Embodiment
The invention provides a kind of method and system that realize the mobile terminal touch screen switching function, clearer, clear and definite for making purpose of the present invention, technical scheme and effect, below the present invention is described in more detail.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 1, Fig. 1 is the flow chart that the present invention realizes the method preferred embodiment of mobile terminal touch screen switching function, and as shown in the figure, it comprises:
S101, when mobile terminal being detected in talking state, start the large tracts of land touch function of mobile terminal touch screen and the driving of virtual P-sensor equipment;
S102, utilize the large tracts of land touch function to judge whether the state that approaches of mobile terminal touch screen changes, when being, by virtual P-sensor equipment records for meaning the current value that approaches the flag bit PS of state;
S103, utilize the driving of virtual P-sensor equipment to obtain the value of flag bit PS, the value of flag bit PS is passed to upper strata;
The function of switch touch-screen is realized on S104, upper strata according to the value of flag bit PS.
Should be noted that, in above-mentioned steps, for convenience of description by each step numbers, but do not represent the execution sequence of step, for example step S102 and step S103 are for carry out simultaneously.
Before step S101, need be pre-created virtual P-sensor equipment, requirement according to the MTK platform simultaneously creates corresponding driving for it, in the P-sensor device drives, the state that large tracts of land is touched is united and is reported upper strata with the state that closes screen and spread its tail, for upper strata, whole software architecture does not change.
MTK(MediaTek Inc.) platform is for the driver of each touch-screen of unified management, simultaneously in order to realize the compatibility of different touch-screens, carry out the compliant architectures of a set of touch-screen, in order to allow the touch-screen in the present invention drive and can, on operate in normally the MTK platform, also need to follow above-mentioned compliant architectures.The MTK platform has created a platform driver(platform that is called " mtk-tpd " and has driven), the touch-screen in the present invention drives and need be loaded into this platform driving above, and the function of use is tpd_add_driver (); After touch-screen drives and successfully is loaded into this platform and drives, touch-screen initialization and coordinate report and all pass through this touch-screen and drive realization.
Simultaneously, manage various transducers for convenience in the MTK platform, its establishment has a set of sensor management framework, it has created a platform driver(platform driving that is called " hwmsensor " simultaneously), carried out state reporting work here, the present invention is downloaded to virtual P-sensor hanging equipment in corresponding list by the hwmsen_attach function, so just can the data of virtual P-sensor equipment have been visited by the MTK framework, the MTK platform has interruption and two kinds of modes of poll when obtaining data, only need in driving, corresponding state registration be entered and get final product.
In step S101, when mobile terminal being detected in talking state, start the large tracts of land touch function of mobile terminal touch screen and the driving of virtual P-sensor equipment;
After touch-screen in the present invention drives and loads accordingly according to the MTK platform architecture, just can work, firmware(firmware in the inner programming of touch-screen drive IC (integrated circuit)) need to open corresponding function in, current state is obtained in the interruption that just can trigger by large tracts of land touch function (touch-screen need have the large tracts of land touch function) in communication process like this, as needs Guan Pingshi, just this state is kept to the value of variable ps_state(flag bit PS) in, wait for that P-sensor drives to obtain.
In whole communication process, need to guarantee that touch-screen is in running order, can not dormancy, can realize the large tracts of land touch function to guarantee touch-screen, switch touch screen function in the present invention simultaneously refers to the LCD of switch touch-screen, and when closing touch-screen LCD, touch-screen does not respond user's operation.
In step S102, utilize the large tracts of land touch function to judge whether the state that approaches of mobile terminal touch screen changes, when being, by virtual P-sensor equipment records, be used for meaning the current value that approaches the flag bit PS of state;
It specifically comprises: judge whether the touch-screen capacitance reaches threshold value, and whether the capped port number of touch-screen reaches predetermined number, when two conditions all meet, determine that the state that approaches of touch-screen is for there being object close, when two conditions all do not meet or only have a condition to meet, determine that the state that approaches of touch-screen is for close without object.When the state that approaches does not change, touch-screen will constantly continue to detect, and when changing, will record the current value that approaches the flag bit PS of state.
In step S103, utilize the driving of virtual P-sensor equipment to obtain the value of flag bit PS, the value of flag bit PS is passed to upper strata; Specifically, by the interface function of the poll that can provide by upper strata, the state of the ps_state preserved during touch-screen is driven reads, and reports to upper strata.
In step S104, the function of switch touch-screen is realized on upper strata according to the value of flag bit PS.
In whole flowchart process, touch-screen drives and the P-sensor driving all can continue to detect mobile terminal whether in communication process, if detect in communication process, touch-screen drives needs constantly to judge whether the current state that approaches changes, and P-sensor drives the value that needs continuous poll flag bit PS, and report upper strata.And detect not in communication process, touch-screen drives the pattern that large tracts of land touches that exits, and P-sensor drives and also can directly exit and close.
The present invention also provides the method that realizes the mobile terminal touch screen switching function another embodiment, and as shown in Figure 2, it comprises step:
S1, beginning;
S2, start the conversation; After starting conversation, system can be called two threads simultaneously: thread 1 and thread 2; Thread 1 comprises step S3 and S4, S5, and thread 2 comprises step S6, S7.
The large tracts of land touch function of S3, startup touch-screen;
Whether the state that approaches of S4, detection touch-screen changes;
S5, when detecting when approaching state and changing, record the value of current mark bit PS;
S6, startup P-sensor drive, the value of poll flag bit PS;
S7, report the value of flag bit PS to report upper strata;
Whether S8, judgement conversation finish; When finishing, execution step S9, otherwise return to step S3 and S6.
S9, end.
Based on said method, the present invention also provides the system that realizes mobile terminal touch screen switching function preferred embodiment, and as shown in Figure 3, it comprises:
Start module 100, for when mobile terminal being detected in talking state, start the large tracts of land touch function of mobile terminal touch screen and the driving of virtual P-sensor equipment;
Logging modle 200, judge for utilizing the large tracts of land touch function whether the state that approaches of mobile terminal touch screen changes, and when being, by virtual P-sensor equipment records, is used for meaning the current value that approaches the flag bit PS of state;
Further, described logging modle comprises:
Whether judging unit, reach threshold value for judging the touch-screen capacitance, and whether the capped port number of touch-screen reaches predetermined number; When two conditions all meet, determine that the state that approaches of touch-screen is for there being object close, when two conditions all do not meet or only have a condition to meet, determine that the state that approaches of touch-screen is for close without object.
Further, also comprise:
