For technical staff, the concrete meaning of above-mentioned term in the present invention can be understood with concrete condition.In addition, in description of the invention
In, unless otherwise indicated, the meaning of " plurality " is two or more.
Any process described otherwise above or method description are construed as in flow chart or herein, and expression includes
It is one or more for realizing specific logical function or process the step of executable instruction code module, segment or portion
Point, and the range of the preferred embodiment of the present invention includes other realization, wherein can not press shown or discussed suitable
Sequence, including according to related function by it is basic simultaneously in the way of or in the opposite order, to execute function, this should be of the invention
Embodiment person of ordinary skill in the field understood.
Shown in fig. 1 is the frame diagram of existing Android system, Fig. 2 shows be existing Android system Booting sequence figure,
It will thus be seen that Android system, which wants starting completely, first has to starting Native Services, it is compiled based on c/c++ language
Write, then to start the Java Services based on Java Virtual Machine, here it is Android system need to spend tens of seconds when
The reason of waiting to complete starting.It is so based on this, realizes the journey of the fast display method of this onboard system provided by the present application
Sequence is write using c/c++ language, when its operation follows Native Services to start together, entire without Android frame
Starting, this fast display method can start to work.
The software system framework of the fast display method of this onboard system is as shown in figure 3, whole system and Android
Framework is relatively independent, only relies only on fraction of Android Native Services, it is encapsulated
SurfaceFlinger, InputEVent and OpenGL.
Based on system above frame, the present invention provides a kind of fast display methods of onboard system, as shown in figure 4, packet
Include following steps：
When S1, Android system starting, OpenGL environment is initialized, window manager is created（Windowmanager）, creation is locally
Window：It calls draw to draw background picture and the functional areas of native window, the texture of control is drawn by OpenGLES, formed aobvious
Show the control icons in native window, to SurfaceFlinger application Surface, shows native window.Function in this example
Energy area is three, respectively parking assisting system area, reversing radar signaling zone and reversing image display area, parking assisting system area
There is corresponding control to be controlled with reversing image display area, when reversing radar generates signal, reversing radar signaling zone meeting
The corresponding warning picture of display.
S2, creation touch event handle thread, detect to touching signals, obtain touch event；
S3, each control are at least preset with a kind of touch manner, such as long-pressing, short-press, sliding etc., every kind of touch manner corresponding one
Kind or a variety of operational orders.Parse touch event：It is first obtained according to the position coordinates of touching signals from window manager corresponding
Then control judges the touch manner of touching signals, obtains operational order.
S4, the child window of native window is drawn according to parsing result and/or automobile is operated；
S5, step S2 ~ S4 is repeated.
As one example, as shown in figure 5, being a native window, including parking assisting system area 1, reversing radar signaling zone
2, reversing image display area 3, background picture 4, ESC Escape 5, switch key 6, image show that key 7 ~ 11, ESC Escape 5, are shown switch key 6
Picture key 7 ~ 11 is control, and image shows that key 7 ~ 11 is respectively intended to picture captured by the camera of different location on display vehicle body.
After Android system powers on, Draw and OpenGL rendering context picture 4, functional areas and control are first passed through, to
SurfaceFlinger application Surface shows native window.Create touch event handle thread, start to touching signals into
Row detection shows picture captured by corresponding camera in reversing image display area when short-press images key.When short-press switch key
When 6, imaging key 12 ~ 15 is drawn, all changes imaging key 7 ~ 11 into imaging key 12 ~ 15, short-press images key 12 ~ 15 later, is falling
Vehicle image display area 3 shows the reverse image of corresponding camera shooting, as shown in Figure 6.When starting automated parking system, draw
It parks close key 16, the lower section in parking assisting system area 1 shows close key 16 of parking, as shown in Figure 7.When short-press is parked close key
16, automated parking system is exited, the prompt information 17 to log off is drawn, as shown in figure 8, short in parking assisting system area 1
After temporary display reminding information 17, the display content in parking assisting system area 1 is destroyed, OpenGL is discharged.
In the description of this specification, reference term " one embodiment ", " some embodiments ", " example ", " specifically show
The description of example " or " some examples " etc. means specific features, structure, material or spy described in conjunction with this embodiment or example
Point is included at least one embodiment or example of the invention.In the present specification, not to the schematic representation of the term
Centainly refer to identical embodiment or example.Moreover, particular features, structures, materials, or characteristics described can be any
One or more embodiment or examples in can be combined in any suitable manner.
Taking the above-mentioned ideal embodiment according to the present invention as inspiration, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
