Retrieving an element from array list in Android?

Question

I am trying to implement voice recognition code in Android. How do I get an element at a particular position from array list in Android? I tried converting arraylist

Answer 1

I have a list of positions of array to retrieve ,This worked for me.

  public void create_list_to_add_group(ArrayList arrayList_loc) {
     //In my case arraylist_loc is the list of positions to retrive from 
    // contact_names 
    //arraylist and phone_number arraylist

    ArrayList group_members_list = new ArrayList<>();
    ArrayList group_members_phone_list = new ArrayList<>();

    int size = arrayList_loc.size();

    for (int i = 0; i < size; i++) {

        try {

            int loc = arrayList_loc.get(i);
            group_members_list.add(contact_names_list.get(loc));
            group_members_phone_list.add(phone_num_list.get(loc));


        } catch (Exception e) {
            e.printStackTrace();
        }


    }

    Log.e("Group memnbers list", " " + group_members_list);
    Log.e("Group memnbers num list", " " + group_members_phone_list);

}
