Book上课implements Serializable并在OnItemClickListener您的listView活动中使用

listView.setOnItemClickListener(new OnItemClickListener()
    {
        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1,int position, long arg3)
        {
            Book clickedBook = books.get(position);
            Intent intent = new Intent(context, NextActivity.class);
            intent.putExtra("SELECTED_BOOK", clickedBook);
            context.startActivity(intent);
        }
    });

而在NextActivity

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Bundle extras = getIntent().getExtras();
        Book selectedBook = (Book)extras.get("SELECTED_BOOK");
    }
