title: Android: Up/down animated sliding menu
body: <p>I have tried several solutions but need help. The topics below are really useful but I think I'm doing something wrong. How to set layout height/settings for both? Let's say I have 2 LinearLayout for content and bottom menu.</p>
  
  <p>Also I don't want the bottom menu disappeared after sliding. It should be constant there. I am using fragments for menu clicks/change views.</p>
