Answer 1

最好创建一个 POJO 类

示例代码

试试这个

Create a model class like this

public class DataModel
{
    String title;
    String longitude,latitude;

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getLongitude() {
        return longitude;
    }

    public void setLongitude(String longitude) {
        this.longitude = longitude;
    }

    public String getLatitude() {
        return latitude;
    }

    public void setLatitude(String latitude) {
        this.latitude = latitude;
    }
}

比用这个

private ArrayList<DataModel> wrapall = new ArrayList<>();

private void parserJson (JSONArray jsonArray){

    try {
        JSONArray array = jsonArray;
        Log.d("jsonarrayishere", array.toString());

        for (int i = 0; i < array.length(); i++) {
            JSONObject object = array.getJSONObject(i);

            DataModel dataModel = new DataModel();

            dataModel.setTitle(object.getString("NAME"));
            dataModel.setLatitude(object.get("LATITUDE").toString());
            dataModel.setLongitude(object.get("LONGITUDE").toString());

            //Add data model to array list
            wrapall.add(dataModel);
        }
    } catch (JSONException e) {
        e.printStackTrace();
        Log.d("objectstestwrong", e.getLocalizedMessage());
    }
}

使用它从列表中检索数据

    for (int i=0;i<wrapall.size();i++){
        Log.e("NAME",wrapall.get(i).getTitle());
        Log.e("LONGITUDE",wrapall.get(i).getLongitude());
        Log.e("LATITUDE",wrapall.get(i).getLatitude());
    }
