dbhelper()不调用onupdate方法

我必须启动一个使用1个数据库表的应用程序(ABezoe) 我想在数据库中添加一个额外的表(ABezur)

我试图让一个类似于ABezoe的类,我得到一个错误,它无法找到第二个(ABezur)表,所以我不能写它

因此在互联网上搜索显示我需要一个类(ADbAdapter)来创建我的数据库 对于我想要连接的不同表有不同的类会很好(ABezoeAdapter,ABezurAdapter)

我已经做了一切尝试这个设置,但它仍然无法正常工作

我甚至删除了应用程序以重新安装所有内容,但仍未调用数据库的oncreate()

谁能帮助我?

logcat显示:

除此之外没什么特别的logcat

需要创建数据库的我的类ADbAdapter:

   package com.example.deceunincktechniekers;

    import android.content.Context;
    import android.database.SQLException;
    import android.database.sqlite.SQLiteDatabase;
    import android.database.sqlite.SQLiteOpenHelper;
import android.util.Log;

public class ADbAdapter {
    public static final String databasenaam = "ATribune";

    public static final int databaseversie = 2;



private static final String CREATE_TABEL_ABEZOE = "CREATE TABLE " + 
            ABezoeAdapter.databasetabel + "(" +
            ABezoeAdapter.recordnummer + " BLOB NOT NULL, " +
            ABezoeAdapter.bezoekrapportnummer + " INTEGER PRIMARY KEY AUTOINCREMENT, " +

            //**here are some lines deleted**//

            ABezoeAdapter.verzonden + " VARCHAR(1) NOT NULL );";

private static final String CREATE_TABEL_ABEZUR = "CREATE TABLE " + 
            ABezurAdapter.databasetabel + "(" +
            ABezurAdapter.recordnummer + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
            ABezurAdapter.bezoekrapportnummer + " VARCHAR(10) NOT NULL, " +
            ABezurAdapter.werknemer + " VARCHAR(3) NOT NULL, " +

            ABezurAdapter.ONBEKEND + " VARCHAR(2) NOT NULL, " +
            ABezurAdapter.totaaltijd + " VARCHAR(4) NOT NULL );";

            private Context context; 
            private DatabaseHelper DBHelper;
            private SQLiteDatabase db;


    public void DBAdapter(Context ctx)
    {
        this.context = ctx;
        this.DBHelper = new DatabaseHelper(this.context);
    }

    private static class DatabaseHelper extends SQLiteOpenHelper 
    {
        DatabaseHelper(Context context) 
        {
            super(context, databasenaam, null, databaseversie);
        }

        @Override
        public void onCreate(SQLiteDatabase db) 
        {
            db.execSQL(CREATE_TABEL_ABEZOE);  
            db.execSQL(CREATE_TABEL_ABEZUR); 
            Log.i("oncreate databases geroepen", "oncreate werkt" );
        }

        @Override
        public void onUpgrade(SQLiteDatabase db, int oldVersion, 
        int newVersion) 
        {               
            db.execSQL("DROP TABLE IF EXISTS " + ABezoeAdapter.databasetabel);
            onCreate(db);
        }
    }; 


    public ADbAdapter open() throws SQLException 
    {
        this.db = this.DBHelper.getWritableDatabase();
        return this;
    }

    public void close() 
    {
        this.DBHelper.close();
    }
}

班级ABezurAdapter:

    }

    public long startwerkuren(String bezoeknummer, int werknemer2,

        return onzedatabase.insert(databasetabel, null, cv);



    }
