I need to show popup window directly above button. My button is placed inside scroll view, and popup always shown below button. Here is my code:

  private void showPopup(View view, String text) {
    if (infoPopup == null) {
        LayoutInflater layoutInflater = LayoutInflater.from(getActivity());
        View popupView = layoutInflater.inflate(R.layout.popup_credit_request_passport, null);

        infoPopup = new PopupWindow(popupView,
                ViewGroup.LayoutParams.MATCH_PARENT,
                ViewGroup.LayoutParams.WRAP_CONTENT);
        infoPopup.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

但这不行.请帮我.

推荐答案

Change Gravity to Top 并根据您的要求重置您的坐标.

Change Gravity to Top and reset your coordinates according to your requirement.

infoPopup.showAtLocation(view, Gravity.TOP, 0, (int) view.getY());
