MultiLevelListView is an Open Source Android library providing view for displaying items grouped into levels and sub-levels. Levels hierarchy size is not limited. Any particular data model is not required, it fully depends on developer.

MultiLevelListView is simple in use. Like Android's ListView, it requires to extend and provide an Adapter object (MultiLevelListAdapter). The adapter has three methods that have to be implemented:

• boolean isExpandable(Object object) Indicates if particular data object is an expandable object

• List<?> getSubObjects(Object object) Get sub-objects for particular data object if the object is expandable

• View getViewForObject(Object object, View convertView, ItemInfo itemInfo) Get a view for displaying data object. Old view is provided to reuse if is available. Additionally ItemInfo object is provided with additional information about object and its location on the list. This information can be used for styling the view.

For detailed information how to use the library please check included sample application and source codes.
