Hi @adolfdsilva,

Could you share with us your xml layout and java code ?

[adolfdsilva]

Ya I think I got the error. If you remove the text attribute fancy:fb_text="test" It crashes, does the button need a default fb_text value? Below is my code

<mehdi.sakout.fancybuttons.FancyButton android:id="@+id/bConfirmed" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/tvOrderNo" android:layout_centerHorizontal="true" android:layout_marginTop="8dp" android:paddingBottom="8dp" android:paddingLeft="44dp" android:paddingRight="44dp" android:paddingTop="8dp" fancy:fb_borderColor="@color/md_yellow_700" fancy:fb_borderWidth="1dp" fancy:fb_defaultColor="@android:color/transparent" fancy:fb_focusColor="@color/md_grey_300" fancy:fb_radius="6dp" fancy:fb_text="@string/button_confirmed" fancy:fb_textColor="@color/md_yellow_700" />

According to your code, I don't see any filling value (text or icon). Make sure you add one or if you want an empty button, just set fancy:fb_text=""

Ok,so one of this is necessary while inflating, you can't directly set it at run time.

Thanks for the help!!!!

As a heads up, I followed these steps and faced the same problem. If I had it within a Relative Layout, it would break and throw this exception. If I had it outside of the layout, it would work just fine. I finally had to set everything statically within the xml and then change the text dynamically to get it to work.
