You can get list position by name using below function.

@Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (!(o instanceof YourModel)) return false;
        YourModel that = (YourModel) o;
        return Objects.equals(itemName, that.itemName);
    }

After that you can scroll to particular position using scrollToPosition(position);

is it possible that i can set some value of list's items and scroll the list to that value like i have three button and want to scroll list to specific value set by on each button click – Rahul Korjani Oct 05 '19 at 08:02
This is method is for get list position by value. Suppose, you have list with id, name. [ { "id": 1, "name": "abc" }, { "id": 2, "name": "XYZ" } ] Now, you can get "XYZ" position using this function. @Override public boolean equals(Object o) { if (this == o) return true; if (!(o instanceof YourModel)) return false; YourModel that = (YourModel) o; return Objects.equals(name, that.name); } yourList.get("XYZ") => get list position of "XYZ" value. – Amit Viradiya Oct 05 '19 at 10:20

For scroll to any postition X:

getListView().setSelection(X);

Smoothly scroll to the specified adapter position.

smoothScrollToPosition(int position)

if you are using Recyclerview then try this

yourRecyclerview.scrollToPosition(position);

And if you are using ListView then try this

// For smooth scroll:
getListView().smoothScrollToPosition(position);

//For direct scroll
getListView().setSelection(position);
