ViewGroupCompat

public static final int LAYOUT_MODE_CLIP_BOUNDS = 0

This constant is a layoutMode. Clip bounds are the raw values of left, top, right and bottom.

public static final int LAYOUT_MODE_OPTICAL_BOUNDS = 1

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.

@ReplaceWith(expression = "group.getLayoutMode()")
public static int getLayoutMode(@NonNull ViewGroup group)

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.

public static int getNestedScrollAxes(@NonNull ViewGroup group)

Return the current axes of nested scrolling for this ViewGroup.

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

public static void installCompatInsetsDispatch(@NonNull View root)

Installs a custom View.OnApplyWindowInsetsListener which dispatches WindowInsets to the given root and its descendants in a way compatible with Android R+ that consuming or modifying insets will only affect the descendants.

Note: When using this method, ensure that ViewCompat.setOnApplyWindowInsetsListener() is used instead of the platform call.

public static boolean isTransitionGroup(@NonNull ViewGroup group)

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.

@ReplaceWith(expression = "group.onRequestSendAccessibilityEvent(child, event)")
public static boolean onRequestSendAccessibilityEvent(
    ViewGroup group,
    View child,
    AccessibilityEvent event
)

Called when a child has requested sending an AccessibilityEvent and gives an opportunity to its parent to augment the event.

If an AccessibilityDelegateCompat has been specified via calling setAccessibilityDelegate its onRequestSendAccessibilityEvent is responsible for handling this call.

@ReplaceWith(expression = "group.setLayoutMode(mode)")
public static void setLayoutMode(@NonNull ViewGroup group, int mode)

Sets the basis of alignment during the layout of this ViewGroup. Valid values are either LAYOUT_MODE_CLIP_BOUNDS or LAYOUT_MODE_OPTICAL_BOUNDS.

@ReplaceWith(expression = "group.setMotionEventSplittingEnabled(split)")
public static void setMotionEventSplittingEnabled(ViewGroup group, boolean split)

Enable or disable the splitting of MotionEvents to multiple children during touch event dispatch. This behavior is enabled by default for applications that target an SDK version of 11 (Honeycomb) or newer. On earlier platform versions this feature was not supported and this method is a no-op.

When this option is enabled MotionEvents may be split and dispatched to different child views depending on where each pointer initially went down. This allows for user interactions such as scrolling two panes of content independently, chording of buttons, and performing independent gestures on different pieces of content.

public static void setTransitionGroup(@NonNull ViewGroup group, boolean isTransitionGroup)

Changes whether or not this ViewGroup should be treated as a single entity during Activity Transitions.
