Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to solve the technical problem that in the prior art, the application thin client in the Android system only can use the default setting of a mouse pointer, so that the operation convenience is insufficient, in one embodiment, a method for setting a mouse display state in the application thin client and a method for redrawing a mouse pattern in the application thin client are particularly provided. The above method is performed on the basis of a computer program which is executable on a computer device based on the von neumann architecture with the Android system as operating system. The computer equipment can be Android equipment such as an Android TV box and an Android TC box which can be connected with a mouse.
In the method for setting the mouse display state in the application thin client and the method for redrawing the mouse pattern in the application thin client, as shown in fig. 2, the Android device can receive a message or a command issued by a cloud office application or other cloud applications operated by a server on a cloud service platform, and the message or the command is analyzed through an SDKAPI on the Android device, so that the operations of displaying a mouse pointer on a display terminal and hiding the mouse pointer or redrawing the mouse pointer are realized.
Specifically, as shown in fig. 3, the method for setting a mouse display state in an application thin client includes:
step S102: and receiving a mouse pointer display state setting instruction through the application thin client.
Step S104: and acquiring a target pointer display state carried by the mouse pointer display state setting instruction, wherein the target pointer display state comprises a hidden state or a display state.
The application thin client is an application client which is installed on Android equipment executing the method for setting the mouse display state in the application thin client and only has a display function or a few functions, receives and displays content issued by the cloud server, and does not process the content issued by the cloud server.
In this embodiment, a mouse pointer display state setting instruction issued by a server corresponding to an application thin client may be received by the application thin client. For example, when a user operates the application thin client to enter a full-screen playing PPT or a full-screen playing video, a mouse pointer of the user needs to be hidden, a mouse pointer display state setting instruction may be sent to the Android device executing the method for setting the mouse display state in the application thin client through a predefined communication protocol, where the instruction may include a target pointer display state, and the target pointer display state includes a hidden state or a display state. For example, in the mouse pointer display state setting instruction, a setting to a display state may be indicated by 1, indicating that the mouse pointer is desired to appear on the display screen, and a setting to a hidden state may be indicated by 0, indicating that the mouse pointer is desired to be hidden on the display screen.
In another embodiment, a mouse pointer display state setting instruction may also be input by the user. For example, a virtual function key is set on a display window of the thin application client, the pressed and popped states of the virtual function key can respectively represent a display state and a hidden state, when a user clicks the virtual function key, a mouse pointer display state setting instruction is input, and the pressed or popped state of the virtual function key is a target pointer display state carried in the mouse pointer display state setting instruction.
Step S106: and generating an intent message with the identifier for changing the display state of the pointer as an action parameter, and packaging the display state of the target pointer as an extension item parameter into the intent message.
In an Android system, an Intent mechanism is provided to assist interaction and communication between applications or components, wherein the Intent is responsible for describing actions and action related data and additional data of one operation in the applications, and the Android is responsible for finding a corresponding component according to the description of the Intent, transmitting the Intent to a called component and completing calling of the component. Intent can be used not only between applications, but also for interactions between activities/services within applications. Accordingly, Intent may be understood as an intermediary in the communication between different components that specifically provides the information about the components' calls to each other.
Intent has several attributes: action (Action), Data (Data), Category (Category), Type (Type), component (component), and extension (Extra).
In this embodiment, by setting an Intent action parameter and adding an extension parameter, and then broadcasting the extension parameter to the Android system, the Android system can hide or display the mouse according to an Intent message. Specifically, a predefined CURSOR _ VISIBLE _ CHANGED identifier in the Android system can be used as an action parameter of the Intent message, and Boolean-type data is used for representing a display state or a hidden state, so that the Intent message for informing the Android system of the display state of the bottom-layer operating mouse pointer can be generated.
For example, a developer may predefine a function as shown in Table 1:
TABLE 1
The generated message of the Intent type is an Intent object, the action parameter of the Intent object is an identifier formed by a CURSOR _ VISIBLE _ CHANGED character string, the shape parameter visbile target pointer of the incoming Boolean (boolean) type shows a state, and in the function, the Boolean variable visbile is added to the extension parameter of the Intent object.
