it's hard know sure without seeing code looks inherited or imported wrong fragment either itemlistfragment or activity using it.

your logcat shows exception as:

caused by: java.lang.classcastexception: com.example.example.masterdetail_tabs.itemlistfragment cannot cast android.support.v4.app.fragment

check usages , imports etc

import android.support.v4.app.fragment;  vs import android.app.fragment

also mindful of variants of activity , fragment can make use of types , compatible versions of api. should read , follow official android tutorial on fragments further info , proper usages.

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 $row): ?> <div id="<?=$...
