Finally, Google released an official version of pull-to-refresh library! It is called  SwipeRefreshLayout , inside the support library, and the documentation is  here : 1)  Add  SwipeRefreshLayout  as a parent of view which will be treated as pull to refresh layout. (I took  ListView  as an example, it can be any  View  like  LinearLayout ,  ScrollView  etc.) <android.support.v4.widget.SwipeRefreshLayout android:id = "@+id/pullToRefresh" android:layout_width = "match_parent" android:layout_height = "wrap_content" > <ListView android:id = "@+id/listView" android:layout_width = "match_parent" android:layout_height = "match_parent" /> </android.support.v4.widget.SwipeRefreshLayout> 2)  Add a listener to your class protected void onCreate ( Bundle savedInstanceState ) { SwipeRefreshLayout pullToRefresh = findViewById ( R . id . pullToRefr...
