Android中的JSONObject和JSONArray解析json数据_PHP教程

String strJson = "{"students":[{"name":"Jack","age":12}, {"name":"Vista","age":23}, {"name":"Kaka","age":22}, {"name":"Hony","age":31}]}";
try {
JSONObject jo = new JSONObject(strJson);
JSONArray jsonArray = (JSONArray) jo.get("students");
for (int i = 0; i < jsonArray.length(); ++i) {
JSONObject o = (JSONObject) jsonArray.get(i);
System.out.println("name:" + o.getString("name") + "," + "age:"
+ o.getInt("age"));
}
} catch (JSONException e) {
e.printStackTrace();
}

2.使用gson中的JsonReader解析json数据

try {
String string = "{"class":1, "students":[{"name":"jack", "age":21},{"name":"kaka", "age":21},{"name":"lucy", "age":21}]}";
StringReader sr = new StringReader(string);
JsonReader jr = new JsonReader(sr);
jr.beginObject();
if (jr.nextName().contains("class")) {
System.out.println("班级: " + jr.nextString());
if (jr.nextName().equals("students")) {
jr.beginArray();
while (jr.hasNext()) {
jr.beginObject();
if (jr.nextName().equals("name"))
System.out.print("姓名：" + jr.nextString());
if (jr.nextName().equals("age")) {
System.out.println(" , 年龄：" + jr.nextInt());
}
jr.endObject();
}
jr.endArray();
}
}
jr.endObject();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
