How to remove FloatingActionButton's surrounding shadow?

Question

I'm trying to replace the third party FloatingActionButton with the native one which is packaged in library com.android.support:design:22.2.0.The default look has a dark shadow around the image,How can I get rid of it? I know the former one provides with the method setShadow(),but I just can't find similar one from the latter.

This is the related XML layout:

<android.support.design.widget.FloatingActionButton         android:id="@+id/alarm_front"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:src="@drawable/btn_icon_alarm_notset" /> 

And I have set its background color to yellow.

mAlarmBtn.setBackgroundTintList(ColorStateList.valueOf(getResources().getColor(R.color.floatButtonColor))); 

Answer 1

Override the default elevation of the FAB by adding:

android:elevation="0dp" 

Or in code call View.setElevation(float)

Answer 2

Add this

android:elevation="0dp" app:elevation="0dp"

It's will be like :

 <android.support.design.widget.FloatingActionButton         android:id="@+id/floatingActionButton"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:src="@drawable/ic_add"         android:elevation="0dp"         app:elevation="0dp"         app:fabSize="normal"         android:scaleType="fitCenter"/>
