    <Button

Use the following code in your XML to draw a Horizontal line:

<View
                android:layout_width="match_parent"
                android:layout_height="1dp"
                android:layout_marginTop="5dp"
                android:background="#ColorValue" />

To draw a Vertical line, just alter the values of android:layout_width and android:layout_height.

Pur 1) android:layout_marginTop="10dp" and
2) android:layout_marginBottom="10dp" in xml and this should suffice your work,

the 1st point will keep distance from top and 2nd point will keep distance from bottom
