arcgis版本：arcgis-android:100.0.0

加载在线地图：
1.是使用ArcGISMapImageLayer加载，以图片形式加载整个地图，适合大数据量加载

ArcGISMapImageLayer layer = new ArcGISMapImageLayer(Url);//url为在线图层的网址
// layer.setName("名字");可以设置图层的名字
layer.addLoadStatusChangedListener(new LoadStatusChangedListener() {
                                    @Override
                                    public void loadStatusChanged(LoadStatusChangedEvent loadStatusChangedEvent) {
                                        if (loadStatusChangedEvent.getNewLoadStatus()==LoadStatus.LOADED){
                                        }
                                    }
                                });//监听图层加载的状态，当loaded时，图层加载好了
 MapView mainMapView = (MapView) findViewById(R.id.mapView);
LayerList mainLayerList = mainMapView.getMap().getOperationalLayers();
mainLayerList .add(layer);

2.使用FeatureLayer加载图层，适合数量小的图层

ServiceFeatureTable mainServiceFeatureTable = new ServiceFeatureTable(url);//url为在线图层网址
mainServiceFeatureTable.setFeatureRequestMode(ServiceFeatureTable.FeatureRequestMode.ON_INTERACTION_NO_CACHE);
 mainServiceFeatureTable.addLoadStatusChangedListener(new LoadStatusChangedListener() {
                                    @Override
                                    public void loadStatusChanged(LoadStatusChangedEvent loadStatusChangedEvent) {
                                        String a = loadStatusChangedEvent.getNewLoadStatus().toString();
                                        if (loadStatusChangedEvent.getNewLoadStatus() == LoadStatus.LOADED) {
                                           
                                        }
                                    }
                                });
FeatureLayer mainFeatureLayer = new FeatureLayer(mainServiceFeatureTable);
MapView mainMapView = (MapView) findViewById(R.id.mapView);
LayerList mainLayerList = mainMapView.getMap().getOperationalLayers();
 mainLayerList.add(mainFeatureLayer);
