Android的sqlite問題

Question

我讀了幾本教程和一本書中的sqlite部分，並應用它，它工作得很好。現在我搞砸了它，試圖理解它，但現在它只會迫使每一次關閉，我不知道爲什麼。我已經一次又一次地結束了我的代碼，但也許我找不到問題，因爲我一般都是新手到sqlite /數據庫。任何幫助，將不勝感激：

public class Events extends Activity { 

private TextView tv; 
private DataHelper dh; 
/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    tv = new TextView(this); 
    dh = new DataHelper(this); 
    dh.deleteAll(); 
    //dh.addEvent("James"); 
    //Cursor c = dh.getEvent(); 
    //startManagingCursor(c); 
    //tv.setText(dh.showEvent(c)); 
    setContentView(tv); 
} 

}

public class EventsData extends SQLiteOpenHelper { 

private static final String DATABASE_NAME = "events.db"; 
private static final int DATABASE_VERSION = 1; 
private static final String DATABASE_CREATE = "CREATE TABLE" + TABLE_NAME + "(" + TITLE + " TEXT)"; 
private static final String DATABASE_UPGRADE = "DROP TABLE IF EXISTS " + TABLE_NAME; 

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

@Override 
public void onCreate(SQLiteDatabase db) { 
    // TODO Auto-generated method stub 
    db.execSQL(DATABASE_CREATE); 
} 

@Override 
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
    // TODO Auto-generated method stub 
    db.execSQL(DATABASE_UPGRADE); 
    onCreate(db); 
} 

}

public class DataHelper { 

private Context context; 
private SQLiteDatabase db; 
private EventsData eventsData; 

public DataHelper(Context context) { 
    this.context = context; 
    eventsData = new EventsData(this.context); 
} 

public void addEvent(String name) { 
    db = eventsData.getWritableDatabase(); 
    ContentValues cv = new ContentValues(); 
    cv.put(TITLE, name); 
    db.insertOrThrow(TABLE_NAME, null, cv); 
} 

}

註釋掉的addEvent（）將運行應用程序很好，但一旦我取消它，它迫使關閉。

快速拍攝：CREATE TABLE之後沒有空間。

您可以檢查錯誤消息的logcat。它會告訴你什麼是造成這種力量關閉。使用logcat進行調試的鏈接Debugging in Android using Eclipse
