title: Making buttons clickable at new game in Android
body: <p>I'm new at Android development and doing a simple Hangman game.</p>
  
  <p>I have a gridview which is filled by buttons for each letter(A-Z). Each button becomes unclickable after clicked and when new word has openned i want to make them clickable again. How can i do this efficiently ? I dont want to keep each clicked buttons in a list and parse it to make them clickable.</p>
