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

 1     TextView noticeHeaderView;
 2     TextView headerRefreshText;
 3     ProgressBar headerRefreshPgrsb;
 4     View headerRefresh;
 5     Drawable d;
 6     if (headerRefresh.getVisibility() == View.VISIBLE) {
 7         ViewGroup.LayoutParams lp = headerRefresh.getLayoutParams();
 8         lp.height += y - startY;
 9         if (lp.height >= noticeHeaderView.getHeight() * 2) {
10             headerRefreshText.setText("松手刷新");
11             d = context.getResources().getDrawable(R.drawable.header_refresh_up);
12         }else{
13             headerRefreshText.setText("下拉刷新");
14             d = context.getResources().getDrawable(R.drawable.header_refresh_down);
15         }
16         Rect outRect = new Rect();
17         headerRefreshPgrsb.getDrawingRect(outRect);
18         d.setBounds(outRect);
19         headerRefreshPgrsb.setIndeterminateDrawable(d);
20     }
