没有这样的表中找到SQLITE错误

SQLiteOpenHelper类没有这样的表中找到SQLITE错误

public class DataDB extends SQLiteOpenHelper { 

    public static final int DATABASE_VERSION = 1; 
    public static final String DATABASE_NAME = "Datas"; 
    private static final String SQL_CREATE_ENTRIES = 
      "CREATE TABLE " + FeedEntry.TABLE_NAME + " (" + 
        FeedEntry.COLUMN_NAME_ID + " INTEGER PRIMARY KEY," + 
        FeedEntry.COLUMN_NAME_NAME + " TEXT," + 
        FeedEntry.COLUMN_NAME_DESC + " TEXT," + 
        FeedEntry.COLUMN_NAME_IMG_URL + " TEXT," + 
        FeedEntry.COLUMN_NAME_PRICE + " TEXT);"; 

    private static final String SQL_DELETE_ENTRIES = 
      "DROP TABLE IF EXISTS " + FeedEntry.TABLE_NAME; 

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

    } 

    @Override 
    public void onCreate(SQLiteDatabase sqLiteDatabase) { 
     Log.e("Syntax",SQL_CREATE_ENTRIES); 
     sqLiteDatabase.execSQL(SQL_CREATE_ENTRIES); 
    } 

    @Override 
    public void onUpgrade(SQLiteDatabase sqLiteDatabase, int i, int i1) { 
     sqLiteDatabase.execSQL(SQL_DELETE_ENTRIES); 
     onCreate(sqLiteDatabase); 
    } 

    @Override 
    public void onDowngrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
     onUpgrade(db, oldVersion, newVersion); 
    } 

}

代码中插入内容

ContentValues values = new ContentValues(); 

values.put(FeedEntry.COLUMN_NAME_ID, Integer.parseInt(oneObject.getString("id"))); 
values.put(FeedEntry.COLUMN_NAME_NAME, oneObject.getString("name")); 
values.put(FeedEntry.COLUMN_NAME_DESC, oneObject.getString("desc")); 
values.put(FeedEntry.COLUMN_NAME_IMG_URL, oneObject.getString("img_url")); 
values.put(FeedEntry.COLUMN_NAME_PRICE, oneObject.getString("price")); 

db.insert(FeedEntry.TABLE_NAME, null, values);

'no such table：category' table name not found。 –

是的，我知道。但类别表不创建。 public static final String TABLE_NAME =“category”; @IntelliJAmiya –

同样的问题，如果你卸载应用程序？并再次运行。 –

的问题是在我的代码有一个Drop Command。这就是为什么在创建表格后，它正在下降。通过删除线解决了我的问题。
