View
Measure the view and its content to determine the measured width and the
measured height. This method is invoked by View.measure(int, int)
and
should be overriden by subclasses to provide accurate and efficient
measurement of their contents.
CONTRACT: When overriding this method, you
must call View.setMeasuredDimension(int, int)
to store the
measured width and height of this view. Failure to do so will trigger an
IllegalStateException
, thrown by
View.measure(int, int)
. Calling the superclass'
View.onMeasure(int, int)
is a valid use.
The base class implementation of measure defaults to the background size,
unless a larger size is allowed by the MeasureSpec. Subclasses should
override View.onMeasure(int, int)
to provide better measurements of
their content.
If this method is overridden, it is the subclass's responsibility to make
sure the measured height and width are at least the view's minimum height
and width (View.getSuggestedMinimumHeight()
and
View.getSuggestedMinimumWidth()
).

View
This method is called whenever a pointer is hovering into, over, or out of the
bounds of a view and the view is not currently being touched.
Hover events are represented as pointer events with action
MotionEvent.ACTION_HOVER_ENTER
, MotionEvent.ACTION_HOVER_MOVE
,
or MotionEvent.ACTION_HOVER_EXIT
.
MotionEvent.ACTION_HOVER_ENTER
when the pointer enters the bounds of the view.MotionEvent.ACTION_HOVER_MOVE
when the pointer has already entered the bounds of the view and has moved.MotionEvent.ACTION_HOVER_EXIT
when the pointer has exited the bounds of the view or when the pointer is
about to go down due to a button click, tap, or similar user action that
causes the view to be touched.The view should implement this method to return true to indicate that it is handling the hover event, such as by changing its drawable state.
The default implementation calls View.setHovered(boolean)
to update the hovered state
of the view when a hover enter or hover exit event is received, if the view
is enabled and is clickable. The default implementation also sends hover
accessibility events.
