Between carry out data communication, methods described comprises the following steps：
Step 1, data object corresponding to the document that android terminal will need online preview is sent to server；
Step 2, the data object that server is sent to android terminal parses, and obtains the unique mark of document, passes through
Data base querying obtains corresponding document, converts the document into PDF format；
Step 3, what the server address write service device where server is converted into the document after PDF format received
In data object, amended data object is then forwarded to android terminal；
Step 4, the data object that android terminal the reception server returns, where parsing to obtain PDF format document to it
Server address；
Step 5, document is obtained in the server address where the document that android terminal is analytically obtained by Java technology
Binary stream, show the PDF binary streams using the view plug-ins of increasing income that PDF format can be read, complete the display of document.
In above-mentioned steps 1, data object corresponding to document includes following parameter：name:Document name；url:Taken where document
The address of business device；And uuid：The exclusive identification code of the document；In step 2, after server parses to data object,
Obtain parameter name, url and uuid.
In above-mentioned steps 5, android terminal passes through URL, InputStreamReader or the BufferedReader in Java
Technology obtains the binary stream of document from server address.
In above-mentioned steps 5, the view plug-ins of increasing income that PDF format can be read refer to com.github.barteksc:
android-pdf-viewer。
A kind of system for realizing document in online preview server in Android device, including android terminal and server；
Server includes：
Receiving module, for receive android terminal transmission the online preview request of document and online preview document corresponding to number
According to object；
Transcoding module, for according to obtained unique mark in parsing received data object, by corresponding to unique mark
Document is converted to PDF format；And
First sending module, for by the document related data parameter read-in data object after conversion and being sent to peace
Tall and erect terminal, the data object include the server address where document after conversion；
Android terminal includes：
Second sending module, for sending the online preview request of document to server, the request is included corresponding to document
Data object；
Terminal receiving module is used to receive the document data object after the conversion of the server return；And
Display module, the view plug-ins of increasing income that PDF format can be read are integrated with, for showing by Java technology analytically
The binary stream of document is obtained in server address where obtained document.
After such scheme, preview document is converted to PDF format by the present invention, is read for Android device, using PDF across
Platform, it is safe, be not easy to change, read the characteristics of performance is high, reading comfort is good, compared to the document of word forms, PDF texts
Part form is more formal.
Brief description of the drawings
Fig. 1 is the integrated stand composition of the present invention；
Fig. 2 is the flow chart of the present invention.
Embodiment
Below with reference to accompanying drawing, technical scheme and beneficial effect are described in detail.
The present invention provides a kind of method for realizing document in online preview server in Android device, when realizing, first
Ensure that server can be communicated successfully with android terminal, the two can mutually Phase Receiver and transmission data, and now android terminal
Have shown that a series of document obtained from server；Server and android terminal arrange a known data object, false
The entitled Document of the fixed object, concurrently sets and following parameter is included in Document objects：name:Document name；url:Document
The address of place server；uuid：The exclusive identification code of the document.Coordinate shown in Fig. 2, methods described comprises the following steps：
Step 1, all documents shown in android terminal have a data object Document, by each object institute
The memory address of mapping is all different, therefore each document has oneself corresponding data object, when user clicks on
When needing to carry out the document of online preview in android terminal, android terminal sends data object Document corresponding to the document
To server；
Step 2, server receives the data object Document of android terminal transmission, to data object Document
Parsed, obtain the unique mark of document：Parameter name, url and uuid, received data pair is obtained by data base querying
As corresponding document, server converts the document into PDF format again；
Step 3, what the server address write service device where server is converted into the document after PDF format received
In data object Document url parameters, the data object Document after renewal is then forwarded to android terminal；
Step 4, the data object Document that android terminal the reception server returns, parses to obtain parameter url institutes to it
Server address where the document of expression；
Step 5, android terminal passes through the technologies such as the URL in Java, InputStreamReader, BufferedReader
The binary stream of document is obtained in server address where the document analytically obtained, using increasing income for PDF format can be read
View plug-ins show the PDF binary streams, complete the display of document.
Wherein, the PDF being mentioned above, is a kind of document format of Adobe companies exploitation, and Adobe companies have completely to PDF
Copyright, therefore the primary document for not supporting to read PDF format of Android system of Google exploitations is, it is necessary to non-Google officials Android
Application developer voluntarily writes the view plug-ins that PDF format can be read, and the android terminal being related in the present invention, is integrated with readable
Take the view plug-ins com.github.barteksc that increases income of PDF format:android-pdf-viewer.
The present invention also provides a kind of system for realizing document in online preview server in Android device, including android terminal
And server, as shown in figure 1, server includes receiving module, transcoding module and the first sending module, the receiving module is used for
Data object corresponding to the online preview request of document and online preview document that reception android terminal is sent；The transcoding module is used
According to the unique mark obtained in parsing received data object, document corresponding to unique mark is converted into PDF format；Institute
The first sending module is stated to be used for the document related data parameter read-in data object after conversion and be sent to android terminal,
The data object includes the information such as the server address where document after conversion；Android terminal includes the second sending module, terminal
Receiving module and display module, wherein, second sending module is used to send the online preview request of document to server, described
Request includes data object corresponding to document；The terminal receiving module is used for after receiving the conversion that the server returns
Document data object；The display module is integrated with the view plug-ins of increasing income that PDF format can be read
com.github.barteksc:Android-pdf-viewer terminal display module, pass through Java technology from solution for showing
The binary stream of document is obtained in the address of server where analysing obtained document.
The technological thought of above example only to illustrate the invention, it is impossible to protection scope of the present invention is limited with this, it is every
According to technological thought proposed by the present invention, any change done on the basis of technical scheme, the scope of the present invention is each fallen within
