如果您想将图像从一个活动发送到另一个活动，您只需使用sqlite数据库并将图像保存在某些图像中文件夹并保存数据库中的路径，并在下一个活动中获取您最后保存的图像或使用某种索引来识别刚刚插入数据库中的图像，并在下一个活动中获取该图像。

and if you want to send an image from one activity to another activity, you just use sqlite database and save your image in some images folder and save the path in database and in next activity get the image which u have saved lastly or use some sort of index to identify the image you have just inserted in the database and get that image in your next activity.
