I have added a floating action button in my layout but using backgroundtilt, it doesn't change the color of background.
Here my code segment
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/AddNewButton"
android:background="@drawable/add"
android:layout_margin="15dp"
app:rippleColor="@android:color/white"
app:fabSize="normal"
android:clickable="true"
app:layout_anchor="@+id/HeaderSection"
app:layout_anchorGravity="bottom|right|end"/>
