Description
Technical field
The present invention relates to a kind of method changing screen of hand-held device display direction, especially a kind ofly realize device screen display by shake equipment in a program and turn to the method for gravity direction.
Background technology
Current mobile phone other mobile computing devices such as (or) panel computers, often all with gravity sensing equipment, makes these equipment can perceive the anglec of rotation of the vertical direction of screen, and can allow screen display content synchronous automatic rotation with it.The setting of this automatic rotation screen content is all generally the Default Value of these equipment.Meanwhile, equipment manufacturers also notice, sometimes user can wish that the direction of screen is fixed, and the direction that gravity sensor does not detect rotates, and its reason is that the major part of certain customers checks that custom is fixed as some directions, to reach certain convenience.Such as, mobile phone screen is fixed as perpendicular screen direction by certain user, so neither affects him and plays the activities such as phone at ordinary times, when can also ensure that he reads web page contents in the situation of lying on one's side, web page contents can not become horizontal screen because of the reason of gravity sensing, causes reading.But for the user in this fixed mask direction, they also exist inconvenience: such as check webpage or document content in perpendicular screen situation, sometimes font is too small, is not easy to check, horizontal screen display is now needed to show.And when now mobile phone laterally holds by this user, screen content can't automatic rotation (because being set to lock perpendicular the screen by himself).If now this user wants the object reaching horizontal screen reading, the setting of aforementioned lock-screen manually must be removed.And after horizontal screen reading is complete, again obtain the convenience that the perpendicular screen of locking brings if wish, need to remember screen to be manually set to again lock perpendicular screen.
Now, the usual way of application software is on program interface, provide Rotation screen button or menu, but this needs to take interface shape, and likely because itself there is more function button or menu, cause this function cannot by user's Timeliness coverage.
Or when equipment rotates, position ejector button obvious on screen, prompting user presses rear roller blind, and this not only blocks the sight line of user, and likely not all situation user needs roller blind, always ejects such button and user can be allowed to feel to bother.
Summary of the invention
The problem to be solved in the present invention is, when user's fixed mask direction, by a kind of simple, can operate intuitively and be transformed into gravity screen orientation temporarily.Therefore, the object of the invention is to thisly often be in lock-screen direction state to allow, but frequently have that to change the user that screen orientation needs more convenient to use.
The present invention is realized by shake equipment the method that device screen display turns to gravity direction in a program realized this object by a kind of, and it comprises following steps:
Step one: get the relevant service of current device sensor by call operation system when entering application-specific;
Step 2: whether judgment device has acceleration transducer and gravity sensor;
Step 3: obtain the data that acceleration transducer exports, the time of the acceleration of record acceleration transducer report and accekeration, calculate the first adjacent acceleration and the mistiming of the second acceleration, and mobile phone screen X, Y, the absolute value of acceleration change between first acceleration and the second acceleration on Z tri-axle, following formulae discovery is utilized to go out the mean value of rate of acceleration change according to the absolute value of described mistiming and acceleration change again: speed=(deltaX+deltaY+deltaZ) × C/diff, wherein speed is the mean value of rate of acceleration change, deltaX, deltaY, deltaZ is respectively mobile phone screen X, Y, the absolute value of acceleration change on Z axis, diff is the first adjacent acceleration and the mistiming of the second acceleration, C is amplification coefficient, by described mean value speed compared with the threshold value preset, judge when mean value is greater than mean value threshold value to create primary acceleration great change, and record current acceleration great change generation time, in acceleration great change counter, 1 is added to the number of times of acceleration great change, if the mistiming that the time of wherein current acceleration great change and last time acceleration great change produce be greater than one preset mistiming threshold value time, degree of will speed up great change counter clear, when the number of times of acceleration great change reaches default frequency threshold value, judge that producing user shakes screen action, when judging that producing user shakes screen action, calculate and currently shake screen action and last mistiming of shaking screen action, and will the mistiming of screen action be shaken compared with the mistiming threshold value preset, judge that when the described mistiming is greater than mistiming threshold value user shakes screen action effectively, and degree of will speed up great change counter clear,
Step 4: obtain the data that gravity sensor exports, the gravity direction of record gravity sensor report;
Step 5: the gravity direction of heavier force snesor report and current screen display direction, rotate current screen display direction according to gravity direction in the case of inconsistencies;
Step 6: exit or reset routine time, by Operation system setting or program itself acquiescence configuration setting screen direction.
Like this, when equipment is locked into any direction, user shakes one and to shake the hand machine, if the direction of current screen content display and the direction that should turn to by gravity sensing inconsistent, then the direction that current screen content shows is converted to consistent with the screen orientation that gravity sensing indicates.The problem of the interim Rotation screen of the hope that the user solving lock-screen faces, and there is not the defect of prior art.And; this scheme has very strong intuitive: according to the observation to use scenes; user is after slewing to some directions; find the words that screen does not rotate; the equipment of the subconscious shake of frequent meeting oneself (mobile phone, panel computer, etc.); this is because user thinks that in subconsciousness equipment is container, screen content is the object that can slide with gravity in container.The present invention just in time when the in-mind anticipation of identical user, can meet the demand of user.
Embodiment
In this particular embodiment, we are described to use the smart mobile phone of android system, and the realization of the present invention on the smart mobile phone adopting other operating system similarly.
