Android de support kütüphanesi ile birlikte gelen SwipeRefreshLayoutuda kullanabilirsin.

orda arkadaşın bahsettiği library dosyayı indirdikten projene import et seOn...listener  da metodunu getRefreshableView()  çagır

layoutuna bunu ekle
<com.handmark.pulltorefresh.library.PullToRefreshListView

android:id="@+id/pull_to_refresh_listview"

android:layout_height="fill_parent"

android:layout_width="fill_parent" />

Activitine de bunu ekle 

PullToRefreshListView pullToRefreshView = (PullToRefreshListView) findViewById(R.id.pull_to_refresh_listview);

pullToRefreshView.setOnRefreshListener(new OnRefreshListener<ListView>() {

@Override

public void onRefresh(PullToRefreshBase<ListView> refreshView) {

// Do work to refresh the list here. new

GetDataTask().execute();

} } );

private class GetDataTask extends AsyncTask<Void, Void, String[]> {

...

@Override

protected void onPostExecute(String[] result) {

// Call onRefreshComplete when the list has been refreshed.

pullToRefreshView.onRefreshComplete();

super.onPostExecute(result);

} }
