Set text for a textview in a custom list view

Question

I have an issue within my custom listview. Each row of the listview contains a button and a textview when the button is clicked a certain string is assigned to the textview. First , it worked like a charm then a strange issue occurs.

When I click the button of a specific row, the required string is assigned to the next textview (That's normal) but I noticed another textview in another row also has been assigned with the string.Thus, setext(string) has been assigned to two textviews in different rows with a single click.This is the code I use in my public getView

holder.bu6.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

              holder.textViewNumber.setText(String.valueOf(counter[position]));

            }
        });

Answer 1

you can create your list with model getter setter.

public class Category {

private String category;

public String getCategory() {
    return category;
}

public void setCategory(String category) {
    this.category = category;
}

public Category(String category) {

    this.category = category;
}

}

now when you click on button then change string of that position in your list and notify your adapter.