In this embodiment, after receiving a mouse pointer display state setting instruction, the function may be called: and changeCursorVis, and transferring the display state of the target pointer carried by the mouse pointer display state setting instruction as a form parameter to a function and executing the function to generate the corresponding intent message.
Step S108: broadcasting the intent message to an Android system, searching a corresponding first interface function by the Android system according to an action parameter of the intent message, and calling the first interface function to set a display state of a mouse pointer by taking the display state of the target pointer as a parameter.
As shown in table 1, when the changeCursorVis function is called, referring to fig. 4, the generated intent message may be broadcast to the Android system through the context object, the Android system searches for the first interface function corresponding to the curser _ VISIBLE _ CHANGED identifier, and calls the boolean value of the extension parameter VISIBLE as a profile parameter, so as to set the display state of the mouse pointer. When the visual is true, displaying a mouse pointer; when the visible is false, the mouse pointer is hidden.
For example, in an application scenario, when a cloud server corresponding to an application thin client issues a video needing full-screen playing, a mouse pointer display state setting instruction is issued at the same time, a target pointer display state is set to be hidden, after an Android device receives the mouse pointer display state setting instruction, an event message with a CURSOR _ VISIBLE _ CHANGED identifier as an action parameter can be generated, a VISIBLE attribute is added to an extension parameter and then broadcasted to an Android system, after the Android system receives the event message, the pointer can be set to be hidden according to a first interface function corresponding to the CURSOR _ VISIBLE _ CHANGED identifier, and at the moment, when the video is played in the full-screen mode in the application thin client, the mouse pointer is hidden. And after the video is played, the cloud server corresponding to the application thin client can issue a mouse pointer display state setting instruction again, a target pointer display state is set in the mouse pointer display state setting instruction to be displayed, after the Android device receives the mouse pointer display state setting instruction, an event message with a CURSOR _ VISIBLE _ CHANGED identifier as an action parameter can be generated, a VISIBLE attribute is added into an extension parameter to be a true attribute, the event message is broadcasted to the Android system, after the Android system receives the event message, the pointer can be set to be displayed according to a first interface function corresponding to the CURSOR _ VISIBLE _ CHANGED identifier, at the moment, the mouse pointer is restored and displayed in the application thin client, and a user can perform next operation by operating the mouse. This allows the mouse pointer to perfectly function as an indication for the user operation, thereby improving the convenience of the operation.
In another embodiment, in order to solve the technical problem of insufficient operation convenience caused by the fact that the thin application client in the Android system in the conventional technology can only use the default setting of the mouse pointer, a method for redrawing a mouse pattern in the thin application client is further provided, and specifically, as shown in fig. 5, the method includes:
step S202: and acquiring the position information of the mouse pointer.
Step S204: and receiving material image data sent by a server corresponding to the application thin client.
The application thin client is an application client which is installed on Android equipment executing the method for setting the mouse display state in the application thin client and only has a display function or a few functions, receives and displays content issued by the cloud server, and does not process the content issued by the cloud server.
In this embodiment, the material image data sent by the server corresponding to the thin client application can be received by the thin client application. For example, when a user operates an application thin client to enter a scene having animation or a certain image style, it is necessary to modify an icon of a mouse pointer of the user to an icon that coincides with the scene. For example, in a cloud application of preschool education, a child can operate a thin client of the preschool education application to enter a Chinese character learning and animal recognition teaching course in a zoo scene, and the icon of a mouse pointer needs to be modified into an arrow of a card ventilation lattice. In the application scenario, the Android device executing the method for redrawing the mouse pattern in the application thin client may send the material image data of the card ventilation grid (for example, the cartoon image packaged by using a bitmap object) to the Android device executing the method for redrawing the mouse pattern in the application thin client through a predefined communication protocol, and then the Android device executing the method for redrawing the mouse pattern in the application thin client may redraw the mouse pointer based on the material image.
In another embodiment, the material image for redrawing the mouse pointer may also be set by a user operating the thin client application, and specifically, the obtaining of the mouse pointer position information is:
and receiving the input mouse pointer redrawing instruction through the thin client, and acquiring the mouse pointer position information carried by the mouse pointer redrawing instruction.
