به هم ریختگی ایتم ها در اسکرول سریع ریسایکرویو

سلام

من یه سری ایتم ها رو که شامل عکس و متن هست از سرور به صورت جیسون می گیرم و در ریسایکرویو نمایش می دم مشکل اینجاس که سریع اسکرول میشه ایتم ها به هم میرزه.

مشکل از کجاس

کد بخشی که اسکرول میشه 

  public  class home_agahi3_server  extends AsyncTask<String,Void,String> {

        private Context c;
        private Activity ac;

        AgahiRecyclerAdapter adp;

        ){
