creating an event object in response to the
user input;
determining whether the event object
invokes a scroll or gesture operation by
distinguishing between a single input point
applied to the touch-sensitive display that
is interpreted as the scroll operation and
two or more input points applied to the
touch-sensitive display that are interpreted
as the gesture operation;

Samsung Galaxy Tab 10.1
The Samsung device, via the Android platform on which the device operates, creates
an event object in response to the user input and determines whether the event object
invokes a scroll or gesture operation by distinguishing between a single input point
(single finger) applied to the touch-sensitive display that is interpreted as the scroll
operation and two or more input points (two or more fingers) applied to the touchsensitive display that are interpreted as the gesture operation.
As an example, under the Android platform, a MotionEvent object is created in
response to a touch on the touchscreen. (Android Developers Site at Class
MotionEvent)(Available at
http://developer.android.com/reference/android/view/MotionEvent.html.)

The Samsung Galaxy Tab 10.1 has source code that enables it to “creating
an event object in response to the user input.” On the Galaxy Tab 10.1
tablet, user input is processed by the device driver, which passes the input into
user space and parses it into an event object referred to as the “MotionEvent”
object. This object is an event object created by the method

[SAMNDCA-C000002830 to -C000002831] (MotionEvent::initialize()

The Samsung Galaxy Tab 10.1 has source code that enables it to
“determining whether the event object invokes a scroll or gesture
operation by distinguishing between a single input point applied to the
touch-sensitive display that is interpreted as the scroll operation and two
or more input points applied to the touch-sensitive display that are
interpreted as the gesture operation.”
On the Galaxy Tab 10.1 tablet, the WebView class’s
handleQueuedMotionEvent() method interprets the input points associated with
the MotionEvent object it processes. The handleQueueMotionEvent() method
distinguishes between a single input point (ev.getPointerCount == 1) and two or
more input points (ev.getPointerCount > 1). (See WebView.java:10281-10314
[SAMDNCA-C000002857].) If one input point is detected, the contact is
interpreted as a scroll operation in handleTouchEventCommon(). (See
WebView.java:10312 [SAMNDCA-C000002857].) If two or more input points
are detected, the contact is interpreted as a gesture operation via a call to
handleMultiTouchInWebView(). (See WebView.java:10302 [SAMNDCAC000002857]; WebView.java:7887-7944 [SAMNDCA-C000002858].)

handleQueuedMotionEvent() will call handleTouchEventCommon()
(WebView.java:10312 [SAMNDCA-C000002926]), which issue a scroll call to
doDrag() or doFling(). (WebView.java:7617, 7772 [SAMNDCA-C000002926,
-C000002930]) If two or more input points are detected, the contact is
interpreted as a gesture operation and issue a call to
handleMultiTouchInWebView(). (See WebView.java:10302 [SAMNDCAC000002857]; WebView.java:7887-7944 [SAMNDCA-C000002858].)
The Samsung Galaxy Tab 10.1 has source code that enables it to respond
“to at least one scroll call, if issued, by scrolling a window having a view
associated with the event object based on an amount of a scroll with the
scroll stopped at a predetermined position in relation to the user input”
On the Galaxy 10.1 tablet, the handleTouchEventCommon() method calls
doFling() for a scroll operation. (See WebView.java:7272-7821 [SAMNDCAC000002919 to –C000002931] (call done at 7772).) doFling() then calls the
Overscroller.fling() method. (See WebView.java:9236-9376 [SAMNDCAC000002932 to –C000002935].) Overscroller.fling() itself calls two instances
of the SplineOverScroller class, each of which is responsible for scrolling in
one axis (i.e., one scrolls horizontally and the other scrolls vertically). (See
OverScroller.java:406-448 [SAMNDCA-C000002945].) The
SplineOverScroller class thus maintains state information for the fling. (See
id.)
The SplineOverScroller class tracks the start points, start time, duration, total
distance, and the final position for the scroll at the end of the fling operation.
(OverScroller.java:748-782 [SAMNDCA-C000002952 to –C000002953].) The
SplineOverScroller.fling() function thus determines the final position of the
fling before beginning the fling operation.
The actual rendering of the fling occurs subsequently as part of the drawing
cycle. At the end of an event processing cycle, the method computeScroll() is
called to compute which part of the view should be rendered to the user. (See
WebView.java:3568-3654 [SAMNDCA-C000002958 to –C000002959]. The
computeScroll() method uses the SplineOverScroller class to extract the state
information for the fling. (See id.) Afterwards, it calls



