IMHO, it's easier to use a custom adapter:

class CustomAdapter extends ArrayAdapter {
    Context context;

    public CustomAdapter(Context context, int resourceId, List items) {
        super(context, resourceId, items);
        this.context = context;
    }

    private class ViewHolder {
        TextView txt;
        View layout;
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder = null;
        CustomRowItem rowItem = getItem(position);

        LayoutInflater mInflater = (LayoutInflater) context
            .getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
        if (convertView == null) {
            convertView = mInflater.inflate(R.layout.сustom_list, null);
            holder = new ViewHolder();
            holder.txt = (TextView) convertView.findViewById(R.id.сustom_list_txt);
            holder.layout = convertView.findViewById(R.id.сustom_list_layout);
            convertView.setTag(holder);
        } else
            holder = (ViewHolder) convertView.getTag();

        holder.txt.setText(rowItem.getText());
        if(rowItem.isChecked())
            holder.layout.setBackgroundColor(-16720999); //color for checked
        else
            holder.layout.setBackgroundColor(0); //color for unchecked

        return convertView;
    }

}

class CustomRowItem {
    private boolean value;
    private String text;

    public CustomRowItem(String text, boolean value) {
        this.text = text;
        this.value = value;
    }
    public boolean isChecked() {
        return value;
    }
    public void setChecked(boolean checked) {
        value = checked;
    }
    public String getText() {
        return text;
    }
    void setText(String text) {
        this.text = text;
    }
} 

сustom_list.xml :

How use:

public class ExampleAct extends Activity {

    final List list = new ArrayList();
    CustomAdapter adapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.example);

        ListView listView=(ListView)findViewById(R.id.listView);

        adapter = new CustomAdapter(this, R.layout.сustom_list, list);
        listView.setAdapter(adapter);

        list.add(new CustomRowItem("unchecked item",false));
        list.add(new CustomRowItem("checked item",true));

        adapter.notifyDataSetChanged();

        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { //unchecked on click
            @Override
            public void onItemClick(AdapterView parent, View itemClicked, int index, long id) {
                if(list.get(index).isChecked()) {
                    list.get(index).setChecked(false); //uncheck
                    adapter.notifyDataSetChanged();
                } else {
                    // other actions
                }

        });

        listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() { //checked on long click
            @Override
            public boolean onItemLongClick(AdapterView parent, View itemClicked, int index, long id) {
                list.get(index).setChecked(true); //check
                adapter.notifyDataSetChanged();
                return true; // or false for calling context menu
            }
        });

    }
