Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 1, a flowchart illustrating steps of embodiment 1 of a method for performing screen capture in a mobile terminal according to the present invention is shown, which may specifically include the following steps:
step 101, when a screen capture request is received in a mobile terminal, searching first picture data representing a user head portrait in a current interface;
it should be noted that the embodiment of the present invention may be applied to a mobile terminal, for example, a mobile phone, a tablet computer, a smart watch, and the like, and the embodiment of the present invention is not limited thereto.
The operating systems of these mobile terminals may include Android (Android), IOS, Windows Phone, and the like, and may generally support communication tools of third parties for communication, such as instant messaging tools, mailbox clients, microblog applications, forum applications, and the like.
Under the condition that a User intends to show conversation contents of communication performed by a communication tool of a third party and the like, the User can trigger screen capture operation and send a screen capture request to the system, and then the system can search first picture data representing a User avatar in a current UI (User Interface).
It should be noted that the screen capturing operation in the embodiment of the present invention may refer to anonymous screen capturing, that is, screen capturing after anonymous processing of the user name and the user avatar.
The anonymous screen capture can be controlled through a separate screen capture entry or an option of an anonymous screen capture switch in the device.
Of course, the embodiment of the invention can also provide non-anonymous screen capture, namely normal screen capture, and retain the user name and the user head portrait.
In one embodiment of the present invention, step 101 may comprise the following sub-steps:
a substep S11, searching the view group at the topmost layer in the current interface;
as shown in fig. 2A, in the Android system, each display control in the UI interface is inherited to View (View), and the ViewGroup is a container for accommodating the controls.
A control container class ViewGroup may also contain View and ViewGroup.
A complex UI may include multiple views and viewgroups that form a hierarchy in the layout.
In one example, the UI interface shown in fig. 2B performs maintenance and control of each spatial display process through a view hierarchy data structure shown in fig. 2C in the Android system.
In FIG. 2C, controls such as TextView and ImageView are inherited to View, and FrameLayout, LinearLayout and RelativeLayout are inherited to ViewGroup.
Note that ViewGroup is also inherited to View.
Further, in the Android system, the topmost window of the application is called decoview, which is derived from FrameLayout, which is derived from ViewGroup, and therefore, the topmost window mentioned in the present invention is referred to as decoview.
When an application program creates a display window, a DecorView object is created in advance, and when the DecorView is created, a BroadcastReceiver is registered to receive a screen capture request of a user.
When a user triggers screen capture, a screen capture broadcast is sent to the DecorView, and the DecorView receives the broadcast and then redraws a window.
Substep S12, traversing the view group, and finding a picture view;
in a specific implementation, the ImageView (picture view) is generally used for displaying pictures, that is, candidate picture data is in the picture view, and therefore, the user head portrait data in the current UI interface is in one or more of the imageviews.
And a substep S13 of determining the candidate picture data as first picture data representing the avatar of the user when the position of the candidate picture data matches the position of preset avatar data of the user.
By applying the embodiment of the invention, the position of the head portrait data of the user can be obtained in advance and stored in the database.
In one example, since the user avatar data that is simultaneously communicated is usually loaded through ImageView in the session, that is, the user avatar is loaded on the current display interface through a fixed control, the position of the user avatar data may be obtained by obtaining the position of the control corresponding to the ImageView.
Further, if the third-party application provides operations such as marking and forwarding, the user may manually copy the user avatar data, and if not, the user may also manually select the user avatar data.
Of course, the specification of the UI interface of the third-party application is relatively stable for a certain period of time except for the user copying and selecting, so that the user avatar data can be read from a specific location together with the specification of the UI interface, and the like, which is not limited by the embodiment of the present invention.
When the user head portrait is identified, the user head portrait data can be read from the database, and if the candidate picture data of the ImageView is matched with the user head portrait data, the candidate picture data of the ImageView can be represented as a user name.
Furthermore, because the specification of the UI interface of the third-party application is relatively stable within a certain period of time, the user avatar data can be read from a specific position together with the specification of the UI interface, that is, when the user avatar is identified, if the position information corresponding to the candidate picture data of the ImageView matches the position information corresponding to the user avatar data in the UI interface of the third-party application, the candidate picture data of the ImageView can be represented as the user avatar.
For example, as shown in fig. 2D, the current display interface includes ImageView a, TextView B, ImageView C, and TextView D, where according to the specification of the UI interface of the third-party application, the user avatar data is loaded through ImageView a and ImageView C, that is, the picture data loaded by ImageView a is the avatar corresponding to user a, and the picture data loaded by ImageView C is the avatar corresponding to user C, so that the position information of the user avatar data of the current display interface can be obtained by obtaining the position information of ImageView a and ImageView C, or the picture data loaded by ImageView a and ImageView C is directly determined as the first picture data representing the avatar of the user.
