Remarks

Additional methods that when implemented make an ExpandableListAdapter take advantage of the Adapter view type mechanism.

An ExpandableListAdapter declares it has one view type for its group items and one view type for its child items. Although adapted for most ExpandableListViews, these values should be tuned for heterogeneous ExpandableListViews.

Lists that contain different types of group and/or child item views, should use an adapter that implements this interface. This way, the recycled views that will be provided to android.widget.ExpandableListAdapter#getGroupView(int, boolean, View, ViewGroup) and android.widget.ExpandableListAdapter#getChildView(int, int, boolean, View, ViewGroup) will be of the appropriate group or child type, resulting in a more efficient reuse of the previously created views.

Properties

ChildTypeCount

This method will only be called when the adapter is set on the AdapterView.

GroupTypeCount

This method will only be called when the adapter is set on the AdapterView.

Handle

Gets the JNI value of the underlying Android object.

(Inherited from IJavaObject)
JniIdentityHashCode

Returns the value of java.lang.System.identityHashCode() for the wrapped instance.

(Inherited from IJavaPeerable)

Methods

Disposed()

Called when the instance has been disposed.

(Inherited from IJavaPeerable)
DisposeUnlessReferenced()

If there are no outstanding references to this instance, then calls Dispose(); otherwise, does nothing.

(Inherited from IJavaPeerable)

Called when the instance has been finalized.

(Inherited from IJavaPeerable)
GetChildType(Int32, Int32)

Get the type of child View that will be created by android.widget.ExpandableListAdapter#getChildView(int, int, boolean, View, ViewGroup) for the specified child item.

GetGroupType(Int32)

Get the type of group View that will be created by android.widget.ExpandableListAdapter#getGroupView(int, boolean, View, ViewGroup) .

SetJniIdentityHashCode(Int32)

Set the value returned by JniIdentityHashCode.

(Inherited from IJavaPeerable)
SetJniManagedPeerState(JniManagedPeerStates) (Inherited from IJavaPeerable)
SetPeerReference(JniObjectReference)

Set the value returned by PeerReference.

(Inherited from IJavaPeerable)
UnregisterFromRuntime()

Unregister this instance so that the runtime will not return it from future Java.Interop.JniRuntime+JniValueManager.PeekValue invocations.

(Inherited from IJavaPeerable)
