Refactored AbstractDetailsFragment This introduces the MVC model to details fragments. It moves as much view and control code out of the concrete fragments into the abstract classes. * Added UML class and sequence diagrams under doc/diagrams to clarify the new setup * Introduces new abstract classes * AbstractFragment class to hold the DataHolder * AbstractInfoFragment class to display media information * AbstractAddtionalInfoFragment class to allow *InfoFragments to add additional UI elements and propagate refresh requests. See for an example TVShowInfoFragment which adds TVShowProgressFragment to display next episodes and season progression. * Introduces new RefreshItem class to encapsulate all refresh functionality from AbstractDetailsFragment * Introduces new SharedElementTransition utility class to encapsulate all shared element transition code * Introduces new CastFragment class to encapsulate all code for displaying casts reducing code duplication * Introduces DataHolder class to replace passing the ViewHolder from the *ListFragment to the *DetailsFragment or *InfoFragment * Refactored AbstractDetailsFragment into two classes: o AbstractDetailsFragment: for fragments requiring a tab bar o AbstractInfoFragment: for fragments showing media information We used to use <NAME>DetailsFragments for both fragments that show generic info about some media item and fragments that hold all details for some media item. For example, artist details showed artist info and used tabs to show artist albums and songs as well. Now Details fragments are used to show all details, Info fragments only show media item information like description, title, rating, etc. * Moved swiperefreshlayout code from AbstractCursorListFragment to AbstractListFragment

Defines mandatory methods for fragments that can be added to
information fragments

abstract class AbstractInfoFragment {
Defines a common UI for information fragments. Concrete implementations
of this class should ideally only provide the data, while the
AbstractInfoFragment contains the logic to present the UI and react to
user input.
-- Implements --
+ boolean isSharedElementVisible()
-- Generic --
Allows concrete fragment to get certain data or update the UI
--
# void refreshAdditionInfoFragment()
# HostManager getHostManager()
# HostInfo getHostInfo()
# void updateView(DataHolder dataHolder)
# RefreshItem getRefreshItem()
# void setExpandDescription(boolean expandDescription)
-- Media action bar --
Adding a listener in a concrete fragment will add the corresponding
button to the UI
--
# void setOnDownloadListener(final View.OnClickListener listener)
# void setOnAddToPlaylistListener(View.OnClickListener listener)
# void setOnGoToImdbListener(View.OnClickListener listener)
# void setOnSeenListener(final View.OnClickListener listener)
# void setOnPinClickedListener(final View.OnClickListener listener)
# void setDownloadButtonState(boolean state)
# void setSeenButtonState(boolean state)
# void setPinButtonState(boolean state)
-- Abstract methods --
Every concrete fragment is able to add additional info using an
AbstractAdditionalInfoFragment. This will be placed below the generic info.
Every concrete fragment should implement a refresh functionality.
The method setupMediaActionBar() will be called when the media action bar buttons
are available. This is where the concrete fragment should call the setOn*Listeners
to connect listeners to specific media action buttons.
The method setupFAB(ImageButton FAB) will be called to allow adding a listener.
It should return true to enable the FAB, false to disabled it.

# {abstract} AbstractAdditionalInfoFragment getAdditionalInfoFragment()
# {abstract} RefreshItem createRefreshItem()
# {abstract} boolean setupMediaActionBar()
# {abstract} boolean setupFAB(ImageButton FAB)
}
abstract class AbstractTabsFragment {
Defines a common UI for fragments that want to use a viewpager and a scrollable tab bar.
-- Implements --
+ boolean isSharedElementVisible()
--
# {abstract} TabsAdapter createTabsAdapter(AbstractInfoFragment.DataHolder dataHolder)
}
class ConcreteTabsFragment {
The returned TabsAdapter should hold all required tabs
# TabsAdapter createTabsAdapter(AbstractInfoFragment.DataHolder dataHolder)
}
class ConcreteInfoFragment {
Should be able to provide the required information by updating the DataHolder.
Use getDataHolder() to get the current DataHolder and update it. Use updateView(DataHolder)
to force an update of the UI with the updated DataHolder.
