Android implements image region clipping

What we do today is to realize the region clipping function of the picture. Due to the needs of project functions, the author needs to read PDF documents and cut "pictures" on a page (a page is understood as a picture). The author is not familiar with this aspect, so I have to check the information on the Internet. After that, the author found that Android can realize the cutting and scaling functions of pictures by calling the system photo album and taking pictures.

This process is like uploading a avatar in an application and adjusting the avatar. Now make a record and share.

Ok！ A simple image clipping function is completed. The complete source code: Android implements the image clipping function
