       } 
      }); 

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

在响应中获取成功消息后，我希望将编辑的详细信息保存在各自的编辑文本字段中，请帮助。 成功消息后，我通过意向移动到主屏幕，然后回到此屏幕，它仅显示以前的详细信息。更改参数后在edittext字段中存储编辑的值

你想从网络下载或在编辑文本字段编辑后保存数据？

如果从网络添加一些保存在那里你下载数据成功

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 
}

保存编辑文本改变代码方法执行的语句，你有两个选择：

加以布局保存按钮（你有一个）按钮和设置点击监听器与方法来保存数据：

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);   
}

添加文本更改侦听的EditText小部件

PS。你需要澄清 - 写一个你想要做什么的确切步骤

从网络加载数据？然后保存？
或保存请求日期？
或保存结果数据？

我想要在编辑文本字段中更改文本后保存数据，您可以显示一个编辑文本字段请 – ajay110125

@ ajay110125 - 请参阅编辑 – ceph3us

一切都发生在这里：

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

一旦你有一个成功响应节省的喜好编辑的值，例如etFirstName，将其保存为新的值对应的偏好：

... 
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)); 
} 
...

任何你创建编辑器的方式，但不使用它。
