This time we are going deep into viewgroup, understanding the work of viewgroup, and will explain more about the view of the relevant knowledge. In order to be flexible in the future use of custom space beatings a step closer to the foundation. Want to have like-minded friends to explore, deep inside Android, in-depth understanding of Android. First, what is Vie
