how can I set different ds:data_array lists in DSListView according to user need. I have eighteen chapters in one DSListView by list and each chapter has a different array list. I want to give the array list to that particular chapter selected by the user.

we are trying to populate the list of drop down options from a restful api or sqlite.
It show the following error.

hello, I want to know how to get the selected item when DSListView stop scrolling

the buttons can't be set in the same activity as the list picker as they aren't being alowed to be on top of it even when it's invisible

DSListView stringDSListView;
stringDSListView = findViewById(R.id.ds_sport_list);

    ArrayList<String> al = new ArrayList<>();
    al.add("umar");
    al.add("akshay");
    al.add("arun");

    ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line,al);
    stringDSListView.setAdapter(arrayAdapter);

This is the code and following is the logcat :

java.lang.IndexOutOfBoundsException: Index: 3, Size: 3

I have a Scroll View and if the ListView is open, I only can scroll the background and the list is freezing.
Are there any possibilities to fix this?
