How to draw a line between two buttons in android?

问题

I have two buttons in my xml layout as shown bellow.

I used an activity for this button click. I want to draw a line between these buttons as shown. Could someone please help me to draw the line between this by using code or XML..

You can use an custom view to draw the line such as LineView and override the onDraw.

@Override
protected void onDraw(Canvas canvas)
{
    canvas.drawLine(0, 0, getWidth(), getHeight(), m_paint);
}

Then use the XML to achieve the layout you want.

<com.android.drawable.LineView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_toRightOf="@id/leftButton"
    android:layout_toLeftOf="@id/rightButton"
    android:layout_below="@id/leftButton"
    android:layout_above="@id/rightButton"
    />
