android - How to rotate floating action button without rotaing shadow? -

-

i rotate fab in such simple way:

fab.startanimation(animationutils.loadanimation(this, r.anim.rotate));

rotate.xml:

<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android">     <rotate         android:fromdegrees="0"         android:todegrees="360"         android:pivotx="50%"         android:pivoty="50%"         android:duration="1000"/> </set>

this works, fab shadow rotates. need fab rotate (or src image, if there's difference).

did try animate method provided compat library? had same problem when using animation utils

final overshootinterpolator interpolator = new overshootinterpolator(); viewcompat.animate(fab).            rotation(135f).            withlayer().            setduration(300).            setinterpolator(interpolator).            start();

this question understanding interfaces in java. here simple example of implementing interfaces in java. interface parenta { void display(); } interface parentb { int display(); } class child implements parenta, parentb { @override public void display() { system.err.println("child parenta"); } //error : return type incompatible parentb.display() //so added method int return type @override public int display() { system.err.println("child parentb"); } } this case can happen in large java application 2 interface can have method same name. thought since return type different jvm know interface's method overriding. what best explanation this? situation make sense? thanks in advance because method same signature not allowed, confuses compiler detect exact override-equivalent method declared once. jls (§8.4.2) 2 methods or constructors, m , n, have same signature if have, ...
