我如何设置对象的arraylist - Android Content Provider

Question

如何在对象的arraylist上执行bulkInsert？

我有一个Book的arraylist，我想使用Content Provider的bulkInsert函数批量插入一个Books列表;

这是书的arraylist：

    private ArrayList<Book> bookList;

here is my code where I try to do bulkinsert
// insert data into database
public void insertData() {

   ContentValues bookValues = new ContentValues();


   for(Book book: bookList){
       bookValues = new ContentValues();
       bookValues.put(BookContract.BookEntry.COLUMN_ID, Book.getBook_id());
       bookValues.put(BookContract.BookEntry.COLUMN_TITLE, Book.getTitle());
       bookValues.put(BookContract.BookEntry.COLUMN_OVERVIEW, Book.getDescription());


   }


   // Finally, insert Book data into the database.
       getActivity().getContentResolver().insert(
               BookContract.BookEntry.CONTENT_URI, bookValues
       );



   }
