Snackbar and FloatingActionButton bug

Question

I have a FAB button in a Coordinator Layout, and I have set snackbars to pop up in the Coordinator Layout. However if a snackbar is visible and I execute an action that triggers another snackbar while the first one is still visible, the FAB button glitches and falls behind the snackbar. Instead of moving with the snackbar.

I have the Coordinator Layout within a Relative Layout though with an adview below the Coordinator Layout.

This is the layout.xml

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

How about moving the FAB up with the snackBar. I guess that will fix your problem. Whenever a snackBar is shown do this ,

SnackbarManager.show(
Snackbar.with(getApplicationContext()) // context
    .text("This will do something when dismissed") // text to display
    .eventListener(new EventListener() {
        @Override
        public void onShow(Snackbar snackbar) {
            myFloatingActionButton.moveUp(snackbar.getHeight());
        }
        @Override
        public void onShown(Snackbar snackbar) {
            Log.i(TAG, String.format("Snackbar shown. Width: %d Height: %d Offset: %d",
                    snackbar.getWidth(), snackbar.getHeight(),
                    snackbar.getOffset()));
        }
        @Override
        public void onDismiss(Snackbar snackbar) {
            myFloatingActionButton.moveDown(snackbar.getHeight());
        }
        @Override
        public void onDismissed(Snackbar snackbar) {
            Log.i(TAG, String.format("Snackbar dismissed. Width: %d Height: %d Offset: %d",
                                snackbar.getWidth(), snackbar.getHeight(),
                                snackbar.getOffset()));
        }
    }) // Snackbar's EventListener
, this); // activity where it is displayed

Let me know if it works for you...
