[移动开发]ArcGIS Runtime API for Android100.13.0加载TPK包、Runtime包、WMS地图服务、三维模式

ArcGIS Runtime API for Android 一直在升级，写法和用法和之前也有很大的变化。这里简单介绍一下使用ArcGIS Runtime API for Android100.13.0加载各类数据源。

加载TPK包

Tile package（TPK）：包含地图文档的缓存数据，也就是切片后的数据，TPK一方面便于用户或组织在ArcGIS Online上分享数据，另一方面也为离线条件下访问数据提供一种方案。使用ArcMap就可以生成。

       
        MapView mMapView = findViewById(R.id.mapView);
        
        ArcGISMap map = new ArcGISMap(BasemapStyle.ARCGIS_TOPOGRAPHIC);
        
        mMapView.setMap(map);
        mMapView.setViewpoint(new Viewpoint(31.734, 119.315, 10000));

        TileCache tileCache=new TileCache(Environment.getExternalStorageDirectory()+ File.separator + getString(R.string.geopackage_path));//自己的tpk包所在路径
        ArcGISTiledLayer tiledLayer = new ArcGISTiledLayer(tileCache);
        Basemap basemap = new Basemap(tiledLayer);

        ArcGISMap mMap = new ArcGISMap(basemap);

        mMapView.setMap(mMap);

加载Runtime包

Runtime包（geodatabse）:是使用ArcMap生成一个矢量要素离线包，专门提供ArcGIS 移动端开发使用，后缀名为.geodatabase。注意这个不是在目录中创建的个人地理数据库。

        //本地存储路径
        Geodatabase geodatabase=new Geodatabase(Environment.getExternalStorageDirectory()+ File.separator + getString(R.string.geopackage_path1));
        geodatabase.loadAsync();
        geodatabase.addDoneLoadingListener(()->{
            if (geodatabase.getLoadStatus() == LoadStatus.FAILED_TO_LOAD) {
                String error = "Geopackage failed to load: " + geodatabase.getLoadError();
                Log.e(TAG, error);
                Toast.makeText(this, error, Toast.LENGTH_LONG).show();
                return;
            }else {
                for (GeodatabaseFeatureTable geoPackageFeatureTable : geodatabase.getGeodatabaseFeatureTables()) {
                FeatureLayer featureLayer = new FeatureLayer(geoPackageFeatureTable);

                mMapView.getMap().getOperationalLayers().add(featureLayer);
            }
            }
            }
        );

加载WMS服务

WMS地图服务：是一种遵从OGC标准的地图服务，在开发中经常遇到，ArcGIS Server自己可以发布WMS服务，但这里我调用的是使用GeoServer发布的WMS地图服务。

        MapView mMapView = findViewById(R.id.mapView);
        ArcGISMap map = new ArcGISMap(BasemapStyle.ARCGIS_TOPOGRAPHIC);
        mMapView.setMap(map);
        mMapView.setViewpoint(new Viewpoint(-42.31384, 146.82129, 10000));

        List<String> wmsLayerNames = new ArrayList<>();
        wmsLayerNames.add("tasmania");//GeoServer中图层的名字

        // 构造服务，这里一定要注意一定要写request=GetCapabilities，不能是其他的类型
        WmsLayer wmsLayer = new WmsLayer("http://192.168.1.121:8080/geoserver/wms?service=WMS&version=1.1.0&request=GetCapabilities", wmsLayerNames);
        wmsLayer.setPreferredImageFormat(ArcGISMapImageLayer.ImageFormat.PNG);
        wmsLayer.setVisible(true);
        wmsLayer.setOpacity(0.5f);

        // 添加到地图
        map.getOperationalLayers().add(wmsLayer);

加载GeoPackage

GeoPackage在ArcGIS中支持的不是非常好，但是栅格与矢量数据都可以存储。可以使用QGIS制作gpkg的包

  GeoPackage    mGeoPackage = new GeoPackage(Environment.getExternalStorageDirectory()+ File.separator + "newGeoPackage.gpkg");

        mGeoPackage.loadAsync();
        mGeoPackage.addDoneLoadingListener(() -> {
            if (mGeoPackage.getLoadStatus() == LoadStatus.FAILED_TO_LOAD) {
                String error = "Geopackage failed to load: " + mGeoPackage.getLoadError();
                Log.e(TAG, error);
                Toast.makeText(this, error, Toast.LENGTH_LONG).show();
                return;
            }

            // 添加栅格
            for (GeoPackageRaster geoPackageRaster : mGeoPackage.getGeoPackageRasters()) {
                RasterLayer rasterLayer = new RasterLayer(geoPackageRaster);
                mMapView.getMap().getOperationalLayers().add(rasterLayer);
            }
            //添加矢量
            for (GeoPackageFeatureTable geoPackageFeatureTable : mGeoPackage.getGeoPackageFeatureTables()) {
                FeatureLayer featureLayer = new FeatureLayer(geoPackageFeatureTable);
                mMapView.getMap().getOperationalLayers().add(featureLayer);
            }
        });

三维模式

注意三维模式下：

• 很多模拟器不支持，尽量真机
• 设置OpenGL ES版本3.0

<uses-feature
        android:glEsVersion="0x00030000"
        android:required="true" />

xml

 <com.esri.arcgisruntime.mapping.view.SceneView
        android:id="@+id/sceneView"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    </com.esri.arcgisruntime.mapping.view.SceneView>

java

 SceneView sceneView=findViewById(R.id.sceneView);
        ArcGISScene scene = new ArcGISScene(BasemapStyle.ARCGIS_IMAGERY);
        sceneView.setScene(scene);
        ArcGISTiledElevationSource elevationSource = new ArcGISTiledElevationSource(
                "http://elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer");
        scene.getBaseSurface().getElevationSources().add(elevationSource);
        

        // 初始位置
        Camera camera = new Camera(28.4, 83.9, 10010.0, 10.0, 80.0, 0.0);
        sceneView.setViewpointCamera(camera);
