我创建一个日历和一个点击事件在一天打开一个列表与时间。如何在特定日期添加日历事件与sq lite数据库在android这里是创建日历的代码在网格上查看和单击带静态的日期代码添加事件。

答案 0 :(得分：1)
也许你可以试试这个。 SQLiteDatabase.execSQL，因此您可以输入原始SQL查询。
mDb.execSQL("INSERT INTO "+DATABASE_TABLE+" VALUES (null, datetime()) ");
或java日期时间功能：
// set the format to sql date time
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date = new Date();
ContentValues initialValues = new ContentValues();
initialValues.put("date_created", dateFormat.format(date));
long rowId = mDb.insert(DATABASE_TABLE, null, initialValues);
