问题 I have a RecyclerView list that shows a vertical list of CardViews. The AppBar has an action_search MenuItem that handles a SearchView method when clicked on. The SearchView runs a filter method that allows the CardView data to be searched. I set up a filterList to hold filtered CardViews from the search results.

问题 I'm trying to programmatically click on an item of a recyclerView. I'm using: recyclerView.findViewHolderForAdapterPosition(index).itemView.performClick(); This perfectly works when the index is of a visible item.

When the user enters text in the edittext and hits the Button, the app makes an Api call, my just added text is added to an existing list,and fetches the list of items. Now, my issue is that that the api call is successful and I get the list with my new item properly. But when I show it in the listview, the first item in the ListView is never visible.
