如何获取当前位置作为地理编码并作为 SMS Android 发送？

Question

我的 SMS 应用程序正在运行，我只想发送一个位置。意思是一旦我键入消息并输入 phone 号码...我单击按钮，该位置也作为地理编码发送（我希望收件人可以在哪里打开他们的 link phone 通过地图)...

知道怎么做吗？ Ps。我知道如何获取位置并将其放在文本视图中，但我不是在寻找那个...就像我单击按钮发送短信一样，位置是从位置管理器中获取并与消息一起发送的？

我认为你需要先设置LocationManager，然后从getLastKnownLocation获取经度和纬度，而不是等待回调。之后，您可以像这样将位置 url 添加到消息中：

    LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 2000, 10, new LocationListener() {
        @Override
        public void onStatusChanged(String s, int i, Bundle bundle) {}
        @Override
        public void onProviderEnabled(String s) {}
        @Override
        public void onProviderDisabled(String s) {}
        @Override
        public void onLocationChanged(final Location location) {}
    });
    Location myLocation = locationManager.getLastKnownLocation(LocationManager.PASSIVE_PROVIDER);
    double longitude = myLocation.getLongitude();
    double latitude = myLocation.getLatitude();
    message+="https://www.google.co.id/maps/@"+latitude+","+longitude;

并且您需要请求访问清单文件中用户位置的权限，例如：

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

试试这个（使用 Kotlin）：

getLocation(context) { location ->
        val msg = location?.let {
            "As of: ${Date(it.time)}, " +
                    "I am at: http://maps.google.com/?q=" + // Note, if you used q=@, then the link will not open in iOS
                    "${it.latitude},${it.longitude} " +
                    "my speed is: ${it.speed}"
        } ?: run {
            "Sorry, it looks GPS is off, no location found\""
        }

        sendSMS(context, address, msg, subId)
}

fun getLocation(context: Context, callback: (Location?) -> Unit) {
    fusedLocationClient = LocationServices.getFusedLocationProviderClient(context)

    fusedLocationClient.lastLocation
            .addOnSuccessListener { location : Location? ->
                val l = location?.let {location}  ?: run { null }
                callback.invoke(l)
            }
}
