類似系統聯系人頭部拼音推擠效果。

它實現的功能包括：

Fast scroll

Headers and footers

Clickable pinned sections

用法：

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" 
    />

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>;
     }
}
