Example code for JSON data parsing in Android

Parsing JSON data in Android

In Android network programming, JSON is a more widely used data transmission mechanism than XML. In many HTTP network requests or interface calls, many of the returned are JSON. Therefore, learning to parse JSON is a basic skill for learning Android.

JSON is a lightweight text data exchange format, which is independent of language and platform. Smaller, faster, and easier to parse than XML. JSON uses key value pairs to store data. JSON saves values that can be numbers, strings, Booleans, arrays, and objects.

Cut the crap and go straight to the code. The following Josn is parsed:

In this experiment, the JSON is saved as a language. JSON file and placed in the assets folder. In actual project development, JSON is generally returned by the server after HTTP request. The specific implementation code is as follows:

After the program runs, the screenshot is as follows:

So far, the parsing of JSON string has been completed successfully. My personal understanding of XML parsing and JSON parsing is like peeling onions, parsing layer by layer. As long as I understand the logical relationship, there will be no problem. Sometimes JSON will encounter 3-layer and 4-layer circular nesting, which will be more troublesome. As long as you follow the steps, there will be no error.
