It seems you don't have an adapter. In an adapter you can modify your list (add or remove item, change text, color etc)

If you want to make your own list you will have to make your own adapter for your list. You can remove items in the adapter.

 public View getView(final int position, View view, ViewGroup parent) {
    LayoutInflater inflater = LayoutInflater.from(context);
    View rowView = inflater.inflate(resource, parent, false);

    TextView textView = rowView.findViewById(R.id.textView);
    CheckBox checkBox = rowView.findViewById(R.id.checkBox);

    textView.setText(dataSet.get(position).myText);
    checkBox.setChecked(dataSet.get(position).myBool);

    checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
            // You can remove item here
        }
    });

    return rowView;
}

For this you need your own data type.

Here a project with an example: https://github.com/Asuki/SimpleListView

You also have to add the remove items to the other one list (maybe from the adapter)
