GuidedStepSupportFragment

Added in 1.1.0

Kotlin |Java

public class GuidedStepSupportFragment extends Fragment

java.lang.Object
↳	androidx.fragment.app.Fragment
	↳	androidx.leanback.app.GuidedStepSupportFragment

A GuidedStepSupportFragment is used to guide the user through a decision or series of decisions. It is composed of a guidance view on the left and a view on the right containing a list of possible actions.

Basic Usage

Clients of GuidedStepSupportFragment must create a custom subclass to attach to their Activities. This custom subclass provides the information necessary to construct the user interface and respond to user actions. At a minimum, subclasses should override:

onCreateGuidance, to provide instructions to the user
onCreateActions, to provide a set of GuidedActions the user can take
onGuidedActionClicked, to respond to those actions

Clients use following helper functions to add GuidedStepSupportFragment to Activity or FragmentManager:

addAsRoot, to be called during Activity onCreate, adds GuidedStepSupportFragment as the first Fragment in activity.
add or add, to add GuidedStepSupportFragment on top of existing Fragments or replacing existing GuidedStepSupportFragment when moving forward to next step.
finishGuidedStepSupportFragments can either finish the activity or pop all GuidedStepSupportFragment from stack.
If app chooses not to use the helper function, it is the app's responsibility to call setUiStyle to select fragment transition and remember the stack entry where it need pops to.

Theming and Stylists

GuidedStepSupportFragment delegates its visual styling to classes called stylists. The is responsible for the left guidance view, while the is responsible for the right actions view. The stylists use theme attributes to derive values associated with the presentation, such as colors, animations, etc. Most simple visual aspects of GuidanceStylist and GuidedActionsStylist can be customized via theming; see their documentation for more information.

GuidedStepSupportFragments must have access to an appropriate theme in order for the stylists to function properly. Specifically, the fragment must receive Theme_Leanback_GuidedStep, or a theme whose parent is is set to that theme. Themes can be provided in one of three ways:

The simplest way is to set the theme for the host Activity to the GuidedStep theme or a theme that derives from it.
If the Activity already has a theme and setting its parent theme is inconvenient, the existing Activity theme can have an entry added for the attribute LeanbackGuidedStepTheme_guidedStepTheme. If present, this theme will be used by GuidedStepSupportFragment as an overlay to the Activity's theme.
Finally, custom subclasses of GuidedStepSupportFragment may provide a theme through the onProvideTheme method. This can be useful if a subclass is used across multiple Activities.

If the theme is provided in multiple ways, the onProvideTheme override has priority, followed by the Activity's theme. (Themes whose parent theme is already set to the guided step theme do not need to set the guidedStepTheme attribute; if set, it will be ignored.)

If themes do not provide enough customizability, the stylists themselves may be subclassed and provided to the GuidedStepSupportFragment through the onCreateGuidanceStylist and onCreateActionsStylist methods. The stylists have simple hooks so that subclasses may override layout files; subclasses may also have more complex logic to determine styling.

Guided sequences

GuidedStepSupportFragments can be grouped together to provide a guided sequence. GuidedStepSupportFragments grouped as a sequence use custom animations provided by GuidanceStylist and GuidedActionsStylist (or subclasses) during transitions between steps. Clients should use add to place subsequent GuidedFragments onto the fragment stack so that custom animations are properly configured. (Custom animations are triggered automatically when the fragment stack is subsequently popped by any normal mechanism.)

