Description

TECHNICAL FIELD The present invention relates to the field of mobile terminal technologies, and in particular, to an apparatus and method for implementing horizontal and vertical screen switching of a mobile terminal. BACKGROUND With the increasing application of mobile terminals, the display requirements of mobile terminals are getting higher and higher, the screens of mobile terminals are getting larger and larger, and some wide screens are also appearing on the screen, which provide display for mobile terminals. With good conditions, the display requirements have also been improved, and the switching of horizontal and vertical screens has gradually emerged. The horizontal and vertical screen switching technology refers to the automatic rotation of the screen image when the mobile terminal is switched between the horizontal direction and the vertical direction to meet the visual needs of the user. Since the width and height conditions of the horizontal screen display and the vertical screen display change, the interface of the terminal application also needs to be changed accordingly. However, this change is not a simple change between horizontal and vertical. The position and size of the interface elements will also change, and even some elements in the interface will disappear, otherwise it will bring a bad visual experience to the user. The current way to achieve horizontal and vertical exhibition is mainly in the following two ways:

1) The developer provides two sets of MMI programs, and when the horizontal and vertical screens are switched, the corresponding MMI program is run.

2) The developer uses the automatic layout control when developing the MMI program. When the horizontal and vertical screens are switched, the automatic layout control automatically arranges the interface elements to adapt to the change of the screen width and height. For the first method, it is obvious that this method is more complicated, and the developer's workload is relatively large. The second way is simpler, but because of the automatic layout, the position and size of the elements of the interface are automatically calculated by the layout control. Most of the interface after switching is not beautiful, affecting the user experience, and if you encounter MMI users. With a lot of layout controls, MMI runs more slowly. In addition, not all GUI systems have support for automatic layout controls. Therefore, it is necessary to find a horizontal and vertical screen switching method which is simpler and more likely to generate a controllable interface, and can bring a better sensory body-risk to the user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an apparatus and method for realizing a mobile terminal horizontal and vertical display switching according to an embodiment of the present invention will be described in detail with reference to FIGS. As shown in FIG. 1 , an apparatus for implementing horizontal and vertical screen switching of a mobile terminal according to an embodiment of the present invention includes: an interface description file unit, an interface parsing engine, and a GUI control unit. The interface description file unit is configured to describe each interface of the mobile terminal, and save the description of each interface in the horizontal screen and the vertical screen state in the interface description file, where the interface description file includes the interface. Interface elements and their properties. The interface element refers to each display component in the display interface. For example, the interface elements may be GUI controls. Its attributes refer to the composition information of the interface elements, such as position, height, width, displayed text/picture, and so on. The GUI control unit is a graphical user interface, configured to parse the corresponding interface called by the I engine according to the interface, and draw corresponding interface elements. An interface parsing engine is configured to parse the interface description file in the interface description file unit according to the current screen state, and the interface element obtained by the parsing invokes a corresponding interface provided by the GUI control unit; and is further used to maintain between the interface element and its attribute. The corresponding relationship is used for drawing by the GUI control unit, so that the interface element can display the latest data information in time. A Man Machine Interface (MMI), which is an interface for a user to perform a horizontal and vertical screen switching operation of a mobile terminal, and is composed of a plurality of interface elements. In addition, the apparatus for implementing the horizontal and vertical screen switching of the mobile terminal in the embodiment of the present invention may further include an interface design tool for simultaneously setting configurable attributes of the interface elements in the horizontal screen and the vertical screen state. Developers can use this tool to design and develop application interfaces. Developers can develop an interface for applications in landscape and portrait orientation, and this tool can save the interface as an interface description file in a specified format. The interface design tool here can simultaneously set the position and size of the interface elements in the horizontal and vertical screen states. The interface design tool refers to the tools similar to Microsoft's VC and VB. The tool contains various interface elements. The developer only needs to place the interface elements with the mouse, and finally get the desired interface. Of course, the interface design tool adapts to different GUIs to support the controls of the GUI. Interface design tools can be developed on their own or they can be designed using the existing open source Eclipse framework. In addition, the above interface description file is an XML file. As shown in FIG. 2, the method for implementing the horizontal and vertical screen switching of the mobile terminal according to the embodiment of the present invention includes the following steps: Step 201: The programmer uses the interface design tool to design the application interface, and uses the tool to design the interface relative to the handwritten code. Say it is fast. Because of the switch between horizontal and vertical screens, developers here need to design the horizontal and vertical screens. The interface design tools need to provide two horizontal and vertical screen design functions. Of course, the programmer can skip this step and directly write the interface description file. This requirement for programmers is relatively higher. Step 202: The interface design tool saves the developer's interface design as an interface description file in a specified format. Of course, the description file herein includes interface information when the horizontal screen and the vertical screen are included. Description The file format of the piece can be:

</wnd> From the above code, you can see that each control on the interface will contain two pieces of position information and size information, in the case of the front screen and the horizontal screen. As in the previous example code, the window element with ID 1 has a coordinate position of (0, 10) under the vertical motion, a width and a height of 180 and 30 respectively, and a coordinate (0, 20) in the horizontal screen state. And high for 240 and 20. The information in the two states is separated by ";". If there is no such element in a certain state, no information is required, such as an interface element with an ID of 3 or 4. Step 203: Save the interface description file in a specified location of the file system of the mobile terminal, so that the interface parsing engine can apply the interface description files according to the situation. Step 204: The interface parsing engine will find the interface description files for node parsing and call the interface of the GUI to display the interface. When the terminal uses the user to switch the screen state, the system will receive this information, and start the interface parsing engine to rebuild the interface. The interface parsing engine will detect the current screen state, and then construct the MMI interface according to the corresponding attributes of the interface elements. And show it. As shown in FIG. 3, it is a flowchart for implementing vertical screen to horizontal screen switching of a mobile terminal according to an embodiment of the present invention. Of course, the process of switching from landscape to portrait is similar. Step 301: The current state is the vertical screen state; Step 302: When the user rotates the mobile phone, the information of switching to the horizontal screen state is generated; Step 303: The interface analysis engine finds that the current state of the screen changes and changes the state of the current state; Step 304: The screen state is changed, and the display interface is also changed. The interface parsing engine re-analyzes the interface element part of the interface description file, and obtains the position and size information of each element in the horizontal screen state; Steps 305 and 306: Parsing engine Obtain the original data of the interface element and assign it to the corresponding interface element, which is the cornerstone for the following display; Step 307: Interface analysis I engine will analyze the new interface element information, call the GUI drawing interface to interface element Draw it out and display it in the interface. The interface in the horizontal screen state is displayed in front of the end user. In summary, the apparatus and method for implementing the horizontal and vertical screen switching of the mobile terminal according to the present invention can fully utilize the trend characteristics of the interface structure by using the description file, as long as the original description file and the interface parsing engine are simply modified. Support for horizontal and vertical screen switching can reduce the development of existing methods, and the interface after switching is more beautiful and efficient. The above is a detailed description of the present invention to enable those skilled in the art to understand the invention, but it is contemplated that other variations and modifications may be made without departing from the scope of the invention as claimed. These changes and 4 tampering are all within the scope of the present invention.
