I cannot find a way to get a FAB with no border. For example when I try:
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/fab"
android:background="@android:color/transparent"
android.support.design:fabSize="normal"
android:adjustViewBounds="true"
style="@style/Fab"/>
I get:
Notice the border still around the FAB. I have tried adjustViewBounds=”true” and android:background=”@android:color/transparent” both of which are the suggested solutions for getting rid of the border on an ImageView (which FAB extends) but neither work. How can I get rid of this border?
Note: all @style/Fab does is position the button, nothing to do with border.
Just add app:borderWidth="0dp" in your layout file:
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/fab"
app:borderWidth="0dp"
android:background="@android:color/transparent"
android.support.design:fabSize="normal"
android:adjustViewBounds="true"
style="@style/Fab"/>
There is also added advantage of adding this, it fixes the problem of square FAB in API<15.
Update: The latest update for android support does not need borderwidth=0dp to fix the square FAB.

Answer to comment by @Zvi
To make background of the button transparent, use this line :
app:backgroundTint="#00FFFFFF"
The hash code for transparent background is : #00FFFFFF
To change the color of the icon inside the button, use this :
android:tint="#800080"
#800080 is the hash code for purple
For accessing hash codes for different colors, go here: http://www.color-hex.com/color-palettes/
Just copy the hash codes and paste it wherever you want it.

Turns out it was
app:borderWidth="0dp"
How stupid of me. Thank you @Ranjith.
This somehow also added a shadow under the button:
