Description

Method and device for processing emoticon character strings

technical field

The invention relates to the field of computer technology, in particular to a method and device for processing emoticon character strings.

Background technique

The meaning of Emoji comes from Japanese えもじ, which means characters in Japanese. It is a visual emotional symbol used in wireless communication in Japan. After the introduction of Emoji in the IOS 5 input method released by Apple, this kind of emoticon gradually became popular. At present, picture emoticons have been widely used in almost all mobile chat software, such as WeChat, Yixin, and QQ all support the sending of emoticons. A picture emoticon is essentially a character string conforming to a specific format. Most of the implementation schemes establish a correspondence between the picture emoticon and its corresponding string, for example, "[:smile]" corresponds to the "smiling" emoticon, " [:cry]" corresponds to the "cry" emoji.

The TextView control that comes with the operating system has a powerful image-text mixing processing capability. It mainly uses the image-text mixing function SpannableString to conveniently convert text to image expressions, and can replace text within the specified range with Emoji expressions, but although Emoticons are displayed within the specified range. In fact, the original strings are still stored inside the TextView control, that is, the image emoticons and strings are regarded as two separate entities, which causes some applications (such as input methods) to display image emoticons. During processing, it is necessary to execute the image emoticon multiple times to complete the operation. For example, Figure 1 shows an example diagram of the client inputting a picture emoticon in the prior art, the picture emoticon ranked second in Figure 1 needs to be deleted, and Figure 2 shows that the client performs picture emoticon deletion in the prior art An example picture of emoticon coding appears afterward. It can be seen from Figure 2 that after deleting the picture emoticon, the original string "/::" in the background still exists and is displayed on the client interface. If you need to replace "/::" If you want to delete, you need to perform the delete operation twice.

It can be seen from this that in the prior art, the image expression processing operation may require multiple operations to complete, and the increase in the number of operations will waste corresponding resources and also increase the difficulty of the operation.

Detailed ways

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

In order to solve the above technical problem, an embodiment of the present invention provides a method for processing emoticon character strings. Fig. 3 shows a processing flowchart of a method for processing emoticon character strings according to an embodiment of the present invention. Referring to Fig. 3, the method at least includes the following steps S302 to S304.

Firstly, step S302 is executed, and for the picture expression having the first mapping relationship between picture expression and expression character string, on the basis of the first mapping relationship, a second mapping relationship between expression character string and unicode (unicode) is added.

It should be noted that, in the embodiment of the present invention, the first mapping relationship between picture emoticons and expression character strings is an existing mapping relationship in the expression library, and because of certain loopholes in the recognition of the first mapping relationship, the picture expression and the emoticon string may be regarded as two separate entities, and then it needs to be executed multiple times to complete the processing of the image emoticon. To solve this technical problem, the embodiment of the present invention improves the first mapping relationship, and adds a second mapping relationship on the basis of the first mapping relationship, that is, the mapping relationship between emoticon character strings and unique codes.

Specifically, in one embodiment, an Emoji expression storehouse is set, and this expression storehouse contains commonly used picture expression, and stores the first mapping relation of picture expression and its corresponding character string in this Emoji expression storehouse simultaneously, in addition, this Emoji class all Image emoticons can be saved in class directories (for example: assets directory).

According to the second mapping relationship between emoticon character strings and unicode mentioned in step S302, the emoticon character strings in the Emoji expression library of this embodiment are processed, and the corresponding unicode is set for them. It should be noted that unicode is an international standard encoding used on computers, which can represent characters, pictographs and other symbols that may be used for computer communication in all written languages in the world with a unified and unique binary code. It is precisely because of the uniqueness of unicode that the mapping relationship established between the picture expression, the expression string and unicode is also unique, so that each picture expression can be represented by a unique character. When executing the program, due to the uniqueness of the default unicode in the background and the uniqueness of the mapping relationship established by the three, the other two elements can be found through any element in the unique mapping relationship, so that the operation of the picture expression is also available. Uniqueness. When operating on any element, the other two elements involved can be processed according to the unique mapping relationship established between the picture expression, expression string and unicode, which can ensure that the picture is completed at one time. Expression processing, thereby avoiding problems such as time slowness, resource waste, and poor user experience caused by multiple operations for one expression processing. Further, in order to ensure that all the expressions in the entire Emoji expression library will not be processed multiple times to complete a processing requirement, preferably, all the picture expressions in the entire Emoji expression library can be added with a second mapping relationship, so that the expression library Each picture expression in the library can be mapped to a unique unicode. When processing any picture expression in the expression database, due to the uniqueness of unicode and the uniqueness of the mapping relationship established by the three, the operation and processing of each picture expression are uniform. Can be done in one go.

