The method for realizing image-text mixed arrangement by using the textView text tool mainly comprises the following steps: creating a compound text constructor SpannablestringBuilder, and using the compound text constructor to assign the text content to be' the text content is the text and the picture in a picture and text mixed and arranged message [ image ] message, wherein [ image ] is used for occupying the picture to be inserted, and simultaneously determining the position of [ image ] in the whole text, such as the starting position is 10, and the ending position is 17. And then, creating a picture element ImageSpan, assigning a picture to be inserted to the picture element ImageSpan, assigning the picture element ImageSpan to the compound text constructor, and specifying the position of the picture element ImageSpan as the position of [ image ] in the whole text, namely, the starting position is 10, and the ending position is 17. In other words, [ image ] is used for occupying the whole text for the picture element ImageSpan, and the picture element ImageSpan assigns a picture and then places the picture in the occupied position, thereby realizing the simultaneous output of the picture and the text. Therefore, essentially, only text output can be realized by the textView text tool, and simultaneously, pictures and texts are output in the mode, which is long in time consumption.
Therefore, the embodiment of the invention provides a method for realizing mixed arrangement of pictures and texts, which realizes simultaneous output of pictures and texts by defining independent picture elements and text elements in a ChatView control, and can realize automatic line feed of the pictures and the texts at the same time, so as to greatly improve the running time of a system.
The method and the device for realizing mixed arrangement of the images and the texts provided by the embodiment of the invention are applied to electronic equipment, and the electronic equipment can be, but is not limited to, electronic equipment such as a computer or a mobile phone.
Fig. 1 is a schematic flow chart of a method for implementing mixed text-image arrangement according to an embodiment of the present invention, where the method includes:
in step S110, a picture element and a text element are created independently of each other.
The invention defines two mutually independent elements, namely DrawableElement and TextElement, wherein DrawableElement is a picture element, and TextElement is a text element.
And step S120, obtaining the picture through the assigned picture address in the picture element.
And after the picture address is assigned to the picture element, the electronic equipment acquires the picture through the picture address. As assigning a path of a picture to a picture element through drawable. Getdrawable () loads a picture specifying an ID as well. After the electronic equipment obtains the picture, the width and the height of the loaded picture are obtained and stored through a getIntrinsicWidth () method and a getIntrinsicHeight () method.
In step S130, the text content is assigned by the text element to obtain the text.
The text is obtained by assigning the text content to the text element TextElement.
And step S140, drawing the acquired picture and the acquired text on a canvas of the electronic equipment in sequence.
Fig. 2 is a schematic flow chart of a substep S140 of a method for implementing mixed image-text arrangement according to an embodiment of the present invention, where the substep S140 includes:
step S141, the heights of the picture and the text are obtained.
The picture obtained by the picture element and the text obtained by the text element both have a certain height, and therefore, the height of each picture and the height of each text are obtained.
In step S142, if the height of the picture or the text to be drawn on the canvas of the electronic device is less than the line height of the current line of the picture and the text, the canvas is moved by a preset distance so that the picture and the text are centered in the vertical direction of the current line.
The calculation method of the current line height is as follows: recording the height of the previous data drawn on the canvas by the current line, wherein the previous data can be a picture or a text, comparing the height of the current data drawn on the canvas with the height of the previous data, the current data can be a picture or a text, if the height of the current data is higher than that of the previous data, the height of the current data is the height of the current line, and if the height of the current data is lower than or equal to that of the previous data, the height of the previous data is the height of the current line.
Due to the inconsistent height of the data (pictures or texts) drawn on the canvas, when the height of the pictures or texts drawn on the canvas is less than the height of the current line, the canvas is moved downwards by a preset distance, so that the pictures or texts drawn on the canvas are always in a vertically central position on the current line. The preset distance is the difference value of the height of the current line minus the height of the picture or text drawn in real time, and half of the difference value is taken as the preset distance. And when the next picture or text relative to the picture and the text needs to be drawn, moving the canvas up by the preset distance so that the next drawn picture or text can be drawn normally.
And S150, when the total width occupied by the picture and the text exceeds the width of the screen of the electronic equipment, changing lines so as to be conveniently displayed on the screen of the electronic equipment for a user to check.
