Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
In order to avoid information leakage of a user, a possible solution is to capture a screenshot of a current display interface and cover a fuzzy masking layer on the screenshot, so that when the user views a background running application, the screenshot covered with the fuzzy masking layer corresponding to the displayed application program is a full-range shielding mode. However, this approach has at least the following disadvantages: when a user switches an application to another application and operates the other application, the user may need to check information in an interface before the application is switched to a background, but the user cannot check the information due to the shielding of the fuzzy masking layer, so that inconvenience is brought to the user, and the full-range shielding mode is not flexible; moreover, because of the full range of masking, strangers' curiosity can be caused, and the risk that privacy is over-concerned and stolen can be increased. Based on this, the embodiment of the present invention provides a background display method for an application program, so as to overcome the disadvantages of the above solutions.
Fig. 1 is a flowchart illustrating a background display method for an application according to an embodiment of the present invention, where as shown in fig. 1, the method includes the following steps:
step S101, responding to a background operation switching instruction aiming at the application, and generating a background operation state identifier.
Illustratively, when the application runs in a foreground, a user executes a first gesture from top to bottom on a terminal screen so as to switch the application to a background operation, detects a first sliding gesture executed by the user, and generates a background operation switching instruction for the application. Of course, the trigger operation for switching the application to the background running is not limited to this.
In response to the background running switching instruction for the application, a background running state identifier is generated, at this time, the application does not run in the background, the background running state identifier does not represent the real running state of the application, but is equivalent to a signal, and after receiving the signal, the processing program performs the occlusion processing on the private information, which will be described in detail later.
Step S102, traversing each interface element in the current display interface of the application, and obtaining the attribute label of each interface element.
The interface elements refer to information types displayed in the interface, and take an electronic book application as an example, the interface elements of the electronic book application include: user ID, user account, reading duration, membership grade, external import book file, user comment, user idea, and the like.
Traversing each interface element in a current display interface of the application, and obtaining an attribute tag of each interface element, where the attribute tag of the interface element may be set by default by the system, or may be set manually by a user, for example, the user may manually set the attribute tag of the interface element corresponding to information (such as user privacy information) that the user thinks it needs to be hidden as a privacy tag.
And step S103, according to the background running state identification, drawing a hidden cover layer on a display area of the interface element of which the attribute tag is the privacy tag in the current display interface to obtain a shielded display interface.
The attribute tag is an interface element of the privacy tag, that is, an interface element which needs to be hidden, that is, a privacy interface element. For interface elements that do not need to be hidden, the attribute tag may be set as a non-privacy tag, or the attribute tag may not be set, and interface elements that do not have attribute tags are interface elements that do not need to be hidden by default, which is not limited in the present invention.
In this embodiment, according to the generated background running state identifier, the blocking processing of the private information is performed before the application is switched to the background. Specifically, the interface element of which the attribute tag is the privacy tag in the current display interface is determined, the hidden masking layer is drawn on the display area of the interface element of which the attribute tag is the privacy tag, the masked display interface is obtained, the display area of the privacy interface element is masked by the fuzzy masking layer through the step, and information displayed in the display area is also masked.
And step S104, performing screenshot processing on the shielded display interface to obtain a screenshot of the shielded display interface corresponding to the application.
And performing screenshot processing on the shielded display interface, wherein the display area of the interface element which needs to be hidden in the obtained screenshot is shielded, and the display areas of other interface elements which do not need to be hidden are not shielded.
And step S105, switching the application to the background operation.
And after screenshot is carried out on the shielded display interface, switching the application to the background to run.
And S106, responding to a viewing instruction of the background running application, and displaying a screenshot of a shielded display interface corresponding to the background running application.
Illustratively, the user performs a second gesture from bottom to top on the terminal screen to view the application running in the background, and when the second gesture is detected, a viewing instruction of the application running in the background is generated.
And responding to a viewing instruction of the background running applications, and displaying the screenshots of the shielded display interfaces corresponding to the background running applications.
Therefore, a certain delay exists between the background running switching instruction for the application is received and the application is switched to the background running, and the method of the embodiment is to perform processing of drawing the shielding cover layer and screenshot for the interface element which needs to be hidden in the display interface of the application during the delay.
