Description
Technical Field
The invention relates to the field of intelligent televisions, in particular to a method and a system for realizing full keyboard function keys of an intelligent television.
Background
In order to solve the problem of non-uniformity of key values of input equipment of various manufacturers, the Android system sets a key distribution mechanism as follows:
for each device driver that needs to provide a corresponding kl map file, the kl map file path is as follows, system/usr/keyayout/. For example: the kl mapping file corresponding to the drive used by the remote controller hardware is system/usr/keyylayout/vector _0019_ Product _0001. kl; the kl mapping file corresponding to the driver used by the standard keyboard hardware is system/usr/keyayout/general. kl, and which device selects which kl mapping file is determined according to the VID (i.e. vendor ID) and PID (i.e. device ID) of the hardware.
When the system is started, the corresponding relation between the drive layer key value and the Android key value of the corresponding equipment is established according to the kl mapping file; for example: the remote controller is provided with an A key, and the key value of a driving layer of the A key is 23; the qwerty keyboard also has an "a" key with a drive level key value of 30. However, in the kl mapping file of the remote controller, the 23 drive layer key value is corresponding to the 40 key value of the Android system layer, and in the kl mapping file of the standard keyboard, the 30 drive layer key value is corresponding to the 40 key value of the Android system layer. The result is that although the definition key values of the remote controller and the driving layer of the standard keyboard for the key of "a" are different, the key values reported to the application program after Android system side mapping are all the same 40, so as to realize the function of shielding hardware difference.
At present, the utilization rate of the smart television on the market for the function keys of the standard keyboard (full keyboard) is not high. The existing standard keyboard function key is realized by directly modifying key mapping, and the essence is that a kl mapping file is directly modified. For example: for a remote controller, a key value reported by a key driving layer is set to be 10, the key value of 10 of the key driving layer is mapped with a key value of 20 of an Android system side corresponding to a kl mapping file, and the Android calls out a setting application in response to the key value of 20; for the standard keyboard, the key value reported by the key driving layer of "F1" is 11, the corresponding kl mapping file maps the key value of 11 of the driving layer with 131 of the Android system side before being modified, the Android regards the key of 131 as F1 and assigns the key to the application program, and the existing modification mode is to correspond the key of 11 of the driving layer in the kl mapping file of the standard keyboard to 20, that is, the aforementioned "Android responds to the key of 20 is to call out the setting application", so as to implement that the keyboard function key completes the quick start function.
From the implementation described above, the F1 key in the qwerty keyboard would not be able to serve its key corresponding to 131 of the Android system to the application. For example: when F1 needs to be input inside the text edit box, the corresponding function cannot be realized.
Therefore, the conventional modification mode cannot realize normal reporting of the keys, but only can realize the modified quick start function, and is not beneficial to the expansion and modification of the function keys.
Accordingly, the prior art is yet to be improved and developed.

Detailed Description
The invention provides a method and a system for realizing full keyboard function keys of an intelligent television, and the invention is further described in detail below in order to make the purpose, the technical scheme and the effect of the invention clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for implementing full keyboard function keys of an intelligent television according to a preferred embodiment of the present invention, as shown in the figure, the method includes the following steps:
s101, adding a configuration file in a framework layer of the smart television system in advance;
s102, reading the configuration file when the system is started, and establishing a key value mapping table of an application program and a keyboard function key;
s103, when an instruction of a user for operating the keyboard is received, whether the operated key is a function key is judged, and if yes, the corresponding application program is searched in the key value mapping table according to the key value of the function key and is started.
As shown in fig. 2, in the present invention, a configuration file (e.g., a keyboardfunctionality key. txt file) is added to a framework layer of an Android system, and the configuration file is read when the smart television is started, and a key value mapping table is established; when the intelligent television system is started and functional keys are reported, the Android system framework part searches a key value mapping table established before; and starting the corresponding application program to realize the function of shortcut key pressing.
