1、上一节讲了 **arcgis for android 入门与提高（一）配置环境**[https://blog.csdn.net/HB\_Programmer/article/details/119967868][https_blog.csdn.net_HB_Programmer_article_details_119967868]，接下来看看如何显示二维地图。

2、基于Android Studio，我们打开**AndroidManifest.xml**，添加**网络权限和二维控件支持**：

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

3、在**activity\_main.xml**新建MapView

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

4、导入包

import com.esri.arcgisruntime.ArcGISRuntimeEnvironment;
    import com.esri.arcgisruntime.mapping.ArcGISMap;
    import com.esri.arcgisruntime.mapping.BasemapStyle;
    import com.esri.arcgisruntime.mapping.Viewpoint;
    import com.esri.arcgisruntime.mapping.view.MapView;

5、核心代码：

ArcGISRuntimeEnvironment.setApiKey("在dashboard创建的一个很长的key");
    mMapView = findViewById(R.id.mapView);
    ArcGISMap map = new ArcGISMap(BasemapStyle.ARCGIS_TOPOGRAPHIC);
    mMapView.setMap(map);
    mMapView.setViewpoint(new Viewpoint(34.056295, -117.195800, 10000));

@Override
    protected void onPause() {
      mMapView.pause();
      super.onPause();
    }
    
    @Override
    protected void onResume() {
      super.onResume();
      mMapView.resume();
    }
    
    @Override
    protected void onDestroy() {
      mMapView.dispose();
      super.onDestroy();
    }

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.androidgistest">
    
        <uses-permission android:name="android.permission.INTERNET" />
        <uses-feature android:glEsVersion="0x00020000" 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/Theme.AndroidGISTest">
            <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"
        android:orientation="vertical"
        tools:context=".MainActivity">
    
        <com.esri.arcgisruntime.mapping.view.MapView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:id="@+id/mapview"/>
    
    </LinearLayout>

package com.example.androidgistest;
    
    import androidx.appcompat.app.AppCompatActivity;
    
    import android.os.Bundle;
    
    import com.esri.arcgisruntime.ArcGISRuntimeEnvironment;
    import com.esri.arcgisruntime.mapping.ArcGISMap;
    import com.esri.arcgisruntime.mapping.BasemapStyle;
    import com.esri.arcgisruntime.mapping.Viewpoint;
    import com.esri.arcgisruntime.mapping.view.MapView;
    
    public class MainActivity extends AppCompatActivity {
    
        MapView mMapView;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
            ArcGISRuntimeEnvironment.setApiKey("");
            mMapView = findViewById(R.id.mapview);
            mMapView.setAttributionTextVisible(false);//去logo
    
            ArcGISMap map = new ArcGISMap(BasemapStyle.ARCGIS_TOPOGRAPHIC);
            mMapView.setMap(map);
            mMapView.setViewpoint(new Viewpoint(34.056295, -117.195800, 10000));
    
        }
    
        @Override
        protected void onPause() {
            mMapView.pause();
            super.onPause();
        }
    
        @Override
        protected void onResume() {
            super.onResume();
            mMapView.resume();
        }
    
        @Override
        protected void onDestroy() {
            mMapView.dispose();
            super.onDestroy();
        }
    }