Among them, in the embodiment of the present invention, the added single code is set in the blank area of the client to make full use of the blank area of the client, and the added single code is clear and concise, and the mapping relationship of the added is also easy to obtain, avoiding conflicts with other existing The codes are confused in the same area, resulting in confusion caused by code superposition, and also reduces the difficulty of acquisition.

In practical applications, the second mapping relationship between the added emoticon string and unicode can be saved in the class directory (such as the assets directory) through a lightweight data exchange format (such as: json), and can be defined as a mapping in the following format surface:

{"unicode":"0xF001","imgCode":"[:smile]"}

{"unicode":"0xF002","imgCode":"[:cry]"}

When the picture expression processing program is running, the above mapping table is loaded into the memory for the client to search, extract, process and so on.

After adding the second mapping relationship in step S302, the embodiment of the present invention executes step S304 to combine the first mapping relationship and the second mapping relationship to establish a corresponding mapping relationship between the picture expression and the single code.

Specifically, FIG. 4 shows a schematic diagram of the mapping relationship between picture emoticons, emoticon character strings and unicode according to an embodiment of the present invention. Referring to FIG. 4 , the combination of the first mapping relationship and the second mapping relationship is realized through the emoticon character string, so that a corresponding mapping relationship is established between the picture emoticon and unicode. Taking the smile expression as an example, combining the first mapping relationship between the smile picture expression and the smile expression string "[:smile]" and the second mapping relationship between "[:smile]" and the single code "0xF001", the smile picture expression and the single The code "0xF001" establishes the corresponding mapping relationship.

In summary, the embodiments of the present invention provide a method and device for processing expression strings. Since the first mapping relationship between picture expressions and expression strings has certain loopholes when used to identify picture expressions, the difference between picture expressions and expression strings The character string may be regarded as two separate individuals. At this time, if the expression needs to be processed, it may need to be executed many times to complete the processing. To solve this technical problem, the present invention adds expression string and unicode The second mapping relationship, unicode is an international standard encoding used on computers, which can use a unified and unique binary code to represent characters, pictographs and other symbols that may be used for computer communication in all written languages in the world, That is, unicode is unique. It is precisely because of the uniqueness of unicode that the mapping relationship established between the picture expression, the expression string and unicode is also unique. At this time, if the picture expression is processed, any element in the unique mapping relationship The other two elements can be found, so that the operation of the picture expression is also unique. When operating any element, it can be based on the unique mapping relationship established between the picture expression, expression string and unicode. The other two elements involved are processed, so the image expression processing can be completed at one time, thereby avoiding problems such as slow time, waste of resources, and poor user experience caused by multiple operations for one expression processing.

After the corresponding mapping relationship between the picture expression and the single code is established (ie step S304), if a processing message of a certain picture expression is received, the picture expression can be processed according to the added unicode. Specifically, FIG. 5 shows a processing flow chart of a processing manner of image emoticons according to an embodiment of the present invention. Referring to Fig. 5, the method at least includes steps S502 to S504.

Step S502, when receiving a processing message of a picture expression, use the corresponding mapping relationship established between the picture expression and the single code to find the single code corresponding to the picture expression;

Step S504, execute the processing operation carried in the processing message of step S502 on the found unique code.

In the embodiment of the present invention, as mentioned above, due to the uniqueness of the single code, the mapping relationship between the three is also unique, so that the operation on the picture expression is also unique. After the single code is executed and the processing operation is completed, Make the picture expression on the operation interface have a unique character representation in the background program, and then when the picture expression is processed, the background will process the picture expression and the expression string corresponding to the single code, thereby avoiding the need for one expression processing Problems such as slow time, waste of resources, and poor user experience caused by multiple operations.

In the embodiment of the present invention, the implementation subject of the above steps may be an instant messaging client, such as QQ, Yixin, WeChat, SMS, MMS, etc., which can use text formats such as text and pictures to communicate.

