The present invention is used in touch type flat computing machine (Tablet PC), intelligent mobile phone (Smart Phone) and Touch Screen computing machine (Touch-Screen PC).Following the disclosed embodiments be iPad flat computer pattern taking apple as example, its picture feature of all the other touch-control devices also with, therefore describe no longer separately and narrate.
Consult Fig. 5 A, the embodiment of the present invention is located the financial tape reading device 26 systemic-function calcspars of scrolling view best image position automatically, and it includes: display module 28, processor (being the abbreviation of central processing unit) 30 and internal memory 32.Wherein, internal memory 32 stores a financial tape reading software 34; 30 of processors are responsible for carrying out the financial tape reading software 34 in internal memory 32; 28 of display modules are in order to show the interface (screen-picture) of financial tape reading software 34, and carry out the function (contact panel) of touch-control.
Consult Fig. 5 B, the systemic-function calcspar of embodiment of the present invention financial tape reading software 34, it has illustrated that the present invention and prior art (as shown in Figure 4) difference are that the present invention replaces the scrolling view operation module 24 of prior art with a scrolling view operation and locating module 36.This scrolling view operation and locating module 36 are received in the slide instruction that this scrolling view touching produces, carry out the scrolling of this scrolling view according to this slide instruction, and receive a call back function return (A Callback Function Return) (that is, the side-play amount of scrolling view, in order to calculate its stop position) after the best image position of this scrolling view to minimum distance of fine tune, and download the quote data of demonstration information in this best image position of this scrolling view.This call back function returns and is defined by operating system API (Application ProgrammingInterfaces), scrolling view operation and locating module 36 require operating system after the slide instruction producing because of touching is provided in the time carrying out, once meet specified conditions, operating system transmit call back function and return to scrolling view operation and locating module 36.It is the embodiment of iOS operating system that following call back function returns, and method of the present invention also can be applicable to the call back function that other operating systems are equal and returns or call back function parameter.
Wherein, this scrolling view is to be selected from: a quotation information view 14 and a Detail View 18, certainly, technology disclosed in this invention also can be applicable to the scrolling view of other types.
With the present invention's one iPad flat computer (operation iOS operating system), embodiment illustrates, wants altogether two call back functions of implementation (Callback Function): scrollViewDidEndDecelerating and scrollViewDidEndDragging." scrollViewDidEndDecelerating refers to while stopping sliding " have slide and ", its fragment program code example is as follows:
" calculateScrollViewOffset " using in above procedure code is the side-play amount (Offset that calculates scrolling view, claim again displacement, view displacement how many distances), by this side-play amount can learn this scrolling view in slide after stop position.Scrolling view operation of the present invention and locating module 36 return after (i.e. the side-play amount of a scrolling view) at the above-mentioned call back function of reception, the scrolling view of " having stopped sliding " can be readjusted by a small margin to (meaning is automatic coiling) again to a nearest best image position.It is to be produced by operating system that aforesaid call back function returns, and after receiving call back function and returning, can confirm that user " has stopped sliding ", now, then carries out the fine tune of scrolling view.
Please refer to Fig. 6 A, it is the schematic diagram one of the embodiment of the present invention one scrolling view (quotation information view), and legend is that the iPad touch type flat computing machine of adopting apple is example.This embodiment has illustrated that the free quotation view 38 of financial tape reading software 34 of the present invention has comprised a title block, a quotation information view 40, a horizontal roll moving axis 16 and a menu bar.Wherein, quotation information view 40 is a UITableView classification in iOS program development, and this UITableView classification is inherited from UIScrollView classification (i.e. a scrolling view).This quotation information view 40 shows quotation information with a scrolling view, and in the time that its information comprising exceeds screen-picture, user can slide (Slide) operation with this scrolling view switching demonstration information of scrolling.And the production process of this quotation information view 40, be first to receive the quote data by the client that push server reaches of server end by data reception module 20, then produce a scrolling view (being quotation information view 40) by scrolling views module 22 according to this quote data.Horizontal roll moving axis 16 is mark this scrolling view (being quotation information view 40) positions of shown data instantly, but not is directly used in slide.The horizontal roll moving axis 16 of this legend is positioned at the leftmost meaning of view: this quotation information view 40 is the information that shows leftmost instantly, and the right-hand information not being shown on screen that still has.With existing one (being Figure 1A) relatively, before slide not, it has no difference with prior art scrolling view of the present invention (being quotation information view 40) in appearance.
