Fig. 2 is the structured flowchart of system that the present invention realizes Android device virtual key and hides and show.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described.
The present invention mainly optimizes the array mode of View class, is packaged into the function interface hidden completely, partly hide and show completely three kinds of patterns of virtual key.When interfaces windows loads, readjustment onCreate () method, call the function interface of encapsulation in the method flexibly, the flexible control of this interfaces windows to virtual key can be realized, realize the sweetly disposition of window to virtual key of oneself, specific implementation process detailed in Example 1 and embodiment 2.
Embodiment one
Please refer to Fig. 1, a kind of method conveniently realizing Android device virtual key and hide and show disclosed by the invention, it comprises the following steps:
Step S1, general (or conventional) attribute of View class is optimized combination, be packaged into completely hiding, half function interface that is hiding and display three kinds of patterns completely of virtual key, the function interface of often kind of pattern is with a corresponding function parameter;
Step S2, establishment one provide the virtual key display of the function interface of three kinds of patterns to serve, and run in the process of system;
Step S3, rewrite requestFeature (intflag) method of window interface class according to described function interface;
Step S4, when window interface refreshes, call requestFeature (intflag) method of described rewriting, and transmit different function parameters.
Wherein, in step S1, so-called general-purpose attribute refers to that the function that View class realizes is classified, then the View class of same alike result is combined and be assembled into a function interface, the corresponding function operation of virtual key can be realized by this function interface of requestFeature (intflag) method call at window interface, general-purpose attribute comprises hides attribute completely, half hides attribute and complete display properties three attribute, the interface of optimal combination assembling is hide () according to this, partyHide () and fullDisplay (), what represent virtual key respectively hides function interface completely, half hides function interface and complete explicit function interface, and the assembling attribute of often kind of function interface is total (public) attribute.
Such as: the combination of hiding virtual key is completely as follows, it combines having the View hiding attribute completely:
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
View.SYSTEM_UI_FLAG_FULLSCREEN
View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
The interface of encapsulation is hide (), the completely hiding of virtual key can be realized by requestFeature (intflag) method call hide () method at window interface, half hide and show virtual key completely realize similar, just the combination of their corresponding View attribute is from completely hiding different.
The concrete grammar realized in step S2 is: create virtual key display service (VirtualKeyDisplayService), it mainly provides the function interface of above-mentioned three kinds of patterns, this virtual key display service is after system starts, served by ActivityManagerService and start and run in system process, like this, each application program just can call the interface of three virtual key patterns that this service provides at any time, reaches the object of dynamic setup window virtual key pattern.
In step S4, when window interface refreshes, requestFeature (intflag) method of rewriting is called by this pointer, and transmit different parameters, the different different disposal of parameter representative to virtual key, so far realizes the flexible control of modules interfaces windows to virtual key, without the need to independent process modules being carried out to virtual key, optimum code structure, reduces code redundancy, improves development efficiency.
Embodiment 2
On the basis of embodiment 1, the present invention also provides a kind of system conveniently realizing Android device virtual key and hide and show, and please refer to shown in Fig. 2, it comprises: function interface encapsulation unit 10, establishment service unit 20, rewriting unit 30 and call unit 40.Wherein: function interface encapsulation unit 10 is for being optimized combination by the general-purpose attribute of View class, be packaged into completely hiding, half function interface that is hiding and display three kinds of patterns completely of virtual key, the function interface of often kind of pattern is with a corresponding function parameter.Creating service unit 20 for creating the virtual key display service that provides the function interface of above-mentioned three kinds of patterns, running in the process of system.Rewriting unit 30 is for rewriteeing requestFeature (intflag) method of window interface class according to described function interface; Call unit 40, for when window interface refreshes, calls requestFeature (intflag) method of described rewriting, and transmits different function parameters.
In function interface encapsulation unit 10, so-called general-purpose attribute refers to that the function that View class realizes is classified, then the View class of same alike result is combined and be assembled into a function interface, the corresponding function operation of virtual key can be realized by this function interface of requestFeature (intflag) method call at window interface, general-purpose attribute comprises hides attribute completely, half hides attribute and complete display properties three attribute, the interface of optimal combination assembling is hide () according to this, partyHide () and fullDisplay (), what represent virtual key respectively hides function interface completely, half hides function interface and complete explicit function interface, and the assembling attribute of often kind of function interface is total (public) attribute.
Create in service unit 20, create a virtual key display service, it mainly provides the function interface of above-mentioned three kinds of patterns, this virtual key display service is after system starts, served by ActivityManagerService and start and run in system process, like this, each application program just can call the interface of three virtual key patterns that this service provides at any time, reaches the object of dynamic setup window virtual key pattern.
In call unit 40, when window interface refreshes, requestFeature (intflag) method of rewriting is called by this pointer, and transmit different parameters, the different different disposal of parameter representative to virtual key, so far realizes the flexible control of modules interfaces windows to virtual key, without the need to independent process modules being carried out to virtual key, optimum code structure, reduces code redundancy, improves development efficiency.
The above, it is only present pre-ferred embodiments, not technical scope of the present invention is imposed any restrictions, thus every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
