The order of input and they are sent to kernel go to perform.The function and be that the order line process created in the present invention is realized
The shell of system is identical, therefore is also named as shell.
Virtual key：Terminal virtual key refers to the virtual button in screen for full touch terminal, utilizes this
Button can be directly realized by the function of system button.
In the specific embodiment of the present invention, there is provided one kind is led in Android intelligent terminal screen optional position
The method that the virtual key of definition replaces long-press system in combination button to realize screenshotss is crossed, by the function of realization with the void on suspended window
The form for intending button is showed, and its benefit is can be suspended to the optional position of screen, and may be displayed on almost institute
, thus can be under any circumstance by operating virtual key come instead of pressing system in combination on some terminal applies interfaces
Button realizes screenshotss.We provide a suspension button first, such as the suspension button in red circle in Fig. 2, can be suspended into screen
Optional position, and can be suspended on most of terminal applies interface.A suspension can be ejected by clicking on suspension button
Window, while suspension button is closed.According to a preferred embodiment of the present invention, as shown in figure 3, suspended window size can be set
For for placing some buttons, these buttons correspond to different functions respectively, clicking on some button therein can realize accordingly
Function.In the specific embodiment of the present invention, exemplified by realizing screenshotss function, such as " cutting with reference to the middle part of figure 3
Screen " button.
After " screenshotss " key is clicked on, we are firstly the need of a sub-line journey is started, because the follow-up process of this scheme is one
It is individual to be performed than relatively time-consuming process, it is necessary to be put into sub-line journey, prevent that blocking main thread causes to crash.
Then, terminal is judged in sub-line journey, and whether Root is successful, prompts user to use this function if non-Root
Firstly the need of Root, and provide can be with the instrument download address of root termination, and then screenshotss flow can exit；If Root successes
, then authority that this application can be assigned by system ejection authorizes window, after user clicks on permission, just gets Root authority, no
Then prompt not authorize authority, operation performs failure.
After Root authority is obtained, filename corresponding to screenshot picture is then built.This filename can be as needed
It is defined, according to a preferred embodiment of the present invention, the character string generated with current time after formatting is made
For title, form as similar " yyyy-MM-dd-HH-mm-ss ", yyyy represents the time, and MM represents the moon, and dd represents day, HH
Hour is represented, mm represents minute, and ss represents the second, and it is not in duplication of name phenomenon that the file so generated, which ensures,.It is currently also other
Method, according to a preferred embodiment of the present invention, the filename of random number or timestamp as generation can be used.If
Using formatted. times as filename, then the time of file generated can be known from file name.Then, generation text is obtained
The part path to be saved in, this path can be write extremely in a program, can also be selected by user, be generally directed to SD card
Under some catalogue, such as picture directory, photograph catalogue etc., so it is easy to user to check the figure cut by picture browsing software
Piece.Finally by the path of setting, plus filename, and after " .png " (suffix name, representative are the pictures of png forms) is such
Sew name and be spliced into a complete file name, it includes routing information, file name information, file type information.
After a complete file name is generated, use " su " to be used as parameter, create shell performing environment,
Root authority will be asked for system when performing this instruction, because application has got authority before, here not
User is reminded to assign application permission again., will be shaped like character string as " the complete filenames of screencap " after creating successfully
Order is delivered in shell execute instruction environment by packaged method, and this instruction is then performed in shell environment,
Wherein " screencap " represents the feasibility file of system, it be used for realize screenshotss function, be generally present in system/
Under system/bin catalogues.It is the screenshotss program that system carries, and the java applet being different from, it is one binary
Executable program, it can only be performed in command line environment.This performs file and not opened to the outside world, only obtains System Privileges
Or the application of Root authority can just call it, so one of this patent scheme on condition that system must need Root, so
It could call and arrive this executable file.It is upon execution, it is necessary to a parameter-filename, and we have been passed to belt path here
Filename, the screenshotss content of generation is saved in Parameter File by so this executable file upon execution, ultimately generates and cuts
Shield file.
