SharedPrefManagerをandroidで更新する方法

Question

私はユーザーログインアプリケーションを作成しました。ログイン後、取得したすべてのデータをsharedPrefManagerに保存していますが、その後、私はアプリを再起動するか、ユーザの詳細を更新するたびに更新をチェックし、変更されたデータを取得するか、profile_Activity(Specific)を開くたびに更新します。ここで

は私のSharedPrefです：

public class SharedPrefManager { 

    private static SharedPrefManager mInstance; 
    private static Context mCtx; 
    private static final String SHARED_PREF_NAME = "mysharedpref12"; 
    private static final String KEY_USERNAME = "username"; 
    private static final String KEY_USER_MAIL = "usermail"; 
    private static final String KEY_USER_ID = "userid"; 
    private static final String KEY_PHONE = "userphone"; 
    private static final String KEY_NAME = "usename"; 
    private static final String KEY_PIN = "pin"; 
    private static final String KEY_SUR = "surname"; 
    private static final String KEY_ADD = "address"; 

    private SharedPrefManager(Context context) { 
     mCtx = context; 
    } 

    public static synchronized SharedPrefManager getInstance(Context context) { 
     if (mInstance == null) { 
      mInstance = new SharedPrefManager(context); 
     } 
     return mInstance; 
    } 

    public boolean userLogin(int id, int pin, String phone, String username, String mail, String name, String surname, String address/**, String catagory*/){ 

     SharedPreferences sharedPreferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE); 
     SharedPreferences.Editor editor = sharedPreferences.edit(); 

     editor.putInt(KEY_USER_ID, id); 
     editor.putInt(KEY_PIN, pin); 
     editor.putString(KEY_PHONE, phone); 
     editor.putString(KEY_USERNAME, username); 
     editor.putString(KEY_USER_MAIL, mail); 
     editor.putString(KEY_NAME, name); 
     editor.putString(KEY_SUR, surname); 
     editor.putString(KEY_ADD, address); 
     //editor.putString(KEY_CATA, catagory); 

     editor.apply(); 

     return true; 

    } 

    public boolean isLoggedIn(){ 
     SharedPreferences sharedPreferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE); 
     if (sharedPreferences.getString(KEY_USERNAME, null) != null){ 
      return true; 
     } 
      return false; 
    } 

    public boolean logOut(){ 
     SharedPreferences sharedPreferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE); 
     SharedPreferences.Editor editor = sharedPreferences.edit(); 
     editor.clear(); 
     editor.apply(); 
     return true; 
    } 

    public int getid(){ 
     SharedPreferences sharedPreferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE); 
     return sharedPreferences.getInt(KEY_USER_ID, 0); 
     //return sharedPreferences.getInt(KEY_USER_ID, Integer.parseInt(null)); 
    } 

    public int getpin(){ 
     SharedPreferences sharedPreferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE); 
     return sharedPreferences.getInt(KEY_PIN,0); 
     /*SharedPreferences sharedPreferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE); 
     return sharedPreferences.getInt(KEY_PIN, Integer.parseInt(null));*/ 
    } 

    public String getUsername(){ 
     SharedPreferences sharedPreferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE); 
     return sharedPreferences.getString(KEY_USERNAME, null); 
    } 

    public String getUserEmail(){ 
     SharedPreferences sharedPreferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE); 
     return sharedPreferences.getString(KEY_USER_MAIL, null); 
    } 

    public String getUserPhone(){ 
     SharedPreferences sharedPreferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE); 
     return sharedPreferences.getString(KEY_PHONE, null); 
    } 

    public String getName() { 
     SharedPreferences sharedPreferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE); 
     return sharedPreferences.getString(KEY_NAME, null); 
    } 

    public String getSurname() { 
     SharedPreferences sharedPreferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE); 
     return sharedPreferences.getString(KEY_SUR, null); 
    } 

    public String getAddress() { 
     SharedPreferences sharedPreferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE); 
     return sharedPreferences.getString(KEY_ADD, null); 
    } 

} 

Answer 1

私はsharedPreferenceためsaperateクラスがあります： -

1> AppPreference.java

public class AppPreference { 


    public static final String PREF_USERID = "prefUserId"; 
    public static final String PREF_FNAME = "prefFname"; 
    public static final String PREF_LNAME = "prefLname"; 
    public static final String PREF_PHONE = "prefphone"; 


    public static final void setStringPref(Context context, String prefKey, String key, String value) { 
     SharedPreferences sp = context.getSharedPreferences(prefKey, 0); 
     SharedPreferences.Editor edit = sp.edit(); 
     edit.putString(key, value); 
     edit.commit(); 
    } 

    public static final String getStringPref(Context context, String prefName, String key) { 
     SharedPreferences sp = context.getSharedPreferences(prefName, 0); 
     return sp.getString(key, ""); 
    } 

    public static final class PREF_KEY { 
     public static final String USERID = "userid"; 
     public static final String FNAME = "fname"; 
     public static final String LNAME = "lname"; 
     public static final String PHONE = "phone"; 
    } 
} 

2> LoginActivity.java

を

if (jsonObject.toString().contains(Constant.JSON_KEY.RESPONSE)) { 
         JSONObject response = jsonObject.getJSONObject(Constant.JSON_KEY.RESPONSE); 

         String userId = response.getString(Constant.JSON_KEY.ID); 
         String fname = response.getString(Constant.JSON_KEY.FNAME); 
         String lname = response.getString(Constant.JSON_KEY.LNAME); 
         String phone = response.getString(Constant.JSON_KEY.PHONE); 

         SignUpDetailsClass signUpDetailsClass = new SignUpDetailsClass(); 
         signUpDetailsClass.setId(userId); 
         signUpDetailsClass.setFname(fname); 
         signUpDetailsClass.setLname(lname); 
         signUpDetailsClass.setPhone(phone); 

         **// store data in sharedPreference** 
         AppPreference.setStringPref(context, AppPreference.PREF_USERID, AppPreference.PREF_KEY.USERID, userId); 
         AppPreference.setStringPref(context, AppPreference.PREF_FNAME, AppPreference.PREF_KEY.FNAME, fname); 
         AppPreference.setStringPref(context, AppPreference.PREF_LNAME, AppPreference.PREF_KEY.LNAME, lname); 
         AppPreference.setStringPref(context, AppPreference.PREF_PHONE, AppPreference.PREF_KEY.PHONE, phone); 
    } 

3> Profile.java最初のクラスでここ

     **// get data from sharedPreference** 
         String userId = AppPreference.getStringPref(context, AppPreference.PREF_USERID, AppPreference.PREF_KEY.USERID); 
         String strMob = AppPreference.getStringPref(context, AppPreference.PREF_PHONE, AppPreference.PREF_KEY.PHONE); 
         String strFirstName = AppPreference.getStringPref(context, AppPreference.PREF_FNAME, AppPreference.PREF_KEY.FNAME); 
         String strLastName = AppPreference.getStringPref(context, AppPreference.PREF_LNAME, AppPreference.PREF_KEY.LNAME); 

はLogin.javaために、次に優先してすべてのデータを設定し、別のクラスであるAppPreference.javaするためのものですたとえば、アプリケーションのどこにでもデータを取得できます。すべてのデータをに取得します。Profile.java

希望します。
