android - How to add a Contextual Action Bar to a Dialog -

-

i have several cases gridview within dialogfragment needs contextual menu. project supports api 8+, i'm using appcompat support library. far i've tried calling activity.startsupportactionmode() on underlying actionbaractivity, starts contextual actionbar/actionmode underneath dialog. i'm looking alternative common-but-hacky (and high-overhead) method of using activity themed dialog.

poking around in source both framework , appcompat support library, get:

for api 11+ standard framework:

dialog dialog; actionmode.callback actionmode;  window window = dialog.getwindow(); view toplevel = window.getdecorview(); if (toplevel == null) { return; }  toplevel.startactionmode (actionmode);

for appcompat support library:

window window = dialog.getwindow(); view toplevel = window.getdecorview(); if (toplevel == null) { return; }  android.view.actionmode.callback frameworkactionmode =      new callbackwrapper (context, supportactionmode); toplevel.startactionmode (frameworkactionmode);

note if you're using dialogfragment, you'll need reference getdialog(), which may null, depending on in dialogfragment lifecycle.

as of revision 19.1.0 (mar 2014), appcompat support library includes internal class (android.support.v7.internal.view.actionmodewrapper.callbackwrapper) can used wrap support-library actionmode.callback in framework callback. if prefer not rely on internal classes, can roll own wrapper.

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
