ListView refresh taking it to the top of the list

Scenario: I am using a listview with custom Adapter. I am fetching data every 5 seconds and then displaying it in the listview.

Problem: After every refresh the list scrolls at the top. I would want the list to stay as is from the scroll standpoint and just the underlying data to be refreshed.

Current code: This is called every time I fetch a new data.

mListAdapter = new CustomListAdapter(this, mListData);
mList.setAdapter(mListAdapter);

This Worked For Me:

adapter.setData(list);
adapter.notifyDataSetChanged();

You can use 

mList.setSelection(mListData.size() - CONSTANT.CONTENT_SIZE);

This way the listview will not refresh to the top. Or you can also use 

adapter.notifydatasetchanged

by updating the binded list.

Instead of your code please try to put every time you fetch data this one:

adapter.notifyDataSetChanged();

As you get new mListData then just invalidate the adapter not re-initialized the adapter you can call like this

mListAdapter.notifyDataSetChanged();

Instead of calling this, you should set the new data to the adapter and then call notifyDataSetChanged.

Hope this helps!
