How can I remove the white spaces around these ImageButtons?

ImageButtons

This is sample code for one one of the ImageButton:

<ImageButton
        android:id="@+id/imageButton3"
        android:layout_width="64dp"
        android:layout_height="56dp"
        android:src="@drawable/ic_circulo"
        app:layout_constraintBottom_toTopOf="@+id/imageButton2"
        app:layout_constraintStart_toStartOf="parent" />

Thanks in advance.
