make sure you add namespace in view file too.
//in view_file_name.php
use yii\helpers\ArrayHelper;

You Did not show the code . So i am not able to give you the exact answer: But you ask that you want to use array helper in your view so try this: it is working .
use app\models\User;
use yii\helpers\ArrayHelper;
//use app\models\user;
$user=User::find()->all();
//use yii\helpers\ArrayHelper;
$listData=ArrayHelper::map($user,'user_id','username');
echo '<pre>';
print_r($listData);
echo '</pre>';
