The smart terminal 101 may be any device capable of implementing smart input and output, for example, a mobile terminal, such as a mobile phone, a tablet computer, etc.; other devices having the above-described structure are also possible.
A flowchart of a method for displaying files on a smart terminal in one embodiment is shown in fig. 3. As shown in fig. 3, the method in this embodiment includes the steps of:
step S301: the file content of the file to be displayed is acquired,
step S302: analyzing the file content to obtain each content structure of the file content;
step S303: converting each content structure into webpage content;
step S304: and displaying the webpage content obtained after conversion through webpage browsing software.
According to the scheme of the embodiment of the invention, when the file to be displayed of the intelligent terminal is displayed, the file content of the file to be displayed is obtained and then analyzed to obtain the content structure of the file content, the content structure is converted into the webpage content, and then the webpage content is displayed through the webpage browsing software, so that various bottom interfaces of the system are not needed to be used, the bottom interfaces are not needed to be packaged, the webpage content is converted into the webpage content, and the webpage is displayed by means of the webpage browsing software technology for typesetting, rendering and displaying, so that the whole rendering and displaying process is simplified, the file can be displayed on the intelligent terminal in a simplified manner, and the displaying efficiency is high.
After the file content of the file to be displayed is obtained in step S301, the file content may be loaded into the local memory for storage and then analyzed. Accordingly, fig. 4 is a flowchart illustrating a method for displaying a file on a smart terminal according to another embodiment of the method. As shown in fig. 4, the method in this embodiment includes the steps of:
step S401: the file content of the file to be displayed is acquired,
step S402: loading the acquired file content to a local memory;
step S403: analyzing the file content loaded to the local memory to obtain each content structure of the file content;
step S404: converting each content structure into webpage content;
step S404: and displaying the webpage content obtained after conversion through webpage browsing software.
Therefore, after the file content is obtained, the file content is loaded into the local memory, and then the file content loaded into the local memory is analyzed, so that the continuity and the fluency of the analysis and display processes can be ensured.
It can be understood by those skilled in the art that, in addition to loading the file content into the memory, other manners may also be used to process the file content, and accordingly, the continuity of parsing and displaying is ensured.
When the file content is parsed in the above steps S302 and S403, the specific parsing process may be performed locally in the smart terminal in general, and may also be performed by a third-party device other than the smart terminal, for example, a server, based on actual needs.
On the other hand, in the data stream of the file content, for different file formats in the file content, some specified fields in the related data stream may include information of the file format, and corresponding other related fields may include specific content information of the file format, so that it may be clear to a person skilled in the art that, when parsing the file content, various file formats and related specific contents included in the file content may be determined by analyzing bytes of the related fields based on the difference of the file formats, and this analysis and parsing process may be performed in any possible manner that exists at present and may appear later, and therefore, the parsing process is not repeated.
After the analysis, a content structure of the file content is obtained, where the content structure may specifically include a content type and attribute data corresponding to the content type. The content types may be many, such as pictures, tables, text, graphics, icons, formulas, symbols, audio, video, etc., but may be other content types not listed here. The content types of the content of the file may vary from file to file, and are typically one or more of various content types, as well as various combinations of these content types.
HTML (HyperText Markup Language) is a Markup Language for designing and creating web pages and other information that can be viewed in web browsing software, and its documents are not complicated to make, but powerful, and support the embedding of files in different data formats. Accordingly, in one specific example, the web page content may be HTML content. In addition, because the CSS is a style design language that can truly separate web page representation from content, compared with the representation of the conventional HTML, the CSS can perform pixel-level precise control on the position layout of objects in a web page, support almost all font and font styles, have the capability of editing web page objects and model styles, and can perform preliminary interactive design, and thus, the web page content can also be HTML CSS content. The web page browsing software may be a web page browser in general, and those skilled in the art understand that the web page browsing software may also be other software for browsing a web page as long as the browsing of an HTML web page can be implemented.
