android - Custom BaseAdapter or CursorAdapter or CursorLoader? -



android - Custom BaseAdapter or CursorAdapter or CursorLoader? -

i have 2 fragment:

fragment a: here user enters info , stored in database. fragment b: here entered info loaded database in listview in onresume lifecycle method.

now, problem having every time info added , fragment b opened, entire listview reloaded. want load row added listview. using custom baseapadter. no cursoradapter or cursorloader!

to avoid don't utilize setadapter() everytime info changes. i.e:

create method refresh info in adapter

class sampleadapter extends baseadapter { public void refreshdata(string[] arraydata) { this.arraydata = arraydata; notifydatasetchanged(); } }

check if adapter set in activity

if (listview.getadapter() == null) { adapter = new sampleadapter(getactivity(), data); listview.setadapter(adapter); } else adapter.refreshdata(data);
