| android.widget.ExpandableListAdapter |
 Known Indirect Subclasses
|
An adapter that links a ExpandableListView with the underlying
data. The implementation of this interface will provide access
to the data of the children (categorized by groups), and also instantiate
Views for children and groups.
| Public Methods | |||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
Gets the data associated with the given child within the given group.
| |||||||||||
Gets the ID for the given child within the given group.
| |||||||||||
Gets a View that displays the data for the given child within the given
group.
| |||||||||||
Gets the number of children in a specified group.
| |||||||||||
Gets an ID for a child that is unique across any item (either group or
child) that is in this list.
| |||||||||||
Gets an ID for a group that is unique across any item (either group or
child) that is in this list.
| |||||||||||
Gets the data associated with the given group.
| |||||||||||
Gets the number of groups.
| |||||||||||
Gets the ID for the group at the given position.
| |||||||||||
Gets a View that displays the given group.
| |||||||||||
Indicates whether the child and group IDs are stable across changes to the
underlying data.
| |||||||||||
Whether the child at the specified position is selectable.
| |||||||||||
Called when a group is collapsed.
| |||||||||||
Called when a group is expanded.
| |||||||||||
Gets the data associated with the given child within the given group.
| groupPosition | the position of the group that the child resides in |
|---|---|
| childPosition | the position of the child with respect to other children in the group |
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
getCombinedChildId(long, long)) must be unique across ALL items
(groups and all children).
| groupPosition | the position of the group that contains the child |
|---|---|
| childPosition | the position of the child within the group for which the ID is wanted |
Gets a View that displays the data for the given child within the given group.
| groupPosition | the position of the group that contains the child |
|---|---|
| childPosition | the position of the child (for which the View is returned) within the group |
| isLastChild | Whether the child is the last child within the group |
| 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
getChildView(int, int, boolean, View, ViewGroup). |
| parent | the parent that this view will eventually be attached to |
Gets the number of children in a specified group.
| groupPosition | the position of the group for which the children count should be returned |
|---|
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 hasStableIds() is true, the
returned ID must be stable as well.
| groupId | The ID of the group that contains this child. |
|---|---|
| childId | The ID of the child. |
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 hasStableIds() is true, the returned ID must be
stable as well.
| groupId | The ID of the group |
|---|
Gets the data associated with the given group.
| groupPosition | the position of the group |
|---|
Gets the number of groups.
Gets the ID for the group at the given position. This group ID must be
unique across groups. The combined ID (see
getCombinedGroupId(long)) must be unique across ALL items
(groups and all children).
| groupPosition | the position of the group for which the ID is wanted |
|---|
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
getChildView(int, int, boolean, View, ViewGroup).
| groupPosition | the position of the group for which the View is returned |
|---|---|
| isExpanded | whether the group is expanded or collapsed |
| 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
getGroupView(int, boolean, View, ViewGroup). |
| parent | the parent that this view will eventually be attached to |
Indicates whether the child and group IDs are stable across changes to the underlying data.
Whether the child at the specified position is selectable.
| groupPosition | the position of the group that contains the child |
|---|---|
| childPosition | the position of the child within the group |
Called when a group is collapsed.
| groupPosition | The group being collapsed. |
|---|
Called when a group is expanded.
| groupPosition | The group being expanded. |
