SimpleExpandableListAdapter

public class SimpleExpandableListAdapter
extends BaseExpandableListAdapter

java.lang.Object
   ↳ android.widget.BaseExpandableListAdapter
     ↳ android.widget.SimpleExpandableListAdapter


An easy adapter to map static data to group and child views defined in an XML file. You can separately specify the data backing the group as a List of Maps. Each entry in the ArrayList corresponds to one group in the expandable list. The Maps contain the data for each row. You also specify an XML file that defines the views used to display a group, and a mapping from keys in the Map to specific views. This process is similar for a child, except it is one-level deeper so the data backing is specified as a List>, where the first List corresponds to the group of the child, the second List corresponds to the position of the child within the group, and finally the Map holds the data for that particular child.

                String[] childFrom, 
                int[] childTo)

Constructor

Parameters
context Context: The context where the ExpandableListView associated with this SimpleExpandableListAdapter is running
groupData List: A List of Maps. Each entry in the List corresponds to one group in the list. The Maps contain the data for each group, and should include all the entries specified in "groupFrom"
groupLayout int: resource identifier of a view layout that defines the views for a group. The layout file should include at least those named views defined in "groupTo"
groupFrom String: A list of keys that will be fetched from the Map associated with each group.
groupTo int: The group views that should display column in the "groupFrom" parameter. These should all be TextViews. The first N views in this list are given the values of the first N columns in the groupFrom parameter.
childData List: A List of List of Maps. Each entry in the outer List corresponds to a group (index by group position), each entry in the inner List corresponds to a child within the group (index by child position), and the Map corresponds to the data for a child (index by values in the childFrom array). The Map contains the data for each child, and should include all the entries specified in "childFrom"
childLayout int: resource identifier of a view layout that defines the views for a child. The layout file should include at least those named views defined in "childTo"
childFrom String: A list of keys that will be fetched from the Map associated with each child.
childTo int: The child views that should display column in the "childFrom" parameter. These should all be TextViews. The first N views in this list are given the values of the first N columns in the childFrom parameter.
