    private static final String SCRIPT_CREATE_DATABASE =

                    + DRINK_COLOR + " TEXT, " + DRINK_TYPE + " TEXT, "

                    + TIME_5 + " TEXT);";

我不断收到错误“表 MYDATABASE_TABLE 没有名为 T4 的列”显然，我有一个名为 TIME_4 的列，它是“T4”的变量名

然后我在此处插入值：

public long insert(String name, String category, String color, String type, String ingredient1,
                        String ingredient2, String ingredient3, String ingredient4, String ingredient5,
                        String ingredient6, int time1, int time2, int time3, int time4, int time5){

        ContentValues contentValues = new ContentValues();
        contentValues.put(DRINK_NAME, name);
        contentValues.put(DRINK_CATEGORY, category);
        contentValues.put(DRINK_COLOR, color);
        contentValues.put(DRINK_TYPE, type);
        contentValues.put(INGREDIENT_1, ingredient1);
        contentValues.put(INGREDIENT_2, ingredient2);
        contentValues.put(INGREDIENT_3, ingredient3);
        contentValues.put(INGREDIENT_4, ingredient4);
        contentValues.put(INGREDIENT_5, ingredient5);
        contentValues.put(INGREDIENT_6, ingredient6);
        contentValues.put(TIME_1, time1);
        contentValues.put(TIME_2, time2);
        contentValues.put(TIME_3, time3);
        contentValues.put(TIME_4, time4);
        contentValues.put(TIME_5, time5);
        //  contentValues.put(TIME_6, time6);

        return sqLiteDatabase.insert(MYDATABASE_TABLE, null, contentValues);
    }

谁能告诉我我做错了什么？我是 SQLite 的新手

改变

  + TIME_3 + " TEXT, " + TIME_4 + "TEXT, "

到

+ TIME_3 + " TEXT, " + TIME_4 + " TEXT, "

因为你忘记在TIME_4 和之间放置空格TEXT,