Step 102, replacing the first picture data with preset second picture data;
in the embodiment of the invention, before screenshot, anonymization processing can be performed on the user avatar of the current UI, that is, first picture data representing the user avatar is replaced by second picture data not representing the user avatar.
For example, the second picture data may be a plant picture as shown in fig. 3C and an animal picture as shown in fig. 3D, and so on.
In an alternative, all of the first picture data may be replaced with the same second picture data, such as replacing all of the user's head with "■ ■ ■".
In another alternative, the individual first picture data may be identified and replaced with the individual second picture data.
So-called individual, i.e., single, independent, there are no repetitions.
For example, if the user head portraits in the current UI interface are respectively the user head portraits corresponding to "three-piece" and "four-piece", the user head portraits corresponding to "three-piece" of the user may be replaced by the plant picture shown in fig. 3C, the user head portraits corresponding to "four-piece" of the user may be replaced by the animal picture shown in fig. 3D, and so on.
In one embodiment of the present invention, step 102 may include the following sub-steps:
substep S21, measuring, laying out and drawing the picture view to which the first picture data belongs again, and replacing the first picture data with preset second picture data during drawing;
and a substep S22 of re-measuring, laying out and drawing the target view.
The target view is a view in the view group except the picture view to which the first picture data belongs, and the target view includes a picture view and a text view.
The process of displaying the UI interface by the system is actually a process of performing traversal measurement (measure), layout (layout), and drawing (draw) for each View, starting from the outermost View group.
The measurement (measure) is mainly used for determining the size of the control View, the actual size of the entire View tree is calculated, namely the actual height (corresponding attribute: mMeasuredHeight) and width (corresponding attribute: mMeasureWidth) are set, and the actual width and height of the control of each View are determined by the parent View and the own View.
The specific call chain is as follows:
the attribute mView (the type of the mView is a ViewGroup type generally) of a ViewRoot root object calls a measure () method to calculate the size of a View tree, and calls back an onMeasure () method of the View/ViewGroup object, wherein the method realizes the following functions:
1. setting the final size of the View, and realizing the function, setting the actual height (corresponding attribute: mMeasuredHeight) and width (corresponding attribute: mMeasureWidth) by calling a setMeasuredDimension () method;
2. If the View object is a ViewGroup type, the method of the onMeasure () needs to be rewritten, and the measure () process of traversing the child View is needed.
2.1 the measure () process of each sub-View is realized by calling the measure containment within the java class of the parent View group, because the measure containment within the map storage () process is a transition layer simpler process of directly calling the measure () process of the View object, the process simply calls the measure () process of the View object.
And (4) layout (layout) mainly determines the position of the control View, and the entire View tree is put on a proper position according to the size of the sub-View and the layout parameters.
The specific call chain is as follows:
lay () starts the layout of the View tree and then calls back to the lay () method in the View/View group class. The specific process is as follows:
1. The layout method sets the View to be located on the coordinate axes of the parent View, namely mLeft, mTop, mLeft, mBottom (call setFrame () function to implement);
next, the onLayout () method is called back (if the View is the ViewGroup object, the method needs to be implemented, and each sub-View is laid out).
2. If the View is a ViewGroup type, it is necessary to traverse each child View and call the layout () method of the child View to set its coordinate values.
Rendering (draw) primarily determines the display of the control View.
Calling a draw () method by a performTraversals () method of a Viewroot object to initiate drawing of the View tree, and noteworthy that when drawing is initiated each time, the View of each View tree is not redrawn, but only the views which need to be redrawn are redrawn, wherein a View class internal variable comprises a flag bit DRAWN, and when the View needs to be redrawn, the flag bit is added to the View.
The calling process is as follows:
draw () starts drawing, and the draw () method implements the following functions:
1. Drawing a background of the View;
2. Preparing to display the gradual change frame;
3. invoking the onDraw () method to draw the View itself (each View needs to reload the method, the ViewGroup does not need to implement the method);
4. calling the dispatchDraw () method to draw a child View (if the View type is not ViewGroup, i.e., does not contain a child View, the method does not need to be reloaded);
it should be noted that the ViewGroup class has rewritten the function implementation of dispatcdraw () for us, and the application program generally does not need to rewrite the method, but can reload the parent class function to implement the specific function.
