Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following detailed description is provided in connection with examples. It should be understood that this embodiment is merely one aspect of the application of the present invention and is not intended to limit the present invention.
As shown in fig. 1, a method for implementing an STK menu includes the following steps:
and S01, numbering all the menus in the STK according to a predefined rule, and ensuring that the upper menu is associated with the lower menu.
The invention hopes to convert the menu hierarchy into menu numbers, and ensures that the upper menu and the lower menu are associated, so that the currently executed menu can be calculated reversely by using the defined calculation rule when the menu is distributed. The main aim of the menu numbering method is to realize convenient and direct conversion of menu levels and menu numbers. The present invention is not limited to a specific menu numbering method, and a preferred menu numbering method is shown in the present embodiment. Such as:
s101, presetting the number of bytes for carrying out menu number (case id) according to the number of STK menu levels, wherein each menu level uses half bytes.
If the menu level is small, 1 byte is used, and the menu level is large, and 4 bytes can be considered to be set, but according to the current menu architecture, 2 bytes are generally used.
S102, determining which level of menu is allocated with a nibble, setting a value for the allocated nibble at the same time, and then allocating the rest bytes for the subsequent level of menu, wherein the setting is performed from left to right by starting with the set nibble, the value of the nibble occupied by the lower level of menu is item identification (item id) which is increased from top to bottom according to the menu structure, and inheriting the set nibble value of the upper level of menu.
TABLE 1
Table 1 defines the case where two byte variables are used to store menu numbers, representing a level 4 menu with 3 nibbles, where the submenus of the first level menu L0 are L1-1, L1-2, L1-3, respectively; the submenus of the second level menu L1-1 are L2-11, L2-12 and L2-13 respectively; the submenus of the third level menu L2-11 are L3-111, L3-112, L3-113, respectively. The numbers in each level of menu brackets are the corresponding case ids, for example, the case id of L3-111 is 0x111.
For the present embodiment, the first level menu L0 is only one menu, and can be used as an entry, and its case id is set to, for example, 0 or 1 as long as it is not repeated with the subsequent menu. However, since setting 1 takes half a byte, which is somewhat wasteful, it is recommended to set the first menu to 0, which has a menu number of 0x000. For this case, it is actually the actual allocation of nibbles from the second level menu for menu numbering. If there are 3 first level menus in other embodiments, half bytes are allocated from the first level menu numbered 0x100, 0x200, and 0x300, respectively.
In the present embodiment, the nibbles are formally allocated for the menu numbers from the second level menu, so the number of L1-1 can be set to 0x100, and the number of the next level menu is set according to two conditions at the same time:
(1) Item identification (item id) starting to increment from top to bottom by menu structure;
(2) Inherits the nibble value set by the upper menu.
For example, in the lower menu, the item identifier itemid of the first submenu is set to 1, then item id of the second submenu is generally set to 2, and so on. The number of the upper menu is 0x100, and the first submenu number is 1 set for the half byte on the right of the half byte value of the upper menu, resulting in 0x110. According to this method, the numbers of the lower menus shown in table 1 can be obtained. The menu structure is clearly understood by the numbering, by turning the level of the menu into the menu number.
In other embodiments, before numbering each menu in the STK, the menu characters are converted into byte codes and stored in the menu buffer, and the buffer names are defined according to the menu level, so that the readability is higher, the user can know which menu is processed at a glance, and the accuracy of the numbering is ensured. In addition, the number of each menu can be defined by using a macro, and the name of the macro corresponds to the buffer of the trigger menu one by one. Such as: after clicking L0, displaying an L1 level menu, if a case id macro corresponding to processing after clicking L0 is defined as ITEM0 (= (0 x 000)), then a buffer storing the level menu can be correspondingly defined as ITME0_buf, thus when writing codes, the names of the corresponding menu buffers are not needed to be found one by one, and the codes can be directly written according to rules defined in advance. For example, the case id macro handled by L1-3 is defined as ITEM3, the buffer names storing L2-31 and L2-32 menu byte codes are defined as ITEM3_buf, the case id macro handled by Level2-31 is defined as ITEM31, the buffer names storing Level2-311 and Level2-312 menu byte codes are defined as ITEM31_buf, and so on.
