s1: a user screen capture command is acquired.
In the embodiment of the application, the operation of performing screen capturing can be performed in various manners, for example, a user can perform screen capturing by using the mobile terminal, and also can perform screen capturing by using software. Further, there are various ways to obtain the user screen capturing command, for example, the user may click the screen capturing operation function button on the display interface of the mobile terminal, and the display interface of the mobile terminal obtains the "click" operation so as to obtain that the user wants to perform the screen capturing operation; or, the user may send a voice control command to the mobile terminal, for example, send a voice control command of "screen capturing" to the microphone of the mobile terminal, so that the mobile terminal knows that the user wants to perform the screen capturing operation; or the user can use the third party device to control the mobile terminal, and the third party device sends a specific control command to the mobile terminal, so that the mobile terminal can know that the user wants to perform screen capturing operation; or, the user may perform a specific action operation on the mobile terminal, for example, click on the display interface of the mobile terminal twice within a preset time, so that the mobile terminal knows that the user wants to perform the screen capturing operation. Of course, there are other ways to obtain the user screen capturing command, which will not be described herein.
S2: a virtual screen is created.
In the embodiment of the present application, after step S1, the mobile terminal knows that the user wants to perform screen capturing, and at this time, the mobile terminal system invokes the interface createVirtualDisplay in the class mediaproject.

s601: judging whether to acquire the storage authority of the mobile terminal; if yes, go to step S602; if not, go to step S603;
s602: storing the bitmap to the mobile terminal;
S603: and displaying an interface prompt of no storage permission on the mobile terminal.
In the embodiment of the present application, through the steps S601 to S603, the bitmap converted from the display content on the display interface of the mobile terminal is stored in the memory of the mobile terminal.
Referring to fig. 10, specifically, in embodiment 10 of the present application, the method for saving the bitmap on the server includes the following steps:
s604: judging whether the mobile terminal and the server successfully establish communication connection; if yes, go to step S605; if not, go to step S606;
s605: clicking a picture uploading function button in a floating window, and uploading the bitmap on the mobile terminal to the server;
s606: and prompting unsuccessful connection establishment on the display interface of the mobile terminal.
In the embodiment of the present application, through the steps S604 to S606, the bitmap converted from the display content on the display interface of the mobile terminal is uploaded from the mobile terminal to the server for storage.
Referring to fig. 11, specifically, in embodiment 11 of the present application, in the above-mentioned S1233, the method for forming the picture list includes the following steps:
s12331: acquiring the number N of the bitmaps in the picture set, and the storage time, the label and the description information of each bitmap;
S12332: constructing N sub-lists, and sequencing the N sub-lists;
s12333: sequentially placing the N bitmaps and the corresponding labels and description information into N sub-lists; wherein, each sub-list stores the same bitmap and all the labels and description information corresponding to the bitmap;
s12334: sorting the N sub-lists according to the sequence of the preservation time corresponding to the bitmap in each sub-list;
s12335: displaying the bitmap in each sub-list and the label corresponding to the bitmap, and hiding other information of the bitmap in each sub-list to form the picture list; wherein the other information includes the description information;
s12336: constructing a display trigger mechanism between the tag and the other information in the same sub-list, and displaying the other information in the sub-list when a preset action is executed on the tag;
s12337: and constructing a webpage jump mechanism between the description information and the bitmap in the same sub-list, and jumping to a webpage storage address of the bitmap when a preset action is executed on the description information.
In this embodiment, and in the sections that refer to tags and description information either before or after, the tags and description information are associated with a bitmap. Specifically, for example, when a bitmap is "western lake", then the label may be a refined vocabulary expression of "scenery", "lake", "western lake", etc., and the description information may be a detailed vocabulary expression of "western lake is beautiful", "photographed 1 month 1 day 2019", etc. More specifically, the tag may be one or more phrases or characters related to the picture content selected from a preset vocabulary set, so as to refine the picture content, so that the user can know the related aspects of the picture content without opening the picture; in addition, the label can also be a word or other characters with specific meanings which are added by the user, and the user can understand the content of the picture when seeing the label. Similarly, the description information and the labels are similar, and are not repeated here.
As an embodiment, the description information includes a saved web address of the bitmap on the server and a summary describing the bitmap.
The foregoing steps can be seen with reference to the schematic diagrams of fig. 14-16, and with reference to the accompanying drawings, it can be clearly seen that by placing N bitmaps and their respective labels and description information into N sub-lists, a picture list is formed, so that a user can browse and select pictures conveniently. In the embodiment of the present application, only the bitmap and the corresponding label thereof are displayed in the sub-list (wherein the bitmap is often displayed in the form of a thumbnail) in consideration of the aesthetic and refining characteristics of the picture list.
Of course, the user information is also convenient to obtain, and other information except the label in the bitmap information, including the saved website and abstract of the picture on the server, can be displayed under a certain display trigger mechanism, for example, related information can be obtained by touching and clicking the label mark in the sub-list; if the tag information is clicked, website information, text abstract information and the like can be further obtained, and by clicking the website information, a website to which the stored picture belongs can be accessed.
Referring to fig. 16, specifically, in an embodiment of the present application, when a user clicks on a "tab" in a sub-list, a website and a summary may be displayed in the sub-list, and the user may directly see more specific description information about the picture; when the user clicks the description information of the 'website' displayed in the sub-list, the user can directly jump to the webpage storage address of the bitmap, and the user can directly browse the bitmap in a webpage form through a browser.
Referring to fig. 12, specifically, in embodiment 12 of the present application, the method for storing the bitmap in the mobile terminal and/or the server includes the following steps:
S6021, obtaining the number M of all bitmaps (one stored picture is a bitmap) and the corresponding labels thereof; wherein the label is associated with the bitmap;
s6022, creating M bitmap sets, and sequentially placing M bitmaps into the M bitmap sets;
s6023, sequentially calculating the similarity of the labels of the bitmaps in the two adjacent bitmap sets;
s6024, comparing the similarity with a preset threshold value, and combining two bitmap sets exceeding the preset threshold value to form Q new bitmap sets;
s6025, creating Q folders in the mobile terminal and/or a server storage area, and sequentially placing all bitmaps in the Q bitmap sets into the Q folders; wherein each folder includes all bitmaps in the same bitmap set.
Specifically, in the step S6023, the method of sequentially calculating the similarity of the labels of the bitmaps in the two adjacent bitmap sets is to sequentially calculate the similarity of the labels of the bitmaps in the two adjacent bitmap sets by using a collaborative filtering algorithm.
In the embodiment of the application, M bit maps can be stored into Q folders according to the similarity of the labels by a collaborative filtering algorithm, so that the later search of a user on the mobile terminal is facilitated. For example, when two bitmaps are respectively "western lake" and "thunderpeak tower", their labels are "western lake" and "thunderpeak tower", and since the "western lake" and "thunderpeak tower" have a similarity exceeding a preset threshold, the two bitmaps can naturally be saved in the same folder. The preset threshold of the similarity can be set according to user definition or set by the processing amount of the comprehensive bitmap data of the system, and other factors such as different division standards.
