public WindowGroup(@NonNull
 Context context)

Method Details

dispatchTouchEvent

public boolean dispatchTouchEvent(@NonNull
 MotionEvent ev)

Description copied from class: View

Pass the touch screen motion event down to the target view, or this view if it is the target.

Overrides:

dispatchTouchEvent in class ViewGroup

Parameters:

ev - The motion event to be dispatched.

Returns:

true if the event was handled by the view, false otherwise

dispatchHoverEvent

protected boolean dispatchHoverEvent(@NonNull
 MotionEvent event)

Description copied from class: View

Dispatch a hover event.

Do not call this method directly. Call View.dispatchGenericMotionEvent(MotionEvent) instead.

Overrides:

dispatchHoverEvent in class ViewGroup

Parameters:

event - The motion event to be dispatched.

Returns:

True if the event was handled by the view, false otherwise.

dispatchGenericPointerEvent

protected boolean dispatchGenericPointerEvent(@NonNull
 MotionEvent event)

Description copied from class: View

Dispatch a generic motion event to the view under the first pointer.

Do not call this method directly. Call View.dispatchGenericMotionEvent(MotionEvent) instead.

Overrides:

dispatchGenericPointerEvent in class ViewGroup

Parameters:

event - The motion event to be dispatched.

Returns:

True if the event was handled by the view, false otherwise.

onResolvePointerIcon

public PointerIcon onResolvePointerIcon(@NonNull
 MotionEvent event)

Description copied from class: View

Returns the pointer icon for the motion event, or null if it doesn't specify the icon. The default implementation does not care the location or event types, but some subclasses may use it (such as WebViews).

Overrides:

onResolvePointerIcon in class ViewGroup

Parameters:

event - The MotionEvent from a mouse

See Also:

• PointerIcon

addView

public void addView(@NonNull
 View child,
 int index,
 @NonNull
 ViewGroup.LayoutParams params)

Description copied from class: ViewGroup

Adds a child view with the specified layout parameters.

Note: do not invoke this method from View.draw(Canvas), View.onDraw(Canvas), ViewGroup.dispatchDraw(Canvas) or any related method.

Overrides:

addView in class ViewGroup

Parameters:

child - the child view to add

index - the position at which to add the child or -1 to add last

params - the layout parameters to set on the child

onViewAdded

protected void onViewAdded(View child)

Description copied from class: ViewGroup

Called when a new child is added to this ViewGroup. Overrides should always call super.onViewAdded.

Overrides:

onViewAdded in class ViewGroup

Parameters:

child - the added child view

onRequestFocusInDescendants

protected boolean onRequestFocusInDescendants(int direction,
 Rect previouslyFocusedRect)

Description copied from class: ViewGroup

Look for a descendant to call View.requestFocus() on. Called by ViewGroup.requestFocus(int, Rect) when it wants to request focus within its children. Override this to customize how your ViewGroup requests focus within its children.

Overrides:

onRequestFocusInDescendants in class ViewGroup

Parameters:

direction - One of FOCUS_UP, FOCUS_DOWN, FOCUS_LEFT, and FOCUS_RIGHT

previouslyFocusedRect - The rectangle (in this View's coordinate system) to give a finer grained hint about where focus is coming from. May be null if there is no hint.

Returns:

Whether focus was taken.

onMeasure

protected void onMeasure(int widthMeasureSpec,
 int heightMeasureSpec)

Description copied from class: View

Measure the view and its content to determine the measured width and the measured height. This method is invoked by View.measure(int, int) and should be overridden by subclasses to provide accurate and efficient measurement of their contents.

CONTRACT: When overriding this method, you must call View.setMeasuredDimension(int, int) to store the measured width and height of this view. Failure to do so will trigger an IllegalStateException, thrown by View.measure(int, int). Calling super.onMeasure() is a valid use.

The base class implementation of measure defaults to the background size, unless a larger size is allowed by the MeasureSpec. Subclasses should override the base one to provide better measurements of their content.

Overrides:

onMeasure in class View

Parameters:

widthMeasureSpec - width measure specification imposed by the parent MeasureSpec

heightMeasureSpec - height measure specification imposed by the parent MeasureSpec

onLayout

protected void onLayout(boolean changed,
 int left,
 int top,
 int right,
 int bottom)

Description copied from class: View

Called from View.layout(int, int, int, int) when this view should assign a size and position to each of its children.

Derived classes with children should override this method and call layout on each of their children.

Specified by:

onLayout in class ViewGroup

Parameters:

changed - This is a new size or position for this view

left - Left position, relative to parent

top - Top position, relative to parent

right - Right position, relative to parent

bottom - Bottom position, relative to parent

requestChildFocus

public void requestChildFocus(View child,
 View focused)

Description copied from interface: ViewParent

Called when a child of this parent wants focus

Specified by:

requestChildFocus in interface ViewParent

Overrides:

requestChildFocus in class ViewGroup

Parameters:

child - The child of this ViewParent that wants focus. This view will contain the focused view. It is not necessarily the view that actually has focus.

focused - The view that is a descendant of child that actually has focus

clearChildFocus

public void clearChildFocus(View child)

Description copied from interface: ViewParent

Called when a child of this parent is giving up focus

Specified by:

clearChildFocus in interface ViewParent

Overrides:

clearChildFocus in class ViewGroup

Parameters:

child - The view that is giving up focus

clearFocus

public void clearFocus()

Description copied from class: View

Called when this view wants to give up focus. If focus is cleared View.onFocusChanged(boolean, int, Rect) is called.

Note: When not in touch-mode, the framework will try to give focus to the first focusable View from the top after focus is cleared. Hence, if this View is the first from the top that can take focus, then all callbacks related to clearing focus will be invoked after which the framework will give focus to this view.

Overrides:

clearFocus in class ViewGroup