During screenshotss are carried out, it would be desirable to suspension button is hidden temporarily, avoid occurring in screenshot picture suspending by
Key, influence screenshotss effect.After the completion of screenshotss, it is necessary to by hiding suspension button show again for subsequently continue screenshotss or
The other operations of person.
After the completion of screenshotss, we, which generally require, shows the file of screenshotss generation by an animation, improves and cuts
The experience effect of screen.Meanwhile an informing message can be sent, can be logical by this customized informing message user
Know that the information of screenshotss is seen on column, including screenshotss generation file path information etc., and user is after informing information is clicked on, can be with
Under screenshotss file path corresponding to leaping to, checking for screenshotss effect is carried out.
By so a series of step, " virtual " is realized to the function of screenshotss, instead of long-press system in combination key and enter
Row screenshotss, and because adding animated show and informing is shown, user's screenshotss Experience Degree also greatly promotes.
In the specific embodiment of the present invention, there is provided detailed is instructed using shell, system executable file
The method that screencap realizes screenshotss, such as exemplary plot 4, the step of it is realized, is as follows：
S401, suspension button is clicked on, started；According to a preferred embodiment of the present invention, opened up using suspension button
Show holding state, specific function is realized using suspended window.Suspended window will be unfolded after clicking on suspension button, be suspended simultaneously
Button is hidden；After suspended window is closed, suspension button can be shown.That is suspension button and suspension button excludes each other out
Existing, it then follows " you show that I hides；You hide, and I shows ".According to a preferred embodiment of the present invention, suspended window can
Arbitrarily dragging, and be suspended on any application, therefore carrier of the suspended window as virtual key is used in the present invention.According to
A preferred embodiment of the present invention, the carrier of virtual key can be otherwise realized, is not necessarily suspended window, can be with
It is suspension button, for example, point one-touch performs the instruction once preset, such as return key.
S402, expansion suspended window, click on the screenshotss function button on suspended window；According to the side of being preferable to carry out of the present invention
Formula, click on after suspension button expansion suspended window further by click on the function button on suspended window select specific function by
Key, such as return key, Menu key, screenshotss key.According to a preferred embodiment of the present invention, carried out exemplified by clicking on screenshotss key
It is described below.
S403, start a sub-line journey, the realization of screenshotss function is carried out in sub-line journey；Pass through new Thread () first
Method creates an anonymous sub-line journey object, then calls start () method of sub-line journey object to be started, then exists
Screenshotss function is performed in sub-line journey.Due to implement screenshotss function need to judge system whether Root；Obtain Root authority；Create
The performing environment of shell-command row；Command verification is carried out in order line；Specific instruction etc. is performed, it is time-consuming longer, in order to
The flow of main thread is not interfered with, it is therefore desirable to its process is put into sub-line journey and performed.Otherwise, once perform the time exceed be
Unite the maximum time born, it will cause main thread without response, the generation using deadlock phenomenon occur for a long time.
S404, judge terminal whether Root；If it is judged that being no, then perform S405, if it is judged that be it is yes, then
Perform S406.The realization of this function needs the support of terminal Root authority.Judge terminal whether Root, generally by detection one
Conventional system directory whether there is su files to realize a bit, such as detection/system/bin/ ,/system/xbin/ ,/
The catalogues such as sbin/ ,/system/sd/xbin/ ,/data/local/xbin/ ,/data/local/bin/ are with the presence or absence of su texts
Part, if there is being considered as terminal Root.According to a preferred embodiment of the present invention, it can also pass through other detection sides
Formula, for example " su " directly is performed in shell instructions, a simple print command is performed in the output system of return, if
Return successfully, then represent Root successes；According to a preferred embodiment of the present invention, can by third-party built-in function come
Detected.
The non-Root of S405, prompt terminal, this function can not be used, continues executing with S4015；When detect the non-Root of terminal into

User goes to carry out terminal Root, such as the address of one download Root instrument of prompting, so as to obtain more preferable Consumer's Experience.
Whether S406, application Root authority, system prompt assign the app authorities, are performed after Root authority application success
S408, when Root authority application is unsuccessful, perform S407.
