-/**
- * Implements a ListView class with a sticky header at the top. The header is
- * per section and it is pinned to the top as long as its section is at the top
- * of the view. If it is not, the header slides up or down (depending on the
- * scroll movement) and the header of the current section slides to the top.
- * Notes:
- * 1. The class uses the first available child ListView as the working
- *    ListView. If no ListView child exists, the class will create a default one.
- * 2. The ListView's adapter must be passed to this class using the 'setAdapter'
- *    method. The adapter must implement the HeaderIndexer interface. If no adapter
- *    is specified, the class will try to extract it from the ListView
- * 3. The class registers itself as a listener to scroll events (OnScrollListener), if the
- *    ListView needs to receive scroll events, it must register its listener using
- *    this class' setOnScrollListener method.
- * 4. Headers for the list view must be added before using the StickyHeaderListView
- * 5. The implementation should register to listen to dataset changes. Right now this is not done

+ * Notes:
+ * 1. The class uses the first available child ListView as the working
+ * ListView. If no ListView child exists, the class will create a default one.
+ * 2. The ListView's adapter must be passed to this class using the 'setAdapter'
+ * method. The adapter must implement the HeaderIndexer interface. If no adapter
+ * is specified, the class will try to extract it from the ListView
+ * 3. The class registers itself as a listener to scroll events (OnScrollListener), if the
+ * ListView needs to receive scroll events, it must register its listener using
+ * this class' setOnScrollListener method.
+ * 4. Headers for the list view must be added before using the StickyHeaderListView
+ * 5. The implementation should register to listen to dataset changes. Right now this is not done
+ * since a change the dataset in a listview forces a call to OnScroll. The needed code is
