android利用本地定位来获取经纬度

首先在onCreate() or onResume()中定义一个方法 getLocation(this)，下面的代码是具体内容：

  /**
     * 调用本地GPS来获取经纬度
     * @param context
     */
    private void getLocation(Context context) {
        //1.获取位置管理器
        locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
        //2.获取位置提供器，GPS或是NetWork
        List providers = locationManager.getProviders(true);
        if (providers.contains(LocationManager.NETWORK_PROVIDER)) {
            //如果是网络定位
            locationProvider = LocationManager.NETWORK_PROVIDER;
        } else if (providers.contains(LocationManager.GPS_PROVIDER)) {
            //如果是GPS定位
            locationProvider = LocationManager.GPS_PROVIDER;
        } else if (providers.contains(LocationManager.PASSIVE_PROVIDER)) {
            //如果是PASSIVE定位
            locationProvider = LocationManager.PASSIVE_PROVIDER;
        }
        else {
            Toast.makeText(this, "没有可用的位置提供器", Toast.LENGTH_SHORT).show();
            return;
        }

        //3.获取上次的位置，一般第一次运行，此值为null
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        }
        Location location = locationManager.getLastKnownLocation(locationProvider);
        if (location != null) {
            showLocation(location);
        } else {
            // 监视地理位置变化，第二个和第三个参数分别为更新的最短时间minTime和最短距离minDistace
            locationManager.requestLocationUpdates(locationProvider, MIN_TIME, MIN_DISTANCE, mListener);
        }
    }


 LocationListener mListener = new LocationListener() {
        @Override
        public void onStatusChanged(String provider, int status, Bundle extras) {
        }

        @Override
        public void onProviderEnabled(String provider) {
        }

        @Override
        public void onProviderDisabled(String provider) {
        }

        // 如果位置发生变化，重新显示
        @Override
        public void onLocationChanged(Location location) {
            showLocation(location);
        }
    };

 /**
     * 获取经纬度
     * @param location
     */
    private void showLocation(Location location) {
        longtitude=String.valueOf(location.getLongitude());
        latitude=String.valueOf(location.getLatitude());
        Log.e("经纬度信息：",longtitude+"  "+latitude);
    }
