Cant convert String to double-CodePudding

So I got the latitude and longitude and successfully saved it on firebase, and now I was able to retrieve it and paste their values on a TextView.

I am planning to get the string value from the TextView and convert it to double and use that as a latitude and longitude to show a location on a map. I followed the format for converting string value to double value and it still wont work.

This is my code:

@Override public void onMapReady(GoogleMap googleMap) { mMap = googleMap;

    String latitude = textViewLatt.getText().toString();
    String longitude = textViewLong.getText().toString();

    //Double latitude = Double.valueOf(textViewLatt.getText().toString());
    //Double longitude = Double.valueOf(textViewLong.getText().toString());

    double latt = Double.parseDouble(latitude);
    double longi= Double.parseDouble(longitude);

    //double latt = Double.valueOf(latitude);
    //double longi = Double.valueOf(longitude);

    // Add a marker in Sydney and move the camera
    LatLng sydney = new LatLng(latt, longi);
    mMap.addMarker(new MarkerOptions()
            .position(sydney)
            .title("Marker"));
    mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));

and these are the errors I got from debugging, I tried to search the problem and I couldnt find any solutions. Any help will be great.

Check your text views, you are somehow failed to set the Digits of Lat Long values in TextViews properly and they contains alphabets thats why you are unable to parse them into Double.

Update: I found the problem, it seems like its getting the value even before I change the textview's value into numbers. thus it was trying to convert "latitude"(the previous value of the textview) to a double and instead of the coordinates.

Thank you for your suggestions guys!
