The target function includes an image scanning function or an image generating function in the first application, and a function that can be realized by a second application having an association relationship with the first application may be determined as the target function according to a preset rule. Specifically, when the second application is a camera application that can be used for shooting, the target function may be determined to be an image scanning function; when the second application is an album application that can be used to store images, then the target function may be determined to be an image generation function.
And 102, calling the first application to execute the operation corresponding to the target function.
In this step, the associated operation is received, the target function associated with the second application is determined, and the first application is called to execute the operation corresponding to the target function, so that compared with the prior art in which the target function is realized by clicking layer by layer, the operation steps can be effectively simplified, the operations of starting the first application and selecting the corresponding function icon can be omitted, and the realization of the target function is more convenient.
If the target function is an image scanning function, starting a camera and displaying an image scanning interface of the first application; if the target function is an image generating function, the two-dimensional code image of the first application may be generated based on preset information of the first application, and the two-dimensional code image may be displayed.
In a specific implementation manner of the embodiment of the present invention, in a process of performing quick payment by using a first application, a user needs to start a two-dimensional code scanning interface of the first application, and in the prior art, the user needs to start the first application first and then click a code scanning icon in the first application to enter the two-dimensional code scanning interface of the first application.
By adopting the operation method provided by the invention, the association operation for associating the first application with the second application is received. In this embodiment, the second application is a camera application, wherein the second application may also be another application that can call a camera for shooting. The method comprises the steps of determining that a target function is an image scanning function, calling the first application to execute and start a camera, displaying an image scanning interface of the first application, and scanning a two-dimensional code image to realize quick payment.
In another specific implementation manner of the embodiment of the present invention, in a process that a user uses a first application to perform quick payment, the user is required to display a two-dimensional code payment receiving image of the first application, and in the prior art, the user is required to start the first application first, and then click a payment receiving icon in the first application to display the two-dimensional code payment receiving image of the first application.
By adopting the operation method provided by the invention, the association operation for associating the first application with the second application is received. In this embodiment, the second application is an album application, and the second application may be another application that can store and display images for shooting. The method comprises the steps of determining a target function as an image generation function, calling the first application to execute the operation of generating and displaying a two-dimensional code payment image of the first application, displaying the two-dimensional code payment image, and enabling other users to scan the two-dimensional code payment image, so that quick collection is achieved.
It should be noted that the image scanning function includes functions of scanning a two-dimensional code, scanning a barcode, scanning a cover, scanning a street view, scanning a translation, and the like, and the functions that can be realized by the image scanning function are not limited thereto, and are not described in detail herein. The image generation function includes functions of generating a merchant payment code, generating a two-dimensional code collection code, generating a personal name card, and the like, and the functions that the image generation function can realize are not limited thereto and are not described in detail herein.
It should be further noted that, an application corresponding to the target function may be preset, for example, for the image scanning function, an association relationship between the first application and the camera application may be preset; for the image generation function, the association relationship of the first application for the album application may be preset. In this way, after receiving the association operation for associating the first application with the camera application, the first application can be directly called to execute the operation of starting the camera and displaying the image scanning interface of the first application; and after receiving the association operation for associating the first application with the album application, directly calling the first application to execute the operation of generating and displaying the two-dimensional code payment image of the first application. By presetting the association relationship between the first application and the camera application or the album application, the determination process of the target function can be omitted, and the time required for executing the operation corresponding to the target function can be saved.

According to the operation method of the mobile terminal, if the association operation for associating the application icon of the first application with the application icon of the second application is received, the target function associated with the second application is determined, wherein the target function comprises an image scanning function or an image generating function in the first application; and calling the first application to execute the operation corresponding to the target function. Therefore, the association relationship between the first application and the second application is established, and the shortcut entry associated with the target function is called according to the association relationship so as to execute the operation corresponding to the target function, so that the operation steps required for executing the target function can be effectively simplified.
Referring to fig. 2, fig. 2 is a flowchart of an operation method of a mobile terminal according to another embodiment of the present invention, as shown in fig. 2, including the following steps:
step 201, if a dragging operation of at least one of the application icon of the first application and the application icon of the second application is received, detecting whether an overlapping area of the application icon of the first application and the application icon of the second application is larger than a preset overlapping area.
In this step, the dragging operation on the application icon of the first application may be a dragging operation of directly dragging the application icon of the first application onto the application icon of the second application, and determining whether the application icon of the second application and the application icon of the first application have an association relationship by detecting whether an overlapping area of the application icon of the first application and the application icon of the second application is larger than a preset overlapping area; in the process of dragging the application icon of the first application, whether an application icon of a second application with an overlapping area larger than a preset overlapping area with the application icon of the first application exists or not may be detected. If yes, go tostep 202; if not, the detection is continued, or the flow is directly ended.
