Move Floating Action Button, which is on an Android Edittext

Try to remove the Floating Button from the CoordinatorLayout, so that it is outside the CardView:

If it does not work like this, then try to place a RelativeLayout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_height="match_parent">

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|end"
    android:layout_margin="@dimen/fab_margin"
    android:tint="@android:color/white"
    app:srcCompat="@drawable/send" />

</RelativeLayout>

What happens in your view if you put the fab between the end of the scroll and the end of LinearLayout?

</ScrollView>

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        android:layout_margin="@dimen/fab_margin"
        android:tint="@android:color/white"
        />


</LinearLayout> 

You can add the include layout then replace them with EditText and I do not see the same problem.
