        android:layout_margin="10dp"
        android:backgroundTint="@color/white"
        android:contentDescription="Chat"
        app:fabCustomSize="75dp"

Answer 2

This seems to be a bug in the Design Support Library v28.0.0.

I could workarround this by setting the scaleType programmatically.

In your case in the Java/Kotlin Code:

centerLocationButton.setScaleType(ImageView.ScaleType.CENTER)

Answer 3

After updating to SDK 28, I've got the same problem. Changing the size, scaleType, layout_gravity, etc will return the same.

My current short-term solution is using the ImageButton.

Answer 4

Instead of android:src try app:srcCompat. Is FAB only thing you are using, because if it is (judging by the pic you posted), maybe you don't need RelativeLayout as a parent, you can use android:layout_gravity="bottom|end"

Answer 5

In my situation run ok this solution app:fab_icon="@drawable/btn_back_to_top_3x" enter image description here not android:src="@drawable/btn_back_to_top_3x enter image description here

And you can add android:scaleY="1.X" android:scaleX="1.X"

for additional variation

Answer 6

My solution is app:fabCustomSize="56dp"
