在此代碼中，TextView 字段在傳遞給 json 時(shí)不能有任何值，并且警告是無(wú)法將 json 對(duì)象轉(zhuǎn)換為 json 數(shù)組String json = strListingsDetails; try { JSONArray jsonArray = new JSONArray(json); JSONObject jsonObject = new JSONObject(jsonArray.getJSONObject(0).toString()); JSONArray dataListArray = jsonObject.getJSONArray("DataList"); if (dataListArray != null && dataListArray.length() != 0) { for (int i = 0; i < dataListArray.length(); i++) { JSONObject jsonObject1 = dataListArray.getJSONObject(i); String listingId = jsonObject1.getString("ListingID"); String specification = jsonObject1.getString("Specifications"); String description = jsonObject1.getString("Description"); String manufacturer = jsonObject1.getString("Manufacturer"); String brand = jsonObject1.getString("Brand"); String machineType = jsonObject1.getString("ManchineType"); String condition = jsonObject1.getString("Condition"); String yearOfMfg = jsonObject1.getString("YearofMfg"); String Price=jsonObject1.getString("Price"); String ShowPrice=jsonObject1.getString("ShowPrice"); String country = jsonObject1.getString("Country"); String state = jsonObject1.getString("State"); String city = jsonObject1.getString("City"); String qty = jsonObject1.getString("Qty"); String height = jsonObject1.getString("Height"); String width = jsonObject1.getString("Width"); String length = jsonObject1.getString("Length"); String weight = jsonObject1.getString("Weight"); String warranty = jsonObject1.getString("Warranty"); String expiredOn = jsonObject1.getString("ExpiredOn");

無(wú)法將 json 對(duì)象轉(zhuǎn)換為 json 數(shù)組
您正在嘗試解析 JSON 字符串，它是 JSON 對(duì)象而不是數(shù)組
像這樣試試。
JSONObject jsonObject = new JSONObject(json);
JSONArray dataListArray = jsonObject.getJSONArray("DataList");

請(qǐng)按照我的猜測(cè)匹配您的json：
[
{
"DataList": [
{
"ListingID": "value",
"Specifications": "value",
"Description": "value",
"Manufacturer": "value",
"Brand": "value"
...
}
]
}
]
記錄你的json，你會(huì)找到答案
