android - performItemClick not working after setAdapter -

-

[solved]

i have following structure in code:

listview accountlistview = (listview) findviewbyid(r.id.accountlisting); arrayadapter<string> adapter = new arrayadapter<string>(this, r.layout.list_view_item, r.id.nametextview, currentaccounts); accountlistview.setadapter(adapter);  accountlistview.performitemclick(null, 0, 0);

currentaccounts array, , has data on it.

when try performitemclick after setting adapter, nullpointerexception.

i override onkeypress, run "performitemclick" , works fine.

i know why doesn't work when trying perform click after setting adapter. (after debugging saw lastvisibleposition -1) why?

[edit]

using ((listview)findviewbyid(r.id.accountlisting)).performitemclick(null, 0, 0); works, except, if used right after setting adapter. (look @ comments more info)

i trying performitemclick on oncreate() method, screen not visible user. using onwindowfocuschanged() worked! onwindowfocuschanged() on android documentation.

thanks everybody.

you passing null parameter perfomitemclick, have tried:

listview accountlistview = (listview) findviewbyid(r.id.accountlisting); arrayadapter<string> adapter = new arrayadapter<string>(this, r.layout.list_view_item,         r.id.nametextview, currentaccounts); accountlistview.setadapter(adapter); accountlistview.performitemclick(adapter, 0, 0);

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
