Question

我有一个应用程序，其中我收到错误＆＃34;尝试调用虚方法＆＃39; boolean java.lang.String.equalsIgnoreCase（java.lang.String）＆＃34;请解释一下

的含义和解决方案

代码： -

 String receivedResult = parseJsonResultSetFav(result);
            if (receivedResult.equalsIgnoreCase("SUCCESS")) {
                CustomerTicketDialogClass ctdc = new CustomerTicketDialogClass(getActivity(),
                        "successful", "successfully sent mail to your email id ", "ViewDetails");
                ctdc.show();
                ctdc.setCanceledOnTouchOutside(false);
            } else {
                CustomerTicketDialogClass ctdc = new CustomerTicketDialogClass(getActivity(),
                        "failure", receivedResult, "ViewDetails");
                ctdc.show();
                ctdc.setCanceledOnTouchOutside(false);
            }

Answer 1

是的，你得到NullPointerException，所以为了避免这种情况..

if(receivedResut != null && receivedResult.equalsIngnoreCase("SUCCESS"))

如何解决尝试调用虚方法＆＃39; boolean java.lang.String.equalsIgnoreCase（java.lang.String）？
