What ways can be used to add new features to a standard list in your program?

To add new features to the standard list in Android (for example, to ListView or RecyclerView), you can use several approaches:

1. Inheritance and extension of the adapter — create your own adapter class that extends the standard one (such as ArrayAdapter or RecyclerView.Adapter), and add the necessary logic.

2. Using decorators or wrappers — wrap the standard list or adapter in a class that adds functionality (for example, adding headers, dividers).

3. Composition with custom elements — create your own layouts for list items with additional features and use them in the adapter.

4. Using libraries and extensions — apply third-party libraries that extend the functionality of standard lists.

Example of extending an adapter to add click functionality to items:

public class MyAdapter extends ArrayAdapter<String> {
    public MyAdapter(Context context, List<String> items) {
        super(context, 0, items);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            convertView = LayoutInflater.from(getContext()).inflate(android.R.layout.simple_list_item_1, parent, false);
        }
        TextView text = convertView.findViewById(android.R.id.text1);
        text.setText(getItem(position));

        convertView.setOnClickListener(v -> {
            // Added functionality: handle click
            Toast.makeText(getContext(), "Clicked: " + getItem(position), Toast.LENGTH_SHORT).show();
        });

        return convertView;
    }
}
