本动画揭露库，已经兼容 android9.0 版本，提供 6 种类的揭露动画，如需更多效果，可自行拓展。
- 在你需要做动画的布局上，套上
RevealAnimationLayout就可以了，支持套任何布局！！！
<com.revealanimation.RevealAnimationLayout
android:id="@+id/animat_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<ImageView
android:layout_width="match_parent"
android:layout_height="400dp"
android:layout_marginLeft="50dp"
android:layout_marginRight="50dp"
android:scaleType="centerCrop"
android:src="@mipmap/test"/>
</com.revealanimation.RevealAnimationLayout>
// java 代码中，调用
mClipAnimationLayout.startAnimal(RevealAnimationLayout.AnimaType.Circle);
本库还是测试状态，欢迎各位进行 commit ，指出不正之处。或者可以新建 issue 提出问题，我将一一解答。
