Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under performing creative labour prerequisite, belong to the scope of protection of the invention.
Fig. 1 is the schematic flow sheet of method that the mobile terminal of the embodiment of the present invention is dynamically redirected volume key.As shown in Figure 1, mobile terminal is dynamically redirected the method for volume key and comprises:
Step S10: at preset function interface, receives and responds the first operation signal, being moved near volume key by icon corresponding for preset function.
Particularly, user is at the interface (interface of taking pictures as camera) of icon including preset function, press...with one's finger this icon, and dragged near volume key, then finger is decontroled, now, this volume key is redirected the function (as camera function) into correspondence, and this volume key side also shows this icon simultaneously.
Wherein, preset function can be camera function or sound-recording function etc., and this is not restricted.Volume key comprises volume and adds key or volume down key.Icon corresponding for preset function can be moved to volume and add key or volume down key.In other embodiments of the present invention, icon that also can be corresponding by different preset functions moves to different volume keys.As camera function icon moving corresponding for camera function added key to volume at camera interface, and recording interface by sound-recording function icon moving corresponding for sound-recording function to volume down key.On the contrary, also can be at camera interface by camera function icon moving corresponding for camera function to volume down key, and recording interface sound-recording function icon moving corresponding for sound-recording function is added key to volume.
Step S11: the function corresponding to icon is redirected to volume key, when making volume key receive push button signalling, controls to perform preset function.
In step s 11, the function register that application layer applications interface function is redirected volume key is received; An order broadcast is sent to application layer.
Alternatively, after the function corresponding to icon is redirected to volume key, at arbitrary function interface, when volume key receives push button signalling, judge whether volume key have registered redirection function; If so, then send this order broadcast to application layer, after making application layer receive broadcast, perform preset function.So make user can perform preset function fast, improve Consumer's Experience.
In embodiments of the present invention, when needing the redirection function nullifying volume key, the method that mobile terminal is dynamically redirected volume key also comprises: receive and respond the second operation signal, making icon away near volume key; Nullify the redirection function of volume key.
Alternatively, take preset function as camera function be example, mobile terminal is dynamically redirected the method schematic diagram of volume key as shown in Figure 2, at camera application function interface, in advance shutter icon being set to can be trailing, and see the figure a in Fig. 2, wherein A is that volume adds key, B is volume down key, and C is camera function icon.At camera application function interface, by shutter icon moving to volume down key side, as figure b, when decontroling icon, application program to the redirection function of the operating system registration volume down of mobile terminal, and specifies the icon that will show and the newer command that will perform simultaneously.Complete volume key be redirected after, demonstrate this icon registered on volume down key side, be redirected to point out the function of user's volume down key.See figure c, complete volume key be redirected after, at any function interface, namely current application program interface may not be camera function interface, and volume down keyed jointing receives volume key event, perform camera function.As schemed shown in d, if the redirection function of volume down key will be nullified, only the shutter icon on volume down key side need be removed, making shutter icon away from volume down key.
In embodiments of the present invention, as shown in Figure 3, mobile terminal application operating system layer 10 and application layer 11 realize the redirection function of volume key.At Application Program Interface, operating system layer 10 receives the function register of the redirected volume key of application layer 11, and can send an order broadcast to application layer 11.
More specifically, operating system layer 10 receives the registration of application layer 11, is redirected with the function realizing volume key.Need to define the interface function that application layer can be called for this reason, because volume key can add key or volume down key for volume, can define two interface functions, one adds the interface function that key function is redirected for volume, and one be the redirected interface function of volume down key function:
Only can certainly define an interface function, utilize the parameter in interface function to distinguish volume to add key or volume down key, effect is the same.
When application layer 11 application interface function carry out volume key function be redirected registration time, first operating system be presented at the icon of preset function on screen, to point out user, then records the order of be redirected preset function.For Android system, the order of the preset function be redirected is placed in BindingIntent (a kind of packaging container of order), save when pressing volume key event in BindingIntent, wish order broadcast (Intent) that operating system layer 10 sends, in operating system layer 10, preserved the redirection function of volume by Two Variables mVolumeKeyDownFunction and mVolumeKeyUpFunction.Operating system layer 10 can by judging whether mVolumeKeyDownFunction or mVolumeKeyUpFunction is that sky judges whether to be provided with redirection function.
When user presses the volume key on mobile terminal side, namely when volume key receives the first operation signal, operating system layer 10 first can receive key-press event, and then pass to application layer 11 and process, application layer 11 dynamically registers the New function of volume key to operating system layer 10, if after application layer have registered New function, operating system layer 10 performs new function after receiving key-press event, so just achieves being redirected of volume key function.Be implemented as, application layer 11 just registers an order to operating system layer 10, just sends the order of this registration after operating system layer 10 receives key-press event simply, or is received by application layer 11 and realize this order.Like this will be very flexible, improve Consumer's Experience.
When user has dragged icon after near volume key away from, operating system layer 10 can carry out the cancellation of redirection function, and its interface function realized is as follows:
Above-mentioned interface function is called by operating system layer 10, realizes icon to drag away near volume key, to nullify the redirection function of volume key.After the redirection function of volume key is canceled, cancels the icon display on volume key side, then variable mVolumeKeyDownFunction and mVolumeKeyUpFunction is set to sky.
Mobile terminal is after having key-press event to occur, need to judge whether it is volume key event, and judge whether further to have registered redirection function, namely whether mVolumeKeyDownFunction or mVolumeKeyUpFunction is empty, if then send the broadcast of redirection function.
Particularly see Fig. 4, the method that mobile terminal is dynamically redirected volume key comprises:
Step S100: start.
Step S101: key-press event occurs.
Step S102: determine whether that volume adds event.If so, then step S103 is performed; If not, then step S105 is performed.
Step S103: judge whether the redirection function that registration volume adds.If so, then step S104 is performed; If not, then step S105 is performed.
Step S104: the order broadcast sending registration.Then terminate.
In step S104, preset function is redirected to volume and adds key, making volume add keyed jointing when receiving push button signalling, performing preset function, as taken pictures.
Step S105: determine whether volume down event.If so, then step S106 is performed; If not, then step S108 is performed.
Step S106: the redirection function whether registering volume down.If so, then step S107 is performed; If not, then step S108 is performed.
Step S107: the order broadcast sending registration.Then terminate.
In step S104, preset function is redirected to volume down key, when making volume down keyed jointing receive push button signalling, performs preset function, as taken pictures.
Step S108: perform normal subsequent treatment.
In step S108, represent that volume adds key and volume down key is not all redirected preset function, now perform corresponding function according to push button signalling, namely if volume adds key signals, then perform volume and add function.If volume down key signals, then perform volume down function.If other key signals, then the corresponding function performing other keys.
Step S109: terminate.
In the invention process, after completing the redirection function of volume key, no matter whether application program exits, as long as press volume key all will perform relevant function.So application layer can start a background service, receive registration and broadcast to the order of operating system layer.Broadcast to the order of operating system layer to receive oneself registration as camera application program can start a background service, after receiving this order broadcast, just connect camera apparatus, and after making a system initial configuration, call takepicture function interface to take pictures.
If camera application program starts, just can not go again to connect camera apparatus, if therefore camera application program is in foreground initiation, then cancel the monitoring to order broadcast in the background service started, only have and just allow background service snoop command broadcast when camera application program exits foreground.When camera application program in foreground initiation, then monitor set order by camera application program and broadcast, after receiving relevant order broadcast, carry out photographing operation.
