最近项目用到高德地图,因此来写一篇文章理一下高德的使用步骤方法,希望对大家有用!

1.注册+配置

废话不多说,要使用高德地图首先要去高德开放平台注册成为开发者(http://lbs.amap.com/), 注册成为高德开发者需要分三步:第一步,注册高德开发者;第二步,去控制台创建应用;第三步,获取Key(见下图,注意看命名规范,SHA1值得获取网上有!很简单)。


获取key


ok之后,到官网下载高德SDK(http://lbs.amap.com/api/android-sdk/download/), 我这边全部都下载了,解压后,得到一个 AMap3DMap_xxxxx(版本号).jar 文件和一个 armeabi 文件夹,之后,
(一)将jar包拷贝到你项目的libs目录下.
(二)在 main 目录下创建文件夹 jniLibs (如果有就不需要创建了),将armeabi 文件夹复制到这个目录下,如果已经有这个目录,将下载的 so 库复制到这个目录即可.
见图(也可以参考高德官网的第二种配置方式):


Studio 配置工程


别忘了添加File依赖:


FileDependencies

好了,前期准备弄好,终于可以上代码了.

2.地图

1.在清单文件中配置key:

1  <meta-data android:name="com.amap.api.v2.apikey" 
2  android:value="您申请的Key"></meta-data>

2.配置权限(把下面这堆配置进去,再也不用担心bug出在权限问题上了):

<!--允许程序打开网络套接字-->
<uses-permission android:name="android.permission.INTERNET" />
<!--允许程序设置内置sd卡的写权限-->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<!--允许程序获取网络状态-->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<!--允许程序访问WiFi网络信息-->
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<!--允许程序读写手机状态和身份-->
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<!--用于进行网络定位-->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
<!--用于访问GPS定位-->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
<!--用于获取wifi的获取权限,wifi信息会用来进行网络定位-->
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
<!--用于读取手机当前的状态-->
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
<!--用于申请调用A-GPS模块-->
<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS"></uses-permission>

3.在布局文件中加载地图控件:

<com.amap.api.maps.MapView    
android:id="@+id/map"    
android:layout_width="match_parent"    
android:layout_height="match_parent">
</com.amap.api.maps.MapView>

4.你只要在onCreate()中添加如下几行代码,高德地图就显示出来了!

MapView mapView = (MapView) findViewById(R.id.map);//找到地图控件
mapView.onCreate(savedInstanceState);// 此方法必须重写
AMap aMap = mapView.getMap();//得到一个map对象

是不是很简单!再此我还是想说下,高德地图的软实力和百度地图是有差距的,但是高德的开发文档要比百度很人性化!
接下来我们来使用定位功能在地图上添加点标记玩玩.

3.定位+添加标记

第一种方式(基础,可参考官网,链接在此:http://lbs.amap.com/api/android-location-sdk/guide/android-location/getlocation/):

//初始化定位
mLocationClient = new AMapLocationClient(getApplicationContext());
//初始化AMapLocationClientOption对象
mLocationOption = new AMapLocationClientOption();
//设置定位模式为高精度模式。
mLocationOption.setLocationMode(AMapLocationClientOption.AMapLocationMode.Hight_Accuracy);
//设置定位回调监听
mLocationClient.setLocationListener(this);
//获取一次定位结果
mLocationOption.setOnceLocation(true);
//设置是否返回地址信息(默认返回地址信息)
mLocationOption.setNeedAddress(true);
//给定位客户端对象设置定位参数
mLocationClient.setLocationOption(mLocationOption);
//启动定位
mLocationClient.startLocation();

之后在监听器的回调方法内解析AMapLocation对象,里面包含地址,省市县街道,地区编码,城市编码等等等,可以在此添加标记,定位当前位置,你问我如何把标记固定在屏幕中央?也在这里面:

