modify the NiceSpinner.java: @Override public boolean onTouchEvent(MotionEvent event) { if (isEnabled() && event.getAction() == MotionEvent.ACTION_UP && adapter != null) { if (!popupWindow.isShowing() && adapter.getCount() > 0) { showDropDown(); } else { dismissDropDown(); } } return super.onTouchEvent(event); }
