Why Can I Not Get My App To Successfully Send Data From One Fragment To Another?

I cannot get my app to successfully send data from one fragment to another. MainActivity.java which sets up my fragment tabs package myPackage; public class MainActivity extends A

Solution 1:

Warning: Not the best way but would do for now. Better solution would be to use Interface and use them as callback. See Passing data between two Fragments in a VIewPager (Android) (NullPointerException) and Passing data beetwen fragments in viewpager

Change PersonInformation like this

public class PersonInformation extends Fragment {
    private View rootView;
    private DatabaseHelper myDBHelper;
    private Cursor informationCursor;
    private SimpleCursorAdapter mySimpleCursorAdapter;
    private TextView personIDDisplay;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){

        rootView = inflater.inflate(R.layout.person_information, container, false);
        return rootView;
    }

    public void init(string personId)
    {
        myDBHelper = new DatabaseHelper(getActivity());
        informationCursor = myDBHelper.getInformationCursor(personId);
        String[] fromColumns = {"firstname", "lastname", "homephone", "homeaddress"};
        int[] toViews = {R.id.firstname_textview, R.id.lastname_textview, R.id.homephone_textview, R.id.homeaddress_textview};
        mySimpleCursorAdapter = new SimpleCursorAdapter(getActivity(), R.layout.information_layout, informationCursor, fromColumns, toViews, 0);
        personIDDisplay = (TextView) rootView.findViewById(R.id.person_id_display);
        personIDDisplay.setText("Person ID: " + personId);
        ListView myListView = (ListView) rootView.findViewById(R.id.row_of_information);
        myListView.setAdapter(mySimpleCursorAdapter);
        myDBHelper.close();
    }
}

Replace

PersonInformation personInformation = new PersonInformation();
Bundle myBundle = new Bundle();
myBundle.putString("personID", personIDNumber);
personInformation.setArguments(myBundle);
getFragmentManager().beginTransaction().add(R.id.row_of_information, personInformation).commit();

with

String tag = "android:switcher:" + R.id.pager + ":" + "1";
PersonInformation f = (PersonInformation) getSupportFragmentManager().findFragmentByTag(tag);
f.init(personIDNumber);

in onItemClick of Home fragment
