android - SoapObject 的 GetProperty 中的 NullPointer 异常

Question

我试图执行肥皂的返回，但它不会在 getproperty 中显示错误。

我尝试了两种方法。

1-

SoapObject obj, obj1;
obj = (SoapObject) soapEnvelope.getResponse();
obj1 = (SoapObject) obj.getProperty("STRUCTSTK");

desc.setText(obj1.getProperty(1).toString());
prcrev.setText(String.format(obj1.getProperty(12).toString(), 0.00).toString());
saldo1.setText(obj1.getProperty(10).toString());

2-

SoapObject obj, obj1;
obj = (SoapObject) soapEnvelope.getResponse();
obj1 = (SoapObject) obj.getProperty("STRUCTSTK");

desc.setText(obj1.getProperty("DESCPROD").toString());
prcrev.setText(String.format(obj1.getProperty("NPRCREV").toString(), 0.00).toString());
saldo1.setText(obj1.getProperty("LJ25GERAL").toString());

两者都不起作用并NullPointerException显示desc.settext...

任何人都可以帮助我吗？

谢谢
