Question: How to refresh a page of activity in android?
The page contains a Listview and a Gridview, I want to refresh only the Listeview.

thank you

Answer: 
Either call invalidateViews() or Call notifyDataSetChanged() on your Adapter.
You should move all the code that loads and sets the date on your ListView to a different method, and when you want to refresh only the ListView you can call your method again. 

If your ListView adapter doesn't change, then you can simply modify the data within the adapter however you want, and then call `listView.notifyDataSetChanged()` to visually update it.
