SimpleExpandableListAdapter

public class SimpleExpandableListAdapter
extends BaseExpandableListAdapter

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

一个简单的适配器，可将静态数据映射到XML文件中定义的组和子视图。 您可以单独指定支持该组的数据作为地图列表。 ArrayList中的每个条目都对应于展开列表中的一个组。 地图包含每行的数据。 您还可以指定一个XML文件，该文件定义用于显示组的视图以及从映射中的键到特定视图的映射。 这个过程对于一个孩子来说是相似的，除了它是更深一层的，所以数据支持被指定为一个List >，其中第一个列表对应于孩子的组，第二个列表对应于组内孩子的位置，最后地图保存该特定孩子的数据。

                String[] childFrom, 
                int[] childTo)

构造函数

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.
