列表长度为0时，会出现adapter.getCount()为null（when the list's size equal 0, the project throw a exception that means adapter.getCount() is null）

[zhushenwudi]

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);
}

当列表是空列表时，各种bug，我在自己修改

@zhushenwudi 这个自定义数据的List列表比较繁琐。需要自定义Adapter
