java.lang.ClassCastException: org.ksoap2.serialization.SoapPrimitive cannot be cast to org.ksoap2.serialization.SoapObject
提问by user2648752
I am doing soap parsing in android .These are the following steps I take while doing parsing 1) I am download ksoap2-android-assembly-2.4-jar-with-dependencies (1).jar. 2) Then I used this in this code But I am getting this error .
我正在 android 中进行肥皂解析。这些是我在解析时采取的以下步骤 1) 我正在下载ksoap2-android-assembly-2.4-jar-with-dependencies (1).jar。2）然后我在这段代码中使用了它但是我收到了这个错误。
**java.lang.ClassCastException: org.ksoap2.serialization.SoapPrimitive cannot be cast to org.ksoap2.serialization.SoapObject**
Here is my code.
这是我的代码。
package com.example.networkconnectivity;

envp.setOutputSoapObject(resultRequestSOAP);

SoapPrimitive resultsString = (SoapPrimitive)envp.getResponse();
return resultRequestSOAP.toString();
} catch (Exception e) {

}

The exception is on :
例外是：
resultRequestSOAP = (SoapObject) envp.getResponse();
Because you can't cast the response get form SoapSerializationEnvelopeinto SoapObject
因为您不能将响应形式SoapSerializationEnvelope转换为SoapObject
回答by Gene
Change this: SoapPrimitive resultsString = (SoapPrimitive)envp.getResponse();
改变这个： SoapPrimitive resultsString = (SoapPrimitive)envp.getResponse();
to
到
SoapObject resultsString = (SoapObject) envp.getResponse();
SoapObject resultsString = (SoapObject) envp.getResponse();

if your web method returns json response as json array then use
SoapObject result= (SoapObject) envelop.getResponse();
if your web method returns json response as primitive data then use
SoapPrimitive results = (SoapPrimitive)envelop.getResponse();
so for your code use
SoapObject result= (SoapObject) envelop.getResponse();
