Removing the shadow on an android button

问题

I have searched and tryed all found solutions to this. I need to remove the shadow from a button in android. Most of the solutions i found involve using an imagebutton and setting it's background. I tryed that and it works but my button has text so imagebutton is not an option. Unless there is a way to write to an imagebutton?

My second solution was:

android:fadingEdgeLength="0dp"

But nothing seemed to change. Third:

android:shadowColor="@color/application_transparent" />

Nothing changed here either.

I also tryed creating a custom shape with stroke 0 and setting the buttons background to it but still nothing. I prefer to do this in my Xml rather than programmatically but if that is the only way, so be it. Thanks in advance

How about

        <Button
           ..<code>

            android:stateListAnimator="@null"

           ..<code>
       </Button>

回答2:

Set Style Attribute for Button in xml

style="?android:attr/borderlessButtonStyle"

It Works.

回答3:

In my case, simply adding..

android:shadowRadius="0"

..in the xml file did the trick.

回答4:

Alternative for Attribute stateListAnimator used in API level 21 - I wrapped button inside a linear layout, both having same dimensions. Worked for my case.
