EditText values in a RecyclerView gives same value after 5th position
<p>I have a <code>RecyclerView</code> and each row has a <code>EditText</code> also. I am adding item to <code>RecyclerView</code> by searching them and then I type the quantity in the edit text. Then I send it to the server to store using json format. Item add is working perfectly. There is no edit text value swapping problem also when scrolling. I can display 5 rows in the screen.<br>
Problem is when I send item to the server, edit text values in bottom rows get the same after 5th row.
These are the rows I am adding to the recyclerview.Printed List that send to the server.</p>

<pre><code>Item : 7.50-15 10PR FM CEAT               Quantity : 1
Item : 5.60-15 04PR K 511 CEAT            Quantity : 2
Item : 2.75-18 04PR SECURA F85 CEAT (F)   Quantity : 3
Item : 3.00-17 06PR SECURA ZOOM CEAT (R)  Quantity : 4
Item : 6.50-14 10PR FM CEAT               Quantity : 5
Item : 5.00-12 04PR GRIP MASTER CEAT      Quantity : 5
Item : 4.00-08 06PR AUTO RAJA RPG         Quantity : 5
Item : 9.00-20 14PR CEAT CLT LUG          Quantity : 5
Item : 8.25-20 14PR TR PLUS SUNTRAC       Quantity : 5
Item : 7.00-15 12PR FM CEAT               Quantity : 5
