public class FrameLayout extends ViewGroup
android:layout_gravity
attribute.
Child views are drawn in a stack, with the most recently added child on top.
The size of the FrameLayout is the size of its largest child (plus padding), visible
or not (if the FrameLayout's parent permits). Views that are View.GONE
are
used for sizing
only if setConsiderGoneChildrenWhenMeasuring()
is set to true.

protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
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()
).
