Change the a particular textview in multiple textviews when it's respective button is clicked

Question

I have multiple items and each item has a textview specifying the number of items selected by the user. When the user clicks on a button, the respective textview must be changed displaying updated number. Is there any other way than giving each item's button and textview separate ids and writing code for them ?

Here is the xml file that helps to understand I'm new to android programming and any advice or help would be a lot of help to me. Thanks.

If they are going to always be the same layout, you should create a custom widget that extends View that contains the TextView and Button . If you never need to reference them from code you wouldn't need to write anything after doing it once. If you do need to reference it from code, you are going to have to set an id on your custom view widget in order to reference it.
