* Add serialization of the meta-data and focus objects
These objects are added in some attachments. This commit adds data
classes which are able to serialize these (partially) in preparation
for the ability to honour the focal point information in image
previews.
* Implement correctly honouring the focal point meta-data in previews
This commit adds code which ensures that the image previews of media
attachments to toots are correctly cropped to always show the focal
point of the image (if it is specified). It should not in any way
influence how previews of media without a focal point are shown.
To achieve the correct crop on the image a few components were
needed:
First of all we needed a way to influence how the image is cropped
into the ImageView. It turns out that the preferred way to do this is
by setting the ScaleType to MATRIX and adjusting the matrix of the
image as needed. This matrix allows us to scale and transform the
image in the way we need to make sure that the focal point is visible
within the view. For this purpose we have the FocalPointEnforcer which
can calculate and set the appropriate matrix on an ImageView as soon
as the image is loaded.
However a second problem is that we need to make sure that this matrix
is updated whenever the size of the ImageView changes. The size might
change for example because the orientation of the device changed from
portrait to landscape or vice versas, or for a number of other reasons
such as the screen being split vertically or something like that.
To be able to hook onto this event we need to create a new extended
version of the ImageView class, which we call
MediaPreviewImageView. This class behaves exactly the same as a normal
ImageView, however if the focalPointEnforcer of this view is set, then
it will call this enforcer to update the image matrix any time the
size is changed.
So this commit changes all media previews in the item_status.xml and
item_status_detailled.xml layout files to the new
MediaPreviewImageView class. Additionally in the code for loading the
images into the previews a new case is added which tests if there is a
focus attribute in the meta-data. If so it makes sure to create and
set the FocalPointEnforcer.
* Fix typos in documentation comment
"to" -> "too"
* Use static imports to remove clutter in FocalPointEnforcerTest
Instead of duplication Assert. in front of every assertEquals, simply
statically import it.
* Move the MetaData and Focus classes into the Attachment class
Since they are very strongly linked to the attachment class and are
themselves very small.
* Refactor the focal point handling code
- All the code modifying the actual members of the
MediaPreviewImageView is now in this class itself. This class still
uses the FocalPointUtil to calculate the new Matrix, but it now
handles setting this new Matrix itself.
- The FocalPointEnforcer has been renamed to the FocalPointUtil to
reflect that it only calculates the correct matrix, but doesn't set
anything on the MediaPreviewImageView.
- The Matrix used to control the cropping of the
MediaPreviewImageViews is now only allocated a single time per view
instead of each time the view is resized. This is done by caching
the Matrix and passing it to the FocalPointUtil to update on each
resize.
* Only reallocate focalMatrix if it is not yet initialized
This helps prevent unnecessary allocations in the case where
setFocalPoint is called multiple times.
* Change checking of availability of objects to use != null
As pointed out, the 'is' keyword is meant for checking types, not for
checking non-nullness.
* Make updateFocalPointMatrix() return nothing
This makes it clearer that it actually mutates the matrix it is
given.
* Fix bug with transitions crashing the PhotoView
Due to the android transitions for some reason copying the scaletype
from the MediaPreviewImageView to the PhotoView during the transition,
the PhotoView would crash on pictures with a focal point, since
PhotoView doesn't support ScaleType.MATRIX.
This is solved by the workaround of overriding both the getScaleType
and setScaleType methods to ensure that we use the MATRIX type in the
preview and the center_crop type in the PhotoView.
Additionally this commit also makes sure to remove the focal point
when the MediaPreviewImageView is recycled.
* Fix bug in overriden getScaleType
Instead of simply returning the scaleType we need to return the
super.getScaleType() method, to avoid crashing.
* Merge changes from master
Mainly the migration to androidx.
* Update zh-rTW translation
* Add missing translation
* Copy zh-rTW strings to HK and MO for now, per @connyduck 's request
https://github.com/tuskyapp/Tusky/pull/930#issuecomment-450240996
Note that this should not be the final solution, HK and MO should be
able to understand the TW variant, but they're still different.
