本文介绍了五种不同的动画实现方式,其实归根结底,就是下面几种:
1.AnimationSet(该方式使用所有android版本)但是使用不够灵活
下面的几种均只支持3.0以上的andorid系统
2.ObjectAnimator
3.PropertyValuesHolder
4.ValueAnimator
5.ViewPropertyAnimator,个人认为,对于不太的复杂的动画效果,该方法最为简单。
如:一行代码实现旋转加平移的效果
mView.animate().translationX(sTranslation).rotation(180).setDuration(1000).start();
话不多说,上代码:
