How can i move a layout up on screen when another one above it is invisible in android?

I have this kind of structure in my screen and there's +/- button on my screen. On clicking - ListView inside LinearLayout_2 has been set Invisible and I want to move LinearLayout_3 up when the Listview is hidden/invisible.

<RelativeLayout Id="1">
  <LinearLayout Id="2">
       <ListView />
  </LinearLayout>
  <LinearLayout Id="3" 开发者_如何学Gobelow="LinearLayout2"/>
</RelativeLayout>

I think you want visibility to be GONE
