一个高德定位Utils

进入高德平台创建应用获取key,下载sdk。这边我只需要定位

AMap_Location_V4.2.0_20180809.jar

放入libs

在Manifest里面配置

  <!--高德地图定位-->
        <meta-data android:name="com.amap.api.v2.apikey" android:value="913e56****************6639f38">
        </meta-data>
        <service android:name="com.amap.api.location.APSService"></service>

基本配置完毕。

接下来创建LocationUtils

注释也很清楚

public class LocationUtils {
    private static AMapLocationClient mlocationClient;
    //声明mLocationOption对象
    public static AMapLocationClientOption mLocationOption = null;

    public static AMapLocation sLocation = null;

    public static void init(Context context) {
        mlocationClient = new AMapLocationClient(context);
        //初始化定位参数
        mLocationOption = new AMapLocationClientOption();
        //设置定位模式为高精度模式,Battery_Saving为低功耗模式,Device_Sensors是仅设备模式
        mLocationOption.setLocationMode(AMapLocationClientOption.AMapLocationMode.Hight_Accuracy);
        //设置定位间隔,单位毫秒,默认为2000ms
        mLocationOption.setInterval(2000);
        //设置定位参数
        mlocationClient.setLocationOption(mLocationOption);
    }

    public interface MyLocationListener {
         void result(AMapLocation location);
    }

    // 获取之前定位位置,如果之前未曾定位,则重新定位
    public static void getLocation(MyLocationListener listener) {
        if (sLocation == null) {
            getCurrentLocation(listener);
        } else {
            listener.result(sLocation);
        }
    }

    // 获取当前位置,无论是否定位过,重新进行定位
    public static void getCurrentLocation(final MyLocationListener listener) {
        if (mlocationClient == null) {
            return;
        }
        // 设置定位监听
        mlocationClient.setLocationListener(new AMapLocationListener() {
            @Override
            public void onLocationChanged(AMapLocation location) {
                if (location != null) {
                    //定位成功,取消定位
                    mlocationClient.stopLocation();
                    sLocation = location;
                    listener.result(location);
                } else {
                    //获取定位数据失败
                }
            }
        });
// 启动定位
        mlocationClient.startLocation();
    }

    public static void destroy() {
        mlocationClient.onDestroy();
    }
}

如何调用?

先全局初始化,创建一个MyApplication类进行初始化。

public class MyApp extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        LocationUtils.init(this);
    }
}

在需要调用的地方直接调用

如:

    LocationUtils.getLocation(new LocationUtils.MyLocationListener() {
            @Override
            public void result(AMapLocation location) {
                if (location.getErrorCode() == 0) {
                    //针对location进行相关操作,如location.getCity(),无需验证location是否为null;
                    String city = location.getCity();
                    String country = location.getCountry();
                    String cityCode = location.getCityCode();
                
                } else {
                    Log.e("AmapError", "location Error, ErrCode:"
                            + location.getErrorCode() + ", errInfo:"
                            + location.getErrorInfo());
                }
            }
        });

这样一个定位的utils完成。~~
