Question

我的短信应用工作正常，只想发送一个位置。这意味着一旦我输入消息并输入电话号码......我点击按钮，然后该位置也作为地理编码发送（我希望收件人可以通过地图打开手机上的链接）...

任何想法如何做到这一点？ PS。我知道如何获取位置并将其放在textview中，但我不是在寻找...就像我点击按钮发送短信一样，位置是从位置管理器获取的，并与消息一起发送？

我认为您需要先设置LocationManager，然后从getLastKnownLocation获取经度和纬度，而不是等待回拨。之后您可以将位置网址添加到消息中，如下所示：

    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;

= - = - edit - = - =

您需要在清单文件中请求访问用户位置的权限，如：

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

希望这个帮助

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)
            }
}

如何获取当前位置作为地理编码并发送为Android Android？
