     cursor.close();

} 

(получение идентификатора и текст из texfield в базу данных работает отлично, но ..)

Я пытаюсь получить значения часов и минут из TimePickerDialog и вставить в da tabase, но кажется, что он не работает.

Снимок экрана из журнала кошки:

Почему не может его увидеть столбец с именем «час»?

Добавить запятые в своем заявлении для создания базы данных

// SQL statement to create database 
    private static final String DATABASE_CREATE_SQL = "CREATE TABLE " 
      + DATABASE_TABLE + " (" + KEY_ROWID 
      + " INTEGER PRIMARY KEY AUTOINCREMENT, " + KEY_TASK 
      + " TEXT NOT NULL, " + KEY_DATE + " TEXT," + KEY_HOUR + " TEXT," 
      + KEY_MINUTE + " TEXT" + ")";
