Gewusst wie: hinzufügen floating-action-button auf der Oberseite des scrollview

Ich eine floating-action-button, ich würde gerne auf ein scrollview, so dass die Taste leuchtet, auch wenn Sie Blättern. Ich möchte, dass es auf der Oberseite der scrollview und in der unteren rechten Ecke des Bildschirms. Welche Kombination von Ansichten muss ich HIERFÜR verwenden?

Hier ist die xml-Datei:

  • Bewegen Sie Ihre FAB nach der ScrollView in der XML. Später die Kinder in einem RelativeLayout schweben über früher Kinder auf der Z-Achse, obwohl Android 5.0 elevation Zeug spielt auch hier.
