我想知道如何通过j sons获取数据。我是这样创造但没有得到任何数据？

"arr": [1]
0:  {
"obj": {
"id": "24"
"dispensary_id": "24"
"item_name": "item 3"
"total_feedback": "1"

Answer 1

使用gson库解析JSON数据。要了解如何使用它，请使用此链接http://www.javacodegeeks.com/2011/01/android-json-parsing-gson-tutorial.html

Answer 2

你的JOSN格式错了它应该是这样的

{
    "obj": {
        "id": "24",
        "dispensary_id": "24",
        "item_name": "item 3",
        "total_feedback": "1",
        "total_item": "13",
        "followers": "7",
        "follow_status": "following",
        "category": "Edibles",
        "strain": "Indica",
        "tch": "0.70",
        "cbd": "13.30",
        "description": "testing items",
        "image": "1447508911_greenfeed-3.jpg",
        "qty1": "1/8 OZ",
        "price1": "100",
        "qty2": "1/4 OZ",
        "price2": "200",
        "qty3": "1/2 OZ",
        "price3": "400",
        "qty4": "1 OZ",
        "price4": "799",
        "dispensary_first_name": "Acme Dispensary",
        "dispensary_last_name": "Smith",
        "company": "Acme Dispensary",
        "dispensary_image": "1449182412.png",
        "city": "Irvine",
        "state": "CA",
        "status": "1"
    }
}

为此您可以检查您的json是否有效http://jsonlint.com/

用于创建json，你可以使用像

这样的库

JSONObject jsonObject = new JSONObject();
jsonObject.add("key", "value");
jsonObject.add("key", "value");