The modification mode of the invention is realized on the upper layer of the Android system, namely after the kl mapping file is mapped. For example: the key value of 11 on the driving layer corresponds to 131 on the Android system side before the key value of 11 on the driving layer is modified by an F1 key on the standard keyboard, and the Android considers that the key value of 131 is F1 and distributes the F1 to an application program; the invention judges the key value as the key value of the function key at the system side, for example, if the key value is 131, the invention reads the key value mapping table, and then finds the application program corresponding to the key value; the application is started.
The key value mapping table is an array in nature; the process of establishing the array is that the configuration file is read when the system is started, and then the array (two-dimensional) is established, and the content is the corresponding relation between the key value of the function key and the application program. In the invention, the quick starting function of the function key is completed when the system responds, namely the system can search and start the corresponding application program under the condition that the key is not reported to other application programs. The original keys (such as F1, 131) report other application programs unchanged; for example: when the text edit box needs to input the character 'F1', the character is not affected; and when the application program is quickly started, the function of quickly starting the application program can be realized. In the existing modification mode, the kl mapping file is modified, and the key value sent by the Android to the application program is changed into the corresponding key value, so that the kl mapping file is influenced.
Further, the content of the configuration file is a key value of the keyboard function key, and a name of an application package and a name of an Activity component (Activity name) which need to be started and correspond to the key value.
The purpose of adding the configuration file is to read the configuration file when the intelligent television system is started so as to establish a corresponding key value mapping table. Txt file, the file content is "F1 (key value 131), for example, if the file name is keyboardfunctionality, the name of the application package needs to be started; the application class name needs to be started,
further, as shown in fig. 3, the step S102 specifically includes:
s201, when the system is started, judging whether a configuration file exists in a framework layer, if so, entering a step S202, and if not, entering a step S204;
s202, reading the configuration file, judging whether the format of the configuration file is correct, if so, entering a step S203, and if not, entering a step S204;
s203, establishing a key value mapping table of the application program and the keyboard function key according to the read content;
the key value mapping table of the keyboard function key is a linked list, the corresponding relation between the function key value and the corresponding application package name and Activity name which need to be started is stored, so that the corresponding application package name and Activity name can be found after the key value of the function key is obtained, and the corresponding application and Activity thereof can be started.
And S204, ending.
Further, as shown in fig. 4, the step S103 specifically includes:
s301, when an instruction of a user for operating the keyboard is received, judging whether the key is a function key according to a pre-established function key array, if so, entering a step S302, and if not, turning to a step S304;
that is, an array of function keys (such as F1-F12, and corresponding key values) is preset in the frame layer, when a user operates the keyboard, it is first determined whether the key is a function key, if the key is a function key, for example, the key value of the key is 131, the key value mapping table is read, and then an application program corresponding to the key value is found; the application is started.
And if the function key is not the function key, processing according to the Android native flow.
S302, searching whether a corresponding application program exists in a key value of the function key in the key value mapping table, if so, entering a step S303, and if not, entering a step S304;
s303, starting a corresponding application program;
and S304, ending.
Further, after step S103, the method further includes:
and sending a broadcast when the application program is started, judging whether the broadcast is a broadcast corresponding to the application program after the application program receives the broadcast, and hiding the application program when the broadcast is not received.
When two or more than two application programs which are not full screens are started, the problem of window overlapping exists, for example, when two keys are pressed successively, two application programs which are not full screens are started. For the situation, the invention sends the broadcast after starting the application, the content of the broadcast includes the Activity name of the current starting application program (for example, the Action field is "com.tcl.shortcutkey", the Type field is "application Activity name"), then when the started and starting application program receives the broadcast, it is determined whether the broadcast is the broadcast corresponding to itself, if not (if the application determines that the Type field is not the Activity name of itself), it will hide itself automatically, otherwise it starts normally, thus realizing the effect of mutual exclusion. For example, when application a (widget) is activated by a first key and application b (widget) is activated by a second key, application a receives a broadcast (and is not a broadcast corresponding to itself), and is automatically hidden from window coverage. Hiding in the present invention refers to exiting the Activity of the application to avoid overlapping windows.
Based on the above method, the present invention further provides a preferred embodiment of a system for implementing full keyboard function keys of an intelligent television, as shown in fig. 5, which includes:
