android - Refill Layout when hiding some elments

Question

I would like to show different elements to the user.
Therefore I would like to hide some elements, while others will show.
However, replaced elements cannot fill up the original area.

So are there any method to replace it.?

Answer 1

Yes, you can do that, using

setVisibility(View.GONE) 

(instead of View.INVISIBLE).
