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() * ) {
             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);
     }
