Constants
LAYOUT_MODE_CLIP_BOUNDS
static val LAYOUT_MODE_CLIP_BOUNDS: Int
This constant is a layoutMode
. Clip bounds are the raw values of left
, top
, right
and bottom
.
Value: 0
LAYOUT_MODE_OPTICAL_BOUNDS
static val LAYOUT_MODE_OPTICAL_BOUNDS: Int
This constant is a layoutMode
. Optical bounds describe where a widget appears to be. They sit inside the clip bounds which need to cover a larger area to allow other effects, such as shadows and glows, to be drawn.
Value: 1
Public methods
getLayoutMode
static fun getLayoutMode(@NonNull group: ViewGroup): Int
Returns the basis of alignment during layout operations on this ViewGroup: either LAYOUT_MODE_CLIP_BOUNDS
or LAYOUT_MODE_OPTICAL_BOUNDS
.
If no layoutMode was explicitly set, either programmatically or in an XML resource, the method returns the layoutMode of the view's parent ViewGroup if such a parent exists, otherwise the method returns a default value of LAYOUT_MODE_CLIP_BOUNDS
.

getNestedScrollAxes
static fun getNestedScrollAxes(@NonNull group: ViewGroup): Int

A ViewGroup returning something other than ViewCompat#SCROLL_AXIS_NONE
is currently acting as a nested scrolling parent for one or more descendant views in the hierarchy.
Return | |

Int |
Flags indicating the current axes of nested scrolling |
isTransitionGroup
static fun isTransitionGroup(@NonNull group: ViewGroup): Boolean
Returns true if this ViewGroup should be considered as a single entity for removal when executing an Activity transition. If this is false, child elements will move individually during the transition.
onRequestSendAccessibilityEvent
static funonRequestSendAccessibilityEvent(
group: ViewGroup!,
child: View!,
event: AccessibilityEvent!
): Boolean
Deprecated: Use ViewGroup#onRequestSendAccessibilityEvent(View, AccessibilityEvent)
directly.
Called when a child has requested sending an AccessibilityEvent
and gives an opportunity to its parent to augment the event.