, it is necessary to get Root authority before specific shell instruction is performed, although terminal Root,
If there is no the mandate using Root authority, failure can be equally performed.According to a preferred embodiment of the present invention, make
Detect whether to assign this app authority with the hasRooted () method in third party library rootmanager_1.5.0.jar, hold
After row hasRooted () method, the rights management of system can be triggered, after only system assigns Root authority, could continue to hold
OK.
Terminal is generally managed after by Root by a Root management tool to the Root authority of system, is being needed
When using Root authority, the Root management tools of system can be all triggered, management tool generally prompts user, if assign Root
Authority, Root authority only could be obtained after confirmation is clicked on, then could perform corresponding function, otherwise can prompted to obtain and weigh
Limit failure.User can also actively assign app authorities into Root management tools, can select to allow, and prompt, and forbid three kinds of behaviour
Make.
S407, Root authority is not obtained, perform failure, continue executing with S4015；Prompt to use if Root authority is not obtained
Family, and exit function.According to a preferred embodiment of the present invention, friendly prompting can be set, guiding user goes to decontrol authority.
The filename of the screenshot picture generated after S408, structure screenshotss success；After Root authority success is obtained, then structure
Build filename corresponding to screenshot picture.
After Root authority is obtained, filename corresponding to screenshot picture is then built.This filename can be as needed
It is defined, according to a preferred embodiment of the present invention, the character string generated with current time after formatting is made
For title, form as similar " yyyy-MM-dd-HH-mm-ss ", yyyy represents the time, and MM represents the moon, and dd represents day, HH
Hour is represented, mm represents minute, and ss represents the second, and it is not in duplication of name phenomenon that the file so generated, which ensures,.It is currently also other
Method, according to a preferred embodiment of the present invention, the filename of random number or timestamp as generation can be used.If
Using formatted. times as filename, then the time of file generated can be known from file name.Then, generation text is obtained
The part path to be saved in, this path can be write extremely in a program, can also be selected by user, be generally directed to SD card
Under some catalogue, such as picture directory, photograph catalogue etc., so it is easy to user to check the figure cut by picture browsing software
Piece.Finally by the path of setting, plus filename, and after " .png " (suffix name, representative are the pictures of png forms) is such
Sew name and be spliced into a complete file name, it includes routing information, file name information, file type information.According to this
One preferred embodiment of invention, similar to "/storage/emulated/0/Pictures/2017-08-16-24-00-
Such a character strings of 00.png ".Wherein "/storage/emulated/0/Pictures/ " is routing information, " 2017-
08-16-24-00-00 " is that file is become famous, and " .png " is suffix name, and representative is the picture of a png form.
S409, the performing environment for creating a shell；Use " su " to be used as parameter, create shell execution ring
Border, Root authority will be asked for system when performing this instruction, because having got Root authority before, here
No longer user is reminded to assign Root authority.Establishment shell-command row performing environment is a more complicated process, it is necessary to first
A Process process is generated, a sub-line journey is then created in process verifies whether it succeeds, after the completion of, pass through one
Whether the further verification command row environment of instruction of entitled " id " is Root environment, then could be used.Specific step is permissible
With reference to figure 6, it is carried out relatively to be described in detail.
S4010, performed in shell environment shaped like " the complete filenames of screencap " such instruction：Creating
After shell environment success, packaged method will be passed through shaped like character string command as " the complete filenames of screencap "
It is delivered in shell execute instruction environment, this instruction is then performed in shell environment, wherein " screencap " system of representatives
The feasibility file of system, it be used for realize screenshotss function, be generally present in system /system/bin catalogues under.It is system
The screenshotss program carried, the java applet being different from, it is a binary executable program, can only be in order line ring
Border is performed, and is realized with C language or C Plus Plus.This perform file do not open to the outside world, only obtain System Privileges or
The application of person's Root authority can just call it, so one of this patent scheme on condition that system must need Root, so
It can call and arrive this executable file.It is upon execution, it is necessary to a parameter-filename, and we have been passed to belt path here
The screenshotss content of generation is saved in this file by filename, so this executable file upon execution, ultimately generates screenshotss text
Part.
