It worked well in my case. First, you download an image and rename it as iconimage, locates it in the drawable folder. You can change the size by setting android:layout_width or android:layout_height. Finally, we have

 <ImageButton
        android:id="@+id/answercall"
        android:layout_width="120dp"
        android:layout_height="80dp"
        android:src="@drawable/iconimage"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:scaleType="fitCenter" />
