这张表有什么问题吗？

public void onCreate(SQLiteDatabase db) {
        String CREATE_CONTACTS_TABLE = "CREATE TABLE " + TABLE_CONTACTS + "("
                + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT," + KEY_FIRST_NAME + " TEXT,"
                + KEY_LAST_NAME + " TEXT," + KEY_MOB_NO + " TEXT,"
                + KEY_HOME_NO + " TEXT," + KEY_WORK_NO + " TEXT,"
                + KEY_HOME_ADDR + " TEXT," + KEY_EMAIL_ADDR + " TEXT,"
                + KEY_WORK_ADDR + " TEXT," + KEY_NOTES + " TEXT" + ");";
        db.execSQL(CREATE_CONTACTS_TABLE);

我的 logcat 说没有列。知道为什么会这样吗？

尝试卸载并再次运行该应用程序。可能是您在定义中添加了更多列，并且数据库已经安装，因此没有添加新列。onCreate方法仅在最初安装数据库时运行一次。它永远不会再次运行。当您需要升级时，有一个单独的方法onUpgrade- 但当您实际发布新版本时应该使用它。
