  WindowManager.LayoutParams params = getWindow().getAttributes();
  params.alpha = .85f;    // lower than one makes it more transparent
  params.dimAmount = .6f;  // set it higher if you want to dim behind the window
  getWindow().setAttributes(params);
  getListView().setAlpha(.85f);
  // Gets the display size so that you can set the window to a percent of that
  Display display = getWindowManager().getDefaultDisplay();

  // You could also easily used an integer value from the shared preferences to set the percent

  } else {
