Java 如何删除SQLite数据库中的条目？

我试图使DeleteEvent（）生效，但无效。我需要在哪里更改代码

这是一个Android Studio java代码

public class DBStructure {enter code here
    public static final String DB_NAME =    "EVENTS_DB";
    public static final int DB_VERSION = 1;
    public static final String EVENT_TALE_NAME = "eventstable";
    public static final String EVENT = "event";
        public static final String TIME = "time";
    public static final String DATE = "date";
    public static final String MONTH = "month";
    public static final String YEAR = "year";

}

这是我的DeleteEvent（）

使用

delete（）

方法不需要

ContentValues

：

public void DeleteEvent(String event, String time, String date, String month, String year, SQLiteDatabase database){
    database.delete(
        DBStructure.EVENT_TALE_NAME, 
        DBStructure.EVENT + " = ? AND " + DBStructure.TIME + " = ? AND " + DBStructure.DATE + " = ? AND " + 
        DBStructure.MONTH + " = ? AND " + DBStructure.YEAR + " = ?",
        new String[] {event, time, date, month, year}
    );
}

在第二个参数中，您构造WHERE子句，3d以字符串数组的形式包含将替换占位符的参数

？

您能显示DeleteEvent（）的使用代码吗？

public void DeleteEvent(String event, String time, String date, String month, String year, SQLiteDatabase database){
    database.delete(
        DBStructure.EVENT_TALE_NAME, 
        DBStructure.EVENT + " = ? AND " + DBStructure.TIME + " = ? AND " + DBStructure.DATE + " = ? AND " + 
        DBStructure.MONTH + " = ? AND " + DBStructure.YEAR + " = ?",
        new String[] {event, time, date, month, year}
    );
}
