updating and deleting row in listview

I know the question is not new, but all the other examples I found here didnt work. Thats why I am writing to you.

I created a book application, where you can save bookdata from googlebooks and can save the data into an sqlite db. The bookdata will be displayed in a listview. If you click on a row, all the data of the row will be displayed in EdittExts in another activity - Looks like Detailed book view. Some example pictures: Listview ; detailed bookview

Now I want to give the possibility to the user to edit these bookinfos. I implemented some code to update and delte the info and I get the info from the Logcat, that the Db is created but when I go back to the ListView no Data is updated or deleted.

I used a video called "Android Studio Tutorial - 37 - Update Database" from youtube to convert for my solution

Maybe you can help me.

Following my code for the Book Info:

    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_book_info);
    bookDBHelper = new BookDBHelper(this);
    Typeface myTypeface = Typeface.createFromAsset(getAssets(), "Lobster.ttf");
    TextView myTextView = (TextView) findViewById(R.id.yourbookinfo);
    myTextView.setTypeface(myTypeface);

    btn_update = (Button) findViewById(R.id.button_update);

    Intent intent = getIntent();

    String secret_title = intent.getStringExtra(BookDataListActivity.EXTRA_MSG1);
    Secret_editText_title = (EditText) findViewById(R.id.secret_edittext_title);
    Secret_editText_title.setText(secret_title);

    String book_title = intent.getStringExtra(BookDataListActivity.EXTRA_MSG1);
    passedbooktitle = (EditText) findViewById(R.id.passed_booktitle);
    passedbooktitle.setText(book_title);

    String book_author = intent.getStringExtra(BookDataListActivity.EXTRA_MSG2);
    passedbookauthor = (EditText) findViewById(R.id.passed_bookauthor);
    passedbookauthor.setText(book_author);

    String book_date = intent.getStringExtra(BookDataListActivity.EXTRA_MSG3);
    passedbookdate = (EditText) findViewById(R.id.passed_bookdate);
    passedbookdate.setText(book_date);

    String book_rating = intent.getStringExtra(BookDataListActivity.EXTRA_MSG4);
    passedbookrating = (EditText) findViewById(R.id.passed_bookrating);
    passedbookrating.setText(book_rating);

    String book_shelf = intent.getStringExtra(BookDataListActivity.EXTRA_MSG5);
    passedbookshelf = (EditText) findViewById(R.id.passed_bookshelf);
    passedbookshelf.setText(book_shelf);

}


    public void updateBookInfo(View view){
    bookDBHelper = new BookDBHelper(getApplicationContext());
    sqLiteDatabaseBooks = bookDBHelper.getWritableDatabase();

    secret_editText_titel = Secret_editText_title.getText().toString();

    String booktitle, bookauthor, bookdate, bookrating, bookshelf;
    booktitle = passedbooktitle.getText().toString();
    bookauthor = passedbookauthor.getText().toString();
    bookdate = passedbookdate.getText().toString();
    bookrating = passedbookrating.getText().toString();
    bookshelf = passedbookshelf.getText().toString();
    int count = bookDBHelper.updateEditedBookInfo(secret_editText_titel,
            booktitle,bookauthor, bookdate, bookrating, bookshelf, sqLiteDatabaseBooks);
    Toast.makeText(getApplicationContext(), count+" book updated", Toast.LENGTH_LONG).show();
    finish();

}
    }
public void deleteBook(View view){
    bookDBHelper = new BookDBHelper(getApplicationContext());
    sqLiteDatabaseBooks = bookDBHelper.getWritableDatabase();
    bookDBHelper.deleteBookInformation(secret_editText_titel, sqLiteDatabaseBooks);
    Toast.makeText(getBaseContext(), "Book deleted", Toast.LENGTH_LONG).show();
}

}

And for my BookDBHelper:

    public int updateEditedBookInfo(String old_title, String new_title, String new_author,
                                 String new_date, String new_rating,
                                 String new_shelf, SQLiteDatabase sqLiteDatabase){
    ContentValues contentValues = new ContentValues();
    contentValues.put(BookContent.NewBookInfo.BOOK_TITLE, new_title);
    contentValues.put(BookContent.NewBookInfo.BOOK_AUTHOR, new_author);
    contentValues.put(BookContent.NewBookInfo.BOOK_DATE, new_date);
    contentValues.put(BookContent.NewBookInfo.BOOK_RATING, new_rating);
    contentValues.put(BookContent.NewBookInfo.BOOK_SHELF, new_shelf);

    String selection = BookContent.NewBookInfo.BOOK_TITLE + " = ?";
    String [] selection_args = {old_title};
    int count =  sqLiteDatabase.update(BookContent.NewBookInfo.TABLE_NAME_BOOKS, contentValues, selection, selection_args);
    return count;
}
