JSONObject无法转换为Android中的JSONArray

-1

我是android开发中的新手。我面临的一个错误，如： - JSON对象不能在jsonArray被转换： -JSONObject无法转换为Android中的JSONArray

我ProductInner.java：

public class ProductInner extends AppCompatActivity { 

TextView textView; 
ImageView imageView; 
LinearLayout linearLayout; 
String s,s1; 
List<String> mainImage = new ArrayList<>(); 
List<String> outerlist = new ArrayList<>(); 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.product_inner); 

    textView = (TextView)findViewById(R.id.product_inner_page_product_name); 
    imageView = (ImageView)findViewById(R.id.product_inner_page_product_main_image); 
    linearLayout = (LinearLayout)findViewById(R.id.sub_images_show_section); 

    new ProductInnerDisplay().execute("http://opencart.codeniques.com/shopping/?route=feed/web_api/product&id=80&key=test123$"); 
} 

public class ProductInnerDisplay extends AsyncTask<String,Void,Void>{

My Json Array Link is here

我的logcat显示此错误： -

E/Error: Value {"id":"80","name":"Bag_80","model":"
","reward":"0","points":"0","image":"http://opencart.codeniques.com/shopping/image/cache/data/product/bag_81_1-1000x1000.JPG","images":["http://opencart.codeniques.com/shopping/image/cache/data/product/bag_80_2-80x80.JPG"],"price":1175,"minimum":"1","newprice":1163.25,"qty":4,"rating":0,"description":""} at productdata of type org.json.JSONObject cannot be converted to JSONArray`

你能告诉堆栈跟踪？ – erosb

JSON中的productdata'键在哪里？ –

第二个数组名称是产品数据 –

productdata不是JSONArray而是一个JSONObject，所以你必须改变

JSONArray jsonArray1 = jsonObject.getJSONArray("productdata");

到

JSONObject jsonObject1 = jsonObject.getJSONObjct("productdata");

我发现我的错误非常感谢@Maloubobola –

不客气;） – ThomasThiebaud

如日志：

productdata of type org.json.JSONObject cannot be converted to JSONArray

意味着productdata密钥用于JSONObject响应服务器json而不是JSONArray。

因此，获得productdata关键值的JSONObject代替JSONArray：

JSONObject jsonObject1 = jsonObject.getJSONObject("productdata");

您正在将productData作为JSONArray获取，而它是JsonObje CT其中包含图像的JsonArray我可以在JSON链接看到您提供

JSONArray jsonArray1 = jsonObject.getJSONArray("productdata");

该行代码应该是一个JSONObject