The execute instruction in shell environment, according to a preferred embodiment of the present invention, instruction can use shaped like
The character string of " the complete filenames of screencap "；, will be shaped like " screencap is complete after shell environment success is created
Character string command as filename " is delivered in shell execute instruction environment by packaged method, then in shell
This instruction is performed in environment, wherein " screencap " represents the feasibility file of system, it is used for realizing screenshotss function, one
As be present in system /system/bin catalogues under.It is the screenshotss program that system carries, the java applet being different from,
It is a binary executable program, can only be performed in command line environment.This performs file and not opened to the outside world, only
There is the application for obtaining System Privileges or Root authority just to call it, so the premise that the present invention is implemented is that system must need
Root is wanted, could so call and arrive this executable file.It upon execution, it is necessary to a parameter-filename, here we
The filename of belt path has been passed to, the screenshotss content of generation is saved in this file by so this executable file upon execution,
Ultimately generate screenshotss file.
Whether S4011, decision instruction run succeeded；This step, which relies primarily on, judges the return value of implementing result to be located
Reason, if true, represent that order runs succeeded, return to false, expression performs failure.When judged result is no, step is performed
Rapid S4012, when judged result is to be, perform step S4013.
S4012, instruction perform failure, continue executing with S4015；Shell instructions perform failure, will move out program, discharge it
The resource of preceding application, shell processes of establishment etc. are exited, and prompt user's information to malfunction.
S4013, the successful animation of screenshotss file generated is performed, while send a Custom Notification column；Screenshotss file is given birth to
Cheng Hou, meeting file corresponding to generation under specified file directory, but user can not know, can add to improve Experience Degree
Add an animation.For example one screenshotss picture of increase is descending, the animation of the change procedure finally to disappear, such user's sense
Feel that screenshotss are successful, Consumer's Experience will be very good.In addition, in order to allow user to recognize the position that screenshot picture preserves, with
And the position that can be jumped to where file.An informing message can be defined after screenshotss success, be subsequently transmitted to
System, will be in routing information corresponding to informing position display screenshotss file after the notified column message of system, and clicks on
After can jump to position corresponding to picture, will so greatly promote user experience.
S4014, realize screenshotss function；Run succeeded, system can respond the system keypress function of execution.When click screenshotss key

Shield function, use the technology of suspension button and suspended window, and in order to make suspension button and suspended window timely respond to use
Family inputs, and starts a Service process to be managed, and application program is not easy by system or third party's kill.Ginseng
Examine Fig. 5 and illustrate suspension button and suspended window start-up course and workflow.
S501, startup program；Program starts three kinds of situations of entrance point, and one kind is that program just installs success, at this moment automatically
Startup program；Second is that terminal has been mounted with this program, is turned back on, and receives system boot broadcast or other conventional
System broadcast message, such as network change, bluetooth, GPS etc. is switched, the operation of its automatic start will be triggered；The third is user's hand
Dynamic point hits program icon, startup program.
S502, start client process；Program runs client process first after starting, and suspended window is contained in this process
All setting functions and some other miscellaneous function, as theme is replaced, the switches of function items is set, feedback of the information, helped,
The contents such as version information.
S503, by client process start an Android Service process；Generally there are two processes, one is
Client process, one is Service processes, and the former is that some auxiliary of major function are set, and the latter is used for realizing specifically
Function, Service advantage is the backstage for the system that may operate in, and is not easy to be killed, and can be provided persistently with it
Suspended window displaying, improve the Experience Degree of user.
S504, suspension button and suspended window are respectively created in Service processes；The realization of suspension button and suspended window is former
Manage similar, be all the addView methods by the WindowManager (window manager) of system offer in system interface management
A window is added in device, and the priority of this window newly added is arranged to TYPE_SYSTEM_ALERT ranks, so it
Priority it is very high, it is possible to be shown on most systems window, reached " suspension " on other windows
Purpose.
S505, Service process are being always maintained at running from the background, show suspension button, hide suspended window；Sevice processes
An advantage exactly can be always maintained at running from the background, after its starting, during holding state, suspension button is shown
Come, and suspended window is hidden, the relation of both is mutual exclusion, and " you show that I hides；You hide, and I shows ".
