标记轨道运动图标

Question

获取一个gps数组，在地图polilayn上绘制。然而，对于某些坐标插入方向，但图标并不总是插入，应该有“边距”

如何插入图标以使其位于polilayn线上？

 void addTraclMarker(double locationA,double locationB, int drawable,
       String carnames, String carspeeds)
 {     
    Marker startMarker = new Marker(mapView);
    startMarker.setPosition(new GeoPoint(locationA,locationB));     
    startMarker.setIcon(getResources().getDrawable(drawable));      
    startMarker.setTitle("jkdfghspdifj");       
    startMarker.setAnchor(Marker.ANCHOR_CENTER, 1.0f);      
    MarkerInfoWindow infoWindow = new  MyInfoWindow(R.layout.bonuspack_bubble, 
            mapView,carnames,carspeeds,"","");      
    startMarker.setInfoWindow(infoWindow);      
    mapView.getOverlays().add(startMarker);
 }

Answer 1

startMarker.setAnchor(Marker.ANCHOR_CENTER, Marker.ANCHOR_CENTER);

查看Marker#setAnchor以了解其工作原理。