In this case, taking the web content as HTML content as an example, when each content structure is converted into the web content in the above steps S303 and S404, the following method may be adopted:
adding a label of an HTML language corresponding to each content type according to the content type contained in each content structure;
and respectively setting the attribute content of each label corresponding to each content type according to the attribute data corresponding to each content type, and obtaining the converted HTML content.
In the HTML language, different labels are configured aiming at different content types, so that the labels corresponding to the related content types in the HTML language are added based on the difference of the content types, and the attribute contents related to the labels in the HTML contents are set based on the related attribute data of the content types, so that the conversion from a content structure to the HTML contents can be conveniently realized, various bottom interfaces of a system are not needed to be used, the bottom interfaces are not needed to be packaged, and the HTML technology is used for typesetting, rendering and displaying, so that the whole rendering and displaying process is simplified.
The following is exemplified in detail with reference to the embodiment in fig. 4, and with reference to a specific process for displaying a file on an intelligent terminal.
When the file to be displayed needs to be displayed, the file to be displayed may be a file stored in the intelligent terminal locally in advance, or may be a file obtained from a server, the file content of the file to be displayed is obtained first, then the obtained file content is loaded into a memory for local analysis, and the analysis process can be performed in any possible way existing at present and possibly appearing in the future, so that the content structure of the analyzed file content is obtained. The content structure specifically includes a content type and attribute data corresponding to the content type.
The content types of the content of the files may vary from file to file, and may be any one or any combination of pictures, tables, text, graphics, icons, formulas, symbols, audio, video, and other various content types not listed.
For different content types, the corresponding attribute data can be used to assist rendering display, and for various content types and the corresponding attribute data contained in the file, the content types and the corresponding attribute data are converted into corresponding web page contents one by one. In view of the fact that HTML is a markup language for designing and creating web pages and other information visible in web browsing software, documents are not complex to make and are powerful, and support the embedding of files of different data formats, and therefore, in the embodiment of the present invention, the web content may be HTML content. In addition, because the CSS is a style design language that can truly separate web page representation from content, compared with the representation of the conventional HTML, the CSS can perform pixel-level precise control on the position layout of objects in a web page, support almost all font and font styles, have the capability of editing web page objects and model styles, and can perform preliminary interactive design, and thus, the web page content can also be HTML CSS content. Then, the HTML content or the HTML CSS content obtained by conversion can be typeset, rendered and displayed by adopting an HTML technology or a CSS technology.
The following will exemplify the way of converting the content of several files into HTML content, taking the content types of the file contents as examples.
Taking the content type as an example, the HTML has a tag img for displaying the picture, and after the file content is analyzed to obtain the picture, the analyzed picture can be stored locally in the intelligent terminal, and a picture storage path for storing the picture is recorded. And then adding an img tag in the HTML content, and setting the src attribute of the img tag as the picture storage path, thereby realizing conversion to the HTML content. For example, by setting the src attribute of the img tag, that is, < img src ═ picture storage path "/>, the conversion from a picture to HTML content can be completed without calling a system bottom interface or packaging the system bottom interface, which is very simple.
On the other hand, for pictures there may be other attribute data, such as a centered display picture. At this time, when the attribute data corresponding to the picture includes the center display picture, the conversion of the attribute data of the center display picture into the HTML content can be realized by setting the style attribute of the div tag to text-align: center. At this time, for a picture with a centered display attribute, as long as < div style ═ text-align: center is set; and if the 'img src ═ is the mobile phone path where the picture is located'/>/</div >, the picture with the centered display attribute is converted into the HTML content, and the picture is displayed in the center.
Taking the content type as an example of a table, a table tag in the HTML is used for displaying the table, and the table in the document can be easily converted into a < table > tag of the HTML, and a specific example manner may be: adding a table tag in HTML content; adding corresponding tr labels for each row of the table respectively; adding td labels and/td labels respectively corresponding to the cells after tr labels corresponding to the rows according to the number of the cells of each row of the table; and adding the text content of each cell between the td label and/td label corresponding to the cell.