Receiving material image data sent by a server corresponding to the application thin client:
and acquiring a material link corresponding to the mouse pointer redrawing instruction, generating an access request according to the material link, sending the access request to a server corresponding to the application thin client, and receiving material image data corresponding to the material link returned by the server.
That is to say, a server corresponding to the application thin client can issue a page, wherein the page comprises a plurality of material links url, each material link corresponds to a corresponding material image, a user can trigger a mouse pointer redrawing instruction by clicking the material link, meanwhile, a request is initiated to the server corresponding to the application thin client according to the material link, and after the server corresponding to the application thin client receives the access request, the server can issue material image data corresponding to the material link to the application thin client.
Step S206: and generating an intent message with the identifier of the changed pointer display image as an action parameter, and packaging the mouse pointer position information and the material image data into the intent message as an extension parameter.
In an Android system, an Intent mechanism is provided to assist interaction and communication between applications or components, wherein the Intent is responsible for describing actions and action related data and additional data of one operation in the applications, and the Android is responsible for finding a corresponding component according to the description of the Intent, transmitting the Intent to a called component and completing calling of the component. Intent can be used not only between applications, but also for interactions between activities/services within applications. Accordingly, Intent may be understood as an intermediary in the communication between different components that specifically provides the information about the components' calls to each other.
Intent has several attributes: action (Action), Data (Data), Category (Category), Type (Type), component (component), and extension (Extra).
In this embodiment, by setting an Intent action parameter and adding an extension parameter, and then broadcasting the extension parameter to the Android system, the Android system can redraw the mouse according to the Intent message. Specifically, a predefined MOUSE _ ICON _ CHANGED identifier in the Android system can be used as an action parameter of the Intent message, and the MOUSE pointer position information of the current MOUSE and the material image data sent by the server are used as extension parameters to generate the Intent message for notifying the Android system of redrawing the MOUSE pointer at the bottom layer.
For example, a developer may predefine a function as shown in Table 2:
TABLE 2
The generated message of the Intent type is an Intent object, the action parameter of the Intent object is an identifier formed by a MOUSE _ ICON _ CHANGED character string, the introduced shape parameter bit of the Bitmap (Bitmap) type is material image data, x and y of the digital type respectively represent the current x axis position and y axis position of the MOUSE, and in the function, the data of the Bitmap type and the position (x, y) of the MOUSE are added into the expansion item parameter of the Intent object.
In this embodiment, after receiving a mouse pointer display state setting instruction, the function may be called: and changeCursorVis, and transmitting the bitmap-type material image data sent by the server and the acquired current mouse position as parameters to a function and executing the function to generate the corresponding intent message.
Step S208: broadcasting the intent message to an Android system, searching a corresponding second interface function by the Android system according to an action parameter of the intent message, and calling the second interface function to set a display state of a mouse pointer by using the position information of the mouse pointer and the material image data as parameters.
As shown in table 2, when the changeCursorVis function is called, referring to fig. 6, the generated intent message may be broadcast to the Android system through the context object, the Android system searches for the first interface function corresponding to the motion _ ICON _ CHANGED identifier, and calls the material image of the extended item parameter Bitmap type and the x and y values of the MOUSE position as parameters after being transmitted, that is, the redrawing pattern and the redrawing position of the MOUSE pointer may be set. For example, when the mouse position is (0,0), if the material image data is a cartoon image, the cartoon image is drawn at the (0,0) position of the display interface to replace the mouse pointer.
For example, in an application scenario, after a cloud server corresponding to an application thin client issues cartoon-type material image data, Android equipment receives the material image data and acquires the position of a current MOUSE pointer, an intent message with a MOUSE _ ICON _ CHANGED identifier as an action parameter is generated, a bitmap is added into an extension parameter as the material image data, the MOUSE position is an attribute of (x, y), the attribute is broadcast to an Android system, after the Android system receives the intent message, the bitmap image can be drawn at the (x, y) position of a display interface according to a first interface function corresponding to the MOUSE _ ICON _ CHANGED identifier, and at the moment, the MOUSE pointer in the application thin client is redrawn as the bitmap image. Therefore, the mouse pointer can be displayed in different display backgrounds with a more striking effect, so that the function of indicating the operation of the user is well played, and the convenience of the operation is improved.
