  button = (Button)findViewById(R.id.button);

  button.setOnClickListener(new OnClickListener() {
 @Override public void onClick(View v) {
  isFulllScreen = !isFulllScreen;
  if (isFulllScreen) {
   button.setText(getResources().getText(R.string.exit_full_screen));
   WindowManager.LayoutParams params = getWindow().getAttributes();
   params.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN;
   getWindow().setAttributes(params);
   getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
  } else {
  button.setText(getResources().getText(R.string.full_screen));
  WindowManager.LayoutParams params = getWindow().getAttributes();
  params.flags &= (~WindowManager.LayoutParams.FLAG_FULLSCREEN);
  getWindow().setAttributes(params);
  getWindow().clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
  }
