Drawable(5)关于从资源文件构造的Drawable不显示

要给它设置个bounds才可以

    TextView noticeHeaderView;
    TextView headerRefreshText;
    ProgressBar headerRefreshPgrsb;
    View headerRefresh;
    Drawable d;
    if (headerRefresh.getVisibility() == View.VISIBLE) {
        ViewGroup.LayoutParams lp = headerRefresh.getLayoutParams();
        lp.height += y - startY;
        if (lp.height >= noticeHeaderView.getHeight() * 2) {
            headerRefreshText.setText("松手刷新");
            d = context.getResources().getDrawable(R.drawable.header_refresh_up);
        }else{
            headerRefreshText.setText("下拉刷新");
            d = context.getResources().getDrawable(R.drawable.header_refresh_down);
        }
        Rect outRect = new Rect();
        headerRefreshPgrsb.getDrawingRect(outRect);
        d.setBounds(outRect);
        headerRefreshPgrsb.setIndeterminateDrawable(d);
    }
