创建JSON android

我想要这样的输出

{"content":{
     "A":["a1","a2","a3"],
     "B":"b1String",
     "C":["c1","c2"]}}

到现在为止，我得到了这个

{"content":{
     "A":"[a1, a2, a3]",
     "C":"[c1, c2]",
     "B":"b1String"}}

下面是我的代码

Map <String, Object> myMap =  new HashMap<String, Object>();

myMap.put("A",arrayOfA); //which is ArrayList<String>
myMap.put("B", myB1String);//which is String
myMap.put("C", arrayOfC);//which is ArrayList<String>

JSONObject jsonAll = new JSONObject(myMap);

Map <String, Object> mapAll =  new HashMap<String, Object>();
mapAll.put("content", jsonAll);

JSONObject finalObject=new JSONObject(mapAll);
Log.e("JSON", finalObject.toString());

Map myMap=newhashmap（）；
myMap.put（“A”，arrayOfA）//哪个是ArrayList
myMap.put（“B”，myB1String）//哪个是字符串
myMap.put（“C”，arrayOfC）//哪个是ArrayList
JSONObject jsonAll=新的JSONObject（myMap）；
Map mapAll=新的HashMap（）；
mapAll.put（“内容”，JSONAL）；
JSONObject finalObject=新的JSONObject（mapAll）；
Log.e（“JSON”，finalObject.toString（））；

任何帮助都将不胜感激。谢谢

如果您想在

数组中显示它

，那么您需要在

JSONArray

中添加所有字符串数组，并将其添加到对象中以将其显示为数组

示例：

    JSONArray s2 = new JSONArray();
    s2.put("a1");
    s2.put("a2");
    s2.put("a3");

    myMap.put("A",s2); //which is ArrayList<String>
    myMap.put("B", "b1String");//which is String
    myMap.put("C", s2);

    //which is ArrayList<String>

    JSONObject jsonAll = new JSONObject(myMap);

    Map <String, Object> mapAll =  new HashMap<String, Object>();
    mapAll.put("content", jsonAll);

    JSONObject finalObject=new JSONObject(mapAll);
    Log.d("JSON", finalObject.toString());

{"content":{"A":["a1","a2","a3"],"B":"b1String","C":["a1","a2","a3"]}}

试试这种方法，希望这能帮助你解决问题。

String[] stringArrayOfA = new String[]{"a1","a2","a3"};
String[] stringArrayOfC = new String[]{"c1","c2"};

try {
    JSONArray jsonArrayA = new JSONArray();
    for (String str : stringArrayOfA){
        jsonArrayA.put(str);
    }
    JSONArray jsonArrayC = new JSONArray();
    for (String str : stringArrayOfC){
        jsonArrayC.put(str);
    }
    JSONObject innerJsonobject = new JSONObject();
    innerJsonobject.put("A",jsonArrayA);
    innerJsonobject.put("B","b1String");
    innerJsonobject.put("C",jsonArrayC);
    JSONObject outerJsonObject = new JSONObject();
    outerJsonObject.put("content",innerJsonobject);
    Log.e("JSON", outerJsonObject.toString());
} catch (JSONException e) {
    e.printStackTrace();
}

Result :{"content":{"A":["a1","a2","a3"],"B":"b1String","C":["c1","c2"]}}
