After analysis, there is no design process and you can do it as you think of it. I have read the "big talk design mode" before, but I can still understand it when I look at it. It is hard to understand it later, mainly because I have no experience and I have

experiments without any actual experience. Others say this is because Apple Watch is a new platform that offers an unprecedented use experience. So developers still need some time to explore and accumulate experience. In my opinion, these two reasons are reasonable. So we've summed up 5 Apple Watch design patterns that need to be circumvented to help developers get around these pits and provide the best p

This "Zen of design patterns" was not easy to get. At that time, I had the honor to ask Qin Xiaobo in the csdn forum. Reading such a classic book cannot be like reading a novel. It is intended to be a pleasure to go around for a long time. It is more about reading and changing questions. Why should we ask every key point. Teacher Qin Xiaobo's language is sometime

Chapter 4 test-driven development practices "By carefully analyzing the three steps for enterprises to run the value chain, I think it is very familiar with the test-driven development value chain of software development. The first step is to discover the value and apply it to test-driven development, that is, test first. Test-driven writingCode. The second step is production value, which is beyond doubt a stage of code writing. The third step is to reap the value. In test-driven development,

Observer patterns for Android's common design patternsThe observer design pattern is often used in Android applications, and the pattern principle is similar to this scenario:Users to book newspapers, and then in the newspaper register, the newspaper to statistics users (add users), users can also cancel the subscripti

In the past few days, we have become increasingly aware of the importance of java basics. I feel that many basic things have not been learned well. So we started the system learning of the design model. I always think that the essence of a pattern is a method. But here is a professional word. I recommend a book "learning design

Introduced Mediator mode (mediator), which encapsulates a series of object interactions with a mediation object. Intermediaries do not need to refer explicitly to each other, so that they are loosely coupled and can independently alter their interactions.
