@ZakiPathan i used your solution but it makes recycler view scroll very slow. — Saikiran Bait, Mar 09 '17 at 06:58

RecyclerViewAdapter recycles its views and thus the behavior is much expected.

When I read your code I saw that you've written if statements without else like :

        if (!TextUtils.isEmpty(response.getRoomNo()))
            holder.locationEven.setText(response.getRoomNo());

        if (!TextUtils.isEmpty(response.getSubject()))
            holder.subjectEven.setText(response.getSubject());

These will be reused if the view in the position before the newly loaded view doesn't fulfill that if statement.

Try adding else to your every if statement. By adding else I mean add something like

else {
    holder.locationEven.setText("");
}

// OR

else {
    holder.locationEven.setVisibility(View.GONE);
}

Ok will try it and reply you. – Saikiran Bait Mar 09 '17 at 08:09
Yes it worked. Implement the same way as you suggested and made some changes on my own. Thank you. Saved my day :) `loadDataOdd(response, holder); if (response.isCancelled() || (response.getSubmissionStatus() != null && response.getSubmissionStatus().equals("No"))){ ChangeFontColor(holder, Enum.LayoutType.Odd); } else { ChangeFontColorBlueOdd(holder, Enum.LayoutType.Odd, response); }` – Saikiran Bait Mar 09 '17 at 08:45
Yup! I learnt it the hard way lol, glad you got it working fast! :D – Kevin Murvie Mar 09 '17 at 10:53
:D bro. Same here :X – Saikiran Bait Mar 10 '17 at 05:40

for quick fix, just add `holder.setIsRecyclable(false)` inside `onBindViewHolder`. – Gilbert Arafat Mar 20 '20 at 03:13
That's not recommended for a `RecyclerView` with many item as they're not getting recycled after setting it to false. It is, however, useful for `RecyclerView` with a small amount of known item (probably 10, I mostly do this for less amount of item like 5 ish), and relatively safe to be coded without if-else – Kevin Murvie Jun 30 '20 at 08:28
