如何將JSONArray轉換爲ArrayList？

我花了兩天時間思考這個問題，但未能解決。所以請幫助。如何將JSONArray轉換爲ArrayList？

這裏是我的JSON模式

{ 
    "order_room_number": "string", 
    "order_breakfast": "string", 
    "room_type_name": "string", 
    "order_number": "string", 
    "hotel_id": 0, 
    "order_check_in_time": "2017-03-09T10:56:09.343Z", 
    "order_price": "string", 
    "hotel_addres": "string", 
    "order_check_out_time": "2017-03-09T10:56:09.343Z", 
    "hotel_name": "string", 
    "order_phone": "string", 
    "order_transactionid": "string", 
    "order_date": "2017-03-09T10:56:09.343Z", 
    "user_id": 0, 
    "order_people_number": 0, 
    "order_id": 0, 
    "order_state": "string", 
    "order_number_of_room": 0, 
    "orderUserList": [ 
    { 
     "order_user_id": 0, 
     "order_user_name": "string", 
     "order_user_phone": "string", 
     "order_id": 0, 
     "order_user_id_number": "string" 
    } 
    ] 
}

這裏是我的JSON，我需要將其轉換爲ArrayList的

{ 
    "status": 200, 
    "msg": "OK", 
    "data": [ 
    { 
     "order_id": 12, 
     "order_number": null, 
     "order_transactionid": "9", 
     "order_date": null, 
     "order_check_in_time": 1488680530000, 
     "order_check_out_time": 1488680530000, 
     "order_breakfast": null, 
     "order_number_of_room": null, 
     "order_room_number": null, 
     "order_people_number": null, 
     "order_phone": null, 
     "order_price": "9", 
     "order_state": "1", 
     "room_type_name": null, 
     "hotel_name": null, 
     "hotel_addres": null, 
     "hotel_id": null, 
     "user_id": null, 
     "orderUserList": null 
    } 
    ] 
}

這裏是我的模型

package com.example.wecheatpaydemo.Model; 

/** 
* 
* 
* @Explain: 
*/ 

public class OrderUser { 


    private Long order_user_id;    // 用戶實名制裏面的姓名 
    private String order_user_name;   // 用戶實名制裏面的姓名 
    private String order_user_phone;  // 用戶的手機號，用作登錄賬號 
    private String order_user_id_number; // 用戶身份證號碼 
    private String order_id;    // 訂單表外鍵 

    public Long getOrder_user_id() { 
     return order_user_id; 
    } 

    public void setOrder_user_id(Long order_user_id) { 
     this.order_user_id = order_user_id; 
    } 

    public String getOrder_user_name() { 
     return order_user_name; 
    } 

    public void setOrder_user_name(String order_user_name) { 
     this.order_user_name = order_user_name; 
    } 

    public String getOrder_user_phone() { 
     return order_user_phone; 
    } 

    public void setOrder_user_phone(String order_user_phone) { 
     this.order_user_phone = order_user_phone; 
    } 

    public String getOrder_user_id_number() { 
     return order_user_id_number; 
    } 

    public void setOrder_user_id_number(String order_user_id_number) { 
     this.order_user_id_number = order_user_id_number; 
    } 

    public String getOrder_id() { 
     return order_id; 
    } 

    public void setOrder_id(String order_id) { 
     this.order_id = order_id; 
    } 

    @Override 
    public String toString() { 
     return "OrderUser{" + 
       "order_user_id=" + order_user_id + 
       ", order_user_name='" + order_user_name + '\'' + 
       ", order_user_phone='" + order_user_phone + '\'' + 
       ", order_user_id_number='" + order_user_id_number + '\'' + 
       ", order_id='" + order_id + '\'' + 
       '}'; 
    } 

    public OrderUser(Long order_user_id, String order_user_name, String order_user_phone, String order_user_id_number, String order_id) { 
     this.order_user_id = order_user_id; 
     this.order_user_name = order_user_name; 
     this.order_user_phone = order_user_phone; 
     this.order_user_id_number = order_user_id_number; 
     this.order_id = order_id; 
    } 

    public OrderUser() { 
    } 

}

這裏是我的碎片

public class ListChoiceone extends Fragment { 
    private RecyclerView recyclerView; 
    private List<Order> listBean; 
    private RecyclerAdapter adapter;

    } 

    private void initData() { 
     listBean = new ArrayList<>(); 



    } 

}

非常感謝你我的編碼器的朋友！

什麼** **正是在代碼不工作，你提供的？ – csmckelvey

看我的回答http://stackoverflow.com/questions/41954121/how-to-use-google-gson-to-convert-a-json-string-into-java-pojo/42039142#42039142 –

因爲我不得不隱藏服務器的接口代碼。 – 95DBC

簡單的例子：

List<Model> data = new ArrayList<>(); 

JSONArray jsonArray = jsonObject.getJSONArray("data"); 

for (int i = 0; i < jsonArray.length(); i++) { 
    data.add(new Model(/*fill your data*/)); 
}

在此先感謝 – 95DBC

謝謝你提醒我。 – 95DBC

不客氣 –

移動在此之前的for循環

ArrayList<OrderUser> listOrderUser = new ArrayList<OrderUser>();

然後，只需使用添加項目，listOrderUser.add(<your_model_item>);

和之後的for循環，做一個notifyDataSetChanged （）;在recyclerView適配器

但我不會將JSONArry轉換爲ArrayList，我如何使用 – 95DBC

添加項目謝謝您指出我的錯誤。 – 95DBC

{"myjson":[{"name":"Rajkumar","place":"Erode","gender":"male"},{"name":"Dineshkumar","place":"Erode","gender":"male"}, 
    {"name":"Saravanakumar","place":"mettur","gender":"male"} 
    {"name":"Jayakumar","place":"chennai","gender":"male"}]} 

    List<RajObj> list = new ArrayList<>(); 
    if (op!= null) { 
     int len = myjson.length(); 
     for (int i=0; i< len; i++) { 
     JSONObject o = (JSONObject) op.get(i); 
     list.add(new RajObj(o.getString('name'), o.getString('place'), o.getString('gender'))); 
     } 
    } 
    System.out.println("Result " + list.size() + " objects."); 
    public static final class RajObj { 
     final String name;

他是要求android代碼不爲php – sodhankit

嗨，你在開玩笑吧:) – 95DBC
