揭示效果布局，可以指定2个子布局，以圆形揭示效果切换选中状态
- 在项目根目录的build.gradle添加仓库地址
allprojects {
repositories {
...
maven { url 'https://www.jitpack.io' }
}
}- 在项目app目录的build.gradle添加依赖
从1.1.1版本开始，版本号前不加v，引用时需要注意。

});如一个关注取消关注控件FollowView，只需要继承RevealLayout，然后复写以下3个方法：
- initAttr(AttributeSet attrs)：获取子类的自定义属性
- createCheckedView()：创建选中状态视图，并初始化自定义属性
- createUncheckedView()：创建非选中状态视图，并初始化自定义属性
