Android 创建 JSON 对象的 JSON 数组

您好，有谁知道如何创建一个包含对象的数组，每个对象中都包含多个对象？我似乎无法理解它

结构应该是这样的

Array{[object]{subobject,subobject}
      [object]{subobject,subobject}
     }

这是我到目前为止所拥有的

JSONObject obj = new JSONObject(json2);    
            JSONObject objData = obj.getJSONObject("data");
            fixturesArray = objData.getJSONArray("fixtures");

            JSONArray FixArray = new JSONArray();


            for(int t = 0; t < fixturesArray.length(); t++){
            JSONObject fixObj = fixturesArray.getJSONObject(t);
            String Matchdate = fixObj.getString("matchdate");
            JSONObject DateObj = DateObj.put(Matchdate, DateObj);

这是我的 JSON 本质上是我所拥有的，如果是我需要将它们排序到日期数组中的固定装置的提要

{
    "code":200,
    "error":null,
    "data":{
        "fixtures":[
            {
                "kickoff":"15:00:00",
                "matchdate":"2012-07-28",
                "homescore":null,
                "awayscore":null,
                "attendance":null,
                "homepens":null,
                "awaypens":null,
                "division_id":"5059",
                "division":"Testing 1",
                "comp":"LGE",
                "location":null,
                "fixture_note":null,
                "hometeam_id":"64930",
                "hometeam":"Team 1",
                "awayteam_id":"64931",
                "awayteam":"Team 2"
            }, {
                "kickoff":"15:00:00",
                "matchdate":"2012-07-28",
                "homescore":null,
                "awayscore":null,
                "attendance":null,
                "homepens":null,
                "awaypens":null,
                "division_id":"5059",
                "division":"Testing 1",
                "comp":"LGE",
                "location":null,
                "fixture_note":null,
                "hometeam_id":"64930",
                "hometeam":"Team 1",
                "awayteam_id":"64931",
                "awayteam":"Team 2"
            }
        ]
    }
}

你是这个意思吗？：

JSONObject obj = new JSONObject();
obj.put("x", "1");
JSONObject parent_object = new JSONObject();
parent_object.put("child", obj);
JSONArray array = new JSONArray(parent_object.toString());
