推荐答案

由于这是您的家庭作业，因此对您来说很公平应该完成大部分工作，不是吗? :laugh:
因此，没有代码.只需将其分为几个阶段，并在继续进行之前完成其中一个即可.

从头开始:
1)设置数据库以保存图像:您将需要至少两个字段，一个ID和一个BLOB或IMAGE(取决于数据库)
2)编写代码以存储图像并进行测试.
3)编写代码以检索图像并进行测试.
4)编写代码以显示图像.
5)然后，您只需要设置一个计时器并滚动即可.

Since this is your homework, it''s only fair you should do most of the work, isn''t it? :laugh:
So, no code. Just break it into stages, and complete one before moving on.

Start from the beginning:
1) Set up your database to hold the images: you will want at least two fields, an ID, and a BLOB or IMAGE (depending on your database)
2) Write the code to store the images, and test it.
3) Write the code to retrieve an image, and test it.
4) Write the code to display an image.
5) Then all you need to do is set up a timer and scroll though.