Further, in a preferred embodiment of the present invention, the finding of the single code corresponding to the picture emoticon mentioned in step S502 may specifically include the following steps:

Step 1, according to the first mapping relationship between the picture expression and the expression string, find the expression string corresponding to the picture expression;

Step 2. According to the second mapping relationship between the emoticon character string and unicode, according to the emoticon character string found in step 1, further find the unicode corresponding to the emoticon character string.

Specifically, taking a smiley expression as an example, when inputting a smiley picture expression, the first mapping relationship established when the program is running, finds the expression string "[:smile]" corresponding to the smiling picture expression, and adds the established second mapping relationship, find out the unique code "0xF001" corresponding to the emoticon string.

In a preferred embodiment of the present invention, as mentioned in step S504, performing the processing operation carried in the processing message on the found single code may include the following steps:

Step 1. Call the processing function corresponding to the processing message;

Step 2, utilizing the processing function to set the conversion relationship between the single code and the image emoticon bitmap;

Step 3: Use the processing function to execute the processing operation carried in the above processing message on the single code, and use the conversion relationship between the single code and the picture expression bitmap to map the processing operation to the picture expression bitmap.

In the embodiment of the present invention, the processing function mentioned in step 2 is used to set the conversion relationship between the single code and the picture expression bitmap, wherein the picture expression bitmap is formed by analyzing all picture expressions in the Emoji expression library, that is, at first the picture needs to be The expression is converted into a Windows standard format graphics file, and then the Windows standard format graphics file is analyzed to form a bitmap file (bitmap). The bitmap uses a pixel array to represent the picture expression, and the picture expression is defined as being composed of points (such as pixels). Each point can be represented by a variety of colors, including 2, 4, 8, 16, 24, and 32-bit colors. After parsing each picture expression into a corresponding bitmap file bitmap, pair the corresponding bitmap with its corresponding file name, and save the pairing result with a list (List). The items in the List can be defined as the following format,

Take the smiley emoji as an example,

Each image expression in the database is parsed into a corresponding bitmap and stored. Correspondingly, when the image expression is processed, the corresponding bitmap can be called and displayed on the client interface.

Specifically, taking the smiley expression input as an example, after searching for the single code "0xF001" corresponding to the smiley picture expression, since the input part includes pictures, a new graphic-text mixing function SpannableString needs to be created in the Textview control when the program is running, and then call the setSpan function to set The conversion relationship between the single code "0xF001" and the bitmap file corresponding to the smiling picture emoticon is to convert the found single code "0xF001" into a bitmap file, and finally insert the obtained SpannableString into the current cursor position of the edit text to complete the smiley picture emoticon enter.

For commonly used instant messaging clients, information transmission is two-way. Any information (commonly text information) is generated by the local client, and after uploading to the server, the server processes the information, and then the processed information Forward to the other client. It can be seen that, after the information is generated, both the server and the counterpart client need to be able to identify the corresponding information. However, in the embodiment of the present invention, the second mapping relationship is added to the picture expression. If the picture expression including the second mapping relationship is directly sent out, neither the server nor the other client may be able to recognize it.

Therefore, taking the text content as an example, in order to ensure that the server can recognize the text content and completely forward the text content to the counterpart client, the text content needs to be processed. Fig. 6 shows a flow chart of uploading the text to the server after the text including at least one emoticon is input according to an embodiment of the present invention. Referring to FIG. 6 , the text upload process includes at least step S602 to step S608 .

Step S602, acquiring the text content of the text;

Step S604, parsing out the single code, using the reverse mapping relationship between the single code and the expression string stored in the expression library to find the corresponding expression string;

Step S606, using the found corresponding emoticon character string to replace the position of the single code in the above text;

Step S608, uploading the text obtained after the replacement to the server.

In the embodiment of the present invention, step S604 utilizes the reverse mapping relationship between emoticon character strings and unicode to find the emoticon character string corresponding to unicode. FIG. Schematic diagram of the mapping relationship. In practical applications, the mapping relationship between picture emoticons, emoticon strings and unicode is reversible. For example, some smart machine kernels can recognize emoticon strings. In actual processing, the reverse of emoticon strings and picture emoticons can be used. The mapping relationship finds the picture expression, and then displays the picture expression. Similarly, there may be some terminals whose background can only recognize unicode, and then can find the corresponding picture expression according to the indirect reverse mapping relationship between unicode and picture expression, and display it on the terminal interface.