Note: Currently GuidedStepSupportFragments grouped in this way must all be defined programmatically, rather than in XML. This restriction may be removed in the future.guidedStepThemeguidedStepBackgroundguidedActionContentWidthWeightguidedActionContentWidthWeightTwoPanelsguidedActionsBackgroundguidedActionsBackgroundDarkguidedActionsElevation

EXTRA_UI_STYLE

Added in 1.1.0

public static final String EXTRA_UI_STYLE = "uiStyle"

Fragment argument name for UI style. The argument value is persisted in fragment state and used to select fragment transition. The value is initially UI_STYLE_ENTRANCE and might be changed in one of the three helper functions:

addAsRoot sets to UI_STYLE_ACTIVITY_ROOT
add or add sets it to UI_STYLE_REPLACE if there is already a GuidedStepSupportFragment on stack.
finishGuidedStepSupportFragments changes current GuidedStepSupportFragment to UI_STYLE_ENTRANCE for the non activity case. This is a special case that changes the transition settings after fragment has been created, in order to force current GuidedStepSupportFragment run a return transition of UI_STYLE_ENTRANCE

Argument value can be either:

UI_STYLE_ACTIVITY_ROOT

Added in 1.1.0

public static final int UI_STYLE_ACTIVITY_ROOT = 2

One possible value of argument EXTRA_UI_STYLE. This is the case that we show first GuidedStepSupportFragment in a separate activity. The default behavior of this style:

Enter transition is assigned null (will rely on activity transition), exit transition is same as UI_STYLE_ENTRANCE. Note: Changing exit transition by UI style is not working because fragment transition asks for exit transition before UI style is restored in Fragment.onCreate().

UI_STYLE_DEFAULT

Added in 1.1.0

Deprecated in 1.1.0

public static final int UI_STYLE_DEFAULT = 0

UI_STYLE_ENTRANCE

Added in 1.1.0

public static final int UI_STYLE_ENTRANCE = 1

Default value for argument EXTRA_UI_STYLE. The default value is assigned in GuidedStepSupportFragment constructor. This is the case that we show GuidedStepSupportFragment on top of other content. The default behavior of this style:

Enter transition slides in from two sides, exit transition slide out to START(left). Background will be faded in. Note: Changing exit transition by UI style is not working because fragment transition asks for exit transition before UI style is restored in Fragment .onCreate().

When popping multiple GuidedStepSupportFragment, finishGuidedStepSupportFragments also changes the top GuidedStepSupportFragment to UI_STYLE_ENTRANCE in order to run the return transition (reverse of enter transition) of UI_STYLE_ENTRANCE.

UI_STYLE_REPLACE

Added in 1.1.0

public static final int UI_STYLE_REPLACE = 0

This is the case that we use GuidedStepSupportFragment to replace another existing GuidedStepSupportFragment when moving forward to next step. Default behavior of this style is:

Enter transition slides in from END(right), exit transition same as UI_STYLE_ENTRANCE.

)

Adds the specified GuidedStepSupportFragment to the fragment stack, replacing any existing GuidedStepSupportFragments in the stack, and configuring the fragment-to-fragment custom transitions. A backstack entry is added, so the fragment will be dismissed when BACK key is pressed.

If current fragment on stack is GuidedStepSupportFragment: assign UI_STYLE_REPLACE
If current fragment on stack is not GuidedStepSupportFragment: assign UI_STYLE_ENTRANCE

Note: currently fragments added using this method must be created programmatically rather than via XML.

Parameters
`@NonNull FragmentManager fragmentManager`	The FragmentManager to be used in the transaction.
`@NonNull GuidedStepSupportFragment fragment`	The GuidedStepSupportFragment to be inserted into the fragment stack.

Returns
`int`	The ID returned by the call FragmentTransaction.commit.

add

public static int add(
    @NonNull FragmentManager fragmentManager,
    @NonNull GuidedStepSupportFragment fragment,
    int id
)

If current fragment on stack is GuidedStepSupportFragment: assign UI_STYLE_REPLACE and onAddSharedElementTransition will be called to perform shared element transition between GuidedStepSupportFragments.
If current fragment on stack is not GuidedStepSupportFragment: assign UI_STYLE_ENTRANCE

Note: currently fragments added using this method must be created programmatically rather than via XML.

Parameters
`@NonNull FragmentManager fragmentManager`	The FragmentManager to be used in the transaction.
`@NonNull GuidedStepSupportFragment fragment`	The GuidedStepSupportFragment to be inserted into the fragment stack.

