Answer 1

If you're using material design and using custom sizes:

android:layout_width="80dp"
android:layout_height="80dp"

instead of

android:layout_width="wrap_content"
android:layout_height="wrap_content"

The fix is to use these two properties

app:fabCustomSize="80dp"
app:maxImageSize="70dp"

make sure of this

app:fabCustomSize = the same size as your layout_width
app:maxImageSize= about 10dp minus the size of your layout_width
