名前カードをリサイクル表示に更新できません

Question

名前カードを保存する際に問題があります。 PopupMenuをクリックし、名前をカードに変更するオプションを選択します。変更ダイアログを表示します。名前を編集するときはこのダイアログ名を、カードに保存をクリックします。アプリケーションが機能しなくなります。

             Toast toast = Toast.makeText(mContext, "Karta została zapisana ", Toast.LENGTH_LONG);

              tv.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL); 
             } 
             toast.show(); 
            } 
           }); 

           alert.create(); 
           alert.show(); 
           break;
