Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail.
In one embodiment of the invention, described virtual key is one and is accompanied by the application software that os starting starts, and it shows virtual key UI on described Touch Screen.Fig. 1 is for resurrecting an embodiment process flow diagram of the method for described virtual key UI in Touch Screen optional position.To having the equipment of operating system and Touch Screen, one embodiment of the present of invention comprise step:
S1, obtain all touch events on Touch Screen described in current time, and enter step S2.
If the described touch event of S2, for two positions, place that are apart less than on described screen apart from d1 are touched simultaneously, enters step S3, otherwise returns to step S1.Preferred described d1 is 10 centimetres of physical distances.
S3, Time delay start the timer t of virtual key UI, and enter step S4.When described timer is triggered since 0 timing.
S4, obtain all touch events on Touch Screen described in current time, and enter step S5.
If the described touch event of S5 meets: the positional number being touched is 2, and the two place's spacing that are touched are less than d1, and when two places that are touched and triggering timing device t separately the relative displacement of present position be no more than d2, enter step S6, otherwise, return to step S1.Preferred described d1 is 10 centimetres of physical distances, and described d2 is 2 centimetres of physical distances.
If S6 timer t has reached default duration, enter step S7, otherwise, return to step S4.Preferably, described default duration is 0.8 second.
S7, calculating resurrect the position of described virtual key UI, and resurrect virtual key UI in described position.Preferably, for resurrecting the mid point of two positions, place that are touched when the described position of described virtual key UI is triggering timing device t.
Described in described step S1, described in Real-time Obtaining, the implementation of all touch events on Touch Screen includes but are not limited to following two kinds:
The first, all described touch event that operating system is received sends to client layer, makes client layer application software can catch in real time all touch events on described Touch Screen.Concrete, for Android system, revise Android system source code InputDisplatcher.cpp file, add a unix domain socket function, for the touch event of all overall situations is all passed to client layer, rather than only only the relevant touch event of application software is passed to corresponding described application software.First in the constructor of InputDispatcher, create unix domain socket(TouchSocketThread), and monitor this socket, wait software is linked this socket and is obtained touch event.When having touch event, android can capture these events, and in notifyMotion function, process these events, so revise this function, the motion events(NotifyMotionArgs that Android system is received) by unix domain socket, send out, client layer just can be caught all touch events like this.
For Android system, the method that another kind obtains all touch events on described Touch Screen is, by the input event under read/dev/input.But read this document, need root authority, and to need further to analyze be touch event or other events (as, button) again, and will constantly detect and whether have new equipment to add.And these events have been carried out in android source code, utilize the existing code of android, by simple method, realize, can avoid unnecessary computing cost.
Figure 2 shows that the process flow diagram that utilizes above-mentioned first method to obtain touch event.
S11, sets up unix domain socket, and monitors this socket, waits for that application layer is connected to this socket, when having touch event to occur, enters step S12;
S12, Android system is caught touch event, and unified processing in notifyMotion, and enters step S13;
S13, the socket setting up by step S11 passes to upper strata touch event, and enters step S14;
S14, application software is obtained overall touch event by socket, when having touch event to occur, returns to step S12.
In one embodiment, described virtual key UI comprises not busy state and deployed condition, and in the situation that not using described virtual key UI, or described in initialization during virtual key UI, described virtual key UI is in not busy state.Described virtual key UI under not busy state is presented at the edge of screen, and lower of this state can show an icon, and shows with translucent figure, as Fig. 3.System button and quick application icon are outputed in described virtual key UI exhibitions under deployed condition, as Fig. 4.User can realize corresponding function by the function button of clicking on described virtual key UI, such as returning to homepage, return last layer, open menu, starting predefined application software etc.Described virtual key UI can change between not busy state and deployed condition, and be no matter not busy state or deployed condition under described virtual key UI can be dragged.These attributes of described virtual key UI should be set before described step S1.Therefore as shown in Figure 5, before step S1, also can comprise step:
S01, while setting not busy state described in the attribute of virtual key UI, comprise the edge in screen with translucent state, initialized described virtual key UI is not busy state;
S02, while setting deployed condition described in the attribute of virtual key UI, comprise and show the function button that comprises system button and quick application icon;
S03, sets the conversion of described not busy state and described deployed condition;
S04, sets the mobile effect while dragging described virtual key UI.
Figure 6 shows that described step S03 sets the particular flow sheet of described not busy state and the conversion of described deployed condition:
S031, when described virtual key UI is during in not busy state, if receive the touch event of clicking described virtual key UI, described virtual key shows in the former deployed condition of sentencing; While dragging described virtual key UI to the touch event of screen optional position if receive, dragging while finishing, described virtual key automatically with deployed condition in described position display;
S032, when described virtual key UI is during in deployed condition, if confiscate in a period of time, click or drag the touch event of described virtual key UI, or while receiving outside described virtual key UI the non-touch event that resurrects virtual key UI, described virtual key UI enters not busy state.
Concrete, from not busy state, entering deployed condition has two kinds of methods.First method is, clicks described virtual key UI under not busy state, and now described virtual key UI can forward described deployed condition to from described not busy state.The position when position showing is described not busy state.Another kind method is, on Touch Screen, place two fingers of any non-virtual key UI touch described screen simultaneously and keep a period of time, now described virtual key UI also can forward described deployed condition to from described not busy state, and the position showing is the mid point of two place's touch locations.
From deployed condition to not busy state, also there are two kinds of methods.First method is, within a period of time, in 5 seconds, within the scope of described virtual key UI, there is no touch event, described virtual key UI enters described not busy state from described deployed condition, and described virtual key UI is position while returning to screen Left or right according to described deployed condition, decides, if take back in the position of described deployed condition, just get back to the screen left side, if the position of described deployed condition takes over, just get back to screen the right.The method realizing is: set a timer, after 5 seconds, described virtual key UI is proceeded to described not busy state from described deployed condition, if having touch event within the scope of described virtual key UI, the timer of resetting, calculates in 5 seconds, whether there is touch event again.Second method is, clicks the position outside described virtual key UI scope, and described virtual key UI enters described not busy state from described deployed condition.Implementation method is: first obtain overall touch event, then judge that touch scope is whether outside this UI and for resurrecting the touch event of virtual key UI, if outside described virtual key UI and not for resurrecting the touch event of virtual key UI, described virtual key UI enters described not busy state.Determine according to the position touching the position of returning, if the position touching takes over, described virtual key UI just returns to screen the right, if taken back, returns to the left side of screen.
Further, be effect described in performing step S04, while starting described virtual key UI initialization, described virtual key UI is not the form operation with Activity, but moves with the form of Service.While dragging described virtual key UI, according to the change in displacement of clicking, constantly upgrade the coordinate of described virtual key UI, the effect moving to reach described virtual key UI.
Although be appreciated that above embodiment completes under Android system, the scope that the present invention covers is not limited in Android system, on the contrary, the present invention is intended to cover all systems with inventive concept.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
