The purpose of the present invention is to solve the problems existing in the prior art and provide a method and computing device for displaying multiple files of different formats on one page. The specific scheme is as follows:

[0005] A method for displaying multiple files in different formats on one page, comprising: configuring a Service service and an AIDL service in an Android system program, wherein the Service service supports office software running on the Android system, and the AIDL service supports cross-process communication between the office software and the Android system; running the office software, the main process of the office software obtains document data of multiple target files from the Android system, opens multiple target files, the main process calls the Service service to generate multiple sub-processes that support the operation of the multiple target files; the sub-process obtains document data from the main process, parses and typesets the document data to obtain a parsed data packet, the sub-process calls the AIDL service to send the parsed data packet to the main process, and the main process displays the parsed data packet.

[0006] Furthermore, in the above technical solution, the main process of the office software obtains the document data of multiple target files from the Android system by calling the AIDL service, and calls the recyclerview control to display the obtained document data to the user.

[0007] Furthermore, a plurality of the target files are opened, and the main process of the office software calls the Service service to generate a plurality of sub-processes supporting the running of the plurality of the target files, wherein one target file corresponds to one sub-process.

[0010] Furthermore, after the sub-process parses and typesets the document data to obtain a parsed data packet, the sub-process sends a signal to the main process through the AIDL service. After the main process receives the signal, the main process uses a view tool to draw the received parsed data packet to obtain the document content of the target file. The main process displays the drawn document content on the interface of the office software.

[0011] The present invention also provides a computing device, which includes an Android system, wherein an AndroidManifest configuration file of the Android system is configured with a Service service and an AIDL service, an application of office software is implanted in the Android system, one or more target files are opened with the office software, and one or more target files are displayed on an interface of the office software.

[0012] The above technical solution further includes opening one or more target files with the office software, and displaying one or more target files on the interface of the office software. The specific implementation steps include:

[0013] The office software runs on the Android system with the support of the Service.

[0014] Open multiple target files on the Android system, and the main process of the office software obtains document data of the multiple target files through the AIDL service.

[0015] The main process creates multiple sub-processes corresponding to the multiple target files one by one through the Service service.

[0016] The sub-process obtains the document data of the target file corresponding to the main process through the AIDL service, and parses and typesets the obtained document data to obtain a parsed data packet.

[0017] The sub-process sends the parsed data packet to the main process through the AIDL service, and the main process draws the parsed data packet and displays the drawn document content on the interface of the office software.

[0018] Compared with the prior art, the method and computing device for displaying multiple files in different formats on one page provided by the present invention can realize the simultaneous display and operation of multiple documents in different formats on one page of office software without switching back and forth for viewing.

[0027] The gist of the present invention is further explained below with reference to the accompanying drawings and embodiments.

[0028] Example:

[0029] Existing office software cannot display and operate multiple files of different formats on one page at the same time. Such switching back and forth increases the workload, wastes time and is inconvenient. The purpose of the present invention is to solve the problems existing in the prior art and provide a method and computing device for displaying multiple files of different formats on one page. Figure 1-3 .

[0030] In one aspect, the present invention provides a method for displaying multiple files of different formats on one page, see Figure 1-3, which includes: configuring a Service service 11 and an AIDL service 12 in a program of an Android system 10, wherein the Service service 11 supports office software running on the Android system 10, and the AIDL service 12 supports cross-process communication between office software and the Android system 10; running office software, a main process 20 of the office software obtains document data of multiple target files from the Android system 10, opens multiple target files, and the main process 20 calls the Service service 11 to generate multiple sub-processes that support the running of the multiple target files; the sub-process obtains document data from the main process 20, and parses and typesets the document data to obtain a parsed data packet, the sub-process calls the AIDL service 12 to send the parsed data packet to the main process 20, and the main process 20 displays the parsed data packet.

[0031] In one embodiment, see Figure 1 The main process 20 of the office software obtains the document data of multiple target files from the Android system 10 by calling the AIDL service 12, and calls the recyclerview control to display the obtained document data to the user.

[0032] In one embodiment, see Figure 2 , opening multiple target files, the main process 20 of the office software calls the Service service 11 to generate multiple sub-processes that support the running of the multiple target files, wherein one target file corresponds to one sub-process.

[0033] In one embodiment, the formats of the plurality of target files include one or more of doc format, docx format, xls format, xlsx format, ppt format, pptx format, txt format and pdf format.

[0034] In one embodiment, the child process calls the AIDL service 12 to obtain document data from the main process 20, where the document data includes a document path and a document name.

[0035] In one embodiment, see Figure 3 After the sub-process parses and typesets the document data to obtain a parsed data packet, the sub-process sends a signal to the main process 20 through the AIDL service 12. After the main process 20 receives the signal, the main process 20 uses a view tool to draw the received parsed data packet to obtain the document content of the target file. The main process 20 displays the drawn document content on the interface of the office software.

