它实现的功能包括：

• Fast scroll
• Headers and footers
• Clickable pinned sections

用法：

1. Replace standard ListView with com.hb.views.PinnedSectionListView in your layout.xml file.

   <com.hb.views.PinnedSectionListView      android:id="@android:id/list"      android:layout_width="match_parent"      android:layout_height="wrap_content"       />

2. Extend your ListAdapter in a way that it implements PinnedSectionListAdapter interface, in addition to what it already implements. Basically you need to add a single isItemViewTypePinned(int viewType) method. This method must return true for all view types which have to be pinned.

   // Our adapter class implements 'PinnedSectionListAdapter' interface  class MyPinnedSectionListAdapter extends BaseAdapter implements PinnedSectionListAdapter {         ...         // We implement this method to return 'true' for all view types we want to pin       @Override       public boolean isItemViewTypePinned(int viewType) {           return viewType == <type to be pinned>;       }  }
