android - What difference between static and non static viewholder in RecyclerView Adapter? -

-

what advantages of approach (using static nested class in class myadapter extends recyclerview.adapter):

static class myvh extends recyclerview.viewholder {...}

and approach (using member inner class):

  class myvh extends recyclerview.viewholder {...}

or doesn't affect performance , both approaches used?

it more java question android question. recommended use static inner classes avoid memory leaks if take instances out of class. can have @ this awesome post explains memory leaks on inner classes.

basically nyx says:

  • if declare viewholder static can reuse in other adapters. anyway, not recommend it, create new separated class , use multiple places, make more sense. 1 class 1 purpose.
  • in case of view holders, classes used inside adapter, instances should not go fragment or activity or elsewhere definition. means having static or non-static, in case of view holders, same.

answering performance question, can have @ this answer. static 1 take less memory other one, again, talking recyclers recycle instances, memory impact not problem.

i have website contains pricelist of cs:go items. now, how did this: mysql db w/ prices --> select db x ( item name ) --> echo table ( works fine ) now want translation of item names. how planned it: mysql db --> $result= ( signature character ) --> $translate = str_replace (signature character $result) however, there's issue code or str_replace think. $translate returns $result no filtering. <?php require 'lang.php'; $servername = "localhost"; $username = ""; $dbname = ""; $password = ""; // create connection $conn = new mysqli($servername, $username, $password, $dbname); // check connection if ($conn->connect_error) { die("connection failed: " . $conn->connect_error); } // filter name $sql = "select name, price utf name 'k%'"; $result = $conn->query($sql); // translate $tr = str_replace('k','karambit','$result'); // ech...
