ViewGroupCompat

• java.lang.Object

Fields Summary
public static final int	LAYOUT_MODE_CLIP_BOUNDS This constant is a {@link #setLayoutMode(ViewGroup, int) layoutMode}. Clip bounds are the raw values of {@link android.view.View#getLeft() left}, {@link android.view.View#getTop() top}, {@link android.view.View#getRight() right} and {@link android.view.View#getBottom() bottom}.
public static final int	LAYOUT_MODE_OPTICAL_BOUNDS This constant is a {@link #setLayoutMode(ViewGroup, int) 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.
static final ViewGroupCompatImpl	IMPL

Constructors Summary
private ViewGroupCompat() final int version = Build.VERSION.SDK_INT; if (version >= 21) { IMPL = new ViewGroupCompatApi21Impl(); } else if (version >= 18) { IMPL = new ViewGroupCompatJellybeanMR2Impl(); } else if (version >= 14) { IMPL = new ViewGroupCompatIcsImpl(); } else if (version >= 11) { IMPL = new ViewGroupCompatHCImpl(); } else { IMPL = new ViewGroupCompatStubImpl(); }

Methods Summary
public static int	getLayoutMode(android.view.ViewGroup group) Returns the basis of alignment during layout operations on this ViewGroup: either {@link #LAYOUT_MODE_CLIP_BOUNDS} or {@link #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 {@link #LAYOUT_MODE_CLIP_BOUNDS}. return the layout mode to use during layout operations see #setLayoutMode(ViewGroup, int) return IMPL.getLayoutMode(group);
public static boolean	isTransitionGroup(android.view.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. return IMPL.isTransitionGroup(group);
public static boolean	onRequestSendAccessibilityEvent(android.view.ViewGroup group, android.view.View child, android.view.accessibility.AccessibilityEvent event) Called when a child has requested sending an {@link AccessibilityEvent} and gives an opportunity to its parent to augment the event. If an {@link AccessibilityDelegateCompat} has been specified via calling {@link ViewCompat#setAccessibilityDelegate(View, AccessibilityDelegateCompat)} its {@link AccessibilityDelegateCompat#onRequestSendAccessibilityEvent(ViewGroup, View, AccessibilityEvent)} is responsible for handling this call. param group The group whose method to invoke. param child The child which requests sending the event. param event The event to be sent. return True if the event should be sent. return IMPL.onRequestSendAccessibilityEvent(group, child, event);
public static void	setLayoutMode(android.view.ViewGroup group, int mode) Sets the basis of alignment during the layout of this ViewGroup. Valid values are either {@link #LAYOUT_MODE_CLIP_BOUNDS} or {@link #LAYOUT_MODE_OPTICAL_BOUNDS}. param mode the layout mode to use during layout operations see #getLayoutMode(ViewGroup) IMPL.setLayoutMode(group, mode);
public static void	setMotionEventSplittingEnabled(android.view.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. param group ViewGroup to modify param split true to allow MotionEvents to be split and dispatched to multiple child views. false to only allow one child view to be the target of any MotionEvent received by this ViewGroup. IMPL.setMotionEventSplittingEnabled(group, split);
public static void	setTransitionGroup(android.view.ViewGroup group, boolean isTransitionGroup) Changes whether or not this ViewGroup should be treated as a single entity during Activity Transitions. param isTransitionGroup Whether or not the ViewGroup should be treated as a unit in Activity transitions. If false, the ViewGroup won't transition, only its children. If true, the entire ViewGroup will transition together. IMPL.setTransitionGroup(group, isTransitionGroup);
