Not sure if this should be part of v1, but it's something to think about when designing our data storage. It would also be necessary if we were to dogfood the list system such that we used it to build our own bookmarks UI.

Attached patch Testing patch (obsolete) — Splinter Review
Use this patch to get sample data that has a folder hierarchy. The main thing that still needs to be determined is how we want to display which folder the user is currently in. Do we want to do this the same way as bookmarks? In general, it seems that not many are huge fans of the way it is done there. Tagging ibarlow for input on this. Link to build with all of this in it: https://drive.google.com/file/d/0BwqqgfwYmRg4NmdkZW12YTE2NGc/edit?usp=sharing

Thanks Josh. This looks good but needs a little work too. The core interaction of tapping a folder to drill down, and tapping back is correct, but we want to build on that a little. Adding a header row with an up icon and a "back to folder-name" string, as well as a title row indicating the current folder, will help a little with wayfinding. Sorry for the crude sketch, but hopefully it's enough to keep moving ahead http://cl.ly/image/40061C1U0F0y

This uses MultiTypeCursorAdapter in a similar way that BookmarksListAdapter does. This functionality could probably be generalized into a base class (FolderListAdapter) but there is quite a bit of different functionality between the two and would take some refactoring work. Lucas, do you want me to do that in this bug, file a follow up, or is it worth it at all?

Comment on attachment 8372000 [details] [diff] [review] Pass folder to content provider and filter on query Review of attachment 8372000 [details] [diff] [review]: ----------------------------------------------------------------- Had a look at the last patch to get a better sense about the direction of things here. There's no special need to use 'folder' terminology here. You don't even need the notion of paths in the urls if you're going to track the stack of filters in PanelListAdapter anyway. In this case, filter is the equivalent of parentId in the BookmarksPanel code. So, here's roughly how this could work (let me know if you find any obvious flaw with the proposal): 1. Items in root 'folder' have a null value in their 'filter' column. The parent stack will have a single element with filter == null. 2. Folder X have url in the form of filter://SOMEFILTER 3. Children of Folder X have a SOMEFILTER value in their filter column. Tapping on Folder X will: 1. Add Folder X title and target filter (the one from the url) in the parent stack 2. Re-request the dataset with same ID but different filter (SOMEFILTER in this case) I'm using the term folder here just to be clear but I'm not sure this is the best term? I'd go with 'filter' but I'm open to suggestions. Whatever term we agree on here, it should be used consistently everywhere. For instance, this patch adds a 'filter' column to the DB schema but then uses 'folder' everywhere in the code which feels a bit confusing. ::: mobile/android/base/home/DynamicPanel.java @@ +180,4 @@ > } > > final Bundle bundle = new Bundle(); > + bundle.putString(DATASET_ID, request.datasetId); Make DatasetRequest a Parcelable and pass it in the bundle directly.

Attachment #8372003 - Flags: review?(lucasr.at.mozilla)
Let's try to stick with the simplest possible implementation (our 'MVP') without making too many assumptions around how this "could work" in the future. So, as a starting point, what we want to implement here is a way to navigate up and down dataset filters with all items using the same view type (PanelListRow). A 'filter' being any string placed in the 'filter' column in the DB that can be triggered by a special type of URL with the format filter://SOMESTRING. That's all. I'd like to get some input from margaret and mfinkle on the terminology here. I'm personally leaning towards 'filter' as general way for accessing subsets of datasets. The fact that we'll end up using it to represent 'folders' is secondary. Using 'folder' (either on the DB schema and UI code) feels too restrictive and prone to be abused for other purposes by add-on developers.

Comment 19 sounds a lot like what we were discussing at the feature work week. Using "filter" terminology and a special "filter://" URI sounded good to me, then and now. It's simple, but should allow us to get the MVP ready to go. It's also useful for more than simulating a tree hierarchy too.
Flags: needinfo?(mark.finkle)
I also like the term "filter", since it's a better way to represent what our code is actually doing. An add-on could create a folder UI using this filter functionality, but it could also do something like a "sections" UI for different sections of a news publication (for this reason I like Lucas's suggestion to let the add-on specify the icon for "folder" rows - and if they want a folder icon that matches our bookmarks UI, they could actually use a drawable:// URI to get at that).

If we are going to let add-ons define the icon for the rows, I think we should also let them define icons for the back arrow row. However, we'd have to figure out where they would specify that, since it wouldn't be part of the normal HomeProvider data. Or maybe we should just have ibarlow come up with a more generic "up" or "back" icon for that.

Attached patch Display filter up navigation (obsolete) — Splinter Review
Now displays filter links the same as other rows, which allows addons to supply their own icon for filter links. Filter link rows do not display the URL for the filter (this could have confused users). Also does not assume that filter navigation is necessarily a folder tree, simply provides back support by keeping track of a navigation stack. Currently, the back list item uses our default folder with the back button as the icon, until we decided on what to do from Comment 24.

Furthermore, load() is a layout-wide call but you only want to scope the request to the specific view that triggered this URL. I'd probably add all this code into a private method like pushFilterOnView(View v) to make this code a bit cleaner. If you what I describe above, you won't need to do any API changes to OnUrlOpenListener. Win.

Forgot to mention: please make sure you update/add in-code comments and documentation to match the new internal APIs (method signatures, the new DatasetRequest class, etc).