4.1 DispatchDraw () method internally traverses each child view, calling Drawchild () to recall the draw () method of each child view (note that this place the "redrawn needed" view will call the draw () method).
It should be noted that the ViewGroup class has rewritten the function implementation of the dispatchDraw (), and the application program generally does not need to rewrite the method, but may reload the parent function to implement the specific function.
5. Drawing a scroll bar.
In the embodiment of the invention, after the topmost ViewGroup receives the screen capture request, each sub-View or sub-ViewGroup can be traversed to perform re-measurement, layout and drawing.
The redrawing is started from the DecorView, and all the sub-views or sub-Viewgroups can be guaranteed to have an opportunity to be redrawn, so that the interface of the whole application program is redrawn, all the anonymously displayed character strings can be guaranteed to be updated and drawn, and the problem of incomplete replacement of the first picture data is solved.
In the Android system, picture data calls canvas.
And storing second picture data to be drawn currently before the DrawText function is executed, filtering and replacing the first picture data according to a preset character string filtering mode, generating new second picture data to be displayed after filtering and replacing are finished, and calling the DrawText function to draw a new display character string.
And 103, performing screen capturing operation on the interface after the second picture data is replaced according to the screen capturing request.
When the mobile terminal captures the screen, a screen capturing broadcast is sent to the DecorView, the DecorView receives the broadcast, redraws the topmost ViewGroup, and sends the redrawn to the SurfaceFlinger or other modes for screen capturing.
The surfefinger discloses a screen capture interface, which may directly perform screen capture, or may perform screen capture through other ways, for example, a manner of directly reading a frame buffer or a manner of reading a gpu image buffer, which is not limited in this embodiment of the present invention.
In an application scenario, as shown in fig. 3A, in a group, a user with the user name "wang jian epi" prompts that an elevator is dangerous, and the current user wants to capture a screen to tell other users, as shown in fig. 3B, when capturing the screen, head images corresponding to the user names "wang jian epi" and "zhangzhi" are respectively replaced by pictures shown in fig. 3C and 3D, and meanwhile, the user names "wang jian epi" and "zhangzhi" are replaced by "■ ■ ■", so that anonymous screen capture is realized, and privacy safety of the user is ensured.
According to the embodiment of the invention, the first picture data representing the user name is replaced by the preset second picture data, and then screen capturing is carried out, so that the privacy of the user is protected, meanwhile, a special picture editing tool is prevented from being used for manual smearing, the technical threshold of anonymous processing is greatly lowered, the error probability is lowered, and the quality of anonymous modification is improved.
Referring to fig. 4, a flowchart illustrating steps of embodiment 2 of a method for performing screen capture in a mobile terminal according to the present invention is shown, which may specifically include the following steps:
step 401, when a screen capture request is received in a mobile terminal, searching first picture data representing a user head portrait in a current interface;
step 402, replacing the first picture data with preset second picture data;
step 403, performing screen capture operation on the interface after replacing with the second picture data according to the screen capture request;
and step 404, replacing the second picture data with the first picture data when the screen capture is finished.
In a specific implementation, the screen capture call is a synchronous interface, and the screen capture end is indicated by the return of the interface call.
If the screen capture is finished, the second picture data can be replaced by the first picture data, and the normal operation of the application program is ensured.
In one embodiment of the present invention, step 404 may include the following sub-steps:
substep S31, measuring, laying out and drawing the picture view to which the second picture data belongs again, and replacing the second picture data with the first picture data during drawing;
a substep S32 of re-measuring, laying out and drawing the target view;
wherein the target view is a view in the view group except for the picture view to which the first picture data belongs.
In the embodiment of the invention, after the topmost View group receives the broadcast of which the screen capturing is finished, each sub View or sub View group can be traversed to carry out re-measurement, layout and drawing.
And starting redrawing from the DecorView, which can ensure that all the sub-views or sub-Viewgroups have an opportunity to redraw, therefore, the interface of the whole application program is redrawn, all the anonymously displayed character strings can be ensured to be updated and drawn, and the problem of incomplete data replacement of the second picture is avoided.
In the Android system, picture data calls canvas.
And storing the first picture data to be drawn before the DrawImage function is executed, filtering and replacing the second picture data according to a preset picture filtering mode, generating new first picture data to be displayed after filtering and replacing are finished, and calling the DrawImage function to draw a new display character string.
It should be noted that each ImageView has its own instance in the memory, and the instances are isolated from each other and will not affect each other.
Therefore, the first picture data to be held by each ImageView may be saved in one member variable of the instance itself.
It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention. Further, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred and that no particular act is required to implement the invention.
