您好，我正在开发一个车辆跟踪应用程序。对于实时跟踪，我们使用webservices.My问题是我只从webservice获得最后一个值，而且还在重复。我没有得到其他值。这是我的代码。请帮我提前致谢

Answer 1

您正在将元素添加到arraylist而不清除LiveTrackArrayList.add(vdetails);

通过在forloop

上方使用LiveTrackArrayList添加之前清除LiveTrackArrayList.clear();

  JSONArray array = object.getJSONArray("data");
here >  LiveTrackArrayList.clear();
    for (int i = 0; i < array.length(); i++) {

来自webservice的价值正在重复