First, the present invention realizes the judgement to the action that user " shakes " by the acceleration transducer that android system provides, and this judgement can Activate Phone the change in screen display direction.Particularly, the Activity.getSystemService (Context.SENSOR_SERVICE) by calling android system gets the relevant service SensorManager of current device sensor; Then from SensorManager, the acceleration transducer on equipment is got by getDefaultSensor (Sensor.TYPE_ACCELEROMETER), if return null, then current device does not support acceleration transducer, cannot realize shaking function, otherwise, pass through SensorManager.registerListener, the monitoring of registration acceleration transducer, realizes the acquisition to acceleration transducer signals thus.
The upper acceleration transducer of Android comprises the acceleration on equipment three directions:
X-axis: device screen level to the right
Y-axis: device screen straight up
Z axis: outside device screen Vertical dimension
So, equipment constantly reports current acceleration (per second be more than or equal to 5 times) by onSensorChanged (SensorEvent event), contain when the real time acceleration on first three direction in the values of wherein event, values [0] represents the acceleration in X-axis, values [1] represents the acceleration in Y-axis, and values [2] represents the acceleration on Z axis.
The present invention is by the change to the acceleration on these three directions, and judge " shaking " action, concrete scheme is as follows:
Wherein, predefined variable and meaning thereof comprise:
Event: system reports the subsidiary acceleration information object of acceleration
MLastTime: upper subsystem reports the time of acceleration
MLastX: the X-axis acceleration that last time reports
MLastY: the Y-axis acceleration that last time reports
MLastZ: the Z axis acceleration that last time reports
MLastHugeChangeTime: the time (implication of acceleration great change is explained in 2) that acceleration great change last time produces
MHugeChangeCount: the acceleration great change number of times produced continuously, is initially 0
MLastShakeTime: the record last time of shaking a shake and doing to produce, be initially 0
Like this, when first time reports acceleration, record current time mLastTime, and acceleration mLastX=event.values [0], mLastY=event.values [1], mLastZ=event.values [2].
When again reporting acceleration, obtain current time now, mistiming diff is calculated by now-mLastTime, calculate the absolute value of the acceleration change on three directions, what namely current X-axis acceleration event.values [0] deducted mLastX thoroughly deserves deltaX, correspondingly calculate deltaY, deltaZ, three cumulative after be multiplied by amplification coefficient C(at this for 10000 divided by mistiming diff, namely 10000 times are expanded), obtain the mean value speed that describes rate of acceleration change on three directions, by judging whether this speed exceedes default mean value threshold values (such as 350, this is experiment value, this value is used to judge to shake error quite little).If do not arrive this mean value threshold values, only record current time and present acceleration.If arrival threshold values, then judge to create primary acceleration great change, and record current acceleration great change generation time mLastHugeChangeTime, and make the number of times mHugeChangeCount of the acceleration great change in acceleration great change counter add 1.Wherein, when system reports acceleration, obtain current time, if the time mLastHugeChangeTime that current time and last time acceleration great change produce differ by more than one preset mistiming threshold value (such as 500ms) time, decision people just moves equipment, does not shake a shake and does, now mHugeChangeCount is set to 0, otherwise continue to increase great change number of times, namely mHugeChangeCount adds 1.
When mHugeChangeCount number reaches default frequency threshold value, such as 3 times time, judge the action creating " shaking ", and the time of active user the being shaken screen action user that deducts last registration shakes the time of screen action, obtain the mistiming between the two, (such as 1000ms when only once mLastShakeTime is greater than default mistiming threshold value in current time distance, wherein mLastShakeTime is defaulted as 0, so when first time, generation was shaken, must satisfy condition), be just judged as and effectively shake screen action.The object of record mLastShakeTime does not stop in user's short time to shake mobile phone to prevent, and causes and once produce the too much situation of shaking effect.When shaking screen action and being judged as effective, first arranging mHugeChangeCount is 0, restarts counting, and records the current time to mLastShakeTime.
Then, the data of gravity sensor output are obtained by the operating system of equipment, the gravity direction of record gravity sensor report.The gravity direction of heavier force snesor report and current screen display direction, rotate current screen display direction according to gravity direction in the case of inconsistencies, makes both consistent.
When arranging screen orientation, obtain current screen orientation, another kind of screen orientation is being arranged to according to gravity direction, this arranges not write-in program configuration, the setting of system is not changed yet, therefore, when program exits and restarts, setting screen direction can be come by the configuration of the setting of system or program itself.
Like this, when equipment is locked into any direction, user shakes one and to shake the hand machine, if the direction of current screen content display and the direction that should turn to by gravity sensing inconsistent, then the direction that current screen content shows is converted to consistent with the screen orientation that gravity sensing indicates.The problem of the interim Rotation screen of the hope that the user solving lock-screen faces, and there is not the defect of prior art.And; this scheme has very strong intuitive: according to the observation to use scenes; user is after slewing to some directions; find the words that screen does not rotate; the equipment of the subconscious shake of frequent meeting oneself (mobile phone, panel computer, etc.); this is because user thinks that in subconsciousness equipment is container, screen content is the object that can slide with gravity in container.The present invention just in time when the in-mind anticipation of identical user, can meet the demand of user.
Certainly, the present invention is except above-mentioned embodiment, and other equivalent technical solutions also should within its protection domain.