S02, setting a common Select item active command function for all menus.
All menus are displayed by utilizing a shared selection active command, so that the code space can be reduced, and simultaneously the selection active command is called uniformly, the returned result is located at one place, the received user operation can be conveniently processed, and the unified menu distribution operation is performed.
S03, presetting a menu distribution step corresponding to user operation, and reversely calculating the menu number to be executed according to the numbering rule of S01.
Corresponding to the specific embodiment in S01, the method for reversely calculating the menu number to be executed according to the number rule in S01 includes:
when the received user operation is a menu rollback application, setting the upper menu number of the backup as a menu to be executed; or,
when the received user operation is to select to enter a lower menu, setting the currently executed menu as an upper menu, and recording the item identification (item id) of the lower menu to be entered; when a nibble with the value of 0 is detected from the leftmost side of the upper menu number to the right, the nibble number N on the right side of the nibble is recorded, the item identification of the lower menu is moved to the left by N nibbles, and the number of the upper menu is added, so that the menu number to be executed is obtained, wherein N is an integer greater than or equal to 0.
A menu number calculation method when the received user operation is selected to enter the lower menu will now be described in detail as an example.
Step 1: the currently executed menu is set as the upper menu, and item identification (item id) of the lower menu to be entered is recorded.
As shown in Table 1, for example, when the currently executed menu is L1-1 (0 x 100) and the next menu to be entered is L2-12, L1-1 (0 x 100) is set as the previous menu, and the item identification 2 of the next menu to be entered is recorded.
Step 2: when a nibble with the value of 0 is detected from the leftmost side of the upper menu number to the right, the nibble number 1 on the right side of the nibble is recorded, the item identification 2 of the lower menu is moved to the left by 1 nibble to obtain 0x20, and then the number 0x100 of the upper menu is added to obtain the menu number 0x120 to be executed.
It can be understood that if the upper menu is L2-11 (0 x 110), the item identifier of the lower menu to be entered is 3, the item identifier 3 of the lower menu is directly added with the number of the upper menu without moving leftwards, so as to obtain the menu number 0x113 to be executed, and then it is determined that L3-113 needs to be entered.
It will be appreciated that in actual operation, a user click may also be received to exit, or an exception may be performed, at which point the application is exited.
The steps S02 and S03 of the invention will now be described with reference to the code:
the menu entry function uses while to carry out circulation judgment, and the inside uses switch case sentences to carry out leveling distribution processing on each level of menu, after distribution, each case only carries out variable initialization of a selector active command, then exits the switch case, and uniformly calls the selector, and the return value is located at one place, so that menu number conversion can be uniformly carried out, and menu distribution is realized.
The meaning of the content of the Selectite active command, item identifier (item identifier) and the like can be added to the GSM11.14 and the SIM card application technical specification.
Some description will be made with reference to fig. 2 and 3. Fig. 2 is a main flow chart of the STK menu operation. After entering from the menu application portal, the menu number is set to the portal menu number, e.g., ITEM0 (number of L0), i.e., let sim card display the L0 menu first. Then judging the execution condition of the menu, including (1) the execution is finished; (2) rollback operations; (3) entering the next level menu. For the first case, the application is directly ended, and for the latter two cases, the menu number to be executed is calculated, and the distribution of the menus is unified. The method of calculating the menu number to be executed can be seen in fig. 3.
The invention sets corresponding numbers for the menus in advance according to the menu hierarchy condition, sets a shared selectetime active command function for all the menus, is used for displaying the menus, and then presets the menu distribution steps which need to be executed after receiving the user operation. In actual operation, all menus are displayed by using a shared selection active command, so that the code space can be reduced, and simultaneously the selection active command is called uniformly, the returned result is located at one place, the received user operation is convenient to process, and unified menu distribution operation is performed. After receiving the user operation menu command, the menu hierarchy can be converted into a menu number, and then the currently executed menu is calculated through rules so as to carry out menu distribution. The menus are connected through the designed numbering rules and are not mutually independent, and the menu level and the rollback mechanism are clearer.
