How to add path and voice files to imageview in android, record the positions of path and voice, and keep the position unchanged during editing

Question

Draw a path on the picture. Voice can be added at the end of the path. Clicking the voice can also play it. When completed, the location of the path and voice will be recorded. When editing, the path and voice can be deleted and re-added. If the image is scaled, the path is also required. Follow the zoom.
