Fields Summary

Constructors Summary

Methods Summary
public boolean	areAllItemsEnabled() see ListAdapter#areAllItemsEnabled()
public java.lang.Object	getChild(int groupPosition, int childPosition) Gets the data associated with the given child within the given group. param groupPosition the position of the group that the child resides in param childPosition the position of the child with respect to other children in the group return the data of the child
public long	getChildId(int groupPosition, int childPosition) Gets the ID for the given child within the given group. This ID must be unique across all children within the group. The combined ID (see {@link #getCombinedChildId(long, long)}) must be unique across ALL items (groups and all children). param groupPosition the position of the group that contains the child param childPosition the position of the child within the group for which the ID is wanted return the ID associated with the child
public android.view.View	getChildView(int groupPosition, int childPosition, boolean isLastChild, android.view.View convertView, android.view.ViewGroup parent) Gets a View that displays the data for the given child within the given group. param groupPosition the position of the group that contains the child param childPosition the position of the child (for which the View is returned) within the group param isLastChild Whether the child is the last child within the group param convertView the old view to reuse, if possible. You should check that this view is non-null and of an appropriate type before using. If it is not possible to convert this view to display the correct data, this method can create a new view. It is not guaranteed that the convertView will have been previously created by {@link #getChildView(int, int, boolean, View, ViewGroup)}. param parent the parent that this view will eventually be attached to return the View corresponding to the child at the specified position
public int	getChildrenCount(int groupPosition) Gets the number of children in a specified group. param groupPosition the position of the group for which the children count should be returned return the children count in the specified group
public long	getCombinedChildId(long groupId, long childId) Gets an ID for a child that is unique across any item (either group or child) that is in this list. Expandable lists require each item (group or child) to have a unique ID among all children and groups in the list. This method is responsible for returning that unique ID given a child's ID and its group's ID. Furthermore, if {@link #hasStableIds()} is true, the returned ID must be stable as well. param groupId The ID of the group that contains this child. param childId The ID of the child. return The unique (and possibly stable) ID of the child across all groups and children in this list.
public long	getCombinedGroupId(long groupId) Gets an ID for a group that is unique across any item (either group or child) that is in this list. Expandable lists require each item (group or child) to have a unique ID among all children and groups in the list. This method is responsible for returning that unique ID given a group's ID. Furthermore, if {@link #hasStableIds()} is true, the returned ID must be stable as well. param groupId The ID of the group return The unique (and possibly stable) ID of the group across all groups and children in this list.
public java.lang.Object	getGroup(int groupPosition) Gets the data associated with the given group. param groupPosition the position of the group return the data child for the specified group
public int	getGroupCount() Gets the number of groups. return the number of groups
public long	getGroupId(int groupPosition) Gets the ID for the group at the given position. This group ID must be unique across groups. The combined ID (see {@link #getCombinedGroupId(long)}) must be unique across ALL items (groups and all children). param groupPosition the position of the group for which the ID is wanted return the ID associated with the group
public android.view.View	getGroupView(int groupPosition, boolean isExpanded, android.view.View convertView, android.view.ViewGroup parent) Gets a View that displays the given group. This View is only for the group--the Views for the group's children will be fetched using getChildrenView. param groupPosition the position of the group for which the View is returned param isExpanded whether the group is expanded or collapsed param convertView the old view to reuse, if possible. You should check that this view is non-null and of an appropriate type before using. If it is not possible to convert this view to display the correct data, this method can create a new view. It is not guaranteed that the convertView will have been previously created by {@link #getGroupView(int, boolean, View, ViewGroup)}. param parent the parent that this view will eventually be attached to return the View corresponding to the group at the specified position
public boolean	hasStableIds() Indicates whether the child and group IDs are stable across changes to the underlying data. return whether or not the same ID always refers to the same object see Adapter#hasStableIds()
public boolean	isChildSelectable(int groupPosition, int childPosition) Whether the child at the specified position is selectable. param groupPosition the position of the group that contains the child param childPosition the position of the child within the group return whether the child is selectable.
public boolean	isEmpty() see ListAdapter#isEmpty()
public void	onGroupCollapsed(int groupPosition) Called when a group is collapsed. param groupPosition The group being collapsed.
public void	onGroupExpanded(int groupPosition) Called when a group is expanded. param groupPosition The group being expanded.
public void	registerDataSetObserver(android.database.DataSetObserver observer) see Adapter#registerDataSetObserver(DataSetObserver)
public void	unregisterDataSetObserver(android.database.DataSetObserver observer) see Adapter#unregisterDataSetObserver(DataSetObserver)
