How to scale one view to another

Question

How do you scale one view to another? I tried finding scale x and scale y by dividing the width and height of each view, but it doesn't return the right value.

Scale a -> b.

a.setPivotX(0);
a.setPivotY(0);
a.setScaleX(b.getWidth() / a.getWidth())
a.setScaleY(b.getHeight() / a.getHeight())

@pskink @thestalker View `a` is smaller than view `b`. I would like to scale `a `to the same size as `b`. — user5180211, Aug 01 '15 at 08:45
are a and b the children of the same layout? if so, what kind of Layout? — pskink, Aug 01 '15 at 08:49
`FrameLayout`s lay out its children to have the same size by default — pskink, Aug 01 '15 at 08:58

firstly, you should call getWidth() and getHeight() after the view is be measured maybe after onResume(). this question maybe helpful

secondly, getWidth() and getHeight() return int, int/int will get a int but not a float. you may do like this (float) getWidth() / getHeight().

sorry for my poor English.
