    private int old_count = 0;

    public ExpandableListView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        if (getCount() != old_count) {
            old_count = getCount();
            params = getLayoutParams();
            params.height = getCount() * (old_count > 0 ? getChildAt(0).getHeight() : 0);
            System.out.println("params h "+params.height+" "+params);
            setLayoutParams(params);
        }

        super.onDraw(canvas);
    }
