Increase active area for interface widgets to allow slightly out-of-bounds touches to count

Use android:padding attribute of view class in layout.xml


				<ImageButton
			        android:id="@+id/active_area_ib_sqr_btn" 
			        android:layout_width="wrap_content"
			        android:contentDescription="@string/active_area_image"
			        android:layout_height="wrap_content"
			        android:src="@drawable/ic_square_icon"
			        android:layout_centerHorizontal="true"
			        android:layout_marginTop="10dp"
			        android:padding="30dp"
			        android:background="@drawable/image_border"/>
