    database=new MyDatabaseHelper(this,"RE.db",null, 1);
    SQLiteDatabase db=database.getWritableDatabase();


    Cursor cursor = db.query("student", null, null, null, null, null, null);

        String name = cursor.getString(cursor.getColumnIndex("username")); 
        String age = cursor.getString(cursor.getColumnIndex("age"));
        String sex=cursor.getString(cursor.getColumnIndex("sex"));
        String id=cursor.getString(cursor.getColumnIndex("id"));
