dispatchNestedScroll
Dispatch one step of a nested scroll in progress.
This version of the method just calls dispatchNestedScroll using the touch input type.
Return
true if the event was dispatched, false if it could not be dispatched.
Parameters
view for which to dispatch the scroll.
Horizontal distance in pixels consumed by this view during this scroll step
Vertical distance in pixels consumed by this view during this scroll step
Horizontal scroll distance in pixels not consumed by this view
Horizontal scroll distance in pixels not consumed by this view
Optional. If not null, on return this will contain the offset in local view coordinates of this view from before this operation to after it completes. View implementations may use this to adjust expected input coordinate tracking.
Dispatch one step of a nested scroll in progress.
Implementations of views that support nested scrolling should call this to report info about a scroll in progress to the current nested scrolling parent. If a nested scroll is not currently in progress or nested scrolling is not enabled for this view this method does nothing.
Compatible View implementations should also call dispatchNestedPreScroll before consuming a component of the scroll event themselves.
A non-null consumed int array of length 2 may be passed in to enable nested scrolling parents to report how much of the scroll distance was consumed. The original caller (where the input event was received to start the scroll) should initialize the values to be 0, in order to tell how much was actually consumed up the hierarchy of scrolling parents.
Parameters
view for which to dispatch the scroll.
Horizontal distance in pixels consumed by this view during this scroll step
Vertical distance in pixels consumed by this view during this scroll step
Horizontal scroll distance in pixels not consumed by this view
Horizontal scroll distance in pixels not consumed by this view
Optional. If not null, on return this will contain the offset in local view coordinates of this view from before this operation to after it completes. View implementations may use this to adjust expected input coordinate tracking.
the type of input which cause this scroll event
Output, If not null, consumed[0] will contain the consumed component of dx and consumed[1] the consumed dy.

Return
true if the event was dispatched, and therefore the scroll distance was consumed
Parameters
