The idea here is: Everytime we get hold of a new version of a post, we
update everything about that post everywhere.
This makes the distincion between different event types unnecessary, as
everythng is just a `StatusChangedEvent`.
The main benefit is that posts should be up-to-date more often, which is
important considering there is now editing and #3413
* Unmodified output from "Convert Java to Kotlin" on NotificationsFragment.java
* Bare minimum changes to get this to compile and run
- Use `lateinit` for `eventhub`, `adapter`, `preferences`, and `scrolllistener`
- Removed override for accountManager, it can be used from the superclass
- Add `?.` where non-nullity could not (yet) be guaranteed
- Remove `?` from type lists where non-nullity is guaranteed
- Explicitly convert lists to mutable where necessary
- Delete unused function `findReplyPosition`
* Remove all unnecessary non-null (!!) assertions
The previous change meant some values are no longer nullable. Remove the
non-null assertions.
* Lint ListStatusAccessibilityDelegate call
- Remove redundant constructor
- Move block outside of `()`
* Use `let` when handling compose button visibility on scroll
* Replace a `requireNonNull` with `!!`
* Remove redundant return values
* Remove or rename unused lambda parameters
* Remove unnecessary type parameters
* Remove unnecessary null checks
* Replace cascading-if statement with `when`
* Simplify calculation of `topId`
* Use more appropriate list properties and methods
- Access the last value with `.last()`
- Access the last index with `.lastIndex`
- Replace logical-chain with `asRightOrNull` and `?.`
- `.isNotEmpty()`, not `!...isEmpty()`
* Inline unnecessary variable
* Use PrefKeys constants instead of bare strings
* Use `requireContext()` instead of `context!!`
* Replace deprecated `onActivityCreated()` with `onViewCreated()`
* Remove unnecessary variable setting
* Replace `size == 0` check with `isEmpty()`
* Format with ktlint, no functionality changes
* Convert NotifcationsAdapter to Kotlin
Does not compile, this is the unchanged output of the "Convert to Kotlin"
function
* Minimum changes to get NotificationsAdapter to compile
* Remove unnecessary visibility modifiers
* Use `isNotEmpty()`
* Remove unused lambda parameters
* Convert cascading-if to `when`
* Simplifiy assignment op
* Use explicit argument names with `copy()`
* Use `.firstOrNull()` instead of `if`
* Mark as lateinit to avoid unnecessary null checks
* Format with ktlint, whitespace changes only
* Bare minimum necessary to demonstrate paging in notifications
Create `NotificationsPagingSource`. This uses a new `notifications2()` API
call, which will exist until all the code has been adapted. Instead of
using placeholders,
Create `NotificationsPagingAdapter` (will replace `NotificationsAdapater`)
to consume this data.
Expose the paging source view a new `NotificationsViewModel` `flow`, and
submit new pages to the adapter as they are available in
`NotificationsFragment`.
Comment out any other code in `NotificationsFragment` that deals with
loading data from the network. This will be updated as necessary, either
here, or in the view model.
Lots of functionality is missing, including:
- Different views for different notification types
- Starting at the remembered notification position
- Interacting with notifications
- Adjusting the UI state to match the loading state
These will be added incrementally.
* Migrate StatusNotificationViewHolder impl. to NotificationsPagingAdapter
With this change `NotificationsPagingAdapter` shows notifications about a
status correctly.
- Introduce a `ViewHolder` abstract class that all Notification view holders
derive from. Modify the fallback view holder to use this.
- Implement `StatusNotificationViewHolder`. Much of the code is from the
existing implementation in the `NotificationAdapater`.
- The original code split the code that binds values to views between the
adapter's `bindViewHolder` method and the view holder's methods.
In this code, all of the binding code is in the view holder, in a `bind`
method. This is called by the adapter's `bindViewHolder` method. This keeps
all the binding logic in the view holder, where it belongs.
- The new `StatusNotificationViewHolder` uses view binding to access its views
instead of `findViewById`.
- Logically, information about whether to show sensitive media, or open
content warnings should be part of the `StatusDisplayOptions`. So add those
as fields, and populate them appropriately.
This affects code outside notification handling, which will be adjusted
later.
