dispatchDependentViewsChanged

void dispatchDependentViewsChanged (View view)

Allows the caller to manually dispatch onDependentViewChanged(CoordinatorLayout, View, View) to the associated CoordinatorLayout.Behavior instances of views which depend on the provided View.

You should not normally need to call this method as the it will be automatically done when the view has changed.

doViewsOverlap

boolean doViewsOverlap (View first, 
                View second)

Check whether two views overlap each other. The views need to be descendants of this CoordinatorLayout in the view hierarchy.

generateLayoutParams

CoordinatorLayout.LayoutParams generateLayoutParams (AttributeSet attrs)

getDependencies

List<View> getDependencies (View child)

Returns the list of views which the provided view depends on. Do not store this list as its contents may not be valid beyond the caller.

getDependents

List<View> getDependents (View child)

Returns the list of views which depend on the provided view. Do not store this list as its contents may not be valid beyond the caller.

getStatusBarBackground

Drawable getStatusBarBackground ()

Gets the drawable used to draw in the insets area for the status bar.

isPointInChildBounds

boolean isPointInChildBounds (View child, 
                int x, 
                int y)

Check if a given point in the CoordinatorLayout's coordinates are within the view bounds of the given direct child view.

onAttachedToWindow

void onAttachedToWindow ()

onDetachedFromWindow

void onDetachedFromWindow ()

onDraw

void onDraw (Canvas c)

onLayoutChild

void onLayoutChild (View child, 
                int layoutDirection)

Called to lay out each individual child view unless a Behavior is present. The Behavior may choose to delegate child measurement to this method.

onMeasureChild

void onMeasureChild (View child, 
                int parentWidthMeasureSpec, 
                int widthUsed, 
                int parentHeightMeasureSpec, 
                int heightUsed)

Called to measure each individual child view unless a Behavior is present. The Behavior may choose to delegate child measurement to this method.

onNestedPreScroll

void onNestedPreScroll (View target, 
                int dx, 
                int dy, 
                int[] consumed, 
                int type)

React to a nested scroll in progress before the target view consumes a portion of the scroll.

When working with nested scrolling often the parent view may want an opportunity to consume the scroll before the nested scrolling child does. An example of this is a drawer that contains a scrollable list. The user will want to be able to scroll the list fully into view before the list itself begins scrolling.

onNestedPreScroll is called when a nested scrolling child invokes dispatchNestedPreScroll(int, int, int[], int[]). The implementation should report how any pixels of the scroll reported by dx, dy were consumed in the consumed array. Index 0 corresponds to dx and index 1 corresponds to dy. This parameter will never be null. Initial values for consumed[0] and consumed[1] will always be 0.

onNestedScroll

void onNestedScroll (View target, 
                int dxConsumed, 
                int dyConsumed, 
                int dxUnconsumed, 
                int dyUnconsumed, 
                int type)

React to a nested scroll in progress.

This method will be called when the ViewParent's current nested scrolling child view dispatches a nested scroll event. To receive calls to this method the ViewParent must have previously returned true for a call to onStartNestedScroll(View, View, int, int).

Both the consumed and unconsumed portions of the scroll distance are reported to the ViewParent. An implementation may choose to use the consumed portion to match or chase scroll position of multiple child elements, for example. The unconsumed portion may be used to allow continuous dragging of multiple scrolling or draggable elements, such as scrolling a list within a vertical drawer where the drawer begins dragging once the edge of inner scrolling content is reached.

onNestedScrollAccepted

void onNestedScrollAccepted (View child, 
                View target, 
                int nestedScrollAxes, 
                int type)

React to the successful claiming of a nested scroll operation.

This method will be called after onStartNestedScroll returns true. It offers an opportunity for the view and its superclasses to perform initial configuration for the nested scroll. Implementations of this method should always call their superclass's implementation of this method if one is present.

onStartNestedScroll

boolean onStartNestedScroll (View child, 
                View target, 
                int axes, 
                int type)

React to a descendant view initiating a nestable scroll operation, claiming the nested scroll operation if appropriate.

This method will be called in response to a descendant view invoking startNestedScroll(View, int). Each parent up the view hierarchy will be given an opportunity to respond and claim the nested scrolling operation by returning true.

This method may be overridden by ViewParent implementations to indicate when the view is willing to support a nested scrolling operation that is about to begin. If it returns true, this ViewParent will become the target view's nested scrolling parent for the duration of the scroll operation in progress. When the nested scroll is finished this ViewParent will receive a call to onStopNestedScroll(View, int).

onStopNestedScroll

void onStopNestedScroll (View target, 
                int type)

React to a nested scroll operation ending.

Perform cleanup after a nested scrolling operation. This method will be called when a nested scroll stops, for example when a nested touch scroll ends with a ACTION_UP or ACTION_CANCEL event. Implementations of this method should always call their superclass's implementation of this method if one is present.

setStatusBarBackground

void setStatusBarBackground (Drawable bg)

Set a drawable to draw in the insets area for the status bar. Note that this will only be activated if this DrawerLayout fitsSystemWindows.

setStatusBarBackgroundColor

void setStatusBarBackgroundColor (int color)

Set a drawable to draw in the insets area for the status bar. Note that this will only be activated if this DrawerLayout fitsSystemWindows.

setStatusBarBackgroundResource

void setStatusBarBackgroundResource (int resId)

Set a drawable to draw in the insets area for the status bar. Note that this will only be activated if this DrawerLayout fitsSystemWindows.
