title: on hiding some buttons(by user) inside android layout, buttons should appear symmetrical in proper order as stated -
body: <p>I have a linear layout(vertical)
            inside it, I have 2 linear layouts (horizontal) both
  I have place buttons inside the linear layouts like -</p>
  
  <hr>
  
  <p>Button1 Botton2 Botton3 </p>
  
  <p>Button4 Botton5 Botton6  </p>
  
  <hr>
  
  <p>Users have the ability to hide these buttons according to their need &amp; keep the buttons they want.</p>
  
  <p>So, When Users hide the button the buttons get unaliged.
  Although I am using <strong>weight</strong> to align the button horizontally.
  Still, it looks weird and unsymmetrical when user hide some buttons
  Eg.Hiding Button1 &amp; Button3
  Result I got - </p>
  
  <hr>
  
  <pre><code>       Button2     
  </code></pre>
  
  <p>Button4 Button5 Button6</p>
  
  <hr>
  
  <p>But, I <em>want</em> it like this -</p>
  
  <hr>
  
  <p>Button2 Button4 Button5</p>
  
  <p>Button6                </p>
  
  <hr>
