如何在地图中平滑移动标记而不闪烁

每次我收到服务器请求以获取设备的新位置并更新地图上标记的位置时，我的标记都会出现问题，当我的车辆设备移动时，标记将跳转到新位置并闪烁。 我怎样才能避免这种情况不闪烁，或者我的标记可以顺利移动。

先感谢您。

var map;
var marker;
var markerarray =[];

setInterval(function(){

    $.ajax({
        type: "post",
        url: "vehiclecordinates.php",
        success: function(data){

            coordinates = data.latlng;
            vehiclename = data.vehiclename;

            for (var i = 0; i < coordinates.length; i++) {

                newcoordinate = new google.maps.LatLng(coordinates[i].split(",")[0],coordinates[i].split(",")[1]);
                marker =  new MarkerWithLabel({
                     map:map,
                     labelClass: "mylabels",
                     labelStyle: {opacity: 1.0},
                     labelContent: '<div>'+ vehiclename[i]+'</div>',
                     icon:{
                         //some options here
                     },
                });

                marker.setPosition(newcoordinate);
                markerarray.push(marker);
            }
        }
    });

    setTimeout(function () {
        removeMarkers();
        delete marker;
    }, 1000);
},5000);

function removeMarkers() {
    for(var i = 0; i < markerarray.length; i++) {
        markerarray[i].setMap(null);
    }
}

如果您不希望它们闪烁，请不要从地图上“删除”它们，而是更新它们的位置。

var map;
var marker;
var markerarray =[];

setInterval(function(){
  $.ajax({
    type: "post",
    url: "vehiclecordinates.php",
    success: function(data){
      coordinates = data.latlng;
      vehiclename = data.vehiclename;
      for (var i = 0; i < coordinates.length; i++) {
        newcoordinate = new google.maps.LatLng(coordinates[i].split(",")[0],coordinates[i].split(",")[1]);
        if (markerarray[vehiclename[i]] && markerarray[vehiclename[i]].setPosition){
          markerarray[vehiclename[i]].setPosition(newcoordinate);
        else {
          marker =  new MarkerWithLabel({
            map:map,
            labelClass: "mylabels",
            labelStyle: {opacity: 1.0},
            labelContent: '<div>'+ vehiclename[i]+'</div>',
            icon:{
              //some options here
            }
          });
          marker.setPosition(newcoordinate);
          markerarray[vehiclename[i]] = marker;
        }
      }
    }
  });
},5000);