Fig. 3 is a schematic flow chart illustrating a sub-step of step S150 of a method for implementing mixed image-text arrangement according to an embodiment of the present invention, where the step S150 includes:
and step S151, obtaining the individual widths of the picture and the text, and calculating the actual occupied widths of the picture and the text in the current line according to the individual widths of the picture and the text.
The picture obtained by the picture element and the text obtained by the text element both have a certain width, so that the individual width of each picture and each text is obtained.
And calculating the actual occupied width of all the pictures and texts in the current line according to the number of the pictures and texts in the current line and the individual width of each picture and each text.
Step S152, calculating and calculating the width of the residual screen according to the width actually occupied by the picture and the text on the current line.
And calculating the residual screen width of the current line according to the screen width of the electronic equipment and the actual occupied width of the picture and the text in the current line.
Step S153, acquiring total characters of the text to be input.
All the text quantities obtained by the text elements are calculated and stored.
Step S154, a truncation function is called to calculate the number of remaining total characters that can be accommodated by the remaining screen width according to the truncation position of the total character and the remaining screen width, where the number of remaining total characters is the number of characters counted by the total character from the truncation position.
Fig. 4 is a schematic diagram illustrating an example of practical application of the image-text mixed arrangement implementation method according to the embodiment of the present invention. Such as: all text contents needing to be input are acquired through the text elements, namely, an image-text mixed message which has characters and pictures, when the character information is too long, line feed can be automatically cut off, and all the pictures needing to be input, namely, a ball, an airplane, a magnifying glass, a mobile phone and a lock chain, which are shown in the figure, are acquired through the picture elements.
The picture and the characters displayed in the picture are divided into two lines, the sum of the widths of the characters in the first line, namely a text-text mixed message, the width of the message of the existing characters and the width of the picture, namely the sphere, is equal to the width of the screen, the character content is cut off from the position of the picture in the message of the existing characters and the picture, the position is a cut-off position, the rest of the character content is displayed in the next line by automatically cutting off and changing lines when the character message is too long, and the character quantity of the rest of the character content is the character quantity of the total characters calculated from the cut-off position, namely the quantity of the rest of the total characters.
In the second line, a plurality of pictures, such as an airplane, a magnifier, a mobile phone and a chain, are drawn in sequence, the pictures occupy a certain screen width, and then a truncation function is called to calculate the number of the remaining characters which can be contained in the remaining screen broadband according to the truncation position of the total characters and the remaining screen width, namely, the number of the characters in the line which can be automatically truncated and changed when the character information is too long can be contained in the remaining screen width of the line. Meanwhile, as shown in the figure, the heights of the pictures and the characters and the height of the current row are always compared in real time in the drawing process of the characters and the pictures to ensure that the pictures and the characters are positioned at the vertical central position of the current row, and then the characters and the pictures show the effect of central level.
Step S155, if the number of remaining total characters that can be actually accommodated by the remaining screen width is smaller than the number of remaining total characters, the width occupied by the picture and the text exceeds the screen width of the electronic device.
If the number of characters that can be actually accommodated by the remaining screen width is smaller than the number of the remaining characters, that is, smaller than the number of characters in "when the text message is too long, the line feed can be automatically truncated", which indicates that the width occupied by the picture and the text of the current line will exceed the screen width of the electronic device, and the line feed is required, so that the user can enjoy a better display effect. Fig. 5 is a schematic diagram illustrating an example of a practical application of another image-text mixed arrangement implementation method according to an embodiment of the present invention. The "truncated line feed" character is automatically displayed in the next line because it cannot be accommodated by the remaining screen width of the current line.
In addition, the electronic equipment stores the number of characters actually contained in the remaining screen width of the current line and the next truncation position of the characters, so as to judge whether the remaining character amount can be contained in the screen width of the next line. Meanwhile, the electronic equipment also records the actual occupied width of the picture and the text of the current line, so that when the picture or the text of the next line is drawn on the canvas, the canvas can be moved to the left by the actual occupied width of the picture or the text of the previous line, and the picture or the text of the next line is drawn conveniently.
