如何在不使用谷歌地图和其他地图的情况下获取用户当前位置？

Posted 2021-04-09

我正在开发天气应用程序，当应用程序首次启动时，我想检测用户当前位置，但我尝试使用谷歌地图，但他们要求信用卡，以获得谷歌地图的API密钥，不幸的是，我没有信用卡。你有任何其他解决方案或替代品吗？

答案

在OnCreate中调用此函数

private void location() {
    Utils.loge(TAG, "location");
    LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
    // Define a listener that responds to location updates
    LocationListener locationListener = new LocationListener() {
        public void onLocationChanged(Location location) {
            // Called when a new location is found by the network location provider.
            Constants.location = location;
            Utils.loge(TAG, "onLocationChanged : " + location.getLatitude() + ", " + location.getLongitude());
        }

        public void onStatusChanged(String provider, int status, Bundle extras) {
        }

        public void onProviderEnabled(String provider) {
        }

        public void onProviderDisabled(String provider) {
        }
    };

    // Register the listener with the Location Manager to receive location updates
    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;
    }
    locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 1000, 0, locationListener);
}

在你的清单中：

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