it should still fix some issue Reload your data when dialog is closed. You are adding data in your database only, not refreshing your listview.
Add this method in your fragment
code :
public void reload()
{
    myDB = new DB(mContext);
    people = getThisMonthsPeople( myDB.getAllPeople());
    myAdapter = new PersonAdapter(mContext, people)
    listView.setAdapter(myAdapter);
    if(myAdapter != null)
        myAdapter.notifyDataSetChanged();
}
myDB = new DB(mContext);
people = getThisMonthsPeople( myDB.getAllPeople());
listView.setAdapter(new PersonAdapter(mContext, people));
@Override
public void onResume()
{
    super.onResume();
    JanuaryFragment fragment = (JanuaryFragment) getSupportFragmentManager()
                    .findFragmentById(R.id.layout); // Replace "layout" with your layout where you are loading the fragment
    if (fragment != null) {
        fragment.reload();
    }
}
if(context instanceOf MainActivity)
    ((MainActivity)context).onResume();

this one helps. If you need to add anything that requires an Activity, you can obtain a reference to it by using getActivity() method from a fragment.
It's best to put it into onActivityCreated() method as it's

Does that help I'm trying to open and write to a Sqlite database in Android. According to the log output, it's not opening. I know that my syntax isn't great and I should be saving from a Party object instead of straight from the fragment interface, but my focus is really on the the process. Any help would be super helpful! , Try this
code :
 SqlDatabase dbEntry = new SqlDatabase(getActivity());
 SqlDatabase dbEntry = new SqlDatabase(this);

I think the issue was by ths following , You can't directly call openOrCreateDatabase() in a fragment because it is a method from Context. A fragment is not a context. To get the context / Activity, just call getActivity()
It will result in the following :
code :
SQLiteDatabase db = getActivity().openOrCreateDatabase("course", Context.MODE_PRIVATE, null);
view.findViewById(R.id.lst1);
arrayAdapter = new ArrayAdapter(getActivity(), R.layout.support_simple_spinner_dropdown_item, titles);
