Helper for accessing features in View.

Summary

Nested classes
abstract	`OnUnhandledKeyEventListenerCompat` Interface definition for a callback to be invoked when a hardware key event hasn't been handled by the view hierarchy.

Constants
static Int	`ACCESSIBILITY_LIVE_REGION_ASSERTIVE` Live region mode specifying that accessibility services should interrupt ongoing speech to immediately announce changes to this view.
static Int	`ACCESSIBILITY_LIVE_REGION_NONE` Live region mode specifying that accessibility services should not automatically announce changes to this view.
static Int	`ACCESSIBILITY_LIVE_REGION_POLITE` Live region mode specifying that accessibility services should announce changes to this view.
static Int	`IMPORTANT_FOR_ACCESSIBILITY_AUTO` Automatically determine whether a view is important for accessibility.
static Int	`IMPORTANT_FOR_ACCESSIBILITY_NO` The view is not important for accessibility.
static Int	`IMPORTANT_FOR_ACCESSIBILITY_NO_HIDE_DESCENDANTS` The view is not important for accessibility, nor are any of its descendant views.
static Int	`IMPORTANT_FOR_ACCESSIBILITY_YES` The view is important for accessibility.
static Int	`LAYER_TYPE_HARDWARE` Indicates that the view has a hardware layer.
static Int	`LAYER_TYPE_NONE` Indicates that the view does not have a layer.
static Int	`LAYER_TYPE_SOFTWARE` Indicates that the view has a software layer.
static Int	`LAYOUT_DIRECTION_INHERIT` Horizontal layout direction of this view is inherited from its parent.
static Int	`LAYOUT_DIRECTION_LOCALE` Horizontal layout direction of this view is from deduced from the default language script for the locale.
static Int	`LAYOUT_DIRECTION_LTR` Horizontal layout direction of this view is from Left to Right.
static Int	`LAYOUT_DIRECTION_RTL` Horizontal layout direction of this view is from Right to Left.
static Int	`MEASURED_HEIGHT_STATE_SHIFT` Bit shift of `MEASURED_STATE_MASK` to get to the height bits for functions that combine both width and height into a single int, such as `getMeasuredState` and the childState argument of `resolveSizeAndState(int, int, int)`.
static Int	`MEASURED_SIZE_MASK` Bits of `getMeasuredWidthAndState` and `getMeasuredWidthAndState` that provide the actual measured size.
static Int	`MEASURED_STATE_MASK` Bits of `getMeasuredWidthAndState` and `getMeasuredWidthAndState` that provide the additional state bits.
static Int	`MEASURED_STATE_TOO_SMALL` Bit of `getMeasuredWidthAndState` and `getMeasuredWidthAndState` that indicates the measured size is smaller that the space the view would like to have.
static Int	`OVER_SCROLL_ALWAYS` Always allow a user to over-scroll this view, provided it is a view that can scroll.
static Int	`OVER_SCROLL_IF_CONTENT_SCROLLS` Allow a user to over-scroll this view only if the content is large enough to meaningfully scroll, provided it is a view that can scroll.
static Int	`OVER_SCROLL_NEVER` Never allow a user to over-scroll this view.
static Int	`SCROLL_AXIS_HORIZONTAL` Indicates scrolling along the horizontal axis.
static Int	`SCROLL_AXIS_NONE` Indicates no axis of view scrolling.
static Int	`SCROLL_AXIS_VERTICAL` Indicates scrolling along the vertical axis.
static Int	`SCROLL_INDICATOR_BOTTOM` Scroll indicator direction for the bottom edge of the view.
static Int	`SCROLL_INDICATOR_END` Scroll indicator direction for the ending edge of the view.
static Int	`SCROLL_INDICATOR_LEFT` Scroll indicator direction for the left edge of the view.
static Int	`SCROLL_INDICATOR_RIGHT` Scroll indicator direction for the right edge of the view.
static Int	`SCROLL_INDICATOR_START` Scroll indicator direction for the starting edge of the view.
static Int	`SCROLL_INDICATOR_TOP` Scroll indicator direction for the top edge of the view.
static Int	`TYPE_NON_TOUCH` Indicates that the input type for the gesture is caused by something which is not a user touching a screen.
static Int	`TYPE_TOUCH` Indicates that the input type for the gesture is from a user touching the screen.

open static ViewPropertyAnimatorCompat	`animate(@NonNull view: View)` This method returns a ViewPropertyAnimator object, which can be used to animate specific properties on this View.
open static Boolean	`canScrollHorizontally(view: View!, direction: Int)` Check if this view can be scrolled horizontally in a certain direction.
open static Boolean	`canScrollVertically(view: View!, direction: Int)` Check if this view can be scrolled vertically in a certain direction.
open static Unit	`cancelDragAndDrop(@NonNull v: View)` Cancel the drag and drop operation.
open static Int	`combineMeasuredStates(curState: Int, newState: Int)` Merge two states as returned by `getMeasuredState(View)`.
open static WindowInsetsCompat	`computeSystemWindowInsets(@NonNull view: View, @NonNull insets: WindowInsetsCompat, @NonNull outLocalInsets: Rect)` Compute insets that should be consumed by this view and the ones that should propagate to those under it.
open static WindowInsetsCompat	`dispatchApplyWindowInsets(@NonNull view: View, @NonNull insets: WindowInsetsCompat)` Request to apply the given window insets to this view or another view in its subtree.
open static Unit	`dispatchFinishTemporaryDetach(@NonNull view: View)` Notify a view that its temporary detach has ended; the view is now reattached.
open static Boolean	`dispatchNestedFling(@NonNull view: View, velocityX: Float, velocityY: Float, consumed: Boolean)` Dispatch a fling to a nested scrolling parent.
open static Boolean	`dispatchNestedPreFling(@NonNull view: View, velocityX: Float, velocityY: Float)` Dispatch a fling to a nested scrolling parent before it is processed by this view.
open static Boolean	`dispatchNestedPreScroll(@NonNull view: View, dx: Int, dy: Int, @Nullable consumed: IntArray?, @Nullable offsetInWindow: IntArray?)` Dispatch one step of a nested scroll in progress before this view consumes any portion of it.
open static Boolean	`dispatchNestedPreScroll(@NonNull view: View, dx: Int, dy: Int, @Nullable consumed: IntArray?, @Nullable offsetInWindow: IntArray?, type: Int)` Dispatch one step of a nested scroll in progress before this view consumes any portion of it.