Please refer to Fig. 6 B and Fig. 6 C, this two figure is the continuous schematic diagram of the embodiment of the present invention one its movement decomposition picture of scrolling view, and this two figure is Figure 1B of contrast prior art one.Fig. 6 B is that explanation user is the field of checking quotation information view 40 the right, thereby quotation information view 40 in slip Fig. 6 A is to right-hand (power that this step hypothesis user slides is identical with the Figure 1B that operates existing).The process of slide is that scrolling view operation and locating module 36 receive after a slide instruction of this quotation information view 40, carry out the scrolling of this quotation information view 40 according to this slide instruction, in the time that slip stops, (why conventionally understand for the convenience of the user the corresponding financial products of quotation information, " title " field is to maintain static to screen-picture as shown in Figure 6B.Therefore the slidably field of high order end is " selling ").Then, aforementioned scrollViewDidEndDecelerating and scrollViewDidEndDragging two call back functions stop in slip after (while stopping sliding " have slide and " or " when stopping towing and not sliding ") selecting an execution and returning to the side-play amount of this quotation information view 40 depending on trigger condition, this side-play amount is that call back function returns to calculate its stop position, and scrolling view operation and locating module 36 return and calculate from the nearest best image position of stop position according to this call back function again.Taking Fig. 6 B as example, this quotation information view 40 slidably field leftmost " selling " and rightmost " amplitude " two fields is all cut off a part of information and seems imperfect, learns afterwards as calculated the part that " selling " field on the left side presents on screen more (nearer apart from screen center's point of content slidably).Therefore, this quotation information view 40 that scrolling view operation and locating module 36 stop for sliding is readjusted by a small margin position to till showing complete " selling " field, and the screen-picture after adjustment as shown in Figure 6 C.
That is, scrolling view operation and locating module 36 determine the mode of " nearest best image position ", the most left and rightmost field while relatively horizontally slipping, its information shows incomplete field size ratio, expose and show that the greater carries out field completely and shows with field, thereby determine " best image position ".For example, when the most left field displaying ratio is 60%, and the rightest field displaying ratio is 40%, shows completely with the most left field and carries out automatic coiling.If just the most left field is when the displaying ratio of right field is all 50%, can gives tacit consent to the most left field of demonstration and hide the rightest field; Or acquiescence shows the rightest field and hides the most left field.
With regard to another embodiment, also can give tacit consent to the most left field for showing completely, thus definition " nearest best image position "; Or the rightest field of acquiescence is for showing completely, thus definition " nearest best image position ".
Figure 1B of Fig. 6 B of the embodiment of the present invention one and Fig. 6 C and existing one is done to one relatively, can find that the two ends, left and right of existing quotation information view 14 all show Incomplete information (as shown in Figure 1B) after slip stops when user is with the power (being the speed of sliding speed) of same slide.And quotation information view 40 of the present invention is after slip stops, on screen only of short duration demonstration as the picture of Fig. 6 B, and then scrolling view operation and locating module 36 readjust by a small margin the nearest best image position (as shown in Figure 6 C) of scrolling view to, coming 6B with the aid of pictures and Fig. 6 C with user's naked eyes is the picture occurring in succession, and user is difficult for discovering centre the extremely of short duration best image position that stops being adjusted at once.Therefore, user's slide scrolling view of the present invention does not need to make another skillful opening and slides to do the fine tune of position, gets final product automatic fine tuning to best image position by technology of the present invention.
Consult Fig. 7 A, the schematic diagram one of the embodiment of the present invention two scrolling views (Detail View), to be explanation click in quotation information view 40 after financial products in free quotation view 38 (as shown in Figure 6A) as user for it, below free quotation view 38, ejecting a Detail View 42 this is clicked financial products (legend is " Bank of China " to show, therefore to highlight demonstration) its personal share details are (for example: tendency quotation, timesharing detail, five grades of Pan Kou, the information such as valency amount statistics and technical Analysis), the shown details of legend are " tendency quotation " and " timesharing detail ".This Detail View 42 is also a scrolling view (being to be defined as UIScrollView classification in iOS program development), and user can show with scrolling view handover information by left/right slide.The horizontal roll moving axis 16 of this view below represents this Detail View 42 position that information shows instantly, and in legend, this horizontal roll moving axis 16 is positioned at Far Left and represents that this Detail View 42 is to show leftmost information instantly.And the production process of this Detail View 42, be first to receive the quote data by client that server end reaches by data reception module 20, then produce a scrolling view (being Detail View 42) by scrolling views module 22 according to this quote data.With existing two (being Fig. 2 A) relatively, similarly, before slide not, it has no difference with prior art scrolling view of the present invention (being Detail View 42) in appearance.
