@Override

public boolean onKeyDown(int keyCode, KeyEvent event) {

if (voiceRead.equals("open")) {

if (keyCode == KeyEvent.KEYCODE_VOLUME_UP) {

vp.setCurrentItem(vp.getCurrentItem()+1);

return true;

} else if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN) {

vp.setCurrentItem(vp.getCurrentItem()-1);

return true;

}

}

return super.onKeyDown(keyCode, event);

}
