Android 谷歌地图滚动速度慢，手机应用程序在尝试显示50标记时显示ANR

嗨，我试图在谷歌地图上显示100个标记，但当我们在地图上渲染标记时。谷歌地图滚动停止和应用程序显示ANR。 下面是我在地图上显示标记的代码。 此外，API使用服务每隔5秒调用一次

请告诉我我们做错了什么

 if (getWorkerSummaryListResponse.getErrorCode() == 0) {
                workerListList = getWorkerSummaryListResponse.getWorkerListList();
                Log.d(TAG, "setData: " + workerListList.toString());


                for (user.WorkerSummary workerBasicInfo : workerListList) {
                    userPosition = workerBasicInfo.getUserPosition();
                    workerAlarmStatus.get(workerBasicInfo.getUserAlarmStatus());
                    if (workerBasicInfo.getWorkerActiveStatus() == 1) {
                        if (!userPosition.toString().equalsIgnoreCase("")) {
                            if (!mOnlineWorkerList.contains(workerBasicInfo)) {
                                mOnlineWorkerList.add(workerBasicInfo);
                            }
                            userPosition.getGpsData().getLat();
                            userPosition.getGpsData().getLng();
                            markerOptions = new MarkerOptions();
                            markerOptions.icon(icon);
                            markerOptions.position(new LatLng(userPosition.getGpsData().getLat(), userPosition.getGpsData().getLng()));
                            markerOptions.title(workerBasicInfo.getWorkerInfo().getEmail());
                            //  mMap.animateCamera(CameraUpdateFactory.newLatLng(new LatLng(userPosition.getGpsData().getLat(), userPosition.getGpsData().getLng())));
                            // mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(userPosition.getGpsData().getLat(), userPosition.getGpsData().getLng()), 12.0f));//where 14.0 is the zoom level
                            marker = mMap.addMarker(markerOptions);
                            marker.setTag(workerBasicInfo);
                        }

                    }
                }