Of course, those skilled in the art will understand that the above examples are mainly used to illustrate the position relationship among the text contents of the table tag, tr tag, td tag,/td tag, and cell, and in particular, when performing the conversion, other sequences may be adopted as long as the table can be converted into the HTML content.
On the other hand, for a table, there may be other attribute data, such as the frame width of the table, the cell pitch, and so on. When the attribute data corresponding to the table comprises the frame width of the table and the space between the cells, the border attribute of the table label can be set as the frame width; and setting the cellpacking attribute of the table label as the space of the cells, and realizing the conversion from the two attribute data of the table to the HTML content.
TABLE 1
| First | Row |
| Second | Row |
Taking the table shown in table 1 above as an example, after converting the HTML content, the code of the converted HTML content can be as follows:
it can be seen that each row in the table is converted to a < tr > tag, each cell is converted to a < td > tag, and the text content of the cell is converted to text content in the middle of the < td > </td > tag. Compared with the existing mode that the position of the rectangle of each cell needs to be calculated, then the canvas graphic drawing interface drawRect function is called to draw on bitmap, and the text content in the cell also needs to calculate the specific position information of the text and then calls the drawText interface to draw, the process of analyzing and converting is very simple.
Taking the content type as a video as an example, a video tag is arranged in html (hypertext markup language) and used for displaying video files in various formats, after the file content is analyzed, the video obtained by analysis can be stored in the intelligent terminal, and a video storage path for storing the video is recorded; and acquiring the video width, the video height and the video type in the attribute data corresponding to the video. And then adding a video tag in the HTML content, setting the src attribute of the video tag as the video storage path, setting the width attribute as the video width, setting the height attribute as the video height and setting the type attribute as the video type.
Taking an mp4 format video file as an example, after parsing, the code of the converted HTML content may be as follows:
<video width＝"320"height＝"240"controls>
< source src ═ video storage Path ═ video/mp4 >
</video>
According to the current technical development situation, web browsing software (such as a browser) generally supports a video tag, and video files are played in the web browsing software. Under the condition that the webpage browsing software does not support the video tag, a player plug-in corresponding to the type attribute can be called to play the video with the src attribute according to the height attribute and the width attribute of the video tag, namely, the video is rendered and displayed by calling the player plug-in. When playing, based on the width attribute and height attribute of the video tag, the video can be zoomed.
Taking the content type as audio, such as an audio file, audio tags in HTML are used for displaying audio files in various formats, and after the file content is analyzed, the audio obtained through analysis can be stored locally in the intelligent terminal, and an audio storage path for storing the audio is recorded. Then, an audio tag is added to the HTML content, and the src attribute of the audio tag is set as the audio storage path.
In an audio file with mp3 format, the html code obtained after parsing and conversion may be as follows:
< audio src ═ handset path where audio file is located "controls ═ controls" >, and
</audio>
according to the current technical development situation, the web browsing software (e.g. browser) generally supports the audio tag, so as to realize the audio playing in the web browsing software. Under the condition that the webpage browsing software does not support the audio tag, a related audio playing plug-in can be called to play the audio with the src attribute according to the audio tag, namely, the audio playing plug-in is called to play and render the audio.
Based on the above exemplary content, it can be determined that, because HTML is a simple language and is easy to master, and HTML encapsulates a plurality of attribute interfaces, which are basically consistent with interfaces required after parsing document content, and correspond to each other one by one during processing, the process of converting file content into HTML content for display reduces the problems of recalculation caused by mismatch between parsed attribute values and interface parameter values provided by a converter and need to encapsulate system interfaces again in many cases, and is more efficient to use, and reduces the complexity of the rendering process of the local rendering technology. The converted HTML content can form an HTML webpage, and then the webpage is displayed through related webpage browsing software (such as a web browser or other HTML webpage browsing software), so that the interactivity can be well improved.