Wherein the preset overlapping area may be set to the icon area 2/3 of the second application or to 3/4 of the icon area of the second application. Of course, the setting of the preset overlapping area is not limited to this, and may be determined specifically according to the actual situation, and is not described herein any more.
Step 202, if the overlapping area of the application icon of the first application and the application icon of the second application is larger than a preset overlapping area, determining that the dragging operation is an association operation for associating the application icon of the first application and the application icon of the second application.
Step 203, responding to the association operation, and determining a target function associated with the second application.
In this step, the target function may be determined according to the category of the second application or the function that the second application can implement.
The target function is a function in the first application, and comprises an image scanning function or an image generating function.
Optionally,step 203 may further include: if the second application is an application which can call a camera for image acquisition, determining that the target function is the image scanning function; and if the second application is an application capable of storing and displaying an image, determining that the target function is the image generation function.
In this embodiment, the target function is determined by the function that can be realized by the second application, so that the shortcut entry associated with the target function is called by the second application, so as to execute the operation corresponding to the target function.
For example, when the second application is a camera application, the target function may be determined to be an image scanning function; when the second application is an album application, then the target function may be determined to be an image generation function.
It should be noted that, when the second application has both the image scanning function and the image storage function, after receiving the association operation for associating the application icon of the first application with the application icon of the second application, the interface is displayed to display the icon option corresponding to the image scanning function and the icon option corresponding to the image storage function for the user to select, and the target function is determined based on the selection of the user. The priorities of the image scanning function and the image storage function may also be set in advance, for example, when the priority of the image scanning function is higher than that of the image storage function, when the second application is used as the associated application, the target function is determined to be the image scanning function; and similarly, when the priority of the image scanning function is lower than that of the image storage function, and the second application is used as the associated application, the target function is determined to be the image storage function, wherein the setting of the priority can be set according to the preference or the actual situation of the user.
And step 204, calling the first application to execute the operation corresponding to the target function.
In this step, the associated operation is received, the target function associated with the second application is determined, and the first application is called to execute the operation corresponding to the target function, so that compared with the prior art in which the target function is realized by clicking layer by layer, the operation steps can be effectively simplified, the operations of starting the first application and selecting the corresponding function icon can be omitted, and the realization of the target function is more convenient.
If the target function is an image scanning function, starting a camera and displaying an image scanning interface of the first application; and if the target function is an image generation function, generating a two-dimensional code image of the first application based on the preset information of the first application, and displaying the two-dimensional code image.
Optionally, afterstep 204, the method further includes: after the target function is executed, if a preset operation of exiting the target function is received, switching the first application from a display interface corresponding to the target function to a preview interface, wherein the preview interface is an interface displayed by the mobile terminal before receiving an association operation of associating the first application with the second application.
In the embodiment, after exiting from the display interface corresponding to the target function, the interface displayed by the mobile terminal before the association operation associating the first application with the second application is directly switched, so that the user can be helped to quickly return to the previous operation interface, and the user operation can be effectively simplified compared with layer-by-layer clicking.
Specifically, in the process of using the first application, for example, in the process of browsing an article or chatting by using the first application, when the first application needs to be used for payment scanning, in the prior art, the current browsing interface or the chatting interface is generally exited, the main interface of the first application is entered, then the scanning icon displayed on the main interface is clicked, the scanning interface is entered, the operation is cumbersome in the whole process, the current display interface is exited, and for some uninterruptible transactions, for example, sudden interruption may cause bad effects. By adopting the operation method provided by the invention, the mobile terminal can return to the desktop, then the application icon of the first application is dragged to the application icon of the camera application, the incidence relation between the first application and the camera application is established, then the first application is called to execute and start the camera according to the incidence relation, the operation of scanning the code interface of the first application is displayed, the payment is completed, and after the payment is completed, the previous display interface can be directly jumped to by clicking the return key.
According to the operation method of the mobile terminal, if dragging operation on at least one application icon of the application icons of the first application and the second application is received, whether the overlapping area of the application icon of the first application and the application icon of the second application is larger than a preset overlapping area or not is detected; if the overlapping area of the application icon of the first application and the application icon of the second application is larger than a preset overlapping area, determining that the dragging operation is an associated operation for associating the application icon of the first application with the application icon of the second application; determining a target function associated with the second application in response to the associating operation; and calling the first application to execute the operation corresponding to the target function. Therefore, the association relationship between the first application and the second application is established, and the shortcut entry associated with the target function is called according to the association relationship so as to execute the operation corresponding to the target function, so that the operation steps required for executing the target function can be effectively simplified.