Samsung Galaxy Tab 10.1
WebView.overScrollBy() to scroll the content—this method calculates
maximums for the distance the user can scroll beyond the edge of the content
and whether content should be fixed to a particular axis. (See id.; see also
View.java:11663-11715 [SAMNDCA-C000002960 to –C000002961]
(WebView.overScrollBy()).) onOverScrollBy() itself calls onOverScroller() to
ensure the intended scroll coordinates are valid and then calls View.scrollTo()
to invoke the scroll operation. (See View.java:11663-11715 [SAMNDCAC000002960 to –C000002961]; WebView.java:3130-3162 [SAMDNCA2962].) View.scrollTo() scrolls the window (setting mScrollX and mScrollY)
based on the amount of a scroll with the scroll stopped at a “predetermined
position in relation to the user input.” (See WebView.java:3130-3162
[SAMDNCA-2962].)
Alternatively, the scroll stops at a “predetermined position in relation to the
user input” because after the mScrollX and mScrollY fields are set (or
determined), the WebView.onDraw() method is subsequently called to translate
and draw the view shown to the user. (See WebView.java:4261-4418
[SAMNDCA-C000002965 to –C000002968] (with call to trackFPS() at 4416);
WebView.java:8757-8791 [SAMNDCA-C000002964] (trackFPS() translates

On the Galaxy 10.1 tablet, the handleMultiTouchInWebView() method calls the
WebViewScaleGestureDecetor.onTouchEvent() method to perform the scaling
(zoom) operation using the MotionEvent object information, which includes the
two or more input points touching the screen. (See
WebViewScaleGestureDetector.java:189 [SAMNDCA-C000002905].)
onTouchEvent() calls setContext(), which records information about the

Samsung Galaxy Tab 10.1
position of the two input points corresponding, for example, to the user’s
fingers on the screen (WebviewScaleGestureDetector.java:581-630
[SAMNDCA-C000002524 to -C000002525]). As the user moves his fingers
relative to one another—as in, for example, a pinching or de-pinching gesture—
the handleScale() method of the ZoomManager class calls the
WebviewScaleGestureDetector’s getScaleFactor() method to calculate the scale
factor based on the ratio of the current distance between the fingers and the
previous distance between them (as of the last time the touch screen was polled
for input). (ZoomManager.java:1323 [SAMNDCA-C000002410];
WebScaleGestureDetector.java:763-768 [SAMNDCA-C000002528].)
handleScale() then calls setZoomScale(), which uses the calculated scale factor
to scale the WebView and all of its child views. ZoomManager.java:1372
[SAMNDCA-C000002411]; ZoomManager.java:851-949 [SAMNDCAC000002399 to -C000002402].)

The predetermined maximum displacement is defined in the Galaxy Tab 10.1
tablet source code to be 1/6 the height and 1/6 the width of the screen for a fling
(i.e., a quick, flicking motion of the user’s finger on the screen that causes the
view to scroll a predetermined distance without further user input). The
handleTouchEventCommon() method calls doFling(). (See
WebView.java:7272-7821 [SAMNDCA-C000002919 to -C000002931] (call
done at 7772).) In the doFling() method, if the isElasticEffectEnabled() method

variables are then passed to the Overscroller.fling() method, and they set the
