android - 弹出窗口内的Editext在android中显示错误的令牌错误？

Question

在我在编辑文本中输入值后，我在弹出窗口中使用编辑文本，它显示一些错误的令牌错误。有人知道请帮我解决这个问题。

我的弹出窗口编码。

 inflater1 = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                popupView = inflater1.inflate(R.layout.image_pop_up, null, true);
                pw = new PopupWindow(popupView, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, true);
                pw.setFocusable(true)
    EditText name = (EditText)popupView.findViewById(R.id.edittext1);
    pw.showAtLocation(activity.findViewById(R.id.order_page_xml), Gravity.CENTER, 0, 15);
