1.ArcGISTiledMapServiceLayer:网络切片图层


    /**
     * 添加切片图层
     */
    private void addTileServiceLayer() {
        String netLayerUrl = "http://services.arcgisonline.com/arcgis/rest/services/World_Street_Map/MapServer";
        ArcGISTiledMapServiceLayer arcGISTiledMapServiceLayer = new ArcGISTiledMapServiceLayer(netLayerUrl);
        mMapView.addLayer(arcGISTiledMapServiceLayer);

        arcGISTiledMapServiceLayer.setOnStatusChangedListener(new OnStatusChangedListener() {
            @Override
            public void onStatusChanged(Object o, STATUS status) {
                if (status == STATUS.INITIALIZED) {
                    Log.e("xyh", "加载成功");
                } else if (status == STATUS.INITIALIZATION_FAILED || status == STATUS.LAYER_LOADING_FAILED) {
                    Log.i("xyh", "加载失败");
                }
            }
        });
    }

2.ArcGISDynamicMapServiceLayer：动态服务图层，里面包含子图层

public ArcGISDynamicMapServiceLayer （String url）：全部可见
public ArcGISDynamicMapServiceLayer （String url，int [] visiblelayers）：
    int [] visiblelayers:可见图层的id,全部可见，为null

 /**
     * 动态服务图层，里面包含子图层
     * public ArcGISDynamicMapServiceLayer （String url）
     * <p>
     * public ArcGISDynamicMapServiceLayer （String url，int [] visiblelayers）
     * int [] visiblelayers:可见图层的id,全部可见，为null
     */
    private void addDynamicServiceLayer() {
        String netDynamicLayerUrl = "http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Specialty/ESRI_StateCityHighway_USA/MapServer";
        ArcGISDynamicMapServiceLayer dynamicMapServiceLayer = new ArcGISDynamicMapServiceLayer(netDynamicLayerUrl);
        // ArcGISDynamicMapServiceLayer dynamicMapServiceLayer = new ArcGISDynamicMapServiceLayer(netDynamicLayerUrl, new int[]{0});
        mMapView.addLayer(dynamicMapServiceLayer);

        dynamicMapServiceLayer.setOnStatusChangedListener(new OnStatusChangedListener() {
            @Override
            public void onStatusChanged(Object o, STATUS status) {
                if (status == STATUS.INITIALIZED) {
                    Log.e("xyh", "加载成功");
                } else if (status == STATUS.INITIALIZATION_FAILED || status == STATUS.LAYER_LOADING_FAILED) {
                    Log.i("xyh", "加载失败");
                }
            }
        });
    }

3.ArcGISFeatureLayer:加载子图层

  /**
     * 加载服务的子图层
     */
    private void addChildLayer() {
        ArcGISFeatureLayer arcGISFeatureLayer = new ArcGISFeatureLayer(netDynamicLayerUrl + "/0",
                ArcGISFeatureLayer.MODE.ONDEMAND);
        mMapView.addLayer(arcGISFeatureLayer);
        //        arcGISFeatureLayer.setRenderer(new SimpleRenderer(
        //                new SimpleLineSymbol(Color.argb(250, 52, 17, 255), 2)));
        arcGISFeatureLayer.setOnStatusChangedListener(new OnStatusChangedListener() {
            @Override
            public void onStatusChanged(Object o, STATUS status) {
                if (status == STATUS.INITIALIZED) {
                    Log.e("xyh", "加载成功");

                } else if (status == STATUS.INITIALIZATION_FAILED || status == STATUS.LAYER_LOADING_FAILED) {
                    Log.e("xyh", "加载失败");
                }
            }
        });
    }