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, add a on the activity's Lifecycle, removing it when it receives the Lifecycle.State#CREATED callback.

Any restored child fragments will be created before the base Fragment.onCreate method returns.

Added in 1.1.0

public void onCreateActions(
    @NonNull List<GuidedAction> actions,
    @Nullable Bundle savedInstanceState

`@NonNull GuidanceStylist`	The GuidanceStylist used in this fragment.

onCreateView

public @Nullable View onCreateView(
    @NonNull LayoutInflater inflater,
    @Nullable ViewGroup container,
    @Nullable Bundle savedInstanceState
)

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

A default View can be returned by calling #Fragment(int) in your constructor. Otherwise, this method returns null.

It is recommended to only inflate the layout in this method and move logic that operates on the returned View to #onViewCreated(View, Bundle).

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

onDestroyView

public void onDestroyView()

Called when the view previously created by #onCreateView has been detached from the fragment. The next time the fragment needs to be displayed, a new view will be created. This is called after #onStop() and before #onDestroy(). It is called regardless of whether #onCreateView returned a non-null view. Internally it is called after the view's state has been saved but before it has been removed from its parent.

Added in 1.1.0

public void onGuidedActionClicked(@NonNull GuidedAction action)

Callback invoked when an action is taken by the user. Subclasses should override in order to act on the user's decisions.

Parameters
`@NonNull GuidedAction action`	The chosen action.

Added in 1.1.0

public void onGuidedActionEditCanceled(@NonNull GuidedAction action)

Callback invoked when an action has been canceled editing, for example when user closes IME window by BACK key. Default implementation calls deprecated method onGuidedActionEdited.

Parameters
`@NonNull GuidedAction action`	The action which has been canceled editing.

Added in 1.1.0

Deprecated in 1.1.0

public void onGuidedActionEdited(GuidedAction action)

Callback invoked when an action's title or description has been edited, this happens either when user clicks confirm button in IME or user closes IME window by BACK key.

Added in 1.1.0

public long onGuidedActionEditedAndProceed(@NonNull GuidedAction action)

Callback invoked when an action has been edited, for example when user clicks confirm button in IME window. Default implementation calls deprecated method onGuidedActionEdited and returns ACTION_ID_NEXT.

Parameters
`@NonNull GuidedAction action`	The action that has been edited.

Returns
`long`	ID of the action will be focused or `ACTION_ID_NEXT`, `ACTION_ID_CURRENT`.

Added in 1.1.0

public void onGuidedActionFocused(@NonNull GuidedAction action)

Callback invoked when an action is focused (made to be the current selection) by the user.

onProvideTheme

Added in 1.1.0

public int onProvideTheme()

Returns the theme used for styling the fragment. The default returns -1, indicating that the host Activity's theme should be used.

Returns
`int`	The theme resource ID of the theme to use in this fragment, or -1 to use the host Activity's theme.

onResume

public void onResume()

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.

onSaveInstanceState

public void onSaveInstanceState(@NonNull Bundle outState)

Called to ask the fragment to save its current dynamic state, so it can later be reconstructed in a new instance if 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 #onViewCreated(View, Bundle).

This corresponds to Activity#onSaveInstanceState(Bundle) 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.

Added in 1.1.0

public boolean onSubGuidedActionClicked(@NonNull GuidedAction action)

Callback invoked when an action in sub actions is taken by the user. Subclasses should override in order to act on the user's decisions. Default return value is true to close the sub actions list.

Parameters
`@NonNull GuidedAction action`	The chosen action.

Returns
`boolean`	true to collapse the sub actions list, false to keep it expanded.

Added in 1.1.0

public void openInEditMode(@Nullable GuidedAction action)

public void setActions(@NonNull List<GuidedAction> actions)

Sets the list of GuidedActions that the user may take in this fragment. Uses DiffCallback set by setActionsDiffCallback.

