android - ksoap 2 通信 - asynctask の結果を UI スレッドに送信して出力する

Question

Visual Studio を介して、Android ユーザーからローカルホストで実行されている C# Web サービスにログイン資格情報を送信しようとしています。SOAP 通信に KSOAP2 を使用しており、ログイン情報を Web サービスに送信して UI に出力したいと考えていました。私はそれを行うために AsyncTask を使用していますが、Web サービスから情報を取得して Android UI に出力することができませんでした。

私が間違っていたところを誰か助けてもらえますか?????

public class MainActivity extends Activity {

    EditText un,pw;
    TextView tv;
    Button test;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button test=(Button) findViewById(R.id.login);
        un = (EditText) findViewById(R.id.et_un);
        pw = (EditText) findViewById(R.id.et_pw);


            test.setOnClickListener(new View.OnClickListener(){

                @Override
                public void onClick(View v) {
                    FileAsync fleasyn= new FileAsync(null);
                    fleasyn.execute();
                    } 
                }); 
 }
}



class FileAsync extends AsyncTask<String, String, char[]> {
   public FileAsync(String quotes) 
{


}


private char[] resultstring;
private TextView tv;

@Override
protected void onProgressUpdate(String... progress) {


}

protected void onPostExecute(String unused) {
    tv.setText("Status:"+resultstring);
                System.out.println(resultstring);
}


@Override
protected char[] doInBackground(String... params) {

    final String NAMESPACE = "http://sparking.org/login";
    final String METHOD_NAME = "login";
    final String SOAP_ACTION = "http://sparking.org/login";
    final String URL = "http://localhost:63734/service.asmx";

    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;
    envelope.setOutputSoapObject(request);
    HttpTransportSE transport = new HttpTransportSE(URL);
    try {
    transport.call(SOAP_ACTION, envelope);
    SoapPrimitive resultstring = (SoapPrimitive)envelope.getResponse();

}

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

}

まず、これらの変数を割り当てる必要があります。

`final String NAMESPACE = "http://xyz.org/";`
`final String METHOD_NAME="";`
`final String SOAP_ACTION="";`
`final String URL = "http://localhost:63734/mywbservice.asmx";**strong text**`

METHOD_NAME と SOAP_ACTION を空にすることはできません。プロジェクトに必要な値は次のとおりです。

<SOAP_ACTION="http://spartansparking.org/login";>
<METHOD_NAME="login";>
<NAMESPACE="http://spartansparking.org/";>
<URL = "http://localhost:63734/parkingservice.asmx";>

WebService .NET を呼び出すために、実際に AsyncTask を使用する必要はありません。ユーザーメインスレッドを使用できます。

エミュレーターとローカルホストで作業している場合は、10.0.2.2 をローカルホストとして使用してみてください: set URL="http://10.0.2.2/parkingservice.asmx";>