S506, judge whether to click on suspension button；Need first to click on suspension button when performing concrete function, suspended window is shown
Show to come.If it is judged that being no, then S507 is performed；If it is judged that being yes, then S508 is performed.
S507, standby operation, continue to monitor key-press event, be back to S505；If not having to click on event, suspension is pressed
Key will keep standby operation, until listening to key-press event.
S508, display suspended window, hide suspension button；Click event is received, suspension button is hidden, and realizes suspension
Window.
The various keypress functions that S509, displaying are supported；Deploy suspended window, the supported institute of displaying is functional, for example, virtually
Return to keypress function.By ViewPager, (a kind of standard control of android system, can horizontally slip the different boundary of switching
Face) control come realize suspended window page function items show, multi-screen content can be shown, switched over by horizontally slipping.
S5010, screen is clicked on, whether the position for judging to click on is virtual functions key on suspended window；Screen is clicked on, is judged
Whether the position of click is function button corresponding to suspended window.If the judgment is Yes, then S5012 is performed；If the judgment is No, then
Perform S5011.
S5011, suspended window is exited, hidden, flex suspension button；If the position clicked on is not certain on suspended window
One button, and be click on blank space, then suspended window is exited, suspended window is closed, opens suspension button, returns to S505；Keep
The standby operation of suspension button, continue to monitor the key-press event of suspension button.As long as not shutting down, suspension button can suspend aobvious always

Whether the button that S5012, judgement currently perform is screenshotss function, if it is judged that being yes, then performs S5013；
If it is judged that being no, then S5014 is performed；Screenshotss function needs the processing that suspension button is hidden and shown, prevents
It influences the result of screenshotss.
S5013, current suspension button is hidden, prevent that suspension button is shown in current screenshotss picture during screenshotss, continued
Perform S5014；According to a preferred embodiment of the present invention, during screenshotss, simply expect current interface content, be not desired to by
In the currently displayed screenshotss interface of suspension button, so needing current suspension button being hidden.According to one of the present invention
Preferred embodiment, if the user desired that it is included in screenshotss interface, user can be given by way of menu is set
Selected, then increasing a switch in screenshotss flow carries out judging whether show or hide.
Function corresponding to S5014, execution；Corresponding keypress function is performed for clicking on.
S5015, function are finished, if performed is screenshotss function, need to show suspension button；
, it is necessary to judge function performed after function is finished, if screenshotss function, then need suspension hiding before
Button is shown, is easy to subsequently be continuing with suspension button, makes program continue to keep standby operation.
S5016, standby operation, continue to monitor key-press event, continue executing with S509；Keypress function is finished, and keeps outstanding
Floating window is shown, continues executing with other functions.The standby operation of suspended window, continue to monitor key-press event.
Above is suspension button and suspended window start-up course and workflow, will be described how to create below has
The shell-command row performing environment of Root authority, and how to realize by this environment the detailed process of screenshotss.Obtaining
, it is necessary to create shell-command row performing environment after Root authority, this establishment process is more complicated, must need to verify that its is correct
Property, screenshotss instruction then could be performed in this environment.Specific execution flow is as shown in Figure 6：
S601, prepare to create shell-command row environment；Will be by the executable file of Root authority and system
Screencap carries out screenshotss, it is necessary to create the command line environment that an executable file is able to carry out, and applies in order line
Root authority, then screencap is called to realize screenshotss.Such a command line environment must be created that first, this environment
It is a Process process in the angle that program is realized, and order line needs inlet flow DataInputStream (java systems
The data input stream of system) and output stream DataOutputStream (data output of java systems), it is used for into line command
Input and the output of implementing result, need first to be created that these to come in the shell classes of establishment.
S602, using system class ProcessBuilder create a Process process, incoming parameter is " su "：By
S601 knows that shell-command row environment is a Process process in fact, and we use system class ProcessBuilder's
Start () method creates such a Process, while parameter " su " passes to class ProcessBuilder construction
Function, represent to order using " su " to create this process.After creating successfully, it should be an order line with Root authority
Environment, its effect are similar to start Windows dos window, and " adb shell " start shell for input wherein
Environment, su instructions are then inputted, it is the same into Root command line execution environments.
