The question is this... I have a Vertical Scrollview with 20 buttons positioned in 5x2 view, when I use the scroll I see the other 10 buttons that are hidden, but these buttons are invisible if I do not have functions defined in the select of the bank that I use to popular the buttons... Here comes the big problem, scrollView still scrolls to the last button even if it is invisible, has some way of not letting scroll beyond the buttons q are visible?

  • Where’s the master code?!

  • I don’t know how to post it formatted here =(

  • Okay, part of the code is there, at least what’s important

Instead of using: 

btnRefri[1].setVisibility(View.INVISIBLE);

Use:

btnRefri[1].setVisibility(View.GONE);

Behold that answer of Thiago Luiz Domacoski more details on the difference between VISIBLE, INVISIBLE and GONE.

And in that:

The estate Gone causes the view be treated as if existed as long as the Invisible he’s simply invisible, so yes there is difference.

  • Solved, thank you very much..... Simple and direct solution!!!! VALEEEEU

  • @Marciovieira if you want to validate the answer, feel free. = D

  • I don’t know how does it kkkkkkkk, I want to

  • @Marciovieira even found fast. ehuhe.. good luck there.
