Android Sqlite約束失敗

下面是我在Android中使用ContentValues插入的值。雖然插入值我得到約束失敗Android Sqlite約束失敗

  ContentValues values = new ContentValues(); 
    String time = hour_ + ":" + minute_; 
    String date = day_ + "/" + month_ + "/" + year_; 
    EditText task = (EditText) findViewById(R.id.taskDetail); 
    values.put(ToDoDatabase.TASK, task.getText().toString()); 
    values.put(ToDoDatabase.TASK_TIME, time); 
    values.put(ToDoDatabase.TASK_DATE, date); 
    values.put(ToDoDatabase.TASK_NAME_FORMAT_DATE, 
      timeFormat.format(dateFormat.parse(date))); 
    toDoDatabase.insert(ToDoDatabase.TABLE_NAME, null, values);

下面給出的是從我的子類SqliteOpenHelper代碼。

static final String DATABASE_NAME = "ToDo"; 
static final int DATABSE_VERSION = 1; 
static final String ROW_ID = "_id"; 
static final String TASK = "task"; 
static final String TASK_TIME = "task_time"; 
static final String TASK_DATE = "task_date"; 
static final String TASK_STATUS = "task_status"; 
static final String TASK_NAME_FORMAT_DATE = "task_name_format_date"; 
static final String TABLE_NAME = "ToDoTable"; 

static final String CREATE_TABLE = "CREATE TABLE " + TABLE_NAME + " (" 
     + ROW_ID + " INTEGER AUTOTINCREMENT PRIMARY KEY NOT NULL , " + TASK 
     + " VARCHAR(500) NOT NULL , " + TASK_TIME 
     + " VARCHAR(20) NOT NULL , " + TASK_DATE + " DATE NOT NULL , " 
     + TASK_STATUS + " BOOLEAN DEFAULT 'FALSE' , " 
     + TASK_NAME_FORMAT_DATE + " VARCHAR(100) NOT NULL);"; 

public ToDoDatabase(Context context) { 
    super(context, DATABASE_NAME, null, DATABSE_VERSION); 
} 

@Override 
public void onCreate(SQLiteDatabase db) { 
    // TODO Auto-generated method stub 
    try { 
     db.execSQL(CREATE_TABLE); 
     Log.d("Result", "Success"); 
    } catch (Exception ex) { 
     Log.d("Result", "Fail"); 
    } 
}

問題是，我無法找出約束失敗的原因。的logcat的輸出是

可能是你在一個非null列中插入一個'null'值？同樣在你的表格定義中，我看到'AUTOTINCREMENT'，一個錯字？ –

是的，AUTOTINCREMENT是問題。你必須寫AUTOINCREMENT。 – Ranjit

你有AUTOTINCREMENT一個錯字。如果我是你，我會使用像ORMLite或Greendao這樣的OR映射器，從而節省構建查詢的所有麻煩。
