Method for television remote keypress response based on android operating system and television thereof
This application provides a method for method for television (TV) remote keypress response based on Android operating system (OS) and a TV thereof, and includes: creating a first process when the Android OS is being initialized; executing the first process to obtain a key value of a remote key event; and performing a remote keypress operation according to the key value. The method creates and executes the first process during the initialization of the Android OS, thereby realizing responding to remote keypress during TV start-up, greatly enhancing user experience.
1. A method for responding to a remote keypress, the method comprising:
during at least a portion of an operating system initialization process executing on a television, receiving, by the television, a remote key event;
during at least the portion of the operating system initialization process executing on the television, executing a first process in response to the remote key event, wherein the first process comprises determining a key value corresponding to the remote key event, wherein the determining a key value corresponding to the remote key event comprises:
obtaining a device list;
obtaining location information of at least one device node included in the device list, wherein each device node is stored under a first directory of the operating system for storing a key event corresponding to a key device;
determining location information of a device node from the device list;
accessing the device node according to the location information of the device node;
determining whether the remote key event is stored under the device node; and
in response to the remote key event being stored under the device node, obtaining the key value of the remote key event; and
performing, by the television, a remote keypress operation according to the key value.
2. The method according to claim 1 , wherein the remote key event is an event triggered by pressing a predefined key on a remote control.
3. The method according to claim 2 , further comprising:
acquiring an attribute of the key event corresponding to the key device, wherein the attribute of the key event corresponding to the key device comprises: a type of the key device.
4. The method according to claim 3 , wherein the attribute of the key event further comprises: a key state and a key value, wherein the key state comprises: a keyup state or a keydown state.
5. The method according to claim 3 , wherein the determining whether the remote key event is stored under the device node comprises:
determining whether the key event corresponding to the key device is the remote key event according to a type of the key device.
6. The method according to claim 1 , wherein the obtaining a device list comprises:
scanning the first directory of the operating system to obtain the location information of the device node under the first directory; and
generating the device list according to the location information of the device node under the first directory.
7. The method according to claim 1 , wherein the first directory is an input device directory under the device directory of the operating system.
8. The method according to claim 1 , wherein the first process comprises a BootAnimation process.
9. A television (TV), comprising:
a memory storing instructions;
a processor in communication with the memory, and wherein the processor is configured to execute the instructions stored in the memory to:
during at least a portion of an operating system initialization process executing on the television, receive a remote key event;
during at least the portion of the operating system initialization process executing on the television, execute a first process in response to the key event;
execute the first process to determine a key value corresponding to the remote key event by:
obtaining a device list;
obtaining location information of at least one device node included in the device list, wherein each device node is stored under a first directory of the operating system for storing a key event corresponding to a key device;
determining location information of a device node from the device list;
accessing the device node according to the location information of the device node;
determining whether the remote key event is stored under the device node; and
in response to the remote key event being stored under the device node, obtaining the key value of the remote key event; and
perform a remote keypress operation according to the key value.
10. The TV according to claim 9 , wherein the processor is further configured to:
acquire an attribute of the key event corresponding to the key device, wherein the attribute of the key event corresponding to the key device comprises: a type of the key device.
11. The TV according to claim 10 , wherein the attribute of the key event further comprises a key state and a key value, wherein the key state comprises: a keyup state or a keydown state.
12. The TV according to claim 10 , wherein the processor is configured to perform said determining whether the remote key event is stored under the device node by:
determining whether the key event corresponding to the key device is the remote key event according to a type of the key device.
13. The TV according to claim 9 , wherein the processor is configured to perform the obtaining a device list by:
scanning the first directory of the operating system to obtain the location information of the device node under the first directory; and
generating the device list according to the location information of the device node under the first directory.
14. The TV according to claim 9 , wherein the first directory is an input device directory under the device directory of the operating system.
15. The TV according to claim 9 , wherein the key value of the remote key event comprises a key value for indicating volume up.
16. The TV according to claim 9 , wherein the key value of the remote key event comprises a key value for indicating volume down.
