用更新的标记移除地图上的多个标记

Question

final Marker[] markerTrack = new Marker[3];
final String[] idTrack = new String[3];
public void onLocationLoaded(MarkerOptions markersReceived) {
    if(markersReceived != null) {
    /// Check if marker is implemented if yes then remove and overwrite exixting else make new array

        for(int i =0 ; i < markerTrack.length; i++){
            if(idTrack[i] == markersReceived.getTitle()){
                markerTrack[i].remove();
                markerTrack[i] = mMap.addMarker(markersReceived);

            }else{
                //make new marker
                markerTrack[i] = mMap.addMarker(markersReceived);
                idTrack[i] = markersReceived.getTitle();
            }
        }

首先，我要感谢你们所有人的努力。我最终找到了解决我的多个标记的方法，分别删除它们并更新它们。

下面是帮助我实现这一目标的逻辑

     final Marker[] markerTrack = new Marker[4];
            //final String[] idTrack = new String[3];
            final ArrayList<String> id = new ArrayList<String>();
            id.add("HELLO");
            final int[] i = {0};
 . . . .. . .
....
....
    @Override
 public void onLocationLoaded(MarkerOptions markersReceived) {
   if (markersReceived != null ) {
      if (id.contains(markersReceived.getTitle())) {
          int j = id.indexOf(markersReceived.getTitle());
           markerTrack[j].remove();
           markerTrack[j] = mMap.addMarker(markersReceived);
     } else {
           markerTrack[i[0]+1] = mMap.addMarker(markersReceived);
          id.add(markersReceived.getTitle());
           i[0]++;
      }
   }

但是伙计们，我现在遇到一个问题...那就是我的异步任务包含另一个异步方法，它需要太多的时间从Web加载结果...有什么方法可以加快这个过程...Thanx