Based on the same idea as the method, an embodiment of the present invention further provides a device for displaying a file on an intelligent terminal, and fig. 5 illustrates a schematic structural diagram of the device for displaying a file on an intelligent terminal in an embodiment.
As shown in fig. 5, the apparatus in the present embodiment includes:
a content obtaining module 501, configured to obtain file content of a file to be displayed;
an analyzing module 502, configured to analyze the file content to obtain each content structure of the file content;
a conversion module 503, configured to convert each content structure into web page content;
and a display module 504, configured to display the converted web page content through web page browsing software.
According to the scheme of the embodiment of the invention, when the file to be displayed of the intelligent terminal is displayed, the file content of the file to be displayed is obtained and then analyzed to obtain the content structure of the file content, the content structure is converted into the webpage content, and then the webpage content is displayed through the webpage browsing software, so that various bottom interfaces of the system are not needed to be used, the bottom interfaces are not needed to be packaged, the webpage content is converted into the webpage content, and the webpage is displayed by means of the webpage browsing software technology for typesetting, rendering and displaying, so that the whole rendering and displaying process is simplified, the file can be displayed on the intelligent terminal in a simplified manner, and the displaying efficiency is high.
The file content of the file to be displayed, which is obtained by the content obtaining module 501, may be loaded into a local memory for storage and then analyzed. Accordingly, as shown in fig. 5, in a specific example, the apparatus in the present embodiment further includes a memory loading module 505.
The memory loading module 505 is configured to load the file content acquired by the content acquiring module 501 into the local memory.
At this time, the analysis module 502 is configured to analyze the file content loaded into the local memory to obtain each content structure of the file content.
Therefore, after the file content is obtained, the file content is loaded into the local memory, and then the file content loaded into the local memory is analyzed, so that the continuity and the fluency of the analysis and display processes can be ensured.
It can be understood by those skilled in the art that, in addition to loading the file content into the memory, other manners may also be used to process the file content, and accordingly, the continuity of parsing and displaying is ensured.
In the data stream of the file content, for different file formats in the file content, some specified fields in the related data stream may include information of the file format, and corresponding other related fields may include specific content information of the file format, so a person skilled in the art can clearly understand that, when the file content is analyzed, various file formats and related specific contents included in the file content may be determined by analyzing bytes of the related fields based on the difference of the file formats, and the analysis and analysis processes may be performed in any possible manner existing at present and possibly occurring later, and thus, the analysis process is not expanded to be described repeatedly.
After the analysis, a content structure of the file content is obtained, where the content structure may specifically include a content type and attribute data corresponding to the content type. The content types may be many, such as pictures, tables, text, graphics, icons, formulas, symbols, audio, video, etc., but may be other content types not listed here. The content types of the content of the file may vary from file to file, and are typically one or more of various content types, as well as various combinations of these content types.
HTML (HyperText Markup Language) is a Markup Language for designing and creating web pages and other information that can be viewed in web browsing software, and its documents are not complicated to make, but powerful, and support the embedding of files in different data formats. Accordingly, in one specific example, the web page content may be HTML content. In addition, because the CSS is a style design language that can truly separate web page representation from content, compared with the representation of the conventional HTML, the CSS can perform pixel-level precise control on the position layout of objects in a web page, support almost all font and font styles, have the capability of editing web page objects and model styles, and can perform preliminary interactive design, and thus, the web page content can also be HTML CSS content.
At this time, taking the web page content as HTML content as an example, as shown in fig. 5, in a specific example, the converting module 503 includes:
a tag adding module 5031, configured to add, according to content types respectively included in the content structures, tags corresponding to the content types in an HTML language;
a tag attribute setting module 5032, configured to set attribute contents of each tag corresponding to each content type according to the attribute data corresponding to each content type, respectively, so as to obtain the converted HTML content.
The following description will illustrate the parsing and conversion process related thereto by taking several different content types as examples.
