Database updates can be surprisingly slow. This lead to slow updates of
the user interface which in turn made working with K-9 Mail not as fun
as it should be. This commit hopefully changes that.
This happened for example in a starred-message-only view when
un-starting the last message. This led to isFirst() and isLast()
causing a NullPointerException when trying to update the
previous / next buttons.
The ContextThemeWrapper added in a74d57cb71
used getActivity().getApplicationContext() to get the base context.
This is wrong, because an Application context won't work for starting
activities from the WebView.
Instead, use the context that is given to us in the constructor as base
context. This is the one that would also be used if no ContextThemeWrapper
was present at all.
- The attachments view still had the wrong background color in case
of different global and message themes.
- The attachments view used the activity LayoutInflater, but it needs
to use the one of the fragment.
- The background drawable for the attachments used transparency, and
thus was completely invisible in the black theme. Fix it by adding
another one for the black theme.
When MessageListFragment is on the back stack and the device is rotated
the instance state will be restored but no new view will be created. If
the device is rotated again onSaveInstanceState() is called and we have
to take care not to assume that the views have been created.
- Since the split-view change, MessageView is only a fragment, so we
can't call setTheme() anymore so easily.
Instead, use a ContextThemeWrapper and use that to inflate the
layout. This way the message header and attachment view
are styled correctly.
- The HTC WebView fix in SingleMessageView was returning the wrong
background color, when message view theme and global theme differ,
because it always used the global theme to retrieve it.
Fix: Specifically put the light/dark values in the themes.xml,
and get them using getContext().getTheme().resolveAttribute().
getContext() will use the ContextThemeWrapper from above, so
even if the global and message view themes differ, it aleays
returns the correct one.
The getThemeBackgroundColor() method added to the K9ActivityMagic
interface in 309eeb72ac is now not
needed anymore, and was removed.
The previous code worked fine on Android 4.2. But the lifecycle on older
Android versions (tested with 2.2) seems to be slightly different. This
should fix the problem.
* zjw/progress_indicators:
Provide a progress indicator while loading remote search results.
Remove the progress bar from the message list footer.
Provide progress indicator for searches.
Conflicts:
src/com/fsck/k9/activity/MessageList.java
Searches can be slow, so users need an indicator. The indicator is
also used when opening a message list or when refreshing it, or when
loading more messages.
This also removes some unused code.
- disable pull-to-refresh while showing the "Loading..." view
- move initialization code from onResume() to initializePullToRefresh()
and call it from onCreateView()
With the introduction of the action bar there is no longer a separate
button bar for refile actions. So it's no longer necessary to hide the
buttons to save screen space.
This changes the interface to MessagingController and the way flags are
updated in the database. Now messages aren't changed one by one but in
batches of 500. This should give better performance, but breaks the
unread and flagged count. I'm not very sad about this, because now we
can move towards only displaying the number of unread/flagged messages
in the local database.
Disabled "sort by sender" for now because the database can't sort by
contact names from the contacts database. We probably have to
special-case that and do in-memory sorting.
