add xml layout:

<android.support.design.widget.floatingactionbutton         android:id="@+id/myfab"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:src="@drawable/your_icon"         app:elevation="4dp"         ... />

add code behind:

floatingactionbutton myfab = (floatingactionbutton) myview.findviewbyid(r.id.myfab);  myfab.setonclicklistener(new view.onclicklistener() {      public void onclick(view v) {            // todo when floating action menu third item clicked     }  });
