Fig. 1 for preferred embodiment of the present invention provide a kind of for eliminating the process flow diagram of method of page shake;
Fig. 2 for preferred embodiment of the present invention provide a kind of for eliminating the block diagram of device of page shake.
Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described in further detail.
Fig. 1 for the present invention's the first preferred embodiment provide a kind of for eliminating the process flow diagram of method of page shake.The method is applicable to mobile terminal, comprises the following steps:
S100: default multiple templates that load and show for content.
S200: reading out data.
S300: select successively corresponding template according to the content of each data, by data and list box control binding, generate list box.
S400: in the time of the initial demonstration of the page or page rolling, choose the data that need demonstration in list box, the data that needs are shown are loaded in internal memory, generate user interface element.
S500: show user interface element.
Among the present embodiment, among step S200, the data that read can be the local file of mobile terminal or information of obtaining by network etc.The choosing of step S400 needs the data that show in list box, be the data of choosing in list box visual range, chooses in other words the data that need be presented in the user visual field.Can certainly select in the lump with list box visual range in the adjacent data of data, in other words, be presented at need the data that data in the user visual field are adjacent and be loaded in internal memory.By only the data of selection being loaded in internal memory, can reduce memory cost.
In addition, the method further comprises shift the focus, further to reduce the shake of the page.The operation of shift the focus, specifically comprises: monitor the rolling of list box, in the time that the page rolls, will show the element of focal point settings outside list box; In the time that page rolling stops, showing that focal point settings is in list box.
Further, in the time that the page rolls, can judge whether the data in internal memory need to show, if be judged as NO, these data be removed from internal memory.Like this, for the content of the list box of having shown, if not list box show visual range in (in other words, user not within sweep of the eye) from internal memory, remove.Can reduce the expense of internal memory, the running quality of maintenance system.
Further, the present embodiment can arrange cache mode, particularly, and can be by cache mode (CacheMode) parameter of virtual stack panel (VSP, Virtualizing Stack Panel) be set.Comprise: judge the display mode of data, if the display mode of data is the display mode of acquiescence, cache mode is set to acquiescence (Standard) pattern; If the display mode of data is the display mode of circulation, cache mode is set to circulation (Recycling) pattern, and system can reclaim the content of producing and showed, ensures the content that enough memory headrooms are shown needs.Can cache mode be set according to the difference of display mode like this, improve treatment effeciency.
Fig. 2 for the present invention's the first preferred embodiment provide a kind of for eliminating the block diagram of device of page shake.This device is applicable to mobile terminal, comprising: presetting module 100, data read module 200, list box generation module 300, data load-on module 400 and display module 500.
Presetting module 100, for default multiple templates that load and show for content.
Data read module 200, for reading out data.
List box generation module 300, for selecting successively corresponding template according to the content of each data, by data and list box control binding, generates list box.
Data load-on module 400, in the time of the initial demonstration of the page or page rolling, chooses the data that need demonstration in list box, and the data that needs are shown are loaded in internal memory, generate user interface element.
Display module 500, for showing user interface element.
Data load-on module 400 among the present embodiment, specifically for choosing the data in list box visual range, the data in the user visual field, are loaded in internal memory in other words, generate user interface (UI) element.Can certainly select in the lump with list box visual range in the adjacent data of data, in other words, the data adjacent with data in the user visual field are loaded in internal memory.
Among the present embodiment, this device also comprises focal point settings module 600, can shift the focus, and further to reduce the shake of the page.Focal point settings module 600, for monitoring the rolling of list box, in the time that the page rolls, will show the element of focal point settings outside list box; In the time that page rolling stops, showing that focal point settings is in list box.
Further, when the page is initial when showing or rolling, data load-on module 400 can judge whether the data in internal memory need to show, in the time judging that data in internal memory do not need to show, these data is removed from internal memory.Like this, for the content of having shown, if not show visual range in (in other words, user not within sweep of the eye) from internal memory, remove.Can reduce the expense of internal memory, the running quality of maintenance system.
This device further comprises buffer setting module 700, for judging the display mode of data, thereby virtual stack panel (VSP is set, Virtualizing Stack Panel) cache mode (CacheMode), if the display mode of data is the display mode of acquiescence, cache mode is set to default mode; If the display mode of data is the display mode of circulation, cache mode is set to circulation pattern, and system can reclaim the content of producing and showed, ensures the content that enough memory headrooms are shown needs.
With WindowsPhone platform, especially, carrying out exemplary explanation as an example of WindowsPhone7 platform example below, is only application examples more of the present invention.
Due to the form difference of the content that will show in list box, can preset different templates, giving in the process of list assignment, need to be filled into each the content of list, increase an attribute, it is template attribute, illustrate and need to select any template to show, be used to provide to list, show by that template with selection, for example template A exhibiting pictures content, template B shows word content, need to be in generating the data of list box (listbox), be use template A by template setup of attribute corresponding word content, the template setup of attribute that image content is corresponding is use template B, ListTemplate Selector class is according to the template attribute arranging, select template.
In the time that list stops by focus to scroll bar, can know that scroll bar is in rolling or halted state by catching scroll bar state in ListBox.When scroll bar is during in rolling condition, give scroll bar page focus, now can prevent that all the other elements from obtaining focuses and affecting the calculating of list element height.In the time that scroll bar stops, focus is given back to current page:
Embodiments of the invention have advantages of following:
(1) by using default template to load corresponding data content, by data and list box control binding, generate list box, thereby can in the time showing, not shake because of Asynchronous loading;
(2) by shift the focus, further reduce the shake of the page;
(3) by will not needing to show that data remove from internal memory, can reduce the expense of internal memory, the running quality of maintenance system;
(4) by according to the difference of acquiescence display mode, circulation display mode, cache mode is set, can improves treatment effeciency.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, any be familiar with those skilled in the art the present invention disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