* Note some TODOs to complete before the PR is finished
* Extract StatusNotificationViewHolder to a new file
* Add TODO for NotificationViewData.Concrete
* Convert the adapter to take NotificationViewData.Concrete
* Add a view holder for regular status notifications
* Migrate Follow and FollowRequest notifications
* Migrate report notifications
* Convert onViewThread to use the adapter data
* Convert onViewMedia to use the adapter data
* Convert onMore to use the adapter data
* Convert onReply to use the adapter data
* Convert NotificationViewData to Kotlin
* Re-implement the reblog functionality
- Move reblogging in to the view model
- Update the UI via the adapter's `snapshot()` and `notifyItemChanged()`
methods
* Re-implement the favourite functionality
Same approach as reblog
* Re-implement the bookmark functionality
Same approach as reblog
* Add TODO re StatusActionListener interface
* Add TODO re event handling
* Re-implementing the voting functionality
* Re-implement viewing hidden content
- Hidden media
- Content behind a content warning
* Add a TODO re pinning
* Re-implement "Show more" / "Show less"
* Delete unused updateStatus() function
* Comment out the scroll listener for the moment
* Re-implement applying filters to notifications
Introduce `NotificationsRepository`, to provide access to the notifications
stream.
When changing the filters the flow is as follows:
- User clicks "Apply" in the fragment.
- Fragment calls `viewModel.accept()` with a `UiAction.ApplyFilter` (new
class).
- View model maintains a private flow of incoming UI actions. The new action
is emitted to that flow.
- In view model, `notificationFilter` waits for `.ApplyFilter` actions, and
ensures the filter is saved, then emits it.
- In view model, `pagingDataFlow` waits for new items from
`notificationsFilter` and fetches the notifications from the repository in
response. The repository provides `Notification`, so the model maps them to
`NotificationViewData.Concrete` for display by the adapter.
- In view model the UI state also waits for new items from
`notificationsFilter` and emits a new `UiState` every time the filter is
changed.
When opening the fragment for the first time:
- All of the above machinery, but `notificationFilter` also fetches the filter
from the active account and emits that first. This triggers the first fetch
and the first update of `uiState`.
Also:
- Add TODOs for functionality that is not implemented yet
- Delete a lot of dead code from NotificationsFragment
* Include important preference values in `uiState`
Listen to the flow of eventHub events, filtered to preference changes that
are relevant to the notification view.
When preferences change (or when the view model starts), fetch the current
values, and include them in `uiState`.
Remove preference handling from `NotificationsFragment`, and just use
the values from `uiState`.
Adjust how the `useAbsoluteTime` preference is handled. The previous code
loaded new content (via a diffutil) in to the adapter, which would trigger
a re-binding of the timestamp.
As the adapter content is immutable, the new code simply triggers a
re-binding of the views that are currently visible on screen.
* Update UI in response to different load states
Notifications can be loaded at the top and bottom of the timeline. Add a
new layout to show the progress of these loads, and any errors that can
occur.
Catch network errors in `NotificationsPagingSource` and convert to
`LoadState.Error`.
Add a header/footer to the notifications list to show the load state.
Collect the load state from the adapter, use this to drive the visibility
of different views.
* Save and restore the last read notification ID
Use this when fetching notifications, to centre the list around the
notification that was last read.
* Call notifyItemRangeChanged with the correct parameters
* Don't try and save list position if there are no items in the list
* Show/hide the "Nothing to see" view appropriately
* Update comments
* Handle the case where the notification key no longer exists
* Re-implement support for showMediaPreview and other settings
* Re-implement "hide FAB when scrolling" preference
* Delete dead code
* Delete Notifications Adapater and Placeholder types
* Remove NotificationViewData.Concrete subclass
Now there's no Placeholder, everything is a NotificationViewData.
* Improve how notification pages are loaded if the first notification is missing or filtered
* Re-implement clear notifications, show errors
* s/default/from/
* Add missing headers
* Don't process bookmarking via EventHub
- Initiating a bookmark is triggered by the fragment sending a
StatusUiAction.Bookmark
- View model receives this, makes API call, waits for response, emits either
a success or failure state
- Fragment collects success/failure states, updates the UI accordingly
* Don't process favourites via EventHub
* Don't process reblog via EventHub
* Don't process poll votes with EventHub
This removes EventHub from the fragment
* Respond to follow requests via the view model
* Docs and cleanup
* Typo and editing pass
* Minor edits for clarity
* Remove newline in diagram

* Change "Load more" to load oldest statuses first in home timeline
Previous behaviour loaded missing statuses by using "since_id" and "max_id".
This loads the most recent N statuses, looking backwards from "max_id".
Change to load the oldest statuses first, assuming the user is scrolling
up through the timeline and will want to load statuses in reverse
chronological order.
* Scroll to the bottom of new entries added by "Load more"
- Remember the position of the "Load more" placeholder
- Check the position of inserted entries
- If they match, scroll to the bottom
* Change "Load more" to load oldest statuses first in home timeline
Previous behaviour loaded missing statuses by using "since_id" and "max_id".
