With reference to Fig. 1, a kind of stream of the touch event processing method embodiment 1 based on android system of the application is shown
Cheng Tu, may comprise steps of：
Step 101：Obtain the touch event of current triggering.
In the embodiment of the present application, when user triggers touch event on the touch screen of smart machine, obtain first
To the touch event of user's currently triggering.Wherein, touch event is referred to
Raw touch event.For example, active user opens wechat, then be accomplished by catching user in the present embodiment when front opening
Slip (move) event on wechat interface.And if user has been switched to the interface of Taobao from wechat, then in such case
Under the touch event that captures be exactly slip event that user is triggered on the interface of Taobao.Further for example, user is set in intelligence
Slip event when switching between the multi-screen of standby desktop application, etc..
Step 102：Judge whether current touch event is to press event, if pressing event, then into step 103.
Whether the current touch event to getting in step 101 is to press event to judge, if pressing event,
It is follow-up just to trigger the pre- flow gauge of touch event.In the present embodiment, touch event is divided into three kinds：Press, unclamp and move, work as product
Life can trigger touch event pre- flow gauge when pressing event.
Step 103：The triggering pre- flow gauge of touch event, the pre- flow gauge of the touch event can include：Judge last
Whether the time that touch event occurs is more than default touch time interval with the time difference of current time, if it is greater, then according to
According to default predicted events model prediction touch event next time.
In the present embodiment, when generate press event when, the pre- flow gauge of touch event of triggering may determine that first
Whether the time of touch event generation is more than a default touch time interval with the time difference of current time, for example
10ms, if this time difference is also bigger than default touch time interval, illustrates that the touch event that user produces has time delay,
In this case just occur interface on touch screen drafting is discontinuous or the situation of time delay, in order to avoid such case, just
Touch event next time can be predicted according to default predicted events model.For example, prediction touch event next time occurs
Position, that is, predict which position on current touch interface may produce touch event.
It is understood that the numerical value of touch time interval can be by those skilled in the art are according to actual demand or answer
Independently arranged with scene, for example, according to the cpu load situation of the android system to the default touch time interval
It is adjusted.Wherein, if cpu load is larger, can will touch that time interval arranges accordingly is somewhat a little bit smaller, and such as
Fruit cpu load is less, then can will touch the slightly larger of time interval setting accordingly.For example, when cpu load exceedes
When 70%, illustrate that the speed of the touch event of system response user can be slow, then now by the default touch time
Interval is adjusted to 10ms, thus can predict touch event next time faster, and if cpu load is less than or waits
In 70%, illustrate that the Performance comparision of system is good, it is inherently corresponding very fast to the touch event of user, now just can be by
Touch time interval and be adjusted to 20ms, less frequently touch event is predicted.Certainly, above-mentioned numerical value simply specifically shows
Example, should not be construed as the restriction to the application.
Step 104：The touch event next time of the prediction is defined as into pending touch event.
Then the touch event predicted in step 103 is just defined as pending touch event by system.
Using the embodiment of the present invention, when user carries out finger on touch apparatus to slide, once touch default
Touch and touch operation does not occur in time interval, will predict the position of the touch event that may occur next time, then by being
The touch event to the prediction of uniting is responded.So as to faster response user's operation on the touchscreen, so not
The response speed of system is only improved, the touch time of user is quickly made a response, so as to solve the touch operation of user
There is larger time delay, it is also possible to which the effect of the finger that user slides in Touch screen is clung in generation, so as to improve
The experience of user.
With reference to Fig. 2, a kind of stream of the touch event processing method embodiment 2 based on android system of the application is shown
Cheng Tu, the present embodiment is the specific example of embodiment 1, and this specific example may comprise steps of：
Step 201：Obtain the touch event of current triggering.
Step 202：Judge whether current touch event is to press event, if pressing event, then into step 203,
If not event is pressed, then into step 204.
Step 201～step 202 is consistent with embodiment 1, will not be described here.
Step 203：The pre- flow gauge of trigger event, and enter step 213.
In the present embodiment, event prediction flow process can adopt an independent prediction thread to realize.When need trigger thing
When part pre- flow gauge, the independent prediction thread is just triggered.It is understood that the independent prediction thread is in triggering
Afterwards, it can be determined that current setting exits mark, and whether such as user triggers release event, if it is, the prediction
Thread can stop, and if user does not trigger release event, then predict that thread can be got between the default touch time
Every, and get last time touch event generation time obtain time difference so as to subtract each other with current time.If the time difference is big
In time interval is touched, then can call default predicted events model to generate touch event next time, if time difference does not have
Have more than time interval is touched, then the independent prediction thread can enter dormancy, and the length of dormant event can be default
The length at touch event interval, so as to wait user to be next time waken up when event is pressed in generation.
