Template mode I think in the development of Android is the longest use, basically is ubiquitous, know this mode, help us to the Android source code and framework have a deeper understanding. What is template mode, template mode is

Adapter mode is an important design pattern and has been widely used in Android. Adapters are similar to the plugs in the real world, and through adapters we can combine two different types of data that are classified into different classes without having to add or modify the methods in the class according to a need. The adapter is divided into one-way adapters and two-way adapters, which are used more fre

This pattern is relatively independent of several other modes, it is only responsible for controlling its own instantiation quantity single (instead of considering what kind of instance produces for the user), it is very interesting, it is a very clean mode, I like this mode
