json生成与解析示例

json是移动平台上十分常用的数据传输格式,本示例提供了两种Json格式文件生成与解析的方法。第一种通过JsonReader和JsonWriter两个对象进行json文件的读写操作,需求sdk在11以上。第二种通过JSONArray、JSONObject、JSONTokener等对象进行json读写操作,需求sdk在9以上。这种方法也可通过引进jar包的方法在其他版本的sdk中实现。启动客户端后,先点击注入json按钮(第1或3个按钮)生成Json文件(方位为sdcard根目录下的cdjson.json),再点击读取json按钮(第2或4个按钮)。实例中的JsonParserUtil类对应第一种解析方法,JsonParserUtil2类对应第二种解析方法本资料共包括以下附件:

(Json is a very common data transmission format on mobile platforms. This example provides two methods for generating and parsing Json format files. The first is to read and write the json file through the JsonReader and JsonWriter objects. The sdk must be above 11. The second method uses JSONArray, JSONObject, JSONTokener and other objects to perform json read and write operations. The sdk is required to be above 9. This method can also be implemented in other versions of sdk by introducing jar packages. After starting the client, click the Inject json button (the first or third button) to generate a Json file (the orientation is cdjson. json in the root directory of the sdcard), and then click the Read json button (the second or fourth button). The JsonParserUtil2 class in the example corresponds to the first parsing method, and the JsonParserUtil class 2 corresponds to the second parsing method.
