      }); 

      VolleySingleton.getInstance(getApplicationContext()).addToRequestQueue(jsonObjectRequest); 
     } 
    } 
} 

In der Antwort Nach Erhalt der Erfolgsmeldung möchte ich die bearbeiteten Details in den entsprechenden Eingabefeldern speichern bitte helfen Sie. Nach der Erfolgsmeldung gehe ich zum Hauptbildschirm über und ich komme wieder zu diesem Bildschirm, der nur die vorherigen Details zeigt.

Answer 1

möchten Sie Daten nach dem Download aus dem Netzwerk speichern oder nachdem eine Bearbeitung in Textfelder bearbeitet wurde ??

1. wenn aus dem Netzwerk hinzufügen, einige Methodenausführung Anweisung in Code speichern, wo Sie Daten herunterladen

   if (json_status.equalsIgnoreCase("Success")){ 
          Toast.makeText(getApplicationContext(), "changed parent details successfully", Toast.LENGTH_SHORT).show(); 
   
   
          // here you have successful received data so u can map them to edit text or save in shared prefs 
          // add method to save data here 
          saveData(response); 
   
          startActivity(new Intent(getApplicationContext(),ActivityHome.class)); 
         } 
   
   
   private void saveData(JSONObject response) { 
   
       // use JSon response object save here to shared preferences 
       // see how to load data from json object 
       // https://processing.org/reference/JSONObject_getString_.html 
   
       SharedPreferences sharedPreferences = getSharedPreferences(AppConstants.OOSH_PREFERENCES, Context.MODE_PRIVATE); 
   
       sharedPreferences.putString(....).apply; 
   
   
       // or set edit text controls with JSon data 
   } 
   

2. erfolgreich war zu speichern Bearbeiten von Textänderungen, die Sie haben zwei Möglichkeiten:

   • add Um die Schaltfläche zum Speichern zu speichern (Sie haben eine), und klicken Sie auf den Listener mit der Methode zum Speichern der Daten:

     btnSave = (CustomButton) findViewById(R.id.btn_save_parent); 
     btnSave.setOnClickListener(new View.OnClickListener() { 
         @Override 
         public void onClick(View v) { 
          saveData(v); 
         } 
     }); 
     
     
     private void saveData(View view) { 
         // get root view 
         View rootView = view.getRootView(); 
         // find edit text widget on root view 
         EditText etFirstName = (EditText) rootView.findViewById(R.id.edit_first_name); 
         // get string from edit text widget 
         String firstName = etFirstName.getString.toString(); 
     
         // get shared preferences 
         SharedPreferences sharedPreferences = getSharedPreferences(AppConstants.OOSH_PREFERENCES, Context.MODE_PRIVATE); 
         // save to shared prefs firstName wher NAME_KEY is string to identified your saved data for later use - to load 
         sharedPreferences.putString(NAME_KEY,firstName).apply; 
     
     } 
     
     
     private void loadDataFromSharedPredferences(View view) { 
         // get shared preferences 
         SharedPreferences sharedPreferences = getSharedPreferences(AppConstants.OOSH_PREFERENCES, Context.MODE_PRIVATE); 
         // load data from shared prefs firstName wher NAME_KEY is string to identified data to load 
         String firstName = sharedPreferences.getString(NAME_KEY,firstName); 
         // get root view 
         View rootView = view.getRootView(); 
         // find edit text widget on root view 
         EditText etFirstName = (EditText) rootView.findViewById(R.id.edit_first_name); 
         // set string to edit text widget 
         etFirstName.setText(firstName);   
     } 
     

   • auf Zuhörer Textänderung für EditText Widgets hinzufügen

ps. Sie müssen klarstellen - schreiben Sie eine genaue Schritte von dem, was Sie tun möchten, erreichen

• Daten aus dem Netzwerk laden? dann speichern?
• oder Wunschdatum speichern?
• oder Ergebnisdaten speichern?

Answer 2

alles geschieht hier:

... 
if (json_status.equalsIgnoreCase("Success")){ 
    Toast.makeText(getApplicationContext(), "changed parent details successfully", Toast.LENGTH_SHORT).show(); 
    startActivity(new Intent(getApplicationContext(),ActivityHome.class)); 
} 
... 

sobald Sie haben eine Erfolgsantwort die bearbeiteten Werte auf die Einstellungen speichern, zum Beispiel etFirstName, speichern sie neuen Wert auf die entsprechende Präferenz ist:

... 
if (json_status.equalsIgnoreCase("Success")){ 
    Toast.makeText(getApplicationContext(), "changed parent details successfully", Toast.LENGTH_SHORT).show(); 
    editor.putString(AppConstants.PARENT_FNAME, parentFirstName); 
    editor.apply(); //don't forget this 
    startActivity(new Intent(getApplicationContext(),ActivityHome.class)); 
} 
... 

wie Sie den Editor erstellen, aber nicht verwenden.
