Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the related invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 is a schematic flowchart of a method for implementing continuous display of large-scale data for an android system according to an embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:
a) creating a container class CommonListView on an android system on which the touch device operates, and monitoring scrolling of the set container class CommonListView;
b) when monitoring that the container type CommonListView is scrolled to the top or the bottom, triggering an internal process to asynchronously load data to be browsed;
c) and after the loading is completed, informing a container class CommonListView for displaying data and an adapter class CommonAdap for displaying a view to update the data and the interface displayed by the touch device.
In a preferred embodiment, said step a) is monitoring the change of the scroll status of said container class commonlistiew by onScrollStateChanged in class OnScrollListener for monitoring.
The inventors have found that the scrolling of CommonListView can be monitored by the OnScrollListener, where:
(1) the sequence number of the first displayed item, the number of the displayed items and the total number of the items can be obtained through onScrollListener in the OnScrollListener.
(2) The change of the rolling state can be monitored through onScrollStateChanged in the OnScrollListener, and the rolling state can be known to be the topmost or the bottommost by acquiring the state in the onScrollListener, so that the loading and the swapping out of the data signals are triggered in the two states.
In a preferred embodiment, the method further comprises the step of instantiating a commonlinkedlst class for saving data and a larelinked list subclass inherited to the commonlinkedlst class for enabling switching and loading of data.
In a preferred embodiment, in said step b), when the scrolling to the top is detected, an instruction of loading data to be displayed backwards in the subclass LargeLinkedList is triggered; and when detecting that the scroll is to the bottom, triggering an instruction of loading the data to be displayed forward in the subclass larelinkedlst.
Fig. 2 shows a schematic diagram of an implementation method according to a specific embodiment of the present invention. As shown in FIG. 2, a CommonListView class is first created and then a CommonAdap class and a LargeLinkedList subclass are instantiated. And monitoring sliding of the CommonListView class to detect whether the rolling window is at the top or the bottom. Triggering a LoadData (BACKWARD _ LOAD, mVisibleitemCount) method in the LargeLinkedList to LOAD data when the top is detected; when the bottom is detected, a loadData (FORWARD-LOAD, mVisibleitemCount) method in the LargeLinkedList is triggered to LOAD data. When data is loaded, an internal LoadDataThread thread is triggered to asynchronously record the data. After the loading is complete, the classes CommonAdap and CommonListView are notified to update the displayed data and interfaces.
The CommonAdap subclass implementing BaseAdap is used to cooperate with the ListView display view. The specific implementation is shown in fig. 3.
The subclass LargeLinkedList is mainly used for storing data and implementing operations such as data addition, deletion, and acquisition, and the specific implementation thereof is shown in fig. 4.
The subclass larelinkedlst for implementing switching and loading of data inherits to the class commonlinkedlst, and its specific implementation is shown in fig. 5.
In a preferred embodiment, the method further includes including an instruction to set a maximum single load space in the subclass largelinkedlst to achieve a minimum footprint for the memory.
In a preferred embodiment, the method further includes creating a plurality of display sub-controls and a corresponding plurality of display data units simultaneously, where the plurality of display sub-controls occupy 3 times of the space of the display interface of the touch device; and in the event that the touch device switches from displaying a first 1/3 portion of the plurality of display subspaces to displaying a second 1/3 portion of the plurality of display subspaces during interface scrolling, asynchronously loading display data of a subsequent 1/3 portion to be displayed in the triggered loading to replace data of a display data unit corresponding to the first 1/3 portion. It is worth noting that this is one of the important points of the present application.
The inventor believes that to display a large amount of data requires, first, enough interface controls to display the data and, second, enough memory to store the data. However, those skilled in the art know that relatively large data, regardless of how large the memory is, is never sufficient. Based on these problems, the inventor carefully analyzes its application scenario and finds that it does not need to display these data at the same time, so that the display sub-controls can be multiplexed by adopting a time-to-space technique. Assuming that we want the display area to display only 20 cell sub-items, we can prepare 60 display cells and 60 data storage cells in order to make their switching smoother. When the first display, we create 60 display units and preload 60 unit sub-items (i.e., data storage units) from the storage medium, when 1-20 units out of the 60 display units are displayed, no operation is required since both data and display units are already present. When the display area is changed to 2/3 of 60 display units, i.e. the display area is changed to 30-40 display units, we have 20 display units and corresponding data storage units. However, in order to make the view switching more gradual, we need to load the following data and abandon the data of the aforementioned 1-20 units, and at the same time, make the dynamic transfer of the former 20 display areas to the following data for displaying. Therefore, the data to be displayed and the display unit are prepared, when the display reaches the next display period, all the data are prepared, and the data are simply displayed, so that the aim of displaying the large data in the small memory is fulfilled through the repeated actions.
The method provided by the invention can realize the technical effect of displaying infinite data by using a small memory on the touch equipment, solves the problem of data display on the small memory equipment, reduces the equipment cost and can generate good economic effect. With the development of society, more and more embedded devices and mobile devices are provided, global devices are increased at a speed of hundred million, each device can save cost of some memories, and finally the generated economic benefit is considerable.
While the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
