				↳	androidx.wear.widget.SwipeDismissFrameLayout

A layout enabling left-to-right swipe-to-dismiss, intended for use within an activity.

At least one listener must be added to act on a dismissal action. A listener will typically remove a containing view or fragment from the current activity.

To suppress a swipe-dismiss gesture, at least one contained view must be scrollable, indicating that it would like to consume any horizontal touch gestures in that direction. In this case this view will only allow swipe-to-dismiss on the very edge of the left-hand-side of the screen. If you wish to entirely disable the swipe-to-dismiss gesture, setSwipeable(boolean) can be used for more direct control over the feature.

Public constructors

<init>

SwipeDismissFrameLayout(context: Context!)

Simple constructor to use when creating a view from code.

Parameters
`context`	Context!: The `Context` the view is running in, through which it can access the current theme, resources, etc.

<init>

SwipeDismissFrameLayout(
    context: Context!, 
    attrs: AttributeSet!)

Constructor that is called when inflating a view from XML. This is called when a view is being constructed from an XML file, supplying attributes that were specified in the XML file. This version uses a default style of 0, so the only attribute values applied are those in the Context's Theme and the given AttributeSet.

The method onFinishInflate() will be called after all children have been added.

Parameters
`context`	Context!: The `Context` the view is running in, through which it can access the current theme, resources, etc.
`attrs`	AttributeSet!: The attributes of the XML tag that is inflating the view.

<init>

SwipeDismissFrameLayout(
    context: Context!, 
    attrs: AttributeSet!, 
    defStyle: Int)

Perform inflation from XML and apply a class-specific base style from a theme attribute. This constructor allows subclasses to use their own base style when they are inflating.

Parameters
`context`	Context!: The `Context` the view is running in, through which it can access the current theme, resources, etc.
`attrs`	AttributeSet!: The attributes of the XML tag that is inflating the view.
`defStyle`	Int: An attribute in the current theme that contains a reference to a style resource that supplies default values for the view. Can be 0 to not look for defaults.

<init>

SwipeDismissFrameLayout(
    context: Context!, 
    attrs: AttributeSet!, 
    defStyle: Int, 
    defStyleRes: Int)

Perform inflation from XML and apply a class-specific base style from a theme attribute. This constructor allows subclasses to use their own base style when they are inflating.

Parameters
`context`	Context!: The `Context` the view is running in, through which it can access the current theme, resources, etc.
`attrs`	AttributeSet!: The attributes of the XML tag that is inflating the view.
`defStyle`	Int: An attribute in the current theme that contains a reference to a style resource that supplies default values for the view. Can be 0 to not look for defaults.
`defStyleRes`	Int: It allows a style resource to be specified when creating the view.