S603, start whether sub-line journey checking Process processes create success；According to the side of being preferable to carry out of the present invention
Formula, using " echo Started n " command verification, whether this Process process creates success；Here Thread is started
Thread judges whether this process creates success, according to output stream DataOutputStream (java systems in sub-line journey
Data output), write one " echo Started n " instruction wherein, then obtain the result of its execution, if knot
Fruit is equal to " Started ", illustrates that in this environment be a normal command line execution environment.Here echo is a system
Shell instruction, represent by below character string as former state export.
S604, judge whether there is abnormal generation during checking, if it is judged that being yes, then perform S605；If it is determined that
As a result it is no, then performs S606；, it is necessary to be operated to iostream during checking, it is possible to occur
IO input and output as IOException (one kind of system is abnormal, represents that there occurs abnormal conditions in terms of iostream)
It is abnormal, so needing to capture this kind of exception, if abnormal occur, illustrate to malfunction during checking, the Process of establishment enters
Problem be present in journey；Otherwise represent normal.
S605, shell environment failure is created, perform S6012；Abnormal to occur, the Process processes for illustrating to create, which exist, asks
Topic, shell environment create failure.
S606, instructed using id and further verify whether the shell-command row process context created is a Root environment；
Process processes or the success of shell process creations are determined by above step, but need to determine whether currently whether be in
Under Root patterns or environment.Whether character string uid=0 is included to judge used here as the result that decision instruction id is performed.Wound
Character string command row as building one " id " gives the execution of shell processes, then judges whether implementing result includes " uid=
0 " such character string, if comprising the process for illustrating to create is a process under Root environment.Because order id is to use
To determine the instruction of currently used person's identity, only after system Root, and when being currently at Root environment, can just obtain
Uid is result as 0.
S607, judge whether implementing result is correct；If it is judged that being no, then S605 is performed；If it is judged that it is
It is then to perform S608；Whether judged result is comprising character string as " uid=0 ", if creating one comprising explanation has
The shell environment of Root authority, otherwise illustrate that this shell environment creates failure.
S608, establishment shell order line process context run succeeded；If it is determined that contain the shell of Root authority
Order line process context create successfully, expression can continue executing with screenshotss instruction.
Filename pathName corresponding to the screenshotss file that S609, acquisition create before；Before structure screenshotss instruction, need
Filename corresponding to screenshotss file is first generated and get, the establishment of this filename, which may be referred to Fig. 4, detailed introduction,
Variable pathName is assigned to after acquisition.
S6010, execute instruction " the screencap pathName " in shell-command row；Obtain corresponding to screenshotss file
After filename pathName, creating screenshotss instruction, " screencap pathName ", wherein screencap are the executable of system
Program, for realizing screenshotss, pathName is a string variable, represents the filename of screenshotss file, performs such refer to
After order, the screencap executable programs of calling system are subjected to screenshotss, and the storage of screenshotss content is represented to pathName
In file.
Whether S6011, decision instruction run succeeded, if it is judged that being no, then perform S6012；If it is judged that
It is yes, then performs S6013；Judge whether screenshotss succeed by the return value of instruction execution.
S6012, false is returned to, screenshotss failure, perform S6014；If performing failure, one, upper strata false is returned to
Value.
S6013, true is returned to, screenshotss success, perform S6014：If run succeeded, one, upper strata true is returned to
Value.
S6014, exit, return to implementing result；The result performed is returned to, upper strata receives return value, determined according to return value
Whether continue down to perform.
Two hands of user are needed in screenshotss while two Macintosh of long-press system could be real for intelligent terminal user
Existing screenshotss, this is used for the unskilled user of intelligent terminal for some, it will it is difficult to operate；And some users are at all
Also such function is not known, can also be done by screenshotss.In addition, entity key is after a long time use, also frequently
There is the problem of insensitive or failure.The present invention proposes a kind of method of solution.First, screenshotss function has been transplanted to one
On individual virtual key, being achieved that as long as clicking on, the scheme that than two hands press two systems button simultaneously is more convenient,
Everybody can operate, in addition, because virtual key has explanatory note, user is also very easy to find this function；Secondly, for a long time
