從JSON數組中解析字符串數組

Question

我在JSONArray ary2中有這個;

JSON字符串是：

[ 
     { 
     "item_id": "1", 
     "Head_item_id": "1", 
     "major_item_id": "1", 
     "Quantity": "10", 
     "selling_prize": "20", 
     "MRP": "90", 
     "title": "JK Lakshmi PPC Cement", 
     "SKU": "B2WBUICEM2" 
     }, 
     { 
     "item_id": "2", 
     "Head_item_id": "1", 
     "major_item_id": "1", 
     "Quantity": "10", 
     "selling_prize": "30", 
     "MRP": "80", 
     "title": "JK Lakshmi PPC Cement", 
     "SKU": "B2WBUICEM2" 
     }, 
     { 
     "item_id": "3", 
     "Head_item_id": "1", 
     "major_item_id": "1", 
     "Quantity": "10", 
     "selling_prize": "10", 
     "MRP": "70", 
     "title": "Shree Ultra OPC 43 Grade Cement", 
     "SKU": "B2WBUICEM5" 
     } 
     ] 

我想String數組爲每個屬性，如：

String[] item_id; 
String[] Head_item_id; 

等 無法得到它。請幫忙。

Answer 1

試試這個：

JSONArray arr = new JSONArray(yourJSONresponse); 
String[] item_id=new String[array.length()]; 
String[] Head_item_id=new String[arr .length()]; 
for(int i = 0; i < arr.length(); i++){ 
    item_id[i]=arr.getJSONObject(i).getString("item_id"); 
    Head_item_id[i]=arr.getJSONObject(i).getString("Head_item_id"); 
}

您需要按照下列步驟操作： - >您的JSON數據和provite getter和setter每個屬性創建POJO。使用GSON解析您的JSON數據 - >獲取所需的屬性（使用getters）並將其存儲在相應的字符串數組中