Parameters
`@NonNull List<GuidedAction> actions`	The list of GuidedActions for this fragment.

Added in 1.1.0

public void setActionsDiffCallback(
    @Nullable DiffCallback<GuidedAction> diffCallback
)

Sets the RecyclerView DiffCallback used when setActions is called. By default GuidedStepSupportFragment uses androidx.leanback.widget.GuidedActionDiffCallback. Sets it to null if app wants to refresh the whole list.

Parameters
`@Nullable DiffCallback<GuidedAction> diffCallback`	DiffCallback used in `setActions`.

Added in 1.1.0

public void setButtonActions(@NonNull List<GuidedAction> actions)

Sets the list of button GuidedActions that the user may take in this fragment.

Parameters
`@NonNull List<GuidedAction> actions`	The list of button GuidedActions for this fragment.

setSelectedActionPosition

Added in 1.1.0

public void setSelectedActionPosition(int position)

Scrolls the action list to the position indicated, selecting that action's view.

Parameters
`int position`	The integer position of the action of interest.

setSelectedButtonActionPosition

Added in 1.1.0

public void setSelectedButtonActionPosition(int position)

Scrolls the action list to the position indicated, selecting that button action's view.

Parameters
`int position`	The integer position of the button action of interest.

setUiStyle

Added in 1.1.0

public void setUiStyle(int style)

Set UI style to fragment arguments. Default value is UI_STYLE_ENTRANCE when fragment is first initialized. UI style is used to choose different fragment transition animations and determine if this is the first GuidedStepSupportFragment on backstack. In most cases app does not directly call this method, app calls helper function add. However if the app creates Fragment transaction and controls backstack by itself, it would need call setUiStyle() to select the fragment transition to use.

Parameters
`int style`	`UI_STYLE_ACTIVITY_ROOTUI_STYLE_REPLACE` or `UI_STYLE_ENTRANCE`.

Protected methods

onAddSharedElementTransition

Added in 1.1.0

protected void onAddSharedElementTransition(
    @NonNull FragmentTransaction ft,
    @NonNull GuidedStepSupportFragment disappearing
)

Called when this fragment is added to FragmentTransaction with UI_STYLE_REPLACE (aka when the GuidedStepSupportFragment replacing an existing GuidedStepSupportFragment). Default implementation establishes connections between action background views to morph action background bounds change from disappearing GuidedStepSupportFragment into this GuidedStepSupportFragment. The default implementation heavily relies on GuidedActionsStylist's layout, app may override this method when modifying the default layout of GuidedActionsStylist.

Parameters
`@NonNull FragmentTransaction ft`	The FragmentTransaction to add shared element.
`@NonNull GuidedStepSupportFragment disappearing`	The disappearing fragment.

See also
`GuidedActionsStylist`
`onProvideFragmentTransitions`

onProvideFragmentTransitions

Added in 1.1.0

protected void onProvideFragmentTransitions()

Called by Constructor to provide fragment transitions. The default implementation assigns transitions based on getUiStyle:

UI_STYLE_REPLACE Slide from/to end(right) for enter transition, slide from/to start(left) for exit transition, shared element enter transition is set to ChangeBounds.
UI_STYLE_ENTRANCE Enter transition is set to slide from both sides, exit transition is same as UI_STYLE_REPLACE, no shared element enter transition.
UI_STYLE_ACTIVITY_ROOT Enter transition is set to null and app should rely on activity transition, exit transition is same as UI_STYLE_REPLACE, no shared element enter transition.

The default implementation heavily relies on GuidedActionsStylist and GuidanceStylist layout, app may override this method when modifying the default layout of GuidedActionsStylist or GuidanceStylist.

TIP: because the fragment view is removed during fragment transition, in general app cannot use two Visibility transition together. Workaround is to create your own Visibility transition that controls multiple animators (e.g. slide and fade animation in one Transition class).
