Now you can call this your method from any other class like:
// ===== Inside Another class === //
private String[] _animationList = { "fade", "flipHorizontal",
"flipVertical", "disappearTopLeft", "appearTopLeft",
"appearBottomRight", "disappearBottomRight", "unzoom" };
ActivityAnimator anim = new ActivityAnimator();
anim.getClass().getMethod(_animationList[arg2] + "Animation",Activity.class).invoke(anim, this);
