Java Android仅JSON对象通过迭代获取

我有一个只包含对象的json文件，现在我无法通过迭代获取所有对象，因为这里没有数组

下面是我在android studio中尝试的代码&JSon数据截图

您仍然可以迭代：

for (Iterator key=jsonObjectchild.keys();key.hasNext();) {
    JSONObject flatName = json.get(key.next());
    ...
}

这是一个完整的例子。对我有用

HttpURLConnection connection = null;
try {
    URL url = new URL("https://api.myjson.com/bins/r7dj6");
    connection = (HttpURLConnection) url.openConnection();
    connection.connect();
    InputStream inputStream = connection.getInputStream();

    BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
    String line;
    StringBuilder stringBuffer = new StringBuilder();
    while ((line = reader.readLine()) != null){
        stringBuffer.append(line);
    }

    JSONObject jsonObject = new JSONObject(stringBuffer.toString());
    JSONObject apartmentObject = jsonObject.getJSONObject("Apartment");
    Iterator<String> keys = apartmentObject.keys();
    while (keys.hasNext()) {
        String flatName = keys.next();
        JSONObject flat = apartmentObject.getJSONObject(flatName);
        String age = flat.getString("age");
        String color = flat.getString("color");
        String name = flat.getString("name");
        String owner = flat.getString("owner");
        String partner = flat.getString("partner");
        Log.d("Flat", flatName + ": " + age + ", " + color + ", " + name + ", " + owner + ", " + partner);
    }
} catch (Exception e) {
    e.printStackTrace();
} finally {
    if (connection != null) {
        connection.disconnect();
    }
}

HttpURLConnection=null；
试一试{
URL=新URL（“https://api.myjson.com/bins/r7dj6");
connection=（HttpURLConnection）url.openConnection（）；
connection.connect（）；
InputStream InputStream=connection.getInputStream（）；
BufferedReader reader=新的BufferedReader（新的InputStreamReader（inputStream））；
弦线；
StringBuilder stringBuffer=新的StringBuilder（）；
而（（line=reader.readLine（））！=null）{
stringBuffer.append（行）；
}
JSONObject JSONObject=newJSONObject（stringBuffer.toString（））；
JSONObject apartmentObject=JSONObject.getJSONObject（“公寓”）；
迭代器keys=apartmentObject.keys（）；
while（keys.hasNext（））{
字符串flatName=keys.next（）；
JSONObject flat=apartmentObject.getJSONObject（flatName）；
String age=flat.getString（“age”）；
String color=flat.getString（“color”）；
String name=flat.getString（“name”）；
字符串所有者=flat.getString（“所有者”）；
String partner=flat.getString（“partner”）；
Log.d（“平面”，平面名称+”：“+age+”、“+color+”、“+name+”、“+owner+”、“+partner”）；
}
}捕获（例外e）{
e、 printStackTrace（）；
}最后{
if（连接！=null）{
连接断开（）；
}
}

for（迭代器key=jsonObjectchild.keys（）；key.hasNext（）；）{JSONObject flatName=jsonObjectchild.getJSONObject（String.valueOf（key））；String name=flatName.getString（“name”）；String color=flatName.getString（“color”）；}我试着这么做，但没有wokring@Tasnuvaoshin字符串.valueOf（）中缺少key.next（）

HttpURLConnection connection = null;
try {
    URL url = new URL("https://api.myjson.com/bins/r7dj6");
    connection = (HttpURLConnection) url.openConnection();
    connection.connect();
    InputStream inputStream = connection.getInputStream();

    BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
    String line;
    StringBuilder stringBuffer = new StringBuilder();
    while ((line = reader.readLine()) != null){
        stringBuffer.append(line);
    }

    JSONObject jsonObject = new JSONObject(stringBuffer.toString());
    JSONObject apartmentObject = jsonObject.getJSONObject("Apartment");
    Iterator<String> keys = apartmentObject.keys();
    while (keys.hasNext()) {
        String flatName = keys.next();
        JSONObject flat = apartmentObject.getJSONObject(flatName);
        String age = flat.getString("age");
        String color = flat.getString("color");
        String name = flat.getString("name");
        String owner = flat.getString("owner");
        String partner = flat.getString("partner");
        Log.d("Flat", flatName + ": " + age + ", " + color + ", " + name + ", " + owner + ", " + partner);
    }
} catch (Exception e) {
    e.printStackTrace();
} finally {
    if (connection != null) {
        connection.disconnect();
    }
}
