title: How to block any click on the screen until dialog show animation complete?
body: <p>I'm writing puzzle game. When CountDownTimer finishes, dialog is displayed. Dialog displayed with animation. If I click anywhere on the screen until dialog showing animation is completed, then game returns to the first level. Today I noticed another unexpected behavior. I finished level at the same time with timer finish and as result I had two dialogs: TimeOverDialog and LevelCompleteDialog. So, what I have to do to solve this problem? 
  Sorry for my English!</p>
