本文详细介绍了如何在Android应用中配置和使用Esri的ArcGIS Runtime SDK，包括Gradle配置、权限添加、地图服务加载及坐标转换等关键步骤。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

一，配置

1.在buile.gradle(Module.app)

android里面加入

packagingOptions {
    exclude 'META-INF/LGPL2.1'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/NOTICE'
}

在dependencies里加入

//添加Runtime依赖
implementation 'com.esri.arcgisruntime:arcgis-android:100.3.0'
implementation fileTree(dir: 'libs', include: ['*.jar'])

2.在buile.gradle（Project）

加入

allprojects {
    repositories {
        google()
        jcenter()

        // Add the Esri public Bintray Maven repository
        maven {
            url 'https://esri.bintray.com/arcgis'
        }
    }
}

3.在AndroidManifest.xml 添加相关权限

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
 <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true" />

完成以上步骤arcgis配置就OK了；

然后创建一个Activity

package com.example.text;
import android.graphics.Color;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import com.esri.arcgisruntime.geometry.Point;
import com.esri.arcgisruntime.geometry.SpatialReferences;
import com.esri.arcgisruntime.layers.ArcGISTiledLayer;
import com.esri.arcgisruntime.mapping.ArcGISMap;
import com.esri.arcgisruntime.mapping.Basemap;
import com.esri.arcgisruntime.mapping.Viewpoint;
import com.esri.arcgisruntime.mapping.view.Graphic;
import com.esri.arcgisruntime.mapping.view.GraphicsOverlay;
import com.esri.arcgisruntime.mapping.view.MapView;
import com.esri.arcgisruntime.symbology.SimpleMarkerSceneSymbol;
import com.esri.arcgisruntime.symbology.SimpleMarkerSymbol;
import com.example.text.Util.GPSUtil;


public class MapViewActivity extends AppCompatActivity {
    private MapView mMapView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_map_view);
       mMapView = (MapView)findViewById(R.id.mapView);

//创建并添加地图服务*********************************
        //使用中文地图
       String strMapUrl="http://map.geoq.cn/ArcGIS/rest/services/ChinaOnlineCommunity/MapServer";
        ArcGISMap map = new ArcGISMap();
        ArcGISTiledLayer arcGISTiledMapServiceLayer = new ArcGISTiledLayer(strMapUrl);
     /* 英文地图   ArcGISMap map = new ArcGISMap(Basemap.Type.TOPOGRAPHIC, 32.344914, 114.740954, 16);
        mMapView.setMap(map);*/
     //***********************************************
//创建底图、并设置底图图层
        Basemap basemap = new Basemap();
        basemap.getBaseLayers().add(arcGISTiledMapServiceLayer);
//设置地图底图
        map.setBasemap(basemap);
//设置map地图对象在MapView控件中显示
        mMapView.setMap(map);
   //gps采用的gps84坐标系，arcgis采用的是Gcj02所以要进行坐标转换
        double[] point0 = GPSUtil.gps84_To_Gcj02(32.344914,114.740954);
        Viewpoint vp = new Viewpoint(point0[0], point0[1], 2000);
        map.setInitialViewpoint(vp);
        /*double   longitude =114.740954;
        double  latitude = 32.344914;
        Point wgspoint = new Point(longitude, latitude);
        mMapView.addLayer(new ArcGISTiledMapServiceLayer(strMapUrl));
        Point mapPoint = (Point) GeometryEngine.project(wgspoint, SpatialReference.create(4326), mMapView.getSpatialReference());
        Unit mapUnit = mMapView.getSpatialReference().getUnit();
        double zoomWidth = Unit.convertUnits(3, Unit.create(LinearUnit.Code.MILE_US), mapUnit);
        Envelope zoomExtent = new Envelope(mapPoint, zoomWidth, zoomWidth);
        mMapView.setExtent(zoomExtent);*/
        Point point = new Point(point0[1], point0[0], SpatialReferences.getWgs84());
        SimpleMarkerSymbol simpleMarkerSymbol = new SimpleMarkerSymbol(SimpleMarkerSymbol.Style.CIRCLE, Color.RED, 10);
        Graphic pointGraphic = new Graphic(point, simpleMarkerSymbol);
        GraphicsOverlay graphicsOverlay = new GraphicsOverlay();
        graphicsOverlay.getGraphics().add(pointGraphic);
        mMapView.getGraphicsOverlays().add(graphicsOverlay);
    }

 
}
