    @Override
    public void setData(Object object) {
        Logger.d("被调了");
        super.setData(object);
        if (object != null) {
            ArrayList<HashMap<String, Object>> arrayList = null;
            if ((new ArrayList<HashMap<String, Object>>()).getClass().isInstance(object)) {
                arrayList = (new ArrayList<HashMap<String, Object>>()).getClass().cast(object);
            }
            classifyselect.setViews(arrayList);
        }
    }
