title: Make My View Center Bottom in its Parent View?
body: <p>How could I make my view (like an <code>ImageView</code> other <code>View</code>) center bottom in its parent view ? As in this picture below.</p>
  
  <p>The parent layout could use any layout, <code>LinearLayout</code>, <code>FrameLayout</code>.</p>
  
  <p>I Know that <code>MapView</code> has the center and bottom property, but I don't find the property in <code>LinearLayout</code> or <code>FrameLayout</code>. </p>
  
  <p>Thanks very much . </p>
  
  <p>My English is not good, please forgive me my grammar error..</p>
