Once data is changed you can call notifyDataSetChanged() to the adapter. 更改数据后，可以调用适配器的notifyDataSetChanged() 。 But, while data is been added to the list , if you are using expandableList, you will face a runtime exception saying, adapter data is changed and it's not notified. 但是，在将数据添加到列表中的同时，如果您正在使用expandableList，则将遇到运行时异常消息，说明适配器数据已更改且未通知。 So, add all the data togerther to adpater and call notifyDataSetChanged() to the adapter. 因此，将所有数据一起添加到adpater中，然后向适配器调用notifyDataSetChanged() 。
