[android-developers] Re: Again Back button issue
Ohh!! I just coy and paste that previous code, and by mistake I forgot
to remove that line. But now after removing
startActivity(getIntent()); item is deleted but list is not updated
instantly.
I read somewhere I must have to use notifyDataSetChanged(); How to
use this?
