Answer 1

替换

JSONObject json = new JSONObject(result);
JSONArray jArray = json.getJSONArray("name");

这两行由

JSONArray jArray = new JSONArray(result);

也改变

country.setId(jObject.getString("id"));

country.setId(jObject.getInt("id") + "");

[
    {
        "id": ​1,
        "name": "Vietnam"
    },
    {
        "id": ​2,
        "name": "China"
    },
    {
        "id": ​3,
        "name": "USA"
    },
    {
        "id": ​4,
        "name": "England"
    },
    {
        "id": ​10,
        "name": "Russia"
    }
]

@Override
protected String doInBackground(Void... params) {

    // call load JSON from url method
    if(loadJSON(this.url) != null) {
        return loadJSON(this.url).toString();
    }
    Log.d("LoadJSONFromUrl", "Failed to get JSONObject.");
    return null;
}
