title: java android, visibility of a button in a list view (without cliking)
body: <p>I searched a lot the internet looking for an answer but couldnt find it...so here is my question :</p>
  
  <p>I have a listView, and some rows of this listView require a button. 
  So I told myself, okay, i'm gonna put a button in every row (i'm using a simple adapter, so the shape of each row is in an extra .xml file), put them all INVISBLE, and then, when a row needs it, make the button VISIBLE.</p>
  
  <p>The problem is, how to acces the button which is in a xml file that is loaded in the simple adapter?? 
  (and WITHOUT CLICKING ON IT!! I saw a lot of answers implying cliking on it to get the view, and then do what you like, yeah okay, but what if i want to control it without cliking it?? how to get the view??)</p>
  
  <p>thanks a lot in advance and sorry if the question has already been asked!</p>
