[移动开发]arcgis for android 入门与提高（三）显示三维场景

?1、上一节讲了arcgis for android 入门与提高（二）显示二维地图https://blog.csdn.net/HB_Programmer/article/details/119985752，接下来看看如何显示三维地图。

2、基于Android Studio，我们打开AndroidManifest.xml，添加网络权限和三维控件支持：

<uses-permission android:name="android.permission.INTERNET" />
<uses-feature android:glEsVersion="0x00030000" android:required="true" />

3、在activity_main.xml新建SceneView

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

4、导入包

import com.esri.arcgisruntime.mapping.ArcGISScene;
import com.esri.arcgisruntime.mapping.ArcGISTiledElevationSource;
import com.esri.arcgisruntime.mapping.Basemap;
import com.esri.arcgisruntime.mapping.view.Camera;
import com.esri.arcgisruntime.mapping.view.SceneView;

5、核心代码：?

ArcGISScene scene = new ArcGISScene();
scene.setBasemap(Basemap.createImagery());
//scene.setBasemap(Basemap.createTopographic());

mSceneView = findViewById(R.id.sceneView);
mSceneView.setScene(scene);

ArcGISTiledElevationSource elevationSource = new ArcGISTiledElevationSource("https://elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer");
scene.getBaseSurface().getElevationSources().add(elevationSource);

Camera camera = new Camera(33.2, 112.1, 300000, 0.0, 10.0, 0.0);
mSceneView.setViewpointCamera(camera);

@Override
protected void onPause() {
  super.onPause();
  // pause SceneView
  mSceneView.pause();
}

@Override
protected void onResume() {
  super.onResume();
  // resume SceneView
  mSceneView.resume();
}

@Override protected void onDestroy() {
  super.onDestroy();
  // dispose SceneView
  mSceneView.dispose();
}

6、完整代码：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.android3dscene">

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-feature android:glEsVersion="0x00030000" android:required="true" />
    
    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

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

</LinearLayout>

package com.example.android3dscene;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;

import com.esri.arcgisruntime.mapping.ArcGISScene;
import com.esri.arcgisruntime.mapping.ArcGISTiledElevationSource;
import com.esri.arcgisruntime.mapping.Basemap;
import com.esri.arcgisruntime.mapping.view.Camera;
import com.esri.arcgisruntime.mapping.view.SceneView;

public class MainActivity extends AppCompatActivity {

    private SceneView mSceneView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ArcGISScene scene = new ArcGISScene();
        scene.setBasemap(Basemap.createImagery());
        //scene.setBasemap(Basemap.createTopographic());

        mSceneView = findViewById(R.id.sceneView);
        mSceneView.setScene(scene);

        ArcGISTiledElevationSource elevationSource = new ArcGISTiledElevationSource("https://elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer");
        scene.getBaseSurface().getElevationSources().add(elevationSource);

        Camera camera = new Camera(33.2, 112.1, 300000, 0.0, 10.0, 0.0);
        mSceneView.setViewpointCamera(camera);
    }

    @Override
    protected void onPause() {
        super.onPause();
        mSceneView.pause();
    }

    @Override
    protected void onResume() {
        super.onResume();
        mSceneView.resume();
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        mSceneView.dispose();
    }

}