This loads the most recent N statuses, looking backwards from "max_id".
Change to load the oldest statuses first, assuming the user is scrolling
up through the timeline and will want to load statuses in reverse
chronological order.
* Scroll to the bottom of new entries added by "Load more"
- Remember the position of the "Load more" placeholder
- Check the position of inserted entries
- If they match, scroll to the bottom
* Ensure the user can't have two simultaneous "Load more" coroutines
Having two simultanous coroutines would break the calculation used to figure
out which item in the list to scroll to after a "Load more" in the timeline.
Do this by:
- Creating a TimelineUiState and associated flow that tracks the "Load more"
state
- Updating this in the (Cached|Network)TimelineViewModel
- Listening for changes to it in TimelineFragment, and notifying the adapter
- The adapter will disable any placeholder views while "Load more" is active
* Revert changes that loaded the oldest statuses instead of the newest
* Be more robust about locating the status to scroll to
Weirdness with the PagingData library meant that positionStart could still be
wrong after "Load more" was clicked.
Instead, remember the position of the "Load more" item and the ID of the
status immediately after it.
When new items are added, search for the remembered status at the position of
the "Load more" item. This is quick, testing at most LOAD_AT_ONCE items in
the adapter.
If the remembered status is not visible on screen then scroll to it.
* Lint
* Add a preference to specify the reading order
Default behaviour (oldest first) is for "load more" to load statuses and
stay at the oldest of the new statuses.
Alternative behaviour (if the user is reading from top to bottom) is to
stay at the newest of the new statuses.
* Move ReadingOrder enum construction logic in to the enum
* Jump to top if swipe/refresh while preferring newest-first order
* Show a circular progress spinner during "Load more" operations
Remove a dedicated view, and use an icon on the button instead.
Adjust the placeholder attributes and styles accordingly.
* Remove the "loadMoreActive" property
Complicates the code and doesn't really achieve the desired effect. If the
user wants to tap multiple "Load more" buttons they can.
* Update comments in TimelineFragment
* Respect the user's reading order preference if it changes
* Add developer tools
This is for functionality that makes it easier for developers to interact
with the app, or get it in to a known-state.
These features are for use by users, so are only visible in debug builds.
* Adjust how content is loaded based on preferred reading order
- Add the readingOrder to TimelineViewModel so derived classes can use it.
- Update the homeTimeline API to support the `minId` parameter and update
calls in NetworkTimelineViewModel
In CachedTimelineViewModel:
- Set the bounds of the load to be the status IDs on either side of the
placeholder ID (update TimelineDao with a new query for this)
- Load statuses using either minId or sinceId depending on the reading order
- Is there was no overlap then insert the new placeholder at the start/end
of the list depending on reading order
* Lint
* Rename unused dialog parameter to _
* Update API arguments in tests
* Simplify ReadingOrder preference handling
* Fix bug with Placeholder and the "expanded" property
If a status is a Placeholder the "expanded" propery is used to indicate
whether or not it is loading.
replaceStatusRange() set this property based on the old value, and the user's
alwaysOpenSpoiler preference setting.
This shouldn't have been used if the status is a Placeholder, as it can lead
to incorrect loading states.
Fix this.
While I'm here, introduce an explicit computed property for whether a
TimelineStatusEntity is a placeholder, and use that for code clarity.
* Set the "Load more" button background to transparent
* Fix typo.
* Inline spec, update comment
* Revert 1480c6aa3a
Turns out the behaviour is not desired.
* Remove unnecessary Log call
* Extract function
* Change default to newest first
* Remove rxjava from API calls used by AccountListFragment
* Remove rxjava from API calls used by AccountViewModel::changeRelationship()
The affected API functions are also called from
- ReportViewModel.kt
- SearchViewModel.kt
- AccountListFragment.kt
- SFragment.java
- TimelineCases.kt
so they have also been updated.
This change requires bridging from Java code to Kotlin `suspend` functions,
by creating wrappers for the `mute` and `block` functions that can be
called from Java and create a coroutine scope.
I've deliberately made this fairly ugly so that it sticks out and can be
removed later.
* Use "Throwable" type and name
* Delete 46.json
Not sure where this came from.
* Remove rxjava from the deleteStatus call path
* Emit log messages with the correct tag
* Add another log tag, and lint
* Use TAG in log messages now it's present
* Lint
* Move viewModelScope.launch in to changeRelationshop()
* Use onSuccess/onFailure pair instead of fold
* Return Deferred when deleting statuses
* Remove rxjava from API calls used by AccountListFragment
* Remove rxjava from API calls used by AccountViewModel::changeRelationship()

- ReportViewModel.kt
