Asking the user to type the Face ID is error prone.

A better user experience is:

1. on "Faces" tab, long press an existing face.
2. a popup menu appears with menu items like "destroy face", "view face details", and "add route".
3. selecting the "add route" menu item brings up the "add route" dialog where the Face ID is pre-populated.

This issue does not duplicate #4632. #4632 would allow the user to enter the same FaceUri as an existing face, while this issue would allow the user to enter a Face ID.

Is this the implementation of this feature still ongoing? We may need this feature for #4761.

Current facelist implementation:

• short click --> go to face details
• long press --> mutlichoice for batch deletion.

I can think of two options to go with:

• Keep long press for multichoice batch deletion, but change short click to trigger a floating menu or action bar menu including "face details" and "add route" buttons.
• No more multichoice batch deletion, change long press to trigger a floating menu or action bar menu including "add route" and "delete face" buttons, short click still triggers "face details".

Apart from letting the user click on face to add route, I am also thinking of adding "add route by face id" functionality in routes list screen. In the routes list screen, when user click "+" to add a route, we show two radio buttons (faceID and faceUri) in AlertDialog for user to check, then user fills in the face ID or face Uri respectively.

Any comments?

A modern UX pattern in Android apps is using swipe actions: the user swipes left or right on the list item and triggers an action for that item. This can be used for destroying a face for example.

If swipe actions are more complicated to implement, then I have a slight preference for your second option: use long press to trigger a floating menu or similar. We lose batch deletion of multiple faces but I don't think that's a frequent action.

I am also thinking of adding "add route by face id" functionality in routes list screen

No objections.

Current design:

On Face list:

• long press to show a floating menu containing "Add Route" and "Delete"
• short click to show face details

On Route list:

• Add functionality to add route by face id.

A bug existing even before this change: after deleting the face, the user has to refresh the UI manually, otherwise the face is still shown in the list (bu logically, it's gone).