In summary, different from the above full-range blocking manner, the manner of this embodiment is to draw the fuzzy masking layer on the area to be hidden specified in the display interface, for example, the area to be hidden may be set as a display area of the user privacy information, so that the display area of the user privacy information may be blocked by the manner of this embodiment, and leakage of the user privacy information may be avoided; compared with a full-range shielding mode, the mode of the embodiment has higher flexibility, and is convenient for a user to check information in a display interface before the application is switched to the background operation; meanwhile, compared with a full-range shielding mode, the method is also beneficial to reducing the risk of stealing the user information.
According to the background display method of the application program, after a background switching instruction for the application is received, firstly, a privacy interface element in a current display interface is determined, a hidden cover layer is drawn on a display area of the privacy interface element to shield privacy information, then, screenshot is conducted on the shielded display interface, finally, the application is switched to background operation, and when a user views the background operation application, the screenshot of the shielded display interface is displayed. In the background display method of the application program provided by the embodiment, the generated hidden mask layer shields the specified information to be hidden, and compared with a full-range shielding mode, the background display method has higher flexibility, is convenient for a user to view the information not to be hidden, and can also avoid the problem of user information leakage caused by background operation switching.
Fig. 2 is a flowchart illustrating a background display method for an application according to another embodiment of the present invention, where as shown in fig. 2, the method includes the following steps:
step S201, creating a View for drawing the hidden mask layer, and enabling the View of each interface element in any display interface of the application to inherit the View for drawing the hidden mask layer.
The method comprises the steps of creating a View for drawing a hidden masking layer, such as the View for drawing a Gaussian fuzzy masking layer, and then enabling the View of each interface element to inherit the View for drawing the hidden masking layer.
And S202, checking an externally transmitted privacy text identifier in the View for drawing the hidden masking layer, and recording an attribute tag of an interface element corresponding to the privacy text identifier as a privacy tag.
And the View for drawing the hidden masking layer can automatically check the privacy text identification transmitted from the outside, and after the privacy text identification is detected, the attribute tag of the interface element corresponding to the privacy text identification is recorded as the privacy tag.
The method comprises the steps of firstly determining a privacy text identifier, wherein the privacy text identifier can be obtained according to manual setting of a user, and specifically, privacy setting operation is executed according to a text identifier corresponding to any interface element by the user to obtain the privacy text identifier. For example, a "privacy mark" control is provided in the application, the text identifier corresponding to the interface element is a "user name", and the user clicks the "privacy mark" control corresponding to the text identifier- "user name", that is, performs privacy setting operation on the text identifier, and records the text identifier- "user name" as a privacy text identifier. Or the private text identifier may also be obtained by default setting of the system, and the system determines the text identifiers of the interface elements of the private information according to a predetermined rule and sets the text identifiers as the private text identifiers.
The method of the embodiment can be applied to electronic book applications, and when the method is applied to the electronic book applications, the method further comprises the following steps: the attribute tag of the interface element corresponding to the user privacy information in the electronic book application is set as the privacy tag, and the specific embodiment refers to the above description, which is not repeated herein. Automatically setting an interface element attribute tag corresponding to user privacy information in electronic book application as a privacy tag, wherein the user privacy information is as follows: the method comprises the following steps of reading duration information of a user, account information of the user, externally imported book or file information, and privacy comments or ideas of the user.
After a background switching instruction for an electronic book application is received, firstly, privacy tags of interface elements in a current display interface are obtained, and if the display interface comprises the interface elements- "user account", the interface elements- "external import book", and the interface elements- "user privacy comment or idea" … …, a hidden cover layer is drawn on a display area of the interface elements by using the View of the interface elements- "user account", so that the user account information is shielded due to specific information of the user account displayed in the display area, and the processing mode for other interface elements is similar and is not repeated.
Step S203, generating a background running state identifier in response to the background running switching instruction for the application.
And generating a background running state identifier in response to a background running switching instruction for the application, wherein the application does not run in the background, and the background running state identifier does not represent the real running state of the application but is equivalent to a signal used for drawing the hidden layer View and then carrying out shielding processing on the privacy information after receiving the signal.
Step S204, traversing each interface element in the current display interface of the application, and acquiring the attribute label of each interface element.
And S205, providing the background running state identifier for the View corresponding to each interface element in the current display interface, so that the View corresponding to the interface element with the attribute tag as the privacy tag draws a hidden mask layer, and a shielded display interface is obtained.
The interface element of which the attribute tag is a privacy tag is the interface element which needs to be hidden and is set by the user. And transmitting the background running state identification to the View corresponding to each interface element in the current display interface, and drawing a hidden mask layer for the View corresponding to the interface element of the attribute label, so that the display area of the interface element is shielded by the hidden mask layer to obtain a shielded display interface.
