Android Studio默认情况下如何打开标记infoWindow而不点击它？

Question

这是一种处理我的代码中的新位置的方法，我是否应该在其他地方添加标记infoWindow，以便在加载活动时显示它，或者是否存在一些简单的错误？谢谢！

private void handleNewLocation(Location location) {
    final double latitude = location.getLatitude();
    final double longitude = location.getLongitude();
    LatLng latLng = new LatLng(latitude,longitude);


    Marker marker = mMap.addMarker(new MarkerOptions().position(latLng).icon(BitmapDescriptorFactory.fromResource(R.drawable.map_marker_mini)));
    marker.showInfoWindow();
    mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
    mMap.animateCamera(CameraUpdateFactory.zoomTo(15));
    mMap.setMapType(GoogleMap.MAP_TYPE_TERRAIN);
    mMap.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter() {
        @Override
        public View getInfoWindow(Marker marker) {
            View v = getLayoutInflater().inflate(R.layout.info_window, null);

            Geocoder geocoder = new Geocoder(getApplicationContext());
            List<Address> currentLocation = null;
            try {
                currentLocation = geocoder.getFromLocation(latitude, longitude, 1);
            } catch (Exception ex) {
                ex.printStackTrace();
            }

            String address = currentLocation.get(0).getAddressLine(0);
            String city = currentLocation.get(0).getLocality();
            String postal = currentLocation.get(0).getPostalCode();
            String country = currentLocation.get(0).getCountryCode();

            TextView Address = (TextView) v.findViewById(R.id.txtAddress);
            Address.setText(address + ", " + city + ",\n " + postal + ", " + country);


            return v;
        }

        @Override
        public View getInfoContents(Marker marker) {
            return null;
        }
    });
}
