Does this answer your question? [Simple Android grid example using RecyclerView with GridLayoutManager (like the old GridView)](https://stackoverflow.com/questions/40587168/simple-android-grid-example-using-recyclerview-with-gridlayoutmanager-like-the) — Ricky Mo, Oct 21 '21 at 06:59
The question is ambiguous. Span count is used as part of a GridLayout to determine the number of items horizontally per row, hence the comment about GridLayoutManager. — Chris, Oct 21 '21 at 07:07
It is not `GridLayout`. It is `RecyclerView` using `GridLayoutManager`. `RecyclerView` has a `layoutManager`. There are different types of `layoutManager` to choose from. `GridLayoutManager` with a column count set to 3 suit your use case — Ricky Mo, Oct 21 '21 at 07:08
Sorry for misunderstanding. You may want to set the `height` of `itemView` to 1/3 of the parent view. You may refer to [this post](https://stackoverflow.com/questions/35221566/how-to-set-the-height-of-an-item-row-in-gridlayoutmanager) . This also applies to `LinearLayoutManager`. — Ricky Mo, Oct 21 '21 at 07:16
You have to dynamically set the height/width also after undertaking the margin . thats the only way . — ADM, Oct 21 '21 at 07:27

This will only affect the preview, not the actual running of the app – Chris Oct 21 '21 at 07:04
then use adapter to set the limit by 'getItemCount()' method return 3 it will return only 3 records on the view – Kalpesh Kulye Oct 21 '21 at 07:08
i am using same adapter for different activity. i want to set item count 3 only for one activity – Vishali Oct 21 '21 at 07:12
then while passing list to the adapter pass only 3 item – Kalpesh Kulye Oct 21 '21 at 07:17

In your adapter class, assign a return value 3 of `getItemCount(), it shows only 3 list items

override fun getItemCount(): Int {
   return 3
}

Add this condition in Your adapter getItemCount() method:

return Math.min(yourlist.size(), 3);

Like this:

@Override
    public int getItemCount() {
        return Math.min(memeberList.size(), 3);
    }
