Intermittent, "Android source code design mode analysis" also read, the book mentions a lot of design patterns, but some in the development of the odds are very small, so can not master nor too much influence. I think the maximum value of this book is two points, one is from the point of view of design mode to understand the

window is an abstract class, the implementation class is PhonewindowNo12:CreateView is relatively simple, if there is a prefix, then constructs the full path of the view, loads the class into the virtual machine, obtains the constructor of the class and caches it, creates the view object through the constructor, and finally returns the View object, which is The process of parsing a single view .

These services are stored in a hashmap in the form of key-value pairs, where the user simply acquires the corresponding servicefetcher based on key, and then obtains the specific service object through the GetService function of the Servicefetcher object. When first fetched, the Servicefetcher's Creatservice function is called to create the service object, and then the object is cached in a list, fetched directly from the cache t
