Android listview repeating some elements in a clickitem click element

This is my screenshot

This is 1 list item (contains 1 image and 3 image buttons and an identifier). My ListView has 50 ListItem.

in this case, when the user clicks on the button (first button), updates the value and sets the text to this specific position (this works). But it repeats a value similar to this (when you click on the first one, like the button-> Position 0, then it repeats the value for the 4th, 7th, etc. Position.

How to solve the problem of repeating the given text for each 4th element?

Please help me. Thanks at Advance.