Specifically, taking the text content including smiling emoticons as an example, when the client uploads the text content to the server, it needs to perform the following processing. First, obtain the text content in the edit text (EditText), and parse out the single code in the text content "0xF001", find the smile expression string "[:smile]" through the reverse mapping relationship between the single code "0xF001" and the corresponding expression string, and replace the smile expression string "[:smile]" with the single code "0xF001 ", and finally upload the replaced text to the server.

In the text content processing flow shown in Figure 6, the text content using the second mapping relationship is processed, the corresponding emoticon string is searched according to the reverse mapping rules of the single code and the emoticon string, and then the found emoticon string is used The position of the single code in the text is replaced, and the modification makes the text information return to the original text information before the second mapping relationship is not used. Subsequently, the recovered original text information is uploaded to the server for transmission by the server. The purpose of the recovery operation shown in Figure 6 is to effectively prevent the server from not recognizing the added unicode, to avoid problems such as garbled text content when the server recognizes the text content, or to avoid transmission errors and lost data when transmitting text to other clients. package etc. On the other hand, the recovery operation shown in Figure 6 is performed on the client side without the participation of the server, and the server does not need to add a new data analysis method for the mapping relationship between the added emoticon character string and the single code, and does not need to make any changes. Therefore, the embodiment of the present invention can complete the image expression processing operation without changing the server and increasing the hardware cost, saving a lot of resources. To sum up, the above text content processing operation is more conducive to the server responding to the service request and ensuring the quality of the service.

In addition, the first mapping relationship between picture expressions and expression strings and the second mapping relationship between expression strings and unicode proposed by the present invention are transparent to the server, and the server does not need to do additional compatibility processing.

Next, take the client as a specific embodiment of the present invention to further illustrate the present invention by sending the text content of "Today the teacher sent Xiao Ming a little red flower (here is the picture expression of "Little Red Flower")" to the other party's client. The process flow of the inventive processing method for emoticon character strings and the beneficial effect when the image emoticons generated according to the present invention are processed and operated.

The text content that needs to be input includes not only the text content of "Today the teacher sent Xiao Ming a little red flower", but also the picture content of "Little red flower". After the client edits the text and enters the text part of "Today the teacher sent Xiao Ming a little red flower", it needs to input the picture expression of the little red flower. At this time, the background program will, according to the first mapping relationship between the picture expression and the expression string, Find the expression string "[:red flower]" corresponding to the expression of the little red flower picture, and then find the single code "0xF003" corresponding to "[:red flower]" according to the second mapping relationship between the added expression string and unicode ". Afterwards, the single code "0xF003" performs processing operations. First, edit the text in the Textview control to create a new image-text mixing function SpannableString, and then call the setSpan function to convert the single code "0xF003" into a bitmap file of the little red flower picture expression, and the obtained SpannableString Insert it into the edit text at the current cursor position to complete the input of the little red flower picture emoticon. After the client completes the input of the text content of "Today the teacher sent Xiao Ming a little red flower (here is the picture expression of "Little Red Flower")", it needs to upload the text content to the server, and the server forwards it to the other party client. Since the emoticon of the little red flower in the text content is input through the processing operation of the added single code "0xF003", in order to ensure that the server can recognize the emoticon of the little red flower, it needs to be processed as follows to obtain "Today the teacher sent Xiaoming A little red flower (here is the "little red flower" picture emoticon)" text content, parse out the single code "0xF003" of the little red flower picture emoticon in the text content, and according to the reverse of the single code and the expression string Mapping relationship, find the emoticon string "[:red flower]" corresponding to the single code "0xF003", and replace the single code "0xF003" with "[:red flower]" in the background, that is, the text information is restored to the unused number Before the two mapping relationships, the recovered text information is uploaded to the server, and the server transmits it to the other client.

It should be noted that the "Little Red Flower" picture emoticon in the text content is input through the operation of the added single code "0xF003". Due to the uniqueness of the single code "0xF003", the little red flower picture emoticon, "[ The mapping relationship established between :redflower]" and the single code "0xF003" is also unique. When the "Little Red Flower" picture emoticon is deleted or copied, when the program is executed in the background, due to the uniqueness of the default "0xF003" and the uniqueness of the relationship established between the three, the operation of the little red flower picture emoticon is also With uniqueness, the three elements involved in the expression of the little red flower picture, "[:red flower]" and the single code "0xF003" are all processed, so the processing operation can be completed at one time.
