TextView Text Animation

WoWoTextViewTextAnimation helps to change text in an instance of TextView. Any views that extends TextView is accepted to this animation. Check the demo activity for usage details:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    addTextAnimation(findViewById(R.id.test0), WoWoTypewriter.InsertFromLeft);
    addTextAnimation(findViewById(R.id.test1), WoWoTypewriter.DeleteThenType);
    addTextAnimation(findViewById(R.id.test2), WoWoTypewriter.InsertFromRight);

    wowo.setEase(ease);
    wowo.setUseSameEaseBack(useSameEaseTypeBack);
    wowo.ready();
}
private void addTextAnimation(View view, Typewriter typewriter) {
    wowo.addAnimation(view)
            .add(WoWoTextViewTextAnimation.builder().page(0)
                    .from("Nightonke").to("WoWoViewPager").typewriter(typewriter).build())
            .add(WoWoTextViewTextAnimation.builder().page(1)
                    .from("WoWoViewPager").to("").typewriter(typewriter).build())
            .add(WoWoTextViewTextAnimation.builder().page(2)
                    .from("").to("Nightonke").typewriter(typewriter).build())
            .add(WoWoTextViewTextAnimation.builder().page(3).start(0).end(0.5)
                    .from("Nightonke").to("Huang").typewriter(typewriter).build())
            .add(WoWoTextViewTextAnimation.builder().page(3).start(0.5).end(1)
                    .from("Huang").to("Weiping").typewriter(typewriter).build());
}

WoWoTextViewTextAnimation extends TextPageAnimation. In TextPageAnimation, you can define your own text-transformation-rule by providing an implementation of Typewriter. Check Typewriter Wiki for more details. As like other animations, WoWoTextViewTextAnimation extends PageAnimation too. Check more implementation details in its superclasses.
