Recently, when learning the picture loading frame glide, he was shocked by his streamlined wording. In a word, it can be done.Glide.with (mcontext). load (URL) . Centercrop () . Placeholder (r.drawable.default_img) . Crossfade ( ) . into (Mimageview); At the same time at the beginning of the year, when learning Rxjava, with a chain-style programming is very elegant.

First, the builder model(Builder)The factory class pattern provides the pattern of creating a single class, while the builder pattern is to centralize the various products to manage, to create composite objects, so-called composite objects that refer to a class that has different properties, in fact the builder pattern
Problems to solve:
The object I created is more complex, and the member functions inside the object represent different instances with different implementations, in other words, the same object-building process can have different representations. For example, I went to eat crossing that day, they have different packages, the package contains the same kind of, have a bowl of rice noodles, a cold dish, a drink. But the 3 of different packages are not all the same. At this point, we can use the

The build pattern is the object's creation pattern. The construction pattern separates the internal representation of a product from the product's generation process, thus enabling a build process to produce a product
Transferred from: http://www.cnblogs.com/moonz-wu/archive/2011/01/11/1932473.htmlThe builder pattern is defined in design mode as a pattern for building complex objects that often require multiple-step initialization or assignment to complete. So, in the actual development process, where do we fit the builder model? It is a good practice to use builder mode inste

[Mode overview] ---------- by xingooPattern intent
The creation of an object is very complex. In order to distinguish the building process from the use process, it is separated. A ctor class is used to create objects. Builder specifies the creation process.Mode Structure
Builder abstracts the builder interface and standardizes the construction of each component.

Make a little progress every day and be happy every day. I insist on writing something every day. I feel very good. I can review basic knowledge and gain a sense of accomplishment. Why not? The design pattern is something a cainiao must master to become a master. Therefore, today's topic is the builder pattern of t
The builder pattern, in fact, is to abstract the creation process of complex objects and to produce different objects for different creation processes.The builder hides the production process of the product, which is the process of producing the product, and if it changes the internal representation of the product, it is only possible to define a concrete builder.The UML diagram is given below: Here we use

In the design mode, the builder mode is defined as a mode for building complex objects. The constructed objects often need to be initialized or assigned values in multiple steps. So, in the actual development process, where do we use the builder mode? It is a good practice to use the builder mode to replace the multi-parameter constructor.
We often have to writ

Overview: Separating the construction of a complex object from its representation so that the same build process can create different representations
Advantages:
The builder pattern separates the implementation of an object from the associated ' business ' logic, making it easy to add (or change) implementations without changing the logic of the event.
Disadvantages:
