Question

我有一个包含另一个数组的Json数组。我想获取第二个array.ie的数据：以我的情况为“材料代码”。如果我再问一次，请原谅我。

我的Json

{
"Result": true,
"Records": {
    "ID": "37e33c9e",
    "RRNo": "RR301",
    "Title": "rightnow",
    "RRDate": "2018-06-27T00:00:00",
    "RRForCompany": "A",
    "RRStatus": "Open",
    "RRDetailList": [{
        "ID": "dff49a5a",
        "RRID": "37e33c9e",
        "MaterialID": "b4378594",
        "Description": "Pol",
        "ExtendedDescription": "hello",
        "CurrStock": "10",
        "ApRate": 2000.00,
        "RequestedQty": "8100",
        "RRMaterialObj": {
            "ID": "b4378594",
            "MaterialCode": "R101",
            "ApRate": 0.0,
        }
    }],
    "CompanyObj": null,
    "CommonObj": {

    },
    "RRFormatted": "27-Jun-2018",

}

}

我做了什么

                ArrayList<String[]> dataArrayList=new ArrayList<>();
                JSONArray jsonObject1= records.getJSONArray("RRDetailList");

                for (int i = 0; i < jsonObject1.length(); i++) {
                    JSONObject jsonObject2 = jsonObject1.getJSONObject(i);
                    String[] data = new String[6];
                    data[0] = jsonObject2.getString("ID");
                    data[1] = jsonObject2.getString("Description");
                    data[2] = jsonObject2.getString("RequestedQty");
                    data[3] = jsonObject2.getString("CurrStock");
                    data[4] = jsonObject2.getString("ApRate");

                    JSONArray jsonObject3 = records.getJSONArray("RRMaterialObj"); 
                    for(int j=0;j<jsonObject3.length();j++){
                        JSONObject jsonObject5= jsonObject3.getJSONObject(j);
                        data[5] =jsonObject5.getString("MaterialCode");
                    }
                    dataArrayList.add(data);
                }

帮帮我。我是新手，还是Android。

Answer 1

records.getJSONArray("RRMaterialObj")

更改为
`jsonObject2.getJSONObject("RRMaterialObj");`

 JSONObject jsonObject3 = jsonObject2.getJSONArray("RRMaterialObj"); 

 data[5] =jsonObject3.getString("MaterialCode");

在jsonarray中获取数据
