The concrete can be adjusted according to the actual use requirement.
In this embodiment, the preparation phase may correspond to a preparation process, the switching phase may correspond to a switching process, the preparation phase may be sent to one or more standard components, the switching phase may be sent to one or more standard components, during sending, the preparation phase may be sent according to a certain preset sequence, or may not be sent in sequence, or the sending sequence may be adjusted according to actual usage needs, and each standard component may also correspond to one or more theme switching status bits, and the sub-step 20351 may include the following sub-steps:
substep 203511, defining a theme switching status bit corresponding to the standard component by configuration.
Substep 203512, sending said preparation phase to the corresponding standard component according to said preparation flow and sending said switching phase to the corresponding standard component according to said switching flow by said theme switching status bit.
In this embodiment, the theme-switching status bit defined by configuration may be used to locate a current status, a current location, or a current component, etc. of the standard component, so that a user may conveniently check and query a specific location or a specific location where a switching request is executed, and each component or component of the vehicle-mounted terminal may be ensured to obtain a response to the theme scene switching request.
In the following, the status bit is illustrated by an example:
for example, the following flag bits may be set by configuration.
int UI _ MODE _ depth _ MASK =192; // theme switching MASK flag bit;
int UI _ MODE _ method _ UNDEFINED =0; // theme switch default flag bit;
int UI _ MODE _ mean _ CLEAR =63; // subject switch clear flag bit;
int UI _ MODE _ method _ PREPARE =64; v/topic switch preparation flag bit;
int UI _ MODE _ method _ CHANGED =128; // subject switch change flag bit;
a preparation flag bit may be set to 64 for theme switching, and if the preparation flag bit for theme switching of the standard component is 64, the theme switching status bit of the standard component is a theme switching preparation status, and the preparation stage may be sent to the standard component, and the standard component may perform an operation of the switching preparation stage in response to a switching request of the preparation stage. If the flag bit of the plurality of standard cells is 64, the preparation phase may be sent to the plurality of standard cells, and the plurality of standard cells may perform a handover preparation operation upon receiving a handover request of the preparation phase.
In the above example, the status bit is represented by setting a flag bit. In practice, a person skilled in the art may set the status bit according to actual needs, which is not limited in the embodiment of the present invention.
If the standard component does not respond to the theme switching request, the theme switching status bit of the standard component cannot be defined, and if the standard component has a corresponding theme switching request, the triggered theme switching request can be determined by defining the theme switching status bit for the standard component. For example, a theme switching status bit of a standard component may be located, and if there is a response, the preparation stage may be sent to the corresponding standard component according to the preparation flow through the theme switching status bit. Then, defining the theme switching state bit of the standard component, if the standard component can be defined, the standard component corresponds to the preparation stage of the theme switching request, and performing the theme switching operation, and if the standard component cannot be defined, the standard component does not respond to the preparation stage of the theme switching request.
