its awesome man !!!! Thanks a lot :)
ReplyDeleteHi Dhaval! Can you please demonstrate how can we get a list of all checked items? I would very much appreciate it. :)
ReplyDeleteThank you!
thnks for nic post,if i clcik getcount button i need to remove selected items and remain items i need display in lisview,what changes do i need to do in above posted code
ReplyDeleteHere you get list of selected item position:
Deletepublic void click(View v) {
if (v.getId() == R.id.button1) {
final ArrayList posSel = new ArrayList();
posSel.clear();
boolean noSelect = false;
for (int i = 0; i < thumbnailsselection.length; i++) {
if (thumbnailsselection[i] == true) {
noSelect = true;
Log.e("sel pos thu-->", "" + i);
posSel.add(i);
// break;
}
}
if (!noSelect) {
Toast.makeText(MainActivity.this, "Please Select Item!",
Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(MainActivity.this,
"Selected Items:" + posSel.toString(),
Toast.LENGTH_LONG).show();
}
}
}
using that position remove items from your arraylist and readapte your adapter with listview or you can use adapter.notifydatastatechange();
how about a .zip file , thats the least you can do if your not going to make ur code cut and paste-able
ReplyDeleteyeah man, if your going to post tutorials you gotta post a .zip to your source or at least find a snippet that will allow us to copy the code for each code chunk to a clipboard and PLEASE for gods sake take off that horriable tag that gets added to your code when we try to cut/paste from your site. it just makes ur site come off as spammy and unprofessional. if u post good, easy to implement code ppl will come back on their own .
ReplyDeletehey... now you can copy code.... from this blog...
Deletesorry for inconvenience...
