I have implemented floating action with list item and setting elevation from layout and run time on bind data as well. Then following issues occur:

  1. fab elevation showing on first item only that is from xml resource I think.
  2. setElevation() not working run time.
  3. fab show()/hide() also not working with scale animation.

xml code is here:

        <android.support.design.widget.FloatingActionButton
            android:id="@+id/fab_btn_video"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentEnd="true"
            android:layout_alignParentRight="true"
            android:layout_alignTop="@+id/parentLayout"
            android:layout_marginEnd="@dimen/fab_margin"
            android:layout_marginRight="@dimen/fab_margin"
            android:src="@drawable/ic_av_videocam"
            app:elevation="@dimen/fab_shadow"
            tools:targetApi="lollipop" />

This worked for me to change elevation:

fab.setCompatElevation(8f); //API>=21

You can try to use com.google.android.material.floatingactionbutton.FloatingActionButton instead of android.support.design.widget.FloatingActionButton. This will allow you to use show() and hide() methods.
