android 解析json数据格式

json数据格式解析我自己分为两种；
一种是普通的，一种是带有数组形式的；
普通形式的：
服务器端返回的json数据格式如下：
{"userbean":{"Uid":"100196","Showname":"\u75af\u72c2\u7684\u7334\u5b50","Avtar":null,"State":1}}
分析代码如下：
// TODO 状态处理 500 200
带数组形式的：
服务器端返回的数据格式为：
{"calendar":
{"calendarlist":
[
{"calendar_id":"1705","title":"(\u4eb2\u5b50)ddssd","category_name":"\u9ed8\u8ba4\u5206\u7c7b","showtime":"1288927800","endshowtime":"1288931400","allDay":false},
{"calendar_id":"1706","title":"(\u65c5\u884c)","category_name":"\u9ed8\u8ba4\u5206\u7c7b","showtime":"1288933200","endshowtime":"1288936800","allDay":false}
]
}
}
分析代码如下：
返回数组，且其中标签名字不确定的
服务器端返回数据格式：

解析代码：
try {

List<UserProject> userProjectsList = new ArrayList<UserProject>();
JSONObject jsonObject = new JSONObject(jsonStr);
JSONObject todoObject = (JSONObject) jsonObject
.optJSONObject("todoList");
JSONArray projectArray = jsonObject.getJSONArray("projectList");
if (todoObject != null) {
JSONArray todoArray = todoObject.names();
for (int i = 0; i < todoArray.length(); i++) {
JSONArray userTodos = todoObject.optJSONArray(todoArray
.getString(i));
for (int j = 0; j < userTodos.length(); j++) {
JSONObject userTodo = userTodos.optJSONObject(j);
UserTodo todo = new UserTodo();
todo.setId(userTodo.optInt(UserTodo.FIELD_ID));
todo.setTitle(userTodo.optString(UserTodo.FIELD_TITLE));
userTodosList.add(todo);
}
}
}
TDUserTodoDao userTodoDao = new TDUserTodoDao(context);
userTodoDao.deleteAll();
userTodoDao.addAll(userTodosList);
for (int i = 0; i < projectArray.length(); i++) {
JSONObject userProject = (JSONObject) projectArray.opt(i);
UserProject project = new UserProject();

}
TDUserProjectDao userProjectDao = new TDUserProjectDao(context);
userProjectDao.deleteAll();

} catch (JSONException e) {

}该例子只解析了部分需要的属性。