//----------------------这是位置改变监听------------------------------------    
@Override    
public void onLocationChanged(AMapLocation aMapLocation) {        
      if (aMapLocation != null) {            
          if (aMapLocation.getErrorCode() == 0) {                
              //可在其中解析amapLocation获取相应内容。                         
              LatLng latLng = new LatLng(aMapLocation.getLatitude(),       
              aMapLocation.getLongitude());//取出经纬度               
             //添加Marker显示定位位置                
            if (locationMarker == null) {                    
            //如果是空的添加一个新的,icon方法就是设置定位图标,可以自定义                    
            locationMarker = aMap.addMarker(new MarkerOptions()                           
            .position(latLng).snippet("最快1分钟到达").draggable(true).setFlat(true));                    
            locationMarker.showInfoWindow();//主动显示indowindow                    
            aMap.addText(new TextOptions().position(latLng).text(aMapLocation.getAddress()));                    
            //固定标签在屏幕中央                    
            locationMarker.setPositionByPixels(mMapView.getWidth() / 2,mMapView.getHeight() / 2);                 
        } else {                   
           //已经添加过了,修改位置即可                    
          locationMarker.setPosition(latLng);                
        }                
       //然后可以移动到定位点,使用animateCamera就有动画效果                
       aMap.animateCamera(CameraUpdateFactory.newLatLngZoom(latLng, 15));//参数提示:1.经纬度 2.缩放级别                        
       }else {                          
        //定位失败时,可通过ErrCode(错误码)信息来确定失败的原因,errInfo是错误信息,详见错误码表。                
        Log.e("AmapError","location Error, ErrCode:" +aMapLocation.getErrorCode() + ", errInfo:"+ aMapLocation.getErrorInfo());            
          }       
     }    
}

第二种方式,实现OnMapLoadedListener,在回调方法中首先添加一个标记在地图中央,之后封装一个方法,开启单次定位即可:

aMap.setOnMapLoadedListener(this);
//----------------------OnMapLoaded 当地图加载完成时回调此方法------------------------------------------    
    @Override
    public void onMapLoaded() {
        MarkerOptions markerOptions = new MarkerOptions();        
        markerOptions.setFlat(true);
        markerOptions.anchor(0.5f, 0.5f);            
        markerOptions.position(new LatLng(0, 0));        
        markerOptions.snippet("最快1分钟到达").draggable(true).setFlat(true);        
        markerOptions.icon(BitmapDescriptorFactory.fromBitmap(BitmapFactory.decodeResource(getResources(),                                R.drawable.icon_loaction_start)));
        mPositionMark = aMap.addMarker(markerOptions);
        mPositionMark.showInfoWindow();//主动显示indowindow
        mPositionMark.setPositionByPixels(mMapView.getWidth() / 2,mMapView.getHeight() / 2);
        mLocationTask.startSingleLocate();    }

封装的单次定位方法在此,很简单:

//开启单次定位
public void startSingleLocate() {
    AMapLocationClientOption option=new AMapLocationClientOption();
    option.setLocationMode(AMapLocationClientOption.AMapLocationMode.Hight_Accuracy);
    option.setOnceLocation(true);
    mLocationClient.setLocationOption(option);
    mLocationClient.startLocation();
}

是时候贴张效果图图了:


是的,很丑


关于怎么让按钮悬浮在地图上?也很简单啊

<?xml version="1.0" encoding="utf-8"?>

    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <RelativeLayout 
        android:layout_width="match_parent"

                android:layout_height="wrap_content"
                android:clickable="true"
                android:src="@mipmap/hanbao"/>
            <ImageView
                android:visibility="gone"
                android:id="@+id/btn_back"
                android:layout_width="50dp"
                android:layout_height="wrap_content"
                android:src="@drawable/btn_back"/>
            <Button

                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center"
                android:gravity="center"
                android:text="打车/顺风车"/>
        </RelativeLayout>
        <ImageView

            android:layout_above="@+id/fromto_container"
            android:src="@mipmap/btn_location"/>
    </RelativeLayout>
</FrameLayout>

4.地理编码+逆地理编码

下面来说一下地理编码(地址转坐标)/逆地理编码(坐标转地址)功能,依然很简单,再次提一下高德人性化的文档!
地址转坐标实现步骤:

//构造 GeocodeSearch 对象,并设置监听。
geocodeSearch = new GeocodeSearch(this);
geocodeSearch.setOnGeocodeSearchListener(this);
//通过GeocodeQuery设置查询参数,调用getFromLocationNameAsyn(GeocodeQuery geocodeQuery) 方法发起请求。
//address表示地址,第二个参数表示查询城市,中文或者中文全拼,citycode、adcode都ok 
GeocodeQuery query = newGeocodeQuery(address, "010"); 
geocoderSearch.getFromLocationNameAsyn(query);

坐标转地址实现步骤:

geocoderSearch = new GeocodeSearch(this);
geocoderSearch.setOnGeocodeSearchListener(this);//和上面一样
// 第一个参数表示一个Latlng(经纬度),第二参数表示范围多少米,第三个参数表示是火系坐标系还是GPS原生坐标系
RegeocodeQuery query = newRegeocodeQuery(latLonPoint, 200,GeocodeSearch.AMAP); 
geocoderSearch.getFromLocationAsyn(query);

之后再回调方法中解析即可:

//------------------------坐标转地址/坐标转地址的监听回调-------------------------
//result里面有你想要的结果.
    @Override
    public void onRegeocodeSearched(RegeocodeResult result, int rCode) {
       result.getGeocodeAddressList().get(0).getLatLonPoint();
    }
    @Override
    public void onGeocodeSearched(GeocodeResult result, int rCode) {
       result.getRegeocodeAddress().getFormatAddress();
    }

5.输入提示+Poi搜索

最后是搜索提示+Poi搜索功能:
先上效果图:


Poi搜索


实现步骤:
这边已经提供了两个封装好的类,一个是输入提示 一个是Poi搜索

import android.content.Context;import android.util.Log;
import com.amap.api.services.core.AMapException;
import com.amap.api.services.help.Inputtips;
import com.amap.api.services.help.Inputtips.InputtipsListener;
import com.amap.api.services.help.Tip;
import java.util.ArrayList;import java.util.List;
/**
   * ClassName:InputTipTask <br/>
   * Function: 简单封装了Inputtips的搜索服务,将其余提示的adapter进行数据绑定
   * @author   yiyi.qi   * @version     * @since    JDK 1.6   * @see  */
public class InputTipTask implements InputtipsListener {
    private static InputTipTask mInputTipTask;
    private Inputtips mInputTips;
    private RecomandAdapter mAdapter;
    Context mContext;
    public static InputTipTask getInstance(Context context, RecomandAdapter adapter){
        if(mInputTipTask==null){
            mInputTipTask=new InputTipTask(context);
        }        //单例情况,多次进入DestinationActivity传进来的RecomandAdapter对象会不是同一个
        mInputTipTask.setRecommandAdapter(adapter);
        return mInputTipTask;
    }
    public void setRecommandAdapter(RecomandAdapter adapter){
        mAdapter=adapter;
    }
    private InputTipTask(Context context ){
        mInputTips=new Inputtips(context, this);
        }
    public void searchTips(String keyWord, String city){
        try {
            mInputTips.requestInputtips(keyWord, city);
        } catch (AMapException e) {
            e.printStackTrace();    
    }    
}
    @Override
    public void onGetInputtips(List<Tip> tips, int resultCode) {
        //v3.2.1及以上版本SDK 返回码1000是正常 千万注意
        if(resultCode==1000&&tips!=null){
            ArrayList<PositionEntity> positions=new ArrayList<PositionEntity>();
            for(Tip tip:tips){
                //经纬度 address city(adcode)
                positions.add(new PositionEntity(0, 0, tip.getName(),tip.getAdcode()));
            }
            mAdapter.setPositionEntities(positions);
            mAdapter.notifyDataSetChanged();
            PoiSearchTask poiSearchTask=new PoiSearchTask(mContext.getApplicationContext(), mAdapter);
                for(int i = 0;i<positions.size();i++){
                    PositionEntity entity = (PositionEntity)
                    mAdapter.getItem(i);
                    poiSearchTask.search(entity.address,RouteTask.getInstance(mContext.getApplicationContext()).getStartPoint().city);
                }
        }else {
            //可以根据app自身需求对查询错误情况进行相应的提示或者逻辑处理
        }
    }
}
import android.content.Context;