[0036] The present invention also provides a computing device, which includes an Android system 10, wherein the AndroidManifest configuration file of the Android system 10 is configured with a Service service 11 and an AIDL service 12, and an application of office software is implanted in the Android system 10, and one or more target files are opened with the office software, and one or more target files are displayed on the interface of the office software.

[0037] The above technical solution further includes opening one or more target files with the office software, and displaying one or more target files on the interface of the office software. The specific implementation steps include:

[0038] The office software runs on the Android system 10 with the support of the Service 11.

[0039] Open multiple target files on the Android system 10, and the main process 20 of the office software obtains the document data of the multiple target files through the AIDL service 12,

[0040] The main process 20 creates multiple sub-processes corresponding to the multiple target files one by one through the Service service 11.

[0041] The sub-process obtains the document data of the target file corresponding to it from the main process 20 through the AIDL service 12, and parses and typesets the obtained document data to obtain a parsed data packet.

[0042] The sub-process sends the parsed data packet to the main process 20 through the AIDL service 12, and the main process 20 draws the parsed data packet and displays the drawn document content on the interface of the office software.

[0043] Compared with the prior art, the method and computing device for displaying multiple files in different formats on one page provided by the present invention can realize the simultaneous display and operation of multiple documents in different formats on one page of office software without switching back and forth for viewing. All documents displayed on the same page support separate operation, and all internal operations do not affect other documents. In addition, doc format, docx format, xls format, xlsx format, ppt format, pptx format, txt format and pdf format can all be displayed on one page at the same time, and also support separate operation without affecting each other.

[0044] The general implementation principle of the method for displaying multiple files of different formats on one page provided by the present invention is as follows: the office software supports the display and operation of multiple documents on one page by using the Android Service 11 to open a new process and perform cross-process communication through AIDL. That is, when opening a document, the program adds a new document process by binding the Service 11, and then uses AIDL to pass the data required by the document process through the main process 20. After receiving the data, the document starts the document parsing operation, and after the parsing is completed, the main process 20 is notified to display it.

[0045] In order to realize the simultaneous operation of multiple documents, it is necessary to open multiple processes to manage multiple documents. The main process 20 is equivalent to the administrator, who issues orders to the documents that need to be operated. Figure 2 .

[0046] When multiple documents are displayed on the same page by the method of displaying multiple files of different formats on one page described in the present invention, the relevant Service service 11 and AIDL related configurations must be configured in the AndroidManifest configuration file of Android. It should be noted here that if the Service service 11 is needed, the Service related information must be configured in the AndroidManifest configuration file. This is a necessary operation for Android to use the Service service 11, while the use of the AIDL service 12 does not need to be configured in the AndroidManifest configuration file. It has its own usage process, which involves the usage of basic knowledge of Android. The configuration here is equivalent to laying the foundation for realizing this function.

[0047] When the office software program is opened, the main process 20 of the office software will obtain the document data in the Android device, display the data through the recyclerview control, open the target file, and the main process 20 will be bound to the Service service 11 in the configuration file to open a child process (i.e., document process), named here as child process 1. Child process 1 and main process 20 are two processes that have nothing to do with each other. Then the main process 20 and child process 1 will communicate across processes through the AIDL service 12 (the main process 20 and the child process belong to two different processes, and processes generally cannot directly exchange data. The AIDL service 12 can solve the problem of data exchange between the two processes. The communication here can be regarded as data transmission, and the cross-process communication here is only communication between processes). The document-related data that the main process 20 can obtain (the document data is not the content of the document itself, but the basic information of the document, such as the document path) is passed to the child process 1. After receiving this information, the child process 1 performs content parsing and typeset on the document to be opened through internal parsing steps.

[0048] When child process 1 finishes parsing and typesetting the document, it sends a signal to the main process through AIDL. After receiving the signal, the main process notifies the view of the main process to draw the document content, so that the document content is displayed on the interface. After the parsing is completed, the parsed data packet is used by the main process to complete the page drawing. Correspondingly, when the corresponding changes are made, they must also be passed to the child process through the main process, and then the child process will update the data.

[0049] It should also be noted that opening multiple documents of different formats at the same time is also handled according to the above process. Since they are different processes, the operations of multiple documents will only be processed in their own processes and will not affect other documents. When opening multiple files, the main process will generate multiple window views, and these windows will correspond to these documents one by one. Since the content size of each document is different, the time for the sub-process to complete the parsing is not fixed, so the timing of the document content appearing in the view window is also not fixed. The document opened first may be slower than the content of the file opened later due to the long parsing time, so there will be a sequence of page display. Due to the existence of the view window, it does not affect the browsing of the document.

[0050] In summary, the method and computing device for displaying multiple files in different formats on one page provided by the present invention can realize the simultaneous display and operation of multiple documents in different formats on one page of office software without switching back and forth for viewing. All documents displayed on the same page support independent operation, and all internal operations do not affect other documents.
