@Override
public View getChildView(int groupPosition, int childPosition,
        boolean isLastChild, View convertView, ViewGroup parent) {

    robot = Typeface.createFromAsset(context.getAssets(), "fonts/Roboto-Light.ttf"); 
    TextView text = new TextView(context);
    text.setText(subthings[groupPosition][childPosition]);
    text.setTypeface(robot);
    text.setTextSize(15);
    text.setPadding(90, 20, 0, 20);
