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.

Inherited methods

From class


        
          android.widget.BaseExpandableListAdapter

`boolean`	`areAllItemsEnabled()`
`int`	`getChildType(int groupPosition, int childPosition)` Get the type of child View that will be created by `ExpandableListAdapter.getChildView(int, int, boolean, View, ViewGroup)` for the specified child item.
`int`	`getChildTypeCount()` Returns the number of types of child Views that will be created by `ExpandableListAdapter.getChildView(int, int, boolean, View, ViewGroup)` .
`long`	`getCombinedChildId(long groupId, long childId)` Override this method if you foresee a clash in IDs based on this scheme: Base implementation returns a long: bit 0: Whether this ID points to a child (unset) or group (set), so for this method this bit will be 1.
`long`	`getCombinedGroupId(long groupId)` Override this method if you foresee a clash in IDs based on this scheme: Base implementation returns a long: bit 0: Whether this ID points to a child (unset) or group (set), so for this method this bit will be 0.
`int`	`getGroupType(int groupPosition)` Get the type of group View that will be created by `ExpandableListAdapter.getGroupView(int, boolean, View, ViewGroup)` .
`int`	`getGroupTypeCount()` Returns the number of types of group Views that will be created by `ExpandableListAdapter.getGroupView(int, boolean, View, ViewGroup)` .
`boolean`	`isEmpty()`
`void`	`notifyDataSetChanged()`
`void`	`notifyDataSetInvalidated()`
`void`	`onGroupCollapsed(int groupPosition)` Called when a group is collapsed.
`void`	`onGroupExpanded(int groupPosition)` Called when a group is expanded.
`void`	`registerDataSetObserver(DataSetObserver observer)`
`void`	`unregisterDataSetObserver(DataSetObserver observer)`

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.
