Set and get unique parameter in image button android

Question

I am loading list view by listview adapter class. Within that list view I have button called favorite.

ImageButton mFavorite = (ImageButton) convertView.findViewById(R.id.method_fav_btn);

There are multiple image buttons under the same id. I want to identify which button was pressed by means of setting some extra parameters to it. I am doing this for that:

mFavorite.setId(pm.getId());

And on click:

mFavorite.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        System.out.println("Id is: "+mFavorite.getId());
    }
});

But, the problem is, I have 3 items in list view. Every time I am getting same id. How to get different ids on different clicks? Thanks.

Use `v.getUd()` instead of `mFavourite` – Chris Handy Jan 14 '15 at 17:16 — Chris Handy, Jan 14 '15 at 17:16

You can use the setTag() + getTag() methods.

See here for a similar question and here for the official documentation.

I tried it. Still I am getting same value each time. – RNK Jan 14 '15 at 17:06
You are probably recreating the image button on every call. Are you using a viewholder to cahce the views? – ahodder Jan 14 '15 at 17:08

oh... actually, I got it. I was trying to do `mFavorite.getTag()` instead of `v.getTag()`; – RNK Jan 14 '15 at 17:13
