The first time to write a blog, what to say is not difficult, on the question of generics, is a burst of learning in Jackson encountered.The following will be what I think of, meet, share out.Generics are an attribute after JDK1.5, an application of a parameter type that can be declared in a class, interface, or method, just like a local variable defined in our method, and in work we often use it in a collection object such as List,map,set, or in a class we declare ourselves.When it comes to gen

1. Preface:I also learn some basic custom view methods by referring to some custom view examples from others. Today, I reference some information, and then combined with some of my own understanding, did a one-click Erase animation. That year, I realized this is a few pictures, using frame anination way to achieve, but this method, not flexible, and resources, below, I will use a custom view method to achieve this function.2.:3.