Taking the content type including the picture as an example, the parsing module 502 may store the parsed picture locally in the intelligent terminal, and record a picture storage path for storing the picture. At this time, the tag adding module 5031 may add img tags in the HTML content, and the tag attribute setting module 5032 sets src attributes of the img tags as the picture storage paths, so as to implement conversion from pictures to corresponding HTML content.
On the other hand, for pictures there may be other attribute data, such as a centered display picture. At this time, when the attribute data corresponding to the picture includes the center display picture, the conversion of the attribute data of the center display picture into the HTML content can be realized by setting the style attribute of the div tag to text-align: center.
Taking the content type including the table as an example, the tag adding module 5031 may add a table tag in the HTML content; adding corresponding tr labels for each row of the table respectively; adding td labels and/td labels respectively corresponding to the cells after tr labels corresponding to the rows according to the number of the cells of each row of the table; the tag attribute setting module 5032 adds the text content of each cell to the td tag and/td tag corresponding to the cell, thereby realizing the conversion from the picture to the corresponding HTML content.
On the other hand, for a table, there may be other attribute data, such as the frame width of the table, the cell pitch, and so on. When the attribute data corresponding to the table comprises the frame width of the table and the space between the cells, the border attribute of the table label can be set as the frame width; and setting the cellpacking attribute of the table label as the space of the cells, and realizing the conversion from the two attribute data of the table to the HTML content.
Taking the case that the content type includes a video as an example, the attribute data corresponding to the video generally includes a video width, a video height, and a video type; at this time, the analysis module 502 may store the video obtained by analysis locally in the intelligent terminal, and record a video storage path in which the video is stored; and acquiring the video width, the video height and the video type in the attribute data corresponding to the video. In specific conversion, the tag adding module 5031 may add a video tag to the HTML content, and the tag attribute setting module 5032 sets the src attribute of the video tag as the video storage path, the width attribute is the video width, the height attribute is the video height, and the type attribute is the video type, so as to implement conversion from the video to the corresponding HTML content.
According to the current technical development situation, web browsing software generally supports video tags, and video files are played in the web browsing software. Under the condition that the webpage browsing software does not support the video tag, a player plug-in corresponding to the type attribute can be called to play the video with the src attribute according to the height attribute and the width attribute of the video tag, namely, the video is rendered and displayed by calling the player plug-in. When playing, based on the width attribute and height attribute of the video tag, the video can be zoomed.
Taking the content type including the audio as an example, at this time, the analysis module 502 may store the audio obtained by analysis locally in the intelligent terminal, and record an audio storage path for storing the audio. Specifically, when the conversion is performed, the tag adding module 5031 may add an audio tag in the HTML content, and the tag attribute setting module 5032 sets the src attribute of the audio tag as the audio storage path, thereby implementing the conversion from the audio to the corresponding HTML content.
According to the current technical development situation, the webpage browsing software generally supports the audio tag, and the audio is played in the webpage browsing software. Under the condition that the webpage browsing software does not support the audio tag, a related audio playing plug-in can be called to play the audio with the src attribute according to the audio tag, namely, the audio playing plug-in is called to play and render the audio.
It will be understood by those skilled in the art that the apparatus for displaying files on an intelligent terminal according to the above-described embodiment of the present invention may be integrated with web browsing software and used as a part of the web browsing software. In view of the data flow of the web browsing software and the difficulty level of maintaining the web browsing software, the apparatus for displaying files on the intelligent terminal according to the embodiment of the present invention may also be implemented in the form of a plug-in. The webpage browsing software can provide a file path of a file to be displayed to the plug-in, the plug-in acquires the file content of the file to be displayed, analyzes and converts the file content to obtain converted HTML content, and then transmits the converted HTML content to the webpage browsing software for display, and the HTML content can be directly displayed in a form of an HTML webpage by means of the self-capability of the webpage browsing software. In fact, the device for displaying files on the smart terminal according to the embodiment of the present invention is not limited to the above two modes, and the object of the embodiment of the present invention may be achieved.
