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)
}
}
