Android利用高德地图实现定位功能

根据高德官方获得key和配置Android Studio
https://lbs.amap.com/api/android-location-sdk/guide/create-project/get-key

目前我只用了定位
依赖：

    implementation fileTree(include: ['*.jar'], dir: 'libs')
    allprojects { repositories { jcenter() } }

    implementation 'com.amap.api:map2d:latest.integration'
    implementation 'com.amap.api:navi-3dmap:latest.integration'
    implementation 'com.amap.api:search:latest.integration'
    implementation 'com.amap.api:location:latest.integration'

在build.gradle中加入

android{
ndk { //设置支持的SO库架构（开发者可以根据需要，选择一个或多个平台的so）
            abiFilters "armeabi", "armeabi-v7a", "arm64-v8a", "x86", "arm64-v8a", "x86_64"
        }
}

直接调用getLocation();

    public AMapLocationClient mLocationClient = null;
    //声明定位回调监听器
    public AMapLocationListener mLocationListener = new AMapLocationListener() {
        @Override
        public void onLocationChanged(AMapLocation aMapLocation) {
            Log.d("Location", "mLocationListener>>>>: ");
            if (aMapLocation != null) {
                if (aMapLocation.getErrorCode() == 0) {
                    //可在其中解析amapLocation获取相应内容。
                    aMapLocation.getAddress();
                    Log.d("Location", "aMapLocation.getAddress(): " + aMapLocation.getAddress()+"坐标"+aMapLocation.getLatitude());
                    //tv_location.setText(aMapLocation.getAddress());
                    et_signUPaddress.setText(aMapLocation.getAddress());
                } 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());
                }
            }
        }
    };
    //声明AMapLocationClientOption对象
    public AMapLocationClientOption mLocationOption = null;

    public void getLocation() {
        //初始化定位
        mLocationClient = new AMapLocationClient(getApplicationContext());
        //设置定位回调监听
        mLocationClient.setLocationListener(mLocationListener);
        //初始化AMapLocationClientOption对象
        mLocationOption = new AMapLocationClientOption();
        /**
         * 设置定位场景，目前支持三种场景（签到、出行、运动，默认无场景）
         */
        //不允许模拟定位
        mLocationOption.setMockEnable(false);
        mLocationOption.setLocationPurpose(AMapLocationClientOption.AMapLocationPurpose.SignIn);
        if (null != mLocationClient) {
            mLocationClient.setLocationOption(mLocationOption);
            //设置场景模式后最好调用一次stop，再调用start以保证场景模式生效
            mLocationClient.stopLocation();
            mLocationClient.startLocation();
        }
        //设置定位模式为AMapLocationMode.Hight_Accuracy，高精度模式。
        mLocationOption.setLocationMode(AMapLocationClientOption.AMapLocationMode.Hight_Accuracy);
        //给定位客户端对象设置定位参数
        mLocationClient.setLocationOption(mLocationOption);
        //启动定位
        mLocationClient.startLocation();
//        mLocationClient.stopLocation();//停止定位后，本地定位服务并不会被销毁
//        mLocationClient.onDestroy();
    }
