("glucose_time"));
String journalId = c.getString(c.getColumnIndexOrThrow("_id"));
String split[] = dateTime.split(" ");
String date = split[0];
String time = split[1];
Fragment gluFrag = new GlucoseFragment();
Bundle bundle = new Bundle();
bundle.putString("time", time);
bundle.putString("date", date);
bundle.putString("glucose", glucose);
bundle.putString("journalId", journalId);
gluFrag.setArguments(bundle);
((GraphActivity) getActivity()).replaceFragments(gluFrag, bundle);
}
}
});
return rootView;
// Inflate the layout for this fragment
}
}

EDIT 2
Tried Harron's and Vivek_Neel's methods, both of them work but cause this problem with the formatting
Putting android:layout_below="@+id/viewPager" in the linearLayout causes the fragment to no longer display
EDIT 3
Solved the formatting problem with this https://stackoverflow.com/a/34573034/5509513
