title: Android- Button Sliding Effect
body: <p>I'd like to have a sliding effect on the arrow on the side of the screen. By the time I clicked the arrow a button will be displayed with sliding effect. I am not sure about how I can do this. </p>
  
  <p>I think I can use embedded fragment on this one but I don't know to to achieve the slide effect.</p>
