Question

I have tried to develop retrieving the count value from soap webservices and display them to android emulator. Here I have mentioned particular textview means it is not display on my emulator. Why this is not display on my emulator. Please help me. Which line I have to change.
This is my android code:

public class RetailerActivity extends Activity {
private static final String SOAP_ACTION = "http://xcart.com/data";
private static final String METHOD_NAME = "data";
private static final String NAMESPACE = "http://xcart.com";
private static final String URL = "http://192.168.1.168:8085/XcartLogin/services/RetailerWs?wsdl";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.retrieve);
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

    envelope.setOutputSoapObject(request);

    HttpTransportSE ht = new HttpTransportSE(URL);
    try {
        ht.call(SOAP_ACTION, envelope);
        SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
        SoapPrimitive s = response;
        String str = s.toString();
        String resultArr[] = str.split("&");//Result string will split & store in an array
        TextView tv = (TextView) findViewById(R.id.textView1);
       // TextView tv = new TextView(this);

        for(int i = 0; i<resultArr.length;i++){
        tv.append(resultArr[i]+"\n\n");
       }
        setContentView(tv);

    } catch (Exception e) {
        e.printStackTrace();
    }
    }
   }

Here i have to wrote TextView tv = new TextView(this); line means the output is displayed.but i have to put dis line TextView tv = (TextView) findViewById(R.id.textView1); means the output is not display on my emulator.

Answer 1

Remove this line setContentView(tv);. I don’t seem to find it correct to use two setContentView() here.

Because you have already called the setContentView(R.layout.retrieve); in the first place and you have initialized your TextView here,

 TextView tv = (TextView) findViewById(R.id.textView1);

So,

tv.append(resultArr[i]+"\n\n"); 

alone should work. No need to set tv again.

EDIT 1

Your TextView in xml should be something like this,.

    <TextView android:id="@+id/textView1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"/>

Remove other attributes,.
