TextView TextSize Animation

WoWoTextViewTextSizeAnimation changes the text size of a TextView instance. Any sub-class extends TextView is able to perform this animation.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ViewAnimation viewAnimation = new ViewAnimation(findViewById(R.id.test));
    viewAnimation.add(WoWoTextViewTextSizeAnimation.builder().page(0)
            .fromSp(50).toSp(20).build());
    viewAnimation.add(WoWoTextViewTextSizeAnimation.builder().page(1)
            .fromSp(20).toSp(60).build());
    viewAnimation.add(WoWoTextViewTextSizeAnimation.builder().page(2)
            .fromSp(60).toSp(5).build());
    viewAnimation.add(WoWoTextViewTextSizeAnimation.builder().page(3).start(0).end(0.5)
            .fromSp(5).toSp(50).build());
    viewAnimation.add(WoWoTextViewTextSizeAnimation.builder().page(3).start(0.5).end(1)
            .fromSp(50).toSp(30).build());
    wowo.addAnimation(viewAnimation);
    wowo.setEase(ease);
    wowo.setUseSameEaseBack(useSameEaseTypeBack);
    wowo.ready();
