Android only check if gesture observers are attached
Assign a size and position to a view and all of its descendants This is the second phase of the layout mechanism. (The first is measuring). In this phase, each parent calls layout on all of its children to position them. This is typically done using the child measurements that were stored in the measure pass(). Derived classes should not override this method. Derived classes with children should override onLayout. In that method, they should call layout on each of their children.
Called from onLayout when native view position is about to be changed.
Left position, relative to parent
Top position, relative to parent
Right position, relative to parent
Bottom position, relative to parent
This is called to find out how big a view should be. The parent supplies constraint information in the width and height parameters. The actual measurement work of a view is performed in onMeasure(int, int), called by this method. Therefore, only onMeasure(int, int) can and must be overridden by subclasses.
Horizontal space requirements as imposed by the parent
Vertical space requirements as imposed by the parent
Removes listener(s) for the specified event name.
Comma delimited names of the events or gesture types the specified listener is associated with.
An optional parameter pointing to a specific listener. If not defined, all listeners for the event names will be removed.
An optional parameter which when set will be used to refine search of the correct callback which will be removed as event listener.
A basic method signature to hook an event listener (shortcut alias to the addEventListener method).
String corresponding to events (e.g.
"propertyChange"). Optionally could be used
more events separated by , (e.g.
"propertyChange", "change") or you
can use gesture types.
Callback function which will be executed when event is raised.
An optional parameter which will be used as
this context for callback execution.
Raised when a loaded event occurs.
Raised when an unloaded event occurs.
Raised when a back button is pressed. This event is raised only for android.
Raised before the view is shown as a modal dialog.
Raised after the view is shown as a modal dialog.
Derived classes can override this method to handle Android back button press.
Called from layout when this view should assign a size and position to each of its children. Derived classes with children should override this method and call layout on each of their children.
Left position, relative to parent
Top position, relative to parent
Right position, relative to parent
Bottom position, relative to parent
Measure the view and its content to determine the measured width and the measured height. This method is invoked by measure(int, int) and should be overriden by subclasses to provide accurate and efficient measurement of their contents. When overriding this method, you must call setMeasuredDimension(int, int) to store the measured width and height of this view. Failure to do so will trigger an exception, thrown by measure(int, int).
horizontal space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.
vertical space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.
This method must be called by onMeasure(int, int) to store the measured width and measured height. Failing to do so will trigger an exception at measurement time.
The measured width of this view. May be a complex bit mask as defined by MEASURED_SIZE_MASK and MEASURED_STATE_TOO_SMALL.
The measured height of this view. May be a complex bit mask as defined by MEASURED_SIZE_MASK and MEASURED_STATE_TOO_SMALL.
Android only to set the touch listener
Layout a child by taking into account its margins, horizontal and vertical alignments and a given bounds.
This parameter is not used. You can pass null.
Left position, relative to parent
Top position, relative to parent
Right position, relative to parent
Bottom position, relative to parent
Measure a child by taking into account its margins and a given measureSpecs.
This parameter is not used. You can pass null.
The view to be measured.
The measured height that the parent layout specifies for this view.
The measured width that the parent layout specifies for this view.
Utility to reconcile a desired size and state, with constraints imposed by a MeasureSpec. Will take the desired size, unless a different size is imposed by the constraints. The returned value is a compound integer, with the resolved size in the MEASURED_SIZE_MASK bits and optionally the bit MEASURED_STATE_TOO_SMALL set if the resulting size is smaller than the size the view wants to be.
Represents a UI widget which displays a progress indicator hinting the user for some background operation running.
