Introduction

Easy to use ListView with pinned sections for Android. Pinned section is a header view which sticks to the top of the list until at least one item of that section is visible.

   

Features

This list properly implements many features which are missing from other implementations. These are

• Fast scroll
• Headers and footers
• Clickable pinned sections

Besides this it doesn't create any unnecessary views, layouts etc. It's really lean.

Watch this video to see PinnedSectionListView in action.

Usage

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>;
        }
   }
   

That's all. You are done! A working example can also be found in example folder.
