Is there any difference between the visibility of a View.GONE view or false?

I would like to know which of these implementations is correct? 

tlb.setVisibility(View.GONE);

or 

tlb.setVisibility(false);

What's the difference between them?

According to the documentation , the setVisibility method requests a int , and not a boolean !

You can use three options:

  • View.VISIBLE

  • View.INVISIBLE (Not displayed but takes up the space in screen)

  • View.GONE (Not displayed and does not take up space on screen)

    • I believe that if you try to pass a boolean on this method, the following error should occur:

      

    Error: no suitable method found for   setVisibility (boolean) method View.setVisibility (int) is not   applicable (argument mismatch; boolean can not be converted to int)   method ImageView.setVisibility (int) is not applicable (argument   mismatch; boolean can not be converted to int) method   VisibilityAwareImageButton.setVisibility (int) is not applicable   (argument mismatch; boolean can not be converted to int)

    The property Gone causes the view to be treated as if it did not exist while Invisible is simply invisible, so it does have a difference.
