Android secondary encapsulation based on okhttputils network request

Why is okhttputils network request encapsulated twice?

1. Reduce the amount of code. 2. It is convenient to change the network processing framework later

Implementation principle of secondary packaging

1. Extract the network request into a method. 2. The variable parameters inside can be passed through the parameter or a set method. 3. For request failure and success, we can use interface callback to let the object calling the method process

Function of encapsulated network processing class

1. Network request 2. Convert XML data into JavaBean

Each listview that handles network requests must process 3 data methods

1. Initialization data 2. Pull-down refresh data 3. Pull-up load data
