獲取json陣列資料或單個數據

單個json資料
{“state”,"1"}
獲取值的方法
JSONObject obj = new JSONObject（“放json資料，即{“state”，“1”}”）
string state = obj.getString("state")
state的值就是1
陣列json資料
<string name="json_array">
{"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}
]
}
} </string>
解析程式碼：
public void parseJsonArray(String string){
try {
JSONObject jsonObject = new JSONObject(string).getJSONObject("calendar");
JSONArray jsonArray = jsonObject.getJSONArray("calendarlist");
StringBuffer sb = new StringBuffer();
for(int i = 0;i < jsonArray.length();i ++){
JSONObject json = (JSONObject) jsonArray.opt(i);
String calendar_id = json.getString("calendar_id");
String title = json.getString("title");
String category_name = json.getString("category_name");
String showtime = json.getString("showtime");
String endshowtime = json.getString("endshowtime");
String allDay = json.getString("allDay");
sb.append("calendar_id: " + calendar_id + "\n\n" + "title: " + title + "\n\n" +
"category_name: " + category_name + "\n\n" + "showtime: " + showtime + "\n\n" +
"endshowtime: " + endshowtime + "\n\n" + "allDay: " + allDay + "\n\n" +
"-------------------------------------\n\n");
}
text.setText(sb.toString());
} catch (JSONException e) {
e.printStackTrace();
}
}
