java - JSON 数组问题

Question

嘿!

我有一个包含电视 channel 的 JSON 数组，数组的长度为 3，但传输到树形图后，值只有 1。

请帮忙

代码:

try
            {

                JSONObject menuobj = this.getJSONObject("responseData");
                Log.e("XXX", menuobj.toString());
                JSONArray array = menuobj.getJSONArray("countries");
                TreeMap<String, Integer> map = new TreeMap<String, Integer>();
                for (int i = 0; i < array.length(); i++)
                {
                    JSONObject obj = new JSONObject();
                    obj = array.getJSONObject(i);
                    if (obj.getString("name").equals(country))
                    {
                        Log.e("XXX2", obj.toString());
                        JSONArray arr = obj.getJSONArray("channels");
                        Log.e("XXX3", String.valueOf(arr.length()));
                        for (int j = 0; j < arr.length(); j++)
                        {
                            JSONObject obj2 = new JSONObject();
                            obj2 = arr.getJSONObject(i);
                            map.put(obj2.getString("name"), obj2.getInt("id"));
                        }
                        Log.e("XXX4", String.valueOf(map.size()));
                        return map;
                    }


                }

我相信:

obj2 = arr.getJSONObject(i);

应该是

obj2 = arr.getJSONObject(j);

因此，您将三倍相同的键/值对象对放入映射中。
