Question

Basically I have two tabs. A Fragment and a ListFragment.

When in the Fragment, you can insert data into a Database that will populate a ListView in the ListFragment Tab directly next to it. I want to be able to swipe to that ListFragment (after inserting new data) and while using the ViewPager function for swiping, I want the ListView to refresh.

Is there a proper way to do this? I can show code if requested; but not sure which code to show. To start, here is my View pager setup:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.fragment_layout);

    mSectionsPagerAdapter = new SectionsPagerAdapter(
            getSupportFragmentManager());

    final ActionBar actionBar = getActionBar();
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
    actionBar.setDisplayHomeAsUpEnabled(true);

    mViewPager = (ViewPager) findViewById(R.id.viewpager);
    mViewPager.setAdapter(mSectionsPagerAdapter);

    mViewPager
            .setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
                @Override
                public void onPageSelected(int position) {
                    actionBar.setSelectedNavigationItem(position);
                }
            });

    for (int i = 0; i < mSectionsPagerAdapter.getCount(); i++) {
        actionBar.addTab(actionBar.newTab()
                .setText(mSectionsPagerAdapter.getPageTitle(i))
                .setTabListener(this));
    }

}

Please note: This is NOT a dual pane setup.

The proper way to do it is to have your ListFragment implement the LoaderManager.LoaderCallbacks<D> interface and initialize a Loader to load the data being bound to the ListView.
