android 高德定位

今天所分享的是一个简单的高德定位，就是简单的获取当前的位置，可能高德导航要好玩点，但是目前暂未有那方面的需求，所以就只是用到了高德的一个定位。其实高德文档已经写得差不多了，但是自己做了以后就当做一个笔记吧，高德api地址是[http://lbs.amap.com/api/android-location-sdk/guide/android-location/getlocation][http_lbs.amap.com_api_android-location-sdk_guide_android-location_getlocation]

[一、build.gradle][http_lbs.amap.com_api_android-location-sdk_guide_android-location_getlocation]

//高德地图定位
        compile 'com.amap.api:location:latest.integration'

二、清单文件AndroidMainfest.xml

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>

<meta-data android:name="com.amap.api.v2.apikey" android:value="8049c3fe80541356b00a6055f0ef9789">
    </meta-data>
    <service android:name="com.amap.api.location.APSService"></service>

三、MainActivity

1、声明对象

//声明AMapLocationClient类对象
    public AMapLocationClient mLocationClient = null;
    //声明定位回调监听器
    public AMapLocationListener mLocationListener = new MyAMapLocationListener();
    //声明AMapLocationClientOption对象
    public AMapLocationClientOption mLocationOption = null;

2、高德定位方法

// 高德定位
    public void getPositioning() {
        //初始化定位
        mLocationClient = new AMapLocationClient(mContext);
        //设置定位回调监听
        mLocationClient.setLocationListener(mLocationListener);
        //初始化AMapLocationClientOption对象
        mLocationOption = new AMapLocationClientOption();
        //获取一次定位结果：
        //该方法默认为false。
        mLocationOption.setOnceLocation(true);
        //获取最近3s内精度最高的一次定位结果：
        //设置setOnceLocationLatest(boolean b)接口为true，启动定位时SDK会返回最近3s内精度最高的一次定位结果。如果设置其为true，setOnceLocation(boolean b)接口也会被设置为true，反之不会，默认为false。
        mLocationOption.setOnceLocationLatest(true);
        //设置是否返回地址信息（默认返回地址信息）
        mLocationOption.setNeedAddress(true);
        //设置是否允许模拟位置,默认为true，允许模拟位置
        mLocationOption.setMockEnable(true);
        //给定位客户端对象设置定位参数
        mLocationClient.setLocationOption(mLocationOption);
        //设置定位模式为AMapLocationMode.Hight_Accuracy，高精度模式。
        mLocationOption.setLocationMode(AMapLocationClientOption.AMapLocationMode.Hight_Accuracy);
        //启动定位
        mLocationClient.startLocation();
    }

3、高德定位回调

//    高德定位回调
    class MyAMapLocationListener implements AMapLocationListener{
        @Override
        public void onLocationChanged(final AMapLocation aMapLocation) {
            new Thread(new Runnable() {
                @Override
                public void run() {
                    Location location = new Location();
                    location.setLatitude(aMapLocation.getLatitude());
                    location.setLongitude(aMapLocation.getLongitude());
                    location.setAddress(aMapLocation.getAddress());
                    location.setCountry(aMapLocation.getCountry());
                    location.setCity(aMapLocation.getCity());
                    location.setDistrict(aMapLocation.getDistrict());
                    location.setStreet(aMapLocation.getStreet());
                    location.setStreetNum(aMapLocation.getStreetNum());
                    location.setCityCode(aMapLocation.getCityCode());
                    location.setAdCode(aMapLocation.getAdCode());
                    location.setPoiName(aMapLocation.getPoiName());
                    location.setAoiName(aMapLocation.getAoiName());
                    location.setErrorCode(aMapLocation.getErrorCode());
                    Gson gson = new Gson();
                    String json = gson.toJson(location);
                }
            }).start();
        }
    }

4、3中Location实体类

package com.iwiteks.PalmarTourism.bean;
    
    /**
     * Created by me on 2018/2/2.
     */
    
    public class Location {
        private double latitude;
        private double longitude;
        private String address;
        private String country;
        private String city;
        private String district;
        private String street;
        private String streetNum;
        private String cityCode;
        private String adCode;
        private String poiName;
        private String aoiName;
        private Integer errorCode;
    
    
        public double getLatitude() {
            return latitude;
        }
    
        public void setLatitude(double latitude) {
            this.latitude = latitude;
        }
    
        public double getLongitude() {
            return longitude;
        }
    
        public void setLongitude(double longitude) {
            this.longitude = longitude;
        }
    
        public String getAddress() {
            return address;
        }
    
        public void setAddress(String address) {
            this.address = address;
        }
    
        public String getCountry() {
            return country;
        }
    
        public void setCountry(String country) {
            this.country = country;
        }
    
        public String getCity() {
            return city;
        }
    
        public void setCity(String city) {
            this.city = city;
        }
    
        public String getDistrict() {
            return district;
        }
    
        public void setDistrict(String district) {
            this.district = district;
        }
    
        public String getStreet() {
            return street;
        }
    
        public void setStreet(String street) {
            this.street = street;
        }
    
        public String getStreetNum() {
            return streetNum;
        }
    
        public void setStreetNum(String streetNum) {
            this.streetNum = streetNum;
        }
    
        public String getCityCode() {
            return cityCode;
        }
    
        public void setCityCode(String cityCode) {
            this.cityCode = cityCode;
        }
    
        public String getAdCode() {
            return adCode;
        }
    
        public void setAdCode(String adCode) {
            this.adCode = adCode;
        }
    
        public String getPoiName() {
            return poiName;
        }
    
        public void setPoiName(String poiName) {
            this.poiName = poiName;
        }
    
        public String getAoiName() {
            return aoiName;
        }
    
        public void setAoiName(String aoiName) {
            this.aoiName = aoiName;
        }
    
        public Integer getErrorCode() {
            return errorCode;
        }
    
        public void setErrorCode(Integer errorCode) {
            this.errorCode = errorCode;
        }
    }

5、至此，3中json就是返回的定位信息json字符串信息
