なぜデータを保存する前後で結果が違うのですか？

Question

私は目覚まし時計アプリを作りたいと思います。実際には、私はすべてのアラームをデータベースに入れたいと思いますが、すでにこれを行っていますが、（LogCatを介して）アラームをチェックしたいとき、私は別のアラームを取得します。お願い助けて！ mySQLiteHelper.class：

public class mySQLiteHelper extends SQLiteOpenHelper { 
    // All Static variables 
    // Database Version 
    public static final int DATABASE_VERSION = 2; 

    // Database Name 
    private static final String DATABASE_NAME = "alarms.db"; 

    // Contacts table name 
    private static final String TABLE_ALARMS = "alarms"; 

    // Contacts Table Columns names 
    private static final String KEY_ID = "id"; 
    private static final String KEY_ALARM = "alarm"; 
    private static final String KEY_NAME = "name"; 

    public mySQLiteHelper(Context context) { 
     super(context, DATABASE_NAME, null, DATABASE_VERSION); 
    } 

    // Creating Tables"create table alarms (" 
    //+ "id integer primary key," 
     //  + "alarm text," 
     // + "name text," // added a ',' 
      // + "alarmname text" + ");" 
    @Override 
    public void onCreate(SQLiteDatabase db) { 
     String CREATE_CONTACTS_TABLE = "CREATE TABLE " + TABLE_ALARMS + "(" 
       + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + KEY_ALARM + " TEXT, " 
       + KEY_NAME + " TEXT" + ")"; 
     db.execSQL(CREATE_CONTACTS_TABLE); 
    } 

    // Upgrading database 
    @Override 
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
     // Drop older table if existed 
     db.execSQL("DROP TABLE IF EXISTS " + TABLE_ALARMS); 

     // Create tables again 
     onCreate(db); 
    } 

    /** 
    * All CRUD(Create, Read, Update, Delete) Operations"," + alarm.getName() +,name 
    */ 

    // Adding new contact 
    void addAlarm(Alarm alarm) { 
     SQLiteDatabase db = this.getWritableDatabase(); 
     String sql = 
       "INSERT or replace " + 
         "INTO alarms (alarm,"+KEY_NAME+") " + 
         "VALUES("+ alarm.getAlarm() + ",'" + alarm.getName() + "')"; 
     //String sql = 
      //  "INSERT or replace INTO alarms (alarm,alarmname) VALUES("+ alarm.getAlarm() + ",'" + alarm.getName() + "')" ; 
     db.execSQL(sql); 
     db.close(); // Closing database connection 
    } 

    // Getting single contact 
    String getAlarm(String alarmname) { 
     String query = "Select * FROM " + TABLE_ALARMS + " WHERE " + KEY_NAME + " = \"" + alarmname + "\""; 
     SQLiteDatabase db = this.getReadableDatabase(); 
     Cursor cursor = db.rawQuery(query, null); 
     if (cursor.getCount()>0) 
      cursor.moveToFirst(); 
     String alarm = cursor.getString(cursor.getColumnIndex(KEY_ALARM)); 
     cursor.close(); 
     // return contact 
     return alarm; 
    } 

    // Deleting single contact 
    public void deleteAlarm(Alarm alarm) { 
     SQLiteDatabase db = this.getWritableDatabase(); 
     db.delete(TABLE_ALARMS, KEY_ID + " = ?", 
       new String[] { String.valueOf(alarm.getID()) }); 
     db.close(); 
    } 


    // Getting contacts Count 
    public int getAlarmsCount() { 
     String countQuery = "SELECT * FROM " + TABLE_ALARMS; 
     SQLiteDatabase db = this.getReadableDatabase(); 
     Cursor cursor = db.rawQuery(countQuery, null); 
     int i = cursor.getCount(); 
     cursor.close(); 

     // return count 
     return i; 
    } 
} 

Alarm.class：

public class Alarm { 
    //private variables 
    int _id; 
    String _name; 
    String _alarm; 

    // Empty constructor 
    public Alarm(String alarm,String alarmname){ 
     this._alarm = alarm; 
     this._name = alarmname; 
    } 
    // constructor 
    public Alarm(int id, String name, String alarm){ 
     this._id = id; 
     this._name = name; 
     this._alarm = alarm; 
    } 

    // constructor 
    public Alarm(String alarm){ 
     this._alarm = alarm; 
    } 
    // getting ID 
    public int getID(){ 
     return this._id; 
    } 

    // getting name 
    public String getName(){ 
     return this._name; 
    } 

    // getting phone number 
    public String getAlarm(){ 
     return this._alarm; 
    } 
} 

これは私が集合時間、addAlarmを呼び出し、初めて私のアラームを取得

Calendar calendar = Calendar.getInstance(); 
calendar.set(Calendar.MINUTE,timePicker.getCurrentMinute()); 
calendar.set(Calendar.HOUR_OF_DAY,timePicker.getCurrentHour()); 
Calendar calendar1 = Calendar.getInstance(); 
calendar1.set(Calendar.MINUTE, timePicker1.getCurrentMinute()); 
calendar1.set(Calendar.HOUR_OF_DAY,timePicker1.getCurrentHour()); 
    String alarm1 = Long.toString(calendar.getTimeInMillis()); 
        String alarm2 = Long.toString(calendar1.getTimeInMillis()); 
        Log.i("Alarm1.1",alarm1); 
        Log.i("Alarm2.1",alarm2); 
        mySQLiteHelper mySQLiteHelper = new mySQLiteHelper(MainActivity2.this); 
        Log.i("Point_version",Integer.toString(mySQLiteHelper.DATABASE_VERSION)); 
        mySQLiteHelper.addAlarm(new Alarm(alarm1,"alarm1")); 
        mySQLiteHelper.addAlarm(new Alarm(alarm2,"alarm2")); 

そして、どのようにありますしばらくすると私は警報を発する

String alarm1 = mySQLiteHelper.getAlarm("alarm1"); 
     String alarm2 = mySQLiteHelper.getAlarm("alarm2"); 
     Log.i("Alarm1.2",alarm1); 
     Log.i("Alarm2.2",alarm2); 

私はこの結果得、これを試してみましたと思います：

Alarm1.1﹕ 1459098157713 
Alarm2.1﹕ 1459098230836 
Alarm1.2﹕ 1459095666194 
Alarm2.2﹕ 1459095664808 

Answer 1

この

String CREATE_CONTACTS_TABLE = "CREATE TABLE " + TABLE_ALARMS + "(" 
      + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + KEY_ALARM + " TEXT, " 
      + KEY_NAME + " TEXT, UNIQUE ("+KEY_NAME+") ON CONFLICT REPLACE" + ")"; 
db.execSQL(CREATE_CONTACTS_TABLE); 

することにより、この

String CREATE_CONTACTS_TABLE = "CREATE TABLE " + TABLE_ALARMS + "(" 
       + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + KEY_ALARM + " TEXT, " 
       + KEY_NAME + " TEXT" + ")"; 
db.execSQL(CREATE_CONTACTS_TABLE); 

を交換し、

Answer 2

...アプリあなたを再インストール

実際に私はすべてのデータを削除することを忘れてしまいました。いくつかの文字列（アラーム）とそれらのすべてが同じ名前だった。
