Method Detail

setOnItemGestureListener

public void setOnItemGestureListener(ItemizedLayer.OnItemGestureListener<Item> listener)

createItem

protected Item createItem(int index)

Description copied from class: MarkerLayer

Method by which subclasses create the actual Items. This will only be called from populate() we'll cache them for later use.

Specified by:

createItem in class MarkerLayer<Item extends MarkerInterface>

size

public int size()

Description copied from class: MarkerLayer

The number of items in this overlay.

Specified by:

size in class MarkerLayer<Item extends MarkerInterface>

addItem

public boolean addItem(Item item)

addItem

public void addItem(int location,
                    Item item)

addItems

public boolean addItems(java.util.Collection<Item> items)

getItemList

public java.util.List<Item> getItemList()

removeAllItems

public void removeAllItems()

removeAllItems

public void removeAllItems(boolean withPopulate)

removeItem

public boolean removeItem(Item item)

removeItem

public Item removeItem(int position)

onSingleTapUpHelper

protected boolean onSingleTapUpHelper(int index,
                                      Item item)

Each of these methods performs a item sensitive check. If the item is located its corresponding method is called. The result of the call is returned. Helper methods are provided so that child classes may more easily override behavior without resorting to overriding the ItemGestureListener methods.

onLongPressHelper

protected boolean onLongPressHelper(int index,
                                    Item item)

activateSelectedItems

protected boolean activateSelectedItems(MotionEvent event,
                                        ItemizedLayer.ActiveItem task)

When a content sensitive action is performed the content item needs to be identified. This method does that and then performs the assigned task on that item.

Returns:

true if event is handled false otherwise

onGesture

public boolean onGesture(Gesture g,
                         MotionEvent e)

Specified by:

onGesture in interface GestureListener
