title: android- meaning of layout_weight="0"
body: <p>I am using <code>layout_weight</code> to specify the ratios of various views in a specific <code>viewGroups</code> in android.<br>
   From <a href="https://stackoverflow.com/questions/3995825/what-does-androidlayout-weight-mean">this</a> question's answer I have got clear concept about what <code>layout_weight</code> is. I calculate the size of all <code>views</code>in a <code>viewGroup</code> using normal mathematics (i.e I have 3 <code>views</code> of 1,2 &amp; 3 <code>layout_weights</code> &amp; all of them have <code>layout_height</code>="0dp" then they have 1/(1+2+3), 2/(1+2+3), 3/(1+2+3) spaces in their <code>viewGroup</code> for Verical alignment).<br>
  But, what does <code>layout_weight</code>="0" mean? How can I determine the view's size having <code>layout_weight</code>="0"?</p>
