    android:drawableTop="@drawable/home_icon"
    android:text="Settings"
    />

Answer 1

Set

android:scaleType="fitXY"

Also wrap_content is the preferred Parameter for width and height so that the OS will automatically adjust depending upon the screen size. Please refer to Android - Image Button Scale and Adjusting the size of an ImageButton in Android
