我希望标记在手机移动时移动,但它不会移动,直到我旋转手机,屏幕旋转,然后地图刷新,标记移动到我的实际位置,有时标记会重复,如果我旋转手机,重复的标记会消失。
知道为什么会发生这种情况吗?谢谢

当标记被复制时,您看到的实际上是系统在工作:

  • 当你第一次得到一个位置,一个标记会被添加,很酷
  • 如果一个新的位置出现,您可以调用
    handleNewLocation(location)
    并在上面添加一个新的标记:
    mMap.addMarker(camion);
  • 为了避免这种情况,请始终使用相同的标记和
    if(mCamionMarker == null){ 
        mCamionMarker = mMap.addMarker(camion);
    }else{
        mCamionMarker.setPosition(latLng);
    }
