活动概述
本次活动嘉宾是 John Hoford ，一位具有超过 30 年开发经验的 Google 资深工程师，在 Google I/O 大会、Android Dev Summit 等很多活动上做过很多分享。
活动面向 Android 开发者 ，主要向大家介绍和交流 Android Studio 中的 UI 设计工具，特别是他负责的 MotionEditor 与 MotionLayout 这块。
编者注：MotionEditor 是在 Android Studio 4.0 中提供的。MotionLayout 是 ConstraintLayout 的子类，具有 ConstraintLayout 的大多数功能，但又有些差异。
主题分享之后是现场交流环节，你对 Android Studio 中的设计工具有什么问题 可以直接向他提问，或者其它 Android 方面、一般编程方面的问题。因为机会难得，所以请参会者在活动前提前想好你想与嘉宾交流的话题，带着问题来。