And step S206, performing screenshot processing on the shielded display interface to obtain a screenshot of the shielded display interface corresponding to the application.
And performing screenshot processing on the shielded display interface, wherein the display area of the interface element which needs to be hidden in the obtained screenshot is shielded, and the display areas of other interface elements which do not need to be hidden are not shielded.
And step S207, switching the application to background operation.
And after the shielded display interface is subjected to screenshot, formally switching the application to a background to run.
And S208, responding to the viewing instruction of the background running application, and displaying the screenshot of the shielded display interface corresponding to the background running application.
And when the user views the applications running in the background, displaying the screenshots of the shielded display interfaces corresponding to the applications running in the background.
Step S209, in response to the foreground operation switching instruction for the background operation application, generates a foreground operation status identifier.
Illustratively, a user may execute a trigger operation of switching a background running application to a foreground running application through an entry in a blocked display interface corresponding to the background running application. Or, the user may also execute the trigger operation of switching the background running application to the foreground running through the application icon corresponding to the background running application.
When one application is switched to the background operation and then switched to the foreground operation, the display interface to be displayed is consistent with the display interface displayed before the application is switched to the background operation. In this embodiment, the display interface before the application is switched to the background operation is covered with the hidden cover layer, and therefore, when the application is switched to the foreground operation again in the background operation, the drawn hidden cover layer needs to be removed.
Specifically, in response to a foreground running switching instruction for a background running application, a foreground running state identifier is generated, and similarly, the foreground running state identifier does not represent a real running state of the application, but is equivalent to a signal, and the View for drawing the hidden layer performs processing of removing the hidden layer after receiving the signal.
And step S210, providing the foreground running state identification for the View corresponding to each interface element in the shielded display interface of the background running application, so that the View corresponding to each interface element in the shielded display interface can remove the drawn hidden mask layer.
And then, providing the foreground running state identification for the View corresponding to each interface element in the shielded display interface of the background running application, so that the View corresponding to each interface element can remove the previously drawn hidden cover layer. Optionally, in a processing process of switching the application to the background operation, recording the View corresponding to the interface element of the drawn hidden mask layer, and in this step, providing the foreground operation state identifier to the recorded View corresponding to the drawn hidden mask layer.
Step S211, the background running application is switched to the foreground running.
And after the hidden masking layer in the shielded display interface of the background running application is removed, formally switching the background running application to the foreground running.
Similarly, there is a certain delay between receiving the foreground running switching instruction for the background running application and the background running application being switched to the foreground running, and the method of this embodiment is to perform processing of removing the drawn hidden masking layer during this delay.
Fig. 3a shows a schematic diagram of background display of an application program in the prior art, as shown in fig. 3a, in the prior art, a fuzzy masking layer is used to completely shield a screenshot of a whole display interface, after an application is switched to background operation, when a user views the application program running in the background, the screenshot which is shielded in a full range is displayed, and it is assumed that the user needs to view information in the display interface when using other applications, and only the application running in the background can be switched to foreground operation to view the information.
Fig. 3b shows a schematic diagram of background display of an application program in the embodiment of the present invention, as shown in fig. 3b, in the embodiment of the present invention, only a specified area is blocked, for example, display areas of interface elements "my account" and "my card coupon" in fig. 3a are blocked, while display areas of other interface elements are not blocked, in the above scenario, a user only needs to perform a viewing operation of running an application in the background to view non-private information, which is convenient for the user, and meanwhile, it is also ensured that private information is not leaked.
According to the background display method of the application program provided by the embodiment of the invention, the View used for drawing the hidden mask layer is created, so that the View of each interface element of the application inherits the View used for drawing the hidden mask layer, the View of each interface element of the application can draw the privacy mask layer, and the method of the embodiment is easier to implement. In the mode, the user can set the information and the interface elements which need to be hidden by himself, and the method has high flexibility. After the system receives an instruction for switching the application to background operation, firstly, the attribute tag is used as the View of the interface element of the privacy tag to draw the hidden masking layer, so that the information to be hidden is shielded, then, the shielded interface is subjected to screenshot, and then, the application is switched to background operation. And when an instruction for switching the background application to the foreground operation is received, removing the drawn privacy mask layer in the shielded interface, and ensuring the normal operation of the application.
