ArcGIS for Android 实现加载地图

创建第一个应用

1.前期项目准备

1.1. 创建新工程

  • 新建一个空活动项目

image

  • 选择语言、平台，修改命名等

image

1.2. 添加ArcGIS SDK

  • build.gradle (Project: <project name>)添加

    		maven {
    		    url 'https://esri.jfrog.io/artifactory/arcgis'
    		}

  • build.gradle (Module: <module name>)添加

    		implementation 'com.esri.arcgisruntime:arcgis-android:100.10.0'

  • Gradle更新：Sync Project with Gradle Files

  • AndroidManifest.xml添加

    		//网络权限
    		<uses-permission android:name="android.permission.INTERNET" />
    		//use a MapView (2D) require at least OpenGL ES 2.x:
    		<uses-feature android:glEsVersion="0x00020000" android:required="true" />

  • 在appdbuild.gradle（Module:app）的android部分指定Java版本

    		compileOptions {
    		    sourceCompatibility JavaVersion.VERSION_1_8
    		    targetCompatibility JavaVersion.VERSION_1_8
    		}

1.3. 添加MapView地图控件

  • 修改activity_main.xml，替换TextView

    		    <com.esri.arcgisruntime.mapping.view.MapView
    		            android:id="@+id/mapView"
    		            android:layout_height="fill_parent"
    		            android:layout_width="fill_parent" 
    		            tools:ignore="MissingConstraints">
    		    </com.esri.arcgisruntime.mapping.view.MapView>

2.加载在线地图

2.1.设置地图

  • 添加private MapView mMapView;

  • 引用import com.esri.arcgisruntime.mapping.view.MapView; (IDE可能会自动导入)

  • 在onCreate事件中设置地图

    		        super.onCreate(savedInstanceState);
    		        setContentView(R.layout.activity_main);
    		 
    		        mMapView=findViewById(R.id.mapView);
    		        ArcGISMap map =new ArcGISMap(Basemap.Type.TOPOGRAPHIC,34.056295,-117.195800,16);
    		        mMapView.setMap(map);

  • 重载onPause、onResume与onDestroy事件

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

2.2. 编译运行

3.加载离线地图

3.1 数据准备

在IDEA中点击菜单中的view、tool windows、device file explorer，打开如下视图，找到mnt下的sdcard，这个就是我们的手机常用的存储位置。

image

在sdcard中新建文件夹，并upload地图文件，此处上传shape file、TPK、MMPK文件

image

3.2.加载TPK地图

3.2.1.设置地图

  • 添加变量

    		    private static final String TAG =MainActivity.class.getSimpleName();
    		    private MapView mapView;
    		    private MobileMapPackage mobileMapPackage;
    		    private TileCache tileCache;
    		 
    		    private final String TPKPath=Environment.getExternalStorageDirectory()+"/EXFile/YueLuShan.tpk";

  • 添加引用

    		package com.example.ex02;
    		 
    		import android.Manifest;
    		import android.content.pm.PackageManager;
    		import android.os.Environment;
    		import android.util.Log;
    		import android.widget.Toast;
    		import androidx.annotation.NonNull;
    		import androidx.appcompat.app.AppCompatActivity;
    		import android.os.Bundle;
    		import androidx.core.app.ActivityCompat;
    		import androidx.core.content.ContextCompat;
    		import com.esri.arcgisruntime.data.TileCache;
    		import com.esri.arcgisruntime.layers.ArcGISTiledLayer;
    		import com.esri.arcgisruntime.loadable.LoadStatus;
    		import com.esri.arcgisruntime.mapping.ArcGISMap;
    		import com.esri.arcgisruntime.mapping.Basemap;
    		import com.esri.arcgisruntime.mapping.MobileMapPackage;
    		import com.esri.arcgisruntime.mapping.view.MapView;

  • 重载onCreate、onPause、onResume、onDestroy事件

    		    @Override
    		    protected void onCreate(Bundle savedInstanceState) {
    		        super.onCreate(savedInstanceState);
    		        setContentView(R.layout.activity_main);
    		 
    		        mapView=findViewById(R.id.mapView);
    		        requestPermission();
    		    }
    		  
    		     @Override
    		     protected void onPause() {
    		         mMapView.pause();
    		         super.onPause();
    		     }
    		  
    		     @Override
    		     protected void onResume() {
    		         super.onResume();
    		         mMapView.resume();
    		     }

  • 设置权限请求

    		    private void requestPermission() {
    		        String[] reqPermission=new String[]{Manifest.permission.READ_EXTERNAL_STORAGE};
    		        int reqCode=2;
    		        if (ContextCompat.checkSelfPermission(MainActivity.this,reqPermission[0])== PackageManager.PERMISSION_GRANTED){
    		            loadTPK(TPKPath);
    		        }else {
    		            ActivityCompat.requestPermissions(MainActivity.this,reqPermission,reqCode);
    		        }
    		    }
    		 
    		    @Override
    		    public void onRequestPermissionsResult(int requestCode, @NonNull @org.jetbrains.annotations.NotNull String[] permissions, @NonNull @org.jetbrains.annotations.NotNull int[] grantResults) {
    		        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    		        if (grantResults.length>0&&grantResults[0]==PackageManager.PERMISSION_GRANTED){
    		            loadTPK(TPKPath);
    		        }else {
    		            Toast.makeText(MainActivity.this,"permission denied!",Toast.LENGTH_SHORT);
    		        }
    		    }

  • 添加方法支持

    		    private boolean loadTPK(String path){
    		        try {
    		            tileCache=new TileCache(TPKPath);
    		            tileCache.loadAsync();
    		            tileCache.addDoneLoadingListener(()->{
    		                if (tileCache.getLoadStatus()== LoadStatus.LOADED){
    		                    Basemap basemap=new Basemap(new ArcGISTiledLayer(tileCache));
    		                    mapView.setMap(new ArcGISMap(basemap));
    		                }else {
    		                    String error ="Error loading mobile map package : " + tileCache.getLoadError().getMessage();
    		                    Log.e(TAG,error);
    		                    Toast.makeText(this,error,Toast.LENGTH_SHORT);
    		                }
    		            });
    		            return true;
    		        }catch (Exception e){
