How can I draw a line to connect two or more views?
<p>I have custom views and when I place them on my Activity (or Fragment) I would like to connect them with a simple line (or if you have another idea I will listen to it).</p>

<p>So here is an example:</p>

<p><a href="https://i.stack.imgur.com/xAvq6.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/xAvq6.gif" alt="enter image description here"></a></p>

<p>As you can see, I have 2 views and when I place the second below my first one, I would like to connect the two views with a simple line. (It would be cool to draw a curved line if it's not perfectly below the other component but I am cool with just a straight line.)</p>

<p>So how can I do this? It sounds simple but I don't know how to start it.</p>
