The open source framework citypickerview is used in Android to realize the three-level linkage selection of provinces and cities

1. General

I remember when I was working on the mall project, I needed to realize the three-level linkage between provinces and cities in the address selection to facilitate users to fill in the address quickly. At that time, I used an open-source control called Android wheel. At that time, I felt very easy to use. The only trouble was that I needed to sort out and parse the XML files of provinces and cities. The idea was very simple, but the amount of code was relatively large. I found another open source component accidentally, that is, the city picker view to be introduced today.