import java.util.ArrayList;import java.util.List;
/** 
 * ClassName:PoiSearchTask <br/>
 * Function: 简单封装了poi搜索的功能,搜索结果配合RecommendAdapter进行使用显示 <br/>
 * @author yiyi.qi * @version * @since JDK 1.6 * @see */
public class PoiSearchTask implements OnPoiSearchListener {
    private Context mContext;
    private RecomandAdapter mRecommandAdapter;
    public PoiSearchTask(Context context, RecomandAdapter recomandAdapter) {
        mContext = context;
        mRecommandAdapter = recomandAdapter;
    }
    public void search(String keyWord, String city) {
        Query query = new PoiSearch.Query(keyWord, "", city);
        query.setPageSize(10);
        query.setPageNum(0);
        PoiSearch poiSearch = new PoiSearch(mContext, query);
        poiSearch.setOnPoiSearchListener(this);
        poiSearch.searchPOIAsyn();
    }
    @Override
    public void onPoiSearched(PoiResult poiResult, int resultCode) {
        if (resultCode == 1000 && poiResult != null) {
            ArrayList<PoiItem> pois=poiResult.getPois();
            if(pois==null){
                return;
            }
            List<PositionEntity> entities=new ArrayList<PositionEntity>();
            for(PoiItem poiItem:pois){
                PositionEntity entity=new PositionEntity(poiItem.getLatLonPoint().getLatitude(),
                poiItem.getLatLonPoint().getLongitude(),
                poiItem.getTitle(),poiItem.getCityName());
                entities.add(entity);
            }
            mRecommandAdapter.setPositionEntities(entities);
            mRecommandAdapter.notifyDataSetChanged();
        }
        //TODO 可以根据app自身需求对查询错误情况进行相应的提示或者逻辑处理
    }
    @Override
    public void onPoiItemSearched(PoiItem poiItem, int i) {}}

你要做的 只是拷贝这连个类到工程中,然后在搜索的Activity中实现TextWatcher接口后,进行如下调用:

//在onTextChanged方法中调用InputTipTask 的getInstance方法
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
       if (RouteTask.getInstance(getApplicationContext()).getStartPoint() == null) {
       Toast.makeText(getApplicationContext(), "检查网络,Key等问题", Toast.LENGTH_SHORT).show();
       return;
}
InputTipTask.getInstance(getApplicationContext(), mRecomandAdapter).searchTips(s.toString(),
        RouteTask.getInstance(getApplicationContext()).getStartPoint().city);
}

输入提示完成.如果你希望点选后进行更详细的Poi搜索,也只需在相应位置调用:

//生成poiSearchTask对象
PoiSearchTask poiSearchTask=new PoiSearchTask(getApplicationContext(),mRecomandAdapter);
//开始进行POI搜索
poiSearchTask.search(mDestinaionText.getText().toString(),RouteTask.getInstance(getApplicationContext()).getStartPoint().city);

以上需要一个位置的实体Bean:

/** 
* ClassName:PositionEntity <br/>
 * Function: 封装的关于位置的实体 <br/>
 * @author yiyi.qi * @version * @since JDK 1.6
 * @see */
public class PositionEntity {
    @Override
    public String toString() {
        return "PositionEntity{" + 
               "latitue=" + latitue + 
               ", longitude=" + longitude +
                ", address='" + address + '\'' + 
               ", city='" + city + '\'' + 
               '}'; 
   }
    public double latitue;
    public double longitude;
    public String address;
    public String city;
    public PositionEntity() {}
    public PositionEntity(double latitude, double longtitude, String address, String city) {
        this.latitue = latitude;
        this.longitude = longtitude;
        this.address = address;
        this.city = city;
    }
}
