Hack: use getView to check disabled item logic and inflate view with another layout. isEnabled is still usefull.

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = (LayoutInflater) mContext
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View row;

    if (mListItem[position].isEnabled() == false) row = inflater.inflate(
            R.layout.list_row_disabled, null);
    else {
        row = inflater.inflate(R.layout.list_row, null);
        // set right extensible icon
        if (mListItem[position].getType()) {
            ImageView ic_arrow = (ImageView) row.findViewById(R.id.list_row_arrow);
            ic_arrow.setImageResource(R.drawable.ic_arrow_right);
        }
    }
    // set left icon
    ImageView ic_item = (ImageView) row.findViewById(R.id.list_row_icon);
    ic_item.setImageResource(mListItem[position].getIcon());
    // blend icon if item is disabled
    if (mListItem[position].isEnabled() == false) 
        ic_item.setColorFilter(0x99D0D0D0,Mode.SRC_ATOP); // make icons look grayer 

    // set title text
    TextView txvTitle = (TextView) row.findViewById(R.id.list_row_title);
    txvTitle.setText(mListItem[position].getTitle());

    return row;
}

@Override
public boolean isEnabled(int position) {
    return mListItem[position].isEnabled();
}
