Public methods

build

public RoutePreviewNavigationTemplate build ()

Constructs the template defined by this builder.

Requirements

Either a header Action or title must be set on the template.

Returns
`RoutePreviewNavigationTemplate`

Throws
`IllegalStateException`	if the template is in a loading state but the list is set, or vice-versa.
`IllegalStateException`	if the template is not loading and the navigation action is not set.
`IllegalStateException`	if the template does not have either a title or header `Action` set.

setActionStrip

public RoutePreviewNavigationTemplate.Builder setActionStrip (ActionStrip actionStrip)

Sets the ActionStrip for this template, or null to not show an ActionStrip.

Requirements

This template allows up to 2 Actions in its ActionStrip. Of the 2 allowed Actions, one of them can contain a title as set via Action.Builder.setTitle(CharSequence). Otherwise, only Actions with icons are allowed.

Parameters
`actionStrip`	`ActionStrip`

Returns
`RoutePreviewNavigationTemplate.Builder`

Throws
`IllegalArgumentException`	if `actionStrip` does not meet the template's requirements.

setHeaderAction

public RoutePreviewNavigationTemplate.Builder setHeaderAction (Action headerAction)

Sets the Action that will be displayed in the header of the template, or null to now display an action.

Requirements

This template only supports either either one of Action.APP_ICON and Action.BACK as a header Action.

Parameters
`headerAction`	`Action`

Returns
`RoutePreviewNavigationTemplate.Builder`

Throws
`IllegalArgumentException`	if `headerAction` does not meet the template's requirements.

setIsLoading

public RoutePreviewNavigationTemplate.Builder setIsLoading (boolean isLoading)

Sets whether the template is in a loading state.

If set to true, the UI will show a loading indicator where the list content would be otherwise. The caller is expected to call Screen.invalidate() and send the new template content to the host once the data is ready. If set to false, the UI shows the ItemList contents added via setItemList(ItemList).

Parameters
`isLoading`	`boolean`

Returns
`RoutePreviewNavigationTemplate.Builder`

setItemList

public RoutePreviewNavigationTemplate.Builder setItemList (ItemList itemList)

Sets an ItemList to show route options in a list view along with the map.

Requirements

This template allows up to 3 Rows in the ItemList. The host will ignore any items over that limit. The list must have an OnClickListener set. Each Row can add up to 2 lines of texts via Row.Builder.addText(CharSequence) and cannot contain a Toggle.

Images of type Row.IMAGE_TYPE_LARGE are not allowed in this template.

All rows must have either a DistanceSpan or a DurationSpan attached to either its title or texts, to indicate an estimate trip distance or duration for the route it represents. Where in the title or text these spans are attached to is up to the app.

Parameters
`itemList`	`ItemList`

Returns
`RoutePreviewNavigationTemplate.Builder`

Throws
`IllegalArgumentException`	if `itemList` does not meet the template's requirements.

setNavigateAction

public RoutePreviewNavigationTemplate.Builder setNavigateAction (Action navigateAction)

Sets the Action to allow users to request navigation using the currently selected route.

This should not be null if the template is not in a loading state (see #setIsLoading}), and the Action's title must be set.

Parameters
`navigateAction`	`Action`

Returns
`RoutePreviewNavigationTemplate.Builder`

Throws
`NullPointerException`	if `navigateAction` is `null`.
`IllegalArgumentException`	if `navigateAction`'s title is `null` or empty.

setTitle

public RoutePreviewNavigationTemplate.Builder setTitle (CharSequence title)

Sets the CharSequence to show as title, or null to not show a title.

Parameters
`title`	`CharSequence`

Returns
`RoutePreviewNavigationTemplate.Builder`
