Question

我有JsonObject

我有返回JSONArray的方法。我想传递第一个字段并只获取数据数组。然后将其转换为我的阵列列表。我会非常感谢您的任何建议。

  void getUsersBeacons(){
    type = new TypeToken<List<Beacon>>(){}.getType();
    JSONArray myReq = new JSONArray(Request.Method.GET, Url + testId + Url2, new Response.Listener<JSONArray>() {
        @Override
        public void onResponse(JSONArray response) {
            try{
            JSONArray buffArray = response.getJSONArray(2);
               JSONArray bufJsonArray = response.getJSONArray(1);
                beaconsList = converter.fromJson(bufJsonArray.toString(), type);
            }catch (Exception e){
                e.printStackTrace();
            }
        }


    });
    VolleySingleton.getInstance(getActivity().getApplicationContext()).addToRequestQueue(myReq);
}

Beacon课程：

public class Beacon {

private Object idBeacon;
private String friendlyName;
private String imageUrl;

public Beacon(Object idBeacon, String friendlyName, String imageUrl) {
    this.idBeacon = idBeacon;
    this.friendlyName = friendlyName;
    this.imageUrl = imageUrl;
}

public Object getIdBeacon() {
    return idBeacon;
}

public void setIdBeacon(Object idBeacon) {
    this.idBeacon = idBeacon;
}

public String getFriendlyName() {
    return friendlyName;
}

public void setFriendlyName(String friendlyName) {
    this.friendlyName = friendlyName;
}

public String getImageUrl() {
    return imageUrl;
}

public void setImageUrl(String imageUrl) {
    this.imageUrl = imageUrl;
}

}

如果我理解正确，你最好传入JSONArray而不是字符串并解析它的内容，如下所示：

internal = TRUE

UPD：在回复您的评论时，您必须使用finalModel代替public static List<Beacon> fromJson(JSONArray array) { ArrayList<Beacon> res = new ArrayList<>(); for (int i = 0; i < array.length(); ++i) { JSONObject beacon = array.getJSONObject(i); res.add(new Beacon(beacon.getInt("beaconId"), beacon.getString("name"), beacon.getString("imageUrl")))); } return res; }，然后执行此操作：

Response.Listener<JSONObject>

Android Volley将JSONArray转换为ArrayList <myobject>
