Existing technical scheme comprises: XML Organization of Data form, JSON Organization of Data form.
For XML Organization of Data form (Extensible Markup Language), being used for the electroactive marker son file makes it have structural markup language, can be used for flag data, definition data type, the source language that to be a kind of user of permission define oneself markup language.Be used for the electroactive marker son file and make it have structural markup language, can be used for flag data, definition data type, the source language that to be a kind of user of permission define oneself markup language.The shortcoming of this scheme is: adopt XML Organization of Data data to carry out the conversion of form to the data that gather, greatly postponed from the time of data to data tissue, also to increase the implication that corresponding label represents current data to data, can cause the mass data redundancy to small data quantity, just become chicken ribs at the more simple Organization of Data of reply.The collection of having adopted in the present invention data is namely the generated data form.Be to resolve or SAX resolves the traversal that has related to label with DOM in parsing, reduced efficient.
For JSON Organization of Data form (JavaScript Object Notation), it is a kind of data interchange format of lightweight.It is based on the subset of JavaScript (Standard ECMA-2623rd Edition-December1999).JSON adopts the text formatting that is totally independent of language, but has also used the custom that is similar to the C family of language.These characteristics make JSON become desirable exchanges data language.Be easy to the people and read and write, also be easy to machine simultaneously and resolve and generate.The shortcoming of this scheme is: remove to resolve JSON if be unfamiliar with the structure of JSON, that is bad dream only not.Waste time and energy and do not say, the code redundancy that also can become is dilatory, and the result that obtains is also unsatisfactory.Identical message section in the JSON context mixes each other, and due to JSON approval colon assignment, and who should be taken as text to be difficult to differentiation between practical property value.In addition, the foundation of JSON segment and self-criticism process aobvious mixing slightly.
Summary of the invention
The present invention proposes a kind of tissue and analytic method of Android screen contact track data, solved in the track data reproduction capability of Sharing Whiteboard under the Android platform and shared drawing pad because the problem of the inefficiency that tissue transmission and resolution data cause has made up weak point of the prior art.
Technical scheme of the present invention is achieved in that
A kind of tissue and analytic method of Android screen contact track data comprise the following steps:
1) get the x of tracing point, after the y coordinate in the mode of assembly unit character string as down:123:456 or move:123:456 or up:123:456;
2) the good character string of assembly unit being broken into packet uses procotol to send;
3) accepting device receives and is divided into three segment datas according to following rule after data, first paragraph representative action, and second segment and the 3rd section are converted into the digitized representation coordinate, then carry out track in the demonstration of screen.
Tissue and the analytic method of described Android screen contact track data, the action of screen contact track is divided into three kinds: press, move and lift; Action is pressed in the down representative; Move represents shift action; Action is lifted in the up representative.
Beneficial effect of the present invention is: the contact track data that will transmit and reappear for the Android screen, realized efficiently organizing fast transmission and parsing and minimizing redundant data, can be used for the synchronous instant playbacks of track data on other Android equipment such as Android drawing pad.Eliminate the obvious time-delay sense of prior art.
