Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.
According to the embodiment of the invention, provide a kind of keyboard locking method of portable terminal.
As shown in Figure 1, this method comprises:
Step S102 is provided with locking key dish trace routine (trace routine that can comprise automatic locking keyboard and manual lock keyboard) in the keyboard detection program, detecting under the situation that satisfies predetermined condition, and locking key dish trace routine starts the locking key dish and uses; Step S104, using the logic of locking key dish application independently, module encapsulates; Step S106, the handover mechanism that utilizes the locking key dish to use is starting the application of hanging up current activation when the locking key dish is used, when withdrawing from the application of locking key dish, the application that recovery is suspended (this step is to realize automatically on most of mobile phone operating systems, otherwise needs the user manually to realize).
Wherein, locking key dish trace routine starts the processing that the locking key dish uses and further comprises: step S202, catch KeyEvent before KeyEvent being sent to the application of current activation in the keyboard detection program; Step S204 carries out preliminary treatment to the KeyEvent of catching, and judges whether to satisfy the predetermined condition that starts the application of locking key dish; Step S206 according to the judged result among the step S204, starts the locking key dish in a different manner and uses.
Below will describe the testing process of KeyEvent in the above-mentioned processing in detail further combined with Fig. 3.
The KeyEvent trace routine that startup locking key dish shown in Fig. 3 is used is that the locking key dish is used the correct key that starts.For convenience of explanation, suppose that the automatic locking keyboard is to be triggered without any button in the given time, trigger the back and start the application of locking key dish and directly enter lock-out state; The manual lock keyboard is to be triggered after length is by " # " key, point out the user to press and do the locking that software carries out keyboard this moment, if the user does not press this key at the appointed time, then close the locking key dish that just has been activated and use, and (following description is also based on this kind hypothesis) used in the current activation that recovers to be suspended.
It should be noted that the locking key dish is used must carry out after start is finished, because only after core application all normally starts, the locking key dish is just meaningful.
1, system's KeyEvent catches
In step S202, particularly, to obtain KeyEvent at system kernel and decipher with the application that becomes current activation after the discernible KeyEvent code, KeyEvent is caught in the application that KeyEvent is sent to current activation before.This is because the keyboard detection task of system normally is independent of application, has only to catch KeyEvent at this moment and just can carry out the most comprehensive judgement so that correctly lock judgement.
2, the startup flow process of locking key dish application
In order to carry out the keyboard lockout of success, be unable to do without the use of timer.
The automatic locking keypad function need set in advance automatic locking keyboard timer, so that starting the locking key dish after regularly finishing automatically uses, if in the timing of automatic locking keyboard timer, do not have button operation, then start the application of locking key dish and automatically lock keyboard, otherwise restart the reclocking of automatic locking keyboard timer.This is the logic of automatic locking keyboard.Certainly, the automatic locking keypad function can be closed in that module is set, and timing also can be set up module settings in addition.
The realization of manual lock keypad function also be unable to do without timer, because about fixed length is used for manually booting the locking key dish by " # " key, so in order to realize the manual lock keypad function, set in advance long by " # " key timer, when pressing " # " key, start long by " # " key timer, if be released by " # " key in the timing of " # " key timer long, then cancellation is long by " # " key timer cancellation timing, if be not released by " # " key in the timing of " # " key timer, then start the locking key dish and use long.
Notice that EVT_KEY, EVT_KEY_PRESS and EVT_KEY_RELEASE represent respectively that key-press event, button are pressed incident, button lifts incident among Fig. 3.
In addition, in order to give the flexible processing mode of using, the decision logic that can the application of a current activation locked (locking) is wherein arranged, locking key dish trace routine is before starting the application of locking key dish, need also to judge that can the application of current activation locked, here mainly be the inquiry current application whether allow to carry out keyboard lockout in case take corresponding operation (judged result for situation not under, detect next time, in judged result is under the situation that is, with the application locking of current activation).Notice that this application does not need to lock once more for the locking key dish, that is, in a single day system just is in the lock state and can not be locked once more.
Like this, in step S204, predetermined condition be following any: do not have button operation in the given time; The user has carried out the button operation of particular sequence.Correspondingly, in step S206,, directly start the locking key dish and be applied to the keyboard lockout state judging in the scheduled time do not have under the situation of button operation; Judging that the user has carried out under the situation of button operation of particular sequence, starts the locking key dish and is applied to the Subscriber Locked state of waiting for.
Based on content described above, further describe other subsequent treatment after the testing process of KeyEvent.
As shown in Figure 4, the processing among the step S104 further comprises: step S402 copies the screen display of the application of current activation, the screen background of using as the locking key dish; Step S404 realizes the interface that the locking key dish is used according to the state machine pattern, makes the corresponding different interface of different state machine patterns, and according to the migration at Event triggered interface; Step S406 simulates the logic that the locking key dish is used by the migration at interface.
Wherein, Fig. 5 shows the system mode transition graph that the locking key dish is used, and can find out realization logic (mechanism by a kind of state machine realizes) that the locking key dish uses clearly for the simplest realization applied logic by this figure, the interface state below the definition:
(a) released state: no interface, will close application this moment.
(b) wait locks: bottom strip left side soft key is for locking.
(c) manually lock successfully: bottom strip and background become ash, and prompting " successfully locking keyboard ", and bottom strip left side soft key is for locking.
(d) automatic lockout success: bottom strip and background become ash, and prompting " successfully locking keyboard ", the bottom strip that bottom strip is used for locking.
(e) lock-out state: bottom strip is the little image of a locking sign.
(f) release prompting: bottom strip and background become ash, and prompting " is carried by separating locking key by the # key earlier ".
(g) wait for release: background becomes ash, and prompting " please by separating locking key ", and bottom strip left side soft key is release.
(h) release success: bottom strip and background become ash, prompting " successful release keyboard ".
Need to prove that background above-mentioned is meant and enters the interface that the activation before the locking key dish is used is used that just activate application and be suspended front interface, it is to obtain by the copy current screen; Bottom strip is meant zone, mobile phone screen below, is mainly used to show the concrete function of current left and right sides soft key.
Can clearly find out the concrete event handling logic that the locking key dish is used according to Fig. 5: the locking key dish is used main hang-up and the recovery incident of handling key-press event and application.For key-press event, main " # " key and the left soft key (being responsible for locking or release) paid close attention to, other buttons then directly eject corresponding prompt, play the effect of final shield keyboard incident.For the hang-up incident, mainly be system mode to be set so that correct display interface when recovering; For the recovery incident, mainly be that the state of system is drawn the interface when hanging up.It should be noted that and do not show the processing of hanging up the recovery incident among the figure.
By the present invention, can solve present most mobile phone can only lock keyboard under standby interface limitation, make it possible to achieve the keyboard lockout under all application, thereby improved cellphone subscriber's experience.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