Step 204：Judge whether the current touch event is release event, if it is, step 205 is entered, if
It is no, then into step 206.
In the present embodiment, if current touch event is not event of pressing, continuation judges that current touch event is not
It is release event.
Step 205：Stop the pre- flow gauge of touch event, and remove all touch events in the event queue, terminate
Current process.
If current touch event is release event, illustrate that user currently has been completed the operation to touch screen, then
The pre- flow gauge of touch event can now be stopped.
In the present embodiment, the event queue of a FIFO can be set up, and touch event is preserved successively to this
In event queue, then after the pre- flow gauge of touch event is stopped, the touch event in the event queue being reset, from
And it is convenient when trigger the pre- flow gauge of touch event next time, then touch event is stored toward the event queue.
Step 206：Determine that the current touch event is moving event, and judge the moving event with the presence or absence of correspondence
Prediction touch event, if it is present enter step 207, if it does not, terminate current process.
In current touch event neither pressing event nor in the case of release event, determining that current touch event is
Mobile (move) event, then, judge that the moving event, with the presence or absence of corresponding prediction touch event, is to judge whether also have
Predicted events and the moving event match.When implementing, predicted events can be put in prediction queue, when user triggers
During touch event, predicted events are taken out from the head of prediction queue, can be put in event queue together with touch event.Such as
No touch event in fruit prediction queue, then illustrate that the moving event does not have corresponding predicted events.
Step 207：Obtain the prediction touch event occurs between position and the generation position of the moving event
Pixel value difference.
When moving event has corresponding prediction touch event, the generation position of prediction touch event is got,
It is prediction abscissa X and vertical coordinate Y value of the touch event on touch-screen display interface, and same gets mobile thing
The generation position of part, is abscissa X and vertical coordinate Y value of the moving event on touch-screen display interface, by both coordinates
Value is subtracted each other and obtains pixel value difference.
Step 208：Whether the pixel value difference is judged more than default error threshold, if it is, step 209 is entered,
If it is not, then terminating current process.
Judge whether the pixel value difference that step 207 is obtained is more than default error threshold.The error threshold can be with value as 5
～8, generally, 5～8 pixels when user's finger is pressed, can be covered on the interface of touch screen.If it is not greater, then
Terminate current process.
Step 209：The prediction touch event is recorded as into anomalous event.
When pixel value difference is more than default error threshold, for example, have been above the picture covered when user averagely touches
Vegetarian refreshments region, then illustrate that this prediction touch event is relatively not accurate enough, in this case, by the prediction touch event
It is recorded as anomalous event.
Step 210：Whether the frequency of the anomalous event is judged more than predeterminated frequency threshold value, if it is, entering step
211, if it is not, then entering step 212.
In actual applications, if continuously all there is anomalous event several times, the frequency for being anomalous event is more than default frequency
Rate threshold value, for example, has 3 to be all anomalous event in nearest continuous 8 predictions touch event, and possible predicted events model is selected
It is not accurate enough.
Step 211：The event used when default higher-order function model is defined as the pre- flow gauge of trigger event next time
Forecast model, terminates current process.
When the number of times that anomalous event occurs is more, just using default higher-order function model as predicted events mould
Type, in the pre- flow gauge of upper once trigger event, will predict the generation of touch event using default higher-order function model
Position.
Step 212：The event used during using flow gauge default linear function model pre- as trigger event next time is pre-
Model is surveyed, terminates current process.
When the number of times that anomalous event occurs is less, just using default linear function model as predicted events mould
Type, in the pre- flow gauge of next trigger event, will predict the generation position of touch event using default linear function model
Put.
Step 213：The touch event next time of the prediction is defined as into pending touch event.
When touch event is predicted, just using the touch event next time of prediction as pending touch event.
It is follow-up in the real touch event of user and when be not transferred to input window processor, just directly in response to the touch of the prediction
Event.
Using the embodiment of the present invention, response user's operation on the touchscreen that can not only be faster improves system
Response speed, the touch time of user is quickly made a response, so as to the touch operation for solving user has larger time delay
Problem, it is also possible to the effect of the finger that user slides in Touch screen is clung in generation, so as to improve the use body of user
