java - 从 JSON 数组中解析字符串数组

Question

我在 JSONArray ary2 中有这个；

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"
      }
      ]

我想为每个属性获取字符串数组，例如:

String[] item_id;
String[] Head_item_id; 

等无法得到它。请帮忙。

试试这个:

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");
}
