Question

以下是我对服务器的响应，我能够获得clientproduct数组，但无法得到bulkprice数组及其json对象。我不知道是什么问题。

{"status":"success","clientproduct":[{"pid":"4","name":"kangan pair","unitprice":"1500","boxqty":"1","bulkprice":[{"minqty":"10","price":"1500"},{"minqty":"15","price":"1470"},{"minqty":"20","price":"1460"}]}]}

码

if(bxqtyy.getText().toString().trim().length() > minimum_qty.toString().equals())
                            {
                                System.out.println("NKDBKDKB");
                            }

此处代码

    if (json != null) {
                    try {
                        JSONObject jsonObj = new JSONObject(json.toString());

                        // Getting JSON Array node
                        clientproduct = jsonObj.getJSONArray(CLIENTPRODUCT_LIST);

                        // looping through All Contacts
                        for (int i = 0; i < clientproduct.length(); i++) {
                            ck = clientproduct.getJSONObject(i);

                           unitp=ck.getString("unitprice");
                            System.out.println("Unit ni price"+unitp);

                           boxq=ck.getString("boxqty");
                            System.out.println("Box ni quantity "+boxq);

                            // creating new HashMap
                            /*HashMap<String, String> map = new HashMap<String, String>();

                            map.put(BOX_QTY,c.getString(BOX_QTY));
                            clientproductdata.add(map);*/

Answer 1

我能够获得clientproduct数组但无法获取数组 bulkprice数组

bulkprice JSONArray位于JSONObject JSONArray的clientproduct内。所以使用c代替jsonObj来获取bulkprice JSONArray：

bulkprice = c.getJSONArray(BULKPRICE_LIST);

Answer 2

这是我的决定：

JSONArray big = jsonObject.getJSONArray("clientproduct");
for(int i = 0; i < big.lenght(); i++) {
    JSONArray little = big.getJSONObject(i).getJSONArray("bulkprice");
}

Answer 3

使用这些代码...它对您有所帮助....

JSONArray outer_json_array = RESPONSE.getJSONArray("clientproduct");

for(int i=0;i<outer_json_array .length();i++) {

    JSONArray inner_json_array = outer_json_array.getJSONObject(i).getJSONArray("bulkprice");

    for(int j=0;j<inner_json_array.length();j++) {
    }
}

如何在JSON数组中访问JSON数组？
