android - How update a view without refresh all view? -
example: using listview, 10 items database , show on view. when user scroll down , click in button, wanna bring database , show 10 more items. don't wanna refresh whole view, add 10 more.
i using cursor , adapter listview, so, when swap cursor new data, adapter fill listview refreshing items.
i'm looking tutorial, class or idea make that.
listview
old class added way @ start in api level 1. adapters use listview
have notifydatasetchanged()
refreshing data displayed.
google aware of limitation , on year ago released recyclerview
, more advanced , flexible replacement listview
.
recyclerview.adapter
class has many more methods such as;
notifyitemrangeinserted(int positionstart, int itemcount)
ideal method situation here.
using support library recyclerview
give compatibility right api 7 (android 2.1 eclair).
