BrowseFragment

The headers fragment is disabled and will never be shown.

The headers fragment is enabled and shown by default.

The headers fragment is enabled and hidden by default.

Create arguments for a browse fragment.

Enables scaling of rows when headers are present. By default enabled to increase density.

Returns the adapter containing the rows for the fragment.

Returns the badge drawable used in the fragment title.

Returns the brand color for the browse fragment. The default is transparent.

Returns the state of the headers column in the browse fragment.

Returns the item clicked listener.

Returns the item Clicked listener.

Returns an item selection listener.

Returns the color used to draw the search affordance.

Returns the SearchOrbView.Colors used to draw the search affordance.

Returns the title for the browse fragment.

Returns true if headers transition on back key support is enabled.

Returns true if the headers transition is currently running.

Returns true if headers are shown.

Called to do initial creation of a fragment. This is called after onAttach(Activity) and before onCreateView(LayoutInflater, ViewGroup, Bundle).

Note that this can be called while the fragment's activity is still in the process of being created. As such, you can not rely on things like the activity's content view hierarchy being initialized at this point. If you want to do work once the activity itself is created, see onActivityCreated(Bundle).

Called to have the fragment instantiate its user interface view. This is optional, and non-graphical fragments can return null (which is the default implementation). This will be called between onCreate(Bundle) and onActivityCreated(Bundle).

If you return a View from here, you will later be called in onDestroyView() when the view is being released.

Called when the fragment is no longer in use. This is called after onStop() and before onDetach().

Called when the Fragment is no longer resumed. This is generally tied to Activity.onPause of the containing Activity's lifecycle.

Called when the fragment is visible to the user and actively running. This is generally tied to Activity.onResume of the containing Activity's lifecycle.

Called to ask the fragment to save its current dynamic state, so it can later be reconstructed in a new instance of its process is restarted. If a new instance of the fragment later needs to be created, the data you place in the Bundle here will be available in the Bundle given to onCreate(Bundle), onCreateView(LayoutInflater, ViewGroup, Bundle), and onActivityCreated(Bundle).

This corresponds to Activity.onSaveInstanceState(Bundle) and most of the discussion there applies here as well. Note however: this method may be called at any time before onDestroy(). There are many situations where a fragment may be mostly torn down (such as when placed on the back stack with no UI showing), but its state will not be saved until its owning activity actually needs to save its state.

Called when the Fragment is visible to the user. This is generally tied to Activity.onStart of the containing Activity's lifecycle.

Called immediately after onCreateView(LayoutInflater, ViewGroup, Bundle) has returned, but before any saved state has been restored in to the view. This gives subclasses a chance to initialize themselves once they know their view hierarchy has been completely created. The fragment's view hierarchy is not however attached to its parent at this point.

Enables entrance transition.

Entrance transition is the standard slide-in transition that shows rows of data in browse screen and details screen.

The method is ignored before LOLLIPOP (API21).

This method must be called in or before onCreate(). Typically entrance transition should be enabled when savedInstance is null so that fragment restored from instanceState does not run an extra entrance transition. When the entrance transition is enabled, the fragment will make headers and content hidden initially. When data of rows are ready, app must call startEntranceTransition() to kick off the transition, otherwise the rows will be invisible forever.

It is similar to android:windowsEnterTransition and can be considered a late-executed android:windowsEnterTransition controlled by app. There are two reasons that app needs it:

Transition object is returned by createEntranceTransition(). Typically the app does not need override the default transition that browse and details provides.

Sets the adapter containing the rows for the fragment.

The items referenced by the adapter must be be derived from Row. These rows will be used by the rows fragment and the headers fragment (if not disabled) to render the browse rows.

Sets the drawable displayed in the browse fragment title.

Sets the brand color for the browse fragment. The brand color is used as the primary color for UI elements in the browse fragment. For example, the background color of the headers fragment uses the brand color.

Set a listener for browse fragment transitions.

Sets the PresenterSelector used to render the row headers.

Sets the state for the headers column in the browse fragment. Must be one of HEADERS_ENABLED, HEADERS_HIDDEN, or HEADERS_DISABLED.

Enable/disable headers transition on back key support. This is enabled by default. The BrowseFragment will add a back stack entry when headers are showing. Running a headers transition when the back key is pressed only works when the headers state is HEADERS_ENABLED or HEADERS_HIDDEN.

NOTE: If an Activity has its own onBackPressed() handling, you must disable this feature. You may use startHeadersTransition(boolean) and BrowseFragment.BrowseTransitionListener in your own back stack handling.

Sets an item clicked listener on the fragment.

OnItemClickedListener will override View.OnClickListener that an item presenter may set during onCreateViewHolder(ViewGroup). So in general, you should choose to use an OnItemClickedListener or a View.OnClickListener on your item views, but not both.

Sets an item selection listener. This listener will be called when an item or row is selected by a user.

Sets an item clicked listener on the fragment. OnItemViewClickedListener will override View.OnClickListener that item presenter sets during onCreateViewHolder(ViewGroup). So in general, developer should choose one of the listeners but not both.

Sets an item selection listener.

Sets a click listener for the search affordance.

The presence of a listener will change the visibility of the search affordance in the fragment title. When set to non-null, the title will contain an element that a user may click to begin a search.

The listener's onClick method will be invoked when the user clicks on the search element.

Sets the color used to draw the search affordance. A default brighter color will be set by the framework.

Sets the SearchOrbView.Colors used to draw the search affordance.

Sets the selected row position.

Sets the selected row position with smooth animation.

Sets a title for the browse fragment.

When fragment finishes loading data, it should call startEntranceTransition() to execute the entrance transition. startEntranceTransition() will start transition only if both two conditions are satisfied:

If startEntranceTransition() is called before onViewCreated(), it will be pending and executed when view is created.

Start a headers transition.

This method will begin a transition to either show or hide the headers, depending on the value of withHeaders. If headers are disabled for this browse fragment, this method will throw an exception.

Create entrance transition. Subclass can override to load transition from resource or construct manually. Typically app does not need to override the default transition that browse and details provides.

Callback when entrance transition is ended.

Callback when entrance transition is started.

Run entrance transition. Subclass may use TransitionManager to perform go(Scene) or beginDelayedTransition(). App should not override the default implementation of browse and details fragment.
