Show Snack Bar with ScrollView

I hope you can help me, I have an activity with a tab, inside this tab 2 fragment, the second with the Scroll, since the data of this are several down, in the first I show the Snack bar with a message. the problem is that the Snack Bar is shown very low since it has all the scroll. That is, in the first tab it is not shown, but if I change to the second and low there is the message. How can I show the snack bar on the first tab in the lower section?

Below the xml code:

The normal thing is that the snack is shown in the lower part of the screen but since the second tab has a scroll the snack goes to the last one and in the first tab it is not shown.

JAVA CODE WHEN CALLING THE SNACK

snackbar = Snackbar
                            .make(coordinatorLayout, getString(R.string.string_mensaje_de_sin_conexion), Snackbar.LENGTH_LONG);

                    View snackBarView = snackbar.getView();
                    snackBarView.setBackgroundColor(getResources().getColor(R.color.black));
                    TextView textView = (TextView) snackBarView.findViewById(android.support.design.R.id.snackbar_text);
                    textView.setTextColor(getResources().getColor(R.color.white));

                    snackbar.show();

I hope you can help me. Thanks
