共有の設定値が空に戻ります

Question

私はサーバーから値を取得して共有設定に保存し、文字列に取り込みますが、値が空であれば誰でも何が起こっているのか分かりません。チャンネルとリンクの値を比較する方法文字列。 editor.commit();後のコードの下に使用する logcat

public class MainActivity extends Activity { 
SharedPreferences sharedpreferences; 
EditText name; 
EditText email; 
public static final String mypreference = "mypref"; 
public static final String Name = "nameKey"; 
public static final String Email = "emailKey"; 
private static String NAMESPACE = "http://telview360/"; 
private static String URL = "http://54.179.134.139/viView360Service/WebService.asmx?WSDL"; 
private static String SOAP_ACTION = "http://telview360/ImageDetails"; 
private static String METHOD_NAME = "ImageDetails"; 
String link; 
String channel; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    final Thread networkThread = new Thread() { 
     @Override 
     public void run() { 
      try { 
       SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 
       SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
       envelope.setOutputSoapObject(request); 
       HttpTransportSE ht = new HttpTransportSE(URL); 
       ht.call(SOAP_ACTION, envelope); 
       final SoapPrimitive response = (SoapPrimitive) envelope.getResponse(); 
       link = response.toString(); 

       Log.d("Web response", ":" + link); 
      } catch (Exception e) { 
       e.printStackTrace(); 
      } 
     } 
    }; 
    networkThread.start(); 
    try { 
     Thread.currentThread().sleep(100); 
    } catch (InterruptedException e) { 
     e.printStackTrace(); 
    } 


    sharedpreferences = getSharedPreferences(mypreference, 
      Context.MODE_PRIVATE); 

    SharedPreferences.Editor editor = sharedpreferences.edit(); 
    editor.putString(Name, link); 
    editor.commit(); 
    Log.d("Saved value",":"+editor.commit()); 



    channel = sharedpreferences.getString(Name, ""); 
    Log.d(" value",":"+channel); 

} 



@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.menu_main, menu); 
    return true; 
} 

}

これを試してください： -

public class MainActivity extends Activity { 
SharedPreferences sharedpreferences; 
EditText name; 
EditText email; 
public static final String mypreference = "mypref"; 
public static final String Name = "nameKey"; 
public static final String Email = "emailKey"; 
private static String NAMESPACE = "http://telview360/"; 
private static String URL = "http://54.179.134.139/viView360Service/WebService.asmx?WSDL"; 
private static String SOAP_ACTION = "http://telview360/ImageDetails"; 
private static String METHOD_NAME = "ImageDetails"; 
String link; 
String channel; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    final Thread networkThread = new Thread() { 
     @Override 
     public void run() { 
      try { 
       SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 
       SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
       envelope.setOutputSoapObject(request); 
       HttpTransportSE ht = new HttpTransportSE(URL); 
       ht.call(SOAP_ACTION, envelope); 
       final SoapPrimitive response = (SoapPrimitive) envelope.getResponse(); 
       link = response.toString(); 

sharedpreferences = getSharedPreferences(mypreference, 
      Context.MODE_PRIVATE); 

    SharedPreferences.Editor editor = sharedpreferences.edit(); 
    editor.putString(Name, link); 
    editor.commit(); 
    Log.d("Saved value",":"+editor.commit()); 



    channel = sharedpreferences.getString(Name, ""); 
    Log.d(" value",":"+channel); 

       Log.d("Web response", ":" + link); 
      } catch (Exception e) { 
       e.printStackTrace(); 
      } 
     } 
    }; 
    networkThread.start(); 
    try { 
     Thread.currentThread().sleep(100); 
    } catch (InterruptedException e) { 
     e.printStackTrace(); 
    } 




} 



@Override
