移动GIS开发之Esri地图2D和3D切换实现

欢迎关注我的微信公众号“人小路远”哦，在这里我将会记录自己日常学习的点滴收获与大家分享，以后也可能会定期记录一下自己在外读博的所见所闻，希望大家喜欢，感谢支持！

解决 MapView和SceneView遮挡问题有两种思路，一种是利用setContentView切换layout，一种是把当前地图最小化为一个像素。本文以前者为例，第一个layout为activity_esri_map.xml，第二为activity_esri_scene.xml。

目录

一、新建地图控件

二、定义变量并加载地图

三、函数封装

四、点击运行查看效果

一、新建地图控件

在地图设计页面上新建三个Button，用于切换地图，两个2d一个3d。button1和button2为2d，button3为3d。

activity_esri_map.xml中如下：

<Button        android:layout_width="50dp"        android:layout_height="50dp"        android:layout_marginEnd="30dp"        android:onClick="button1onclick"        android:id="@+id/button1"        android:text="@string/button1"        />        <Button        android:layout_width="50dp"        android:layout_height="50dp"        android:layout_marginTop="40dp"        android:layout_marginEnd="30dp"        android:onClick="button2onclick"         android:id="@+id/button2"        android:text="@string/button2"        />     <Button        android:layout_width="50dp"        android:layout_height="50dp"        android:layout_marginTop="80dp"        android:layout_marginEnd="30dp"        android:onClick="button3onclick"         android:id="@+id/button3"        android:text="@string/button3"        />     <com.esri.arcgisruntime.mapping.view.MapView        android:id="@+id/mapView"        android:layout_width="match_parent"        android:layout_height="match_parent" >    </com.esri.arcgisruntime.mapping.view.MapView>

activity_esri_scene.xml中把上面的MapView替换为SceneView

<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>

二、定义变量并加载地图

    private MapView mMapView;    private ArcGISMap mMap;    private Portal mPortal;    private PortalItem mPortalItem_map1;    private PortalItem mPortalItem_map2;    private PortalItem mPortalItem_scene;    private SceneView mSceneView;

@Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_esri_map);        //查找并绑定名为mapView的容器        mMapView = findViewById(R.id.mapView);        //添加经纬格网        LatitudeLongitudeGrid grid = new LatitudeLongitudeGrid();        //在MapView上显示格网        mMapView.setGrid(grid);        // get the portal url for ArcGIS Online        mPortal = new Portal(getResources().getString(R.string.portal_url));          // get the pre-defined portal id and portal url        mPortalItem_map1 = new PortalItem(mPortal, getResources().getString(R.string.webmap_houses_with_mortgages_id));        // create a map from a PortalItem        mMap = new ArcGISMap(mPortalItem_map1);        // set the map to be displayed in this view        mMapView.setMap(mMap);      }

地图 链接  portal id

    <!-- arcgis online portal url -->    <string name="portal_url">http://www.arcgis.com/</string>     <!-- scenemap portal item id's --> <string name="buildings_brest">8eaff4f349d6420c99968107629246c4</string> <!-- webmap portal item id's -->    <string name="webmap_houses_with_mortgages_id">23fe7e8317ba4331b6ca72bf2a8eddb6</string>    <string name="webmap_usa_tapestry_segmentation_id">bf024b8d0b4b48f5a486070214e87c5f</string>

三、函数封装

//本处解决MaoView和SceneView遮挡问题使用的是setContentView切换layout的方法    //还有一种思路是把地图最小化为一个像素    public void button1onclick(View v){         setContentView(R.layout.activity_esri_map);        //查找并绑定名为mapView的容器        mMapView = findViewById(R.id.mapView);        //添加经纬格网        LatitudeLongitudeGrid grid = new LatitudeLongitudeGrid();        //在MapView上显示格网        mMapView.setGrid(grid);        // get the portal url for ArcGIS Online        mPortal = new Portal(getResources().getString(R.string.portal_url));        // get the pre-defined portal id and portal url        mPortalItem_map1 = new PortalItem(mPortal, getResources().getString(R.string.webmap_houses_with_mortgages_id));        // create a map from a PortalItem        mMap = new ArcGISMap(mPortalItem_map1);        // set the map to be displayed in this view        mMapView.setMap(mMap);    }     public void button2onclick(View v){         setContentView(R.layout.activity_esri_map);        //查找并绑定名为mapView的容器        mMapView = findViewById(R.id.mapView);        //添加经纬格网        LatitudeLongitudeGrid grid = new LatitudeLongitudeGrid();        //在MapView上显示格网        mMapView.setGrid(grid);        // get the portal url for ArcGIS Online        mPortal = new Portal(getResources().getString(R.string.portal_url));        // get the pre-defined portal id and portal url        mPortalItem_map2 = new PortalItem(mPortal, getResources().getString(R.string.webmap_usa_tapestry_segmentation_id));        // create a map from a PortalItem        mMap = new ArcGISMap(mPortalItem_map2);        // set the map to be displayed in this view        mMapView.setMap(mMap);    }                public void button3onclick(View v){        setContentView(R.layout.acttivity_esri_scene);        //查找并绑定名为sceneView的容器        mSceneView = findViewById(R.id.sceneView);        // get the portal url for ArcGIS Online        mPortal = new Portal(getResources().getString(R.string.portal_url));        // get the pre-defined portal id and portal url        mPortalItem_scene = new PortalItem(mPortal, getResources().getString(R.string.buildings_brest));        // create a map from a PortalItem        ArcGISScene scene = new ArcGISScene(mPortalItem_scene);        // set the map to be displayed in this view        mSceneView.setScene(scene);     }
