Spruce is a lightweight animation library that helps choreograph the animations on the screen. With so many different animation libraries out there, developers need to make sure that each view is animating at the appropriate time. Spruce can help designers request complex multi-view animations and not have the developers cringe at the prototype.
Spruce是一个轻量级的动画库，可帮助编排屏幕上的动画。 由于存在许多不同的动画库，开发人员需要确保每个视图都在适当的时间进行动画处理。 云杉可以帮助设计人员请求复杂的多视图动画，而无需开发人员屈服于原型。
Chips were presented in Material Design. They

Some time ago Google updated Material Design guideline, and introduced bottom navigation bars, as one of several good UI patters to follow in our apps. They also added the implementation to the Design Support Library.
不久前，Google更新了Material Design指南，并引入了底部导航栏，将其作为应用程序中可以遵循的几种不错的UI模式之一。 他们还将实现添加到了设计支持库中。
Adaptable Bottom Navigation can easily replace BottomNavigationView from Support Library. It is implemented in the way how ViewPager and TabLayout work. This is a short explanation from Buffer team:
自适应的底部导航可以轻松替换支持库中的BottomNavigationView 。 它是通过ViewPager和TabLayout工作方式实现的。 这是Buffer团队的简短解释：
As mentioned, when using the Bottom Navigation View from the Android Support Library, there can be a lot of boilerplate code for the switching of views. Because of this, we took inspiration from the TabLayout setupWithViewPager() method and created a custom ViewSwapper component that can be attached to a Bottom Navigation View to simplify the management of view display.
如前所述，在使用Android支持库中的底部导航视图时，可能会有很多样板代码用于视图切换。 因此，我们从TabLayout setupWithViewPager()方法获得了启发，并创建了一个自定义ViewSwapper组件，该组件可以附加到底部导航视图以简化视图显示的管理。
