    />

Activity

// Set a listener to be invoked when the list should be refreshed.
((PullToRefreshListView) getListView()).setOnRefreshListener(new OnRefreshListener() {
    @Override
    public void onRefresh() {
        // Do work to refresh the list here.
        new GetDataTask().execute();
    }
});

private class GetDataTask extends AsyncTask<Void, Void, String[]> {
    ...
    @Override
    protected void onPostExecute(String[] result) {
        mListItems.addFirst("Added after refresh...");
        // Call onRefreshComplete when the list has been refreshed.
        ((PullToRefreshListView) getListView()).onRefreshComplete();
        super.onPostExecute(result);
    }
}
