安卓版本（未測(cè)）

http://repo1.maven.org/maven2/com/alibaba/fastjson/1.1.51.android/

<dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.28</version> </dependency>

2.1.1 解析JSON對(duì)象

String jsonData="{\n" +" \"code\":200,\n" +" \"msg\":\"success\",\n" +" \"data\":{\n" +" \"name\":\"導(dǎo)演\",\n" +" \"age\":20,\n" +" \"sex\":\"girl\"\n" +" }\n" +"}"; //先把String對(duì)象轉(zhuǎn)換成json對(duì)象 JSONObject object= JSONObject.parseObject(jsonData);System.out.println(object.get("code")); System.out.println(object.getJSONObject("data").get("name")); System.out.println(object.getJSONObject("data").get("age")); System.out.println(object.getJSONObject("data").get("sex"));

2.1.2 解析JSON對(duì)象數(shù)組

String jsonData="{\n" +" \"code\":200,\n" +" \"msg\":\"success\",\n" +" \"data\":[\n" +" {\n" +" \"name\":\"導(dǎo)演\",\n" +" \"age\":20,\n" +" \"sex\":\"girl\"\n" +" },{\n" +" \"name\":\"灰太狼\",\n" +" \"age\":21,\n" +" \"sex\":\"boy\"\n" +" },{\n" +" \"name\":\"有勇氣的牛排\",\n" +" \"age\":19,\n" +" \"sex\":\"girl\"\n" +" }\n" +" ]\n" +"}"; //先把String對(duì)象轉(zhuǎn)換成json對(duì)象 JSONObject object= JSONObject.parseObject(jsonData);List<HashMap> list =JSON.parseArray((object.get("data")).toString(), HashMap.class); for(int i=0;i<list.size();i++){System.out.println(list.get(i).get("name"));; }
