private void showOrderByView() {
// TODO Auto-generated method stub
String[] items = new String[] { "智能排序", "好评优先", "离我最近", "优惠价最低" };
LinearLayout lyt = (LinearLayout) LayoutInflater.from(getActivity())
.inflate(R.layout.test, null);
ListView list = (ListView) lyt.findViewById(R.id.listView1);
list.setSelector(new ColorDrawable(Color.TRANSPARENT));
list.setAdapter(new ListAdapter(getActivity(), items));
mPopWin = new PopupWindow(lyt, view.getWidth() / 2,
LayoutParams.WRAP_CONTENT, true);
mPopWin.setBackgroundDrawable(new BitmapDrawable());
mPopWin.showAsDropDown(lblOrderBy);
mPopWin.setOutsideTouchable(true);
mPopWin.setFocusable(true);
mPopWin.update();
}
setBackgroundDrawable方法一点要在new PopupWindow后立即调用!!