Consult Fig. 7 B and Fig. 7 C, this two figure is the continuous schematic diagram of the embodiment of the present invention two its movement decomposition pictures of scrolling view, and this two figure is Fig. 2 B of contrast prior art two.Fig. 7 B is that user slides a little in the Detail View 42 of Fig. 7 A, scrolling view operation and locating module 36 receive a slide instruction of this Detail View 42, the scrolling of carrying out this Detail View 42 according to this slide instruction, in the time that slip stops, screen-picture temporarily as shown in Figure 7 B.Instantly shown only one " the timesharing detail " of complete details of this Detail View 42, its left side " tendency quotation " is all cut off half and cannot completely presents (there is no the whole screen that is arranged in) with the right " five grades of Pan Kou ".And then, scrollViewDidEndDecelerating and scrollViewDidEndDragging two call back functions stop in slip after (while stopping sliding " have slide and " or " when stopping towing and not sliding ") selecting an execution and returning to the side-play amount (call back function returns) of this Detail View 42 depending on trigger condition, and scrolling view operation and locating module 36 return to calculating from the nearest best image position of stop position according to this call back function again.Taking Fig. 7 B as example, " five grades of Pan Kou " two fields on " the tendency quotation " on these Detail View 42 left sides and the right are all cut off a part of information and seem imperfect, learn afterwards as calculated the part that " five grades of Pan Kou " on the right present on screen more (nearer apart from screen center's point of content slidably).Therefore, this Detail View 42 that scrolling view operation and locating module 36 stop for sliding is readjusted by a small margin position to till showing complete " five grades of Pan Kou " details, and the screen-picture after adjustment is as shown in Fig. 7 C.
Fig. 2 B of Fig. 7 B of the embodiment of the present invention two and Fig. 7 C and existing two is done to one relatively, can find that the two ends, left and right of existing Detail View 18 all show Incomplete information (as shown in Figure 2 B) after slip stops when user is with the power (being the speed of sliding speed) of same slide.And Detail View 42 of the present invention is after slip stops, on screen, only of short duration demonstration is as the picture of Fig. 7 B, and and then scrolling view operation and locating module 36 readjust by a small margin the nearest best image position of scrolling view to complete location (as shown in Fig. 7 C).The picture occurring in succession with the next 7B with the aid of pictures of user's naked eyes and Fig. 7 C, in the middle of being difficult for discovering, user has the extremely of short duration best image position that stops being adjusted at once, therefore, user's slide scrolling view of the present invention does not need to make another skillful opening and slides to do the fine tune of position.
So-called " nearest best image position " can be via detecting and calculating following project and learn: " slidably the displayable overall width of its screen of content (that is, the first overall width) ", " screen instantly slidably content presented multiple contents of complete information overall width (that is, the second overall width) ", " available breadth extreme " (being front two remainders after subtracting each other), " two ends, left and right slidably the content person that presents in Incomplete information its respectively need width (that is, left end content width, right-hand member content width) ", and " two ends, left and right are content (left end content slidably, right-hand member content) the person's whichever that presents in Incomplete information apart from the screen center point of content slidably closely (that is, calculate left end distance and right-hand member distance) ".Above-mentioned " content " mentioned refers to one " field " in quotation information view 40, refers to one " details " in Detail View 42.Illustrate as an example of the quotation information view 40 of Fig. 6 B example, if " the slidably displayable overall width of its screen of content " (excluding fixing " title " field) of quotation information view 40 is " 1300 " individual pixel (Pixel), and " screen instantly slidably content presented the overall width of multiple contents of complete information " (counted from " conclusion of the business " field, till " receipts yesterday " field, one connects the overall width of nine fields) be " 1050 " individual pixel, these two are subtracted each other i.e. " available breadth extreme " is to be " 250 " pixel.Suppose high order end " selling " field that slidably content presents Incomplete information and low order end slidably content present identical " 130 " individual pixel that all needs of its width of " amplitude " field of Incomplete information.Due to " available breadth extreme " be all greater than (>) both, therefore, both are last, and than seeing whichever distance, slidably screen center's point of content is nearer again, finally readjust by a small margin scrolling view position with show this distance slidably the nearlyer person's of screen center's point of content result calculate a best image position.
Separately having a kind of situation is that high order end Incomplete information " sells " that field is different from its width of low order end Incomplete information " amplitude " field and difference is very large, suppose that its width of " selling " field need account for " 260 " individual pixel, and its width of " amplitude " field only accounts for " 130 " individual pixel, because " available breadth extreme " only can hold " amplitude " field.Therefore, this kind of situation do not need whichever distance relatively again, and slidably screen center's point of content is nearer, and directly readjust by a small margin scrolling view position to show this open ended information completely, that is " amplitude " field, this is " the nearest best image position " of this situation.That is, the calculating benchmark using complete display width smaller as nearest best image position.
With regard to another embodiment, in the time that available breadth extreme is greater than left end content width and right-hand member content width, can complete demonstration left end content to calculate nearest best image position, or, with complete demonstration right-hand member content to calculate this nearest best image position.
