Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present invention provides an attribute information processing method, where the method includes:
step 101: and receiving a first attribute value, wherein the first attribute value is used for modifying first attribute information, and the first attribute information comprises an attribute name and a second attribute value.
Step 102: and modifying the second attribute value included in the first attribute information into the first attribute value to obtain second attribute information.
Step 103: and providing the second attribute information for the first application through a preset database item in a preset database which is monitored by the first application registration, wherein the first application is an application which needs to call the first attribute information.
In this embodiment, when the first attribute information is modified to the second attribute information, the second attribute information is provided to the first application through the preset database item in the preset database registered and monitored by the first application, so that the first application does not need to start an attribute monitoring thread to periodically poll to obtain the change of the attribute information, thereby reducing resource consumption and improving the real-time property of the application for obtaining the modified attribute information.
Referring to fig. 2, an embodiment of the present invention provides an attribute information processing method, including:
step 201: when an application in the terminal is started, registering the application to monitor a preset database item in a preset database.
In this embodiment, the terminal includes at least one attribute information, where the attribute information includes an attribute name and an attribute value, and each application in the terminal can call the attribute information.
Each attribute information in the terminal corresponds to a preset database item in a preset database (e.g., a system database), and when an application in the terminal is started, the application is registered to monitor the preset database item in the preset database. Or, each attribute information in the terminal corresponds to one preset database, but preset database items corresponding to each attribute information in the preset database may be different, and when the application in the terminal is started, the application is registered to monitor the preset database items corresponding to the attribute information that the application needs to call in the preset database.
In this embodiment, for any attribute information in the terminal, the attribute information is referred to as first attribute information. The first application is any application which needs to call the first attribute information in the terminal, and the first application comprises a database name and a preset database item of a preset database which needs to be registered and monitored. When the first application is started, the first application is registered to monitor the preset database item in the preset database.
The first attribute information comprises an attribute name and a second attribute value, and the terminal can be a mobile phone, a tablet computer and other terminals. For example, the first attribute information may be in the form of: [ sys.boot.animation ]: [ boot ], where sys.
The first application may be controlled by an attribute value included in the first attribute information. For example, it is assumed that the first application is an application for taking a picture, the attribute value included in the first attribute information may be used to control whether the first application uses a flash when taking a picture, and the first application is preset with the attribute name included in the first attribute information in advance.
The second attribute value included in the first attribute information is assumed to be used for controlling the first application to use the flash lamp when taking a picture, so that the first application calls the second attribute value included in the first attribute information according to the preset attribute name, and the flash lamp is started according to the second attribute value when taking a picture. If the flash is required to be turned off, only the second attribute value included in the first attribute information needs to be modified into the first attribute value, and the first attribute value is used for controlling the first application to turn off the flash, so that the first application calls the first attribute value included in the first attribute information according to the preset attribute name, and the flash is turned off according to the first attribute value during photographing.
The first application may call the second attribute value included in the first attribute information through the attribute call interface according to the attribute name. The first application may be an application written in Java, C, or C + +. The attribute calling interface comprises a Java side interface and a C/C + + side interface. When the first application is written by adopting Java language, the first application calls a second attribute value included in the first attribute information through a Java side interface according to the attribute name. When the first application is written by adopting C language or C + + language, the first application calls a second attribute value included in the first attribute information through a C/C + + side interface according to the attribute name.
The preset database is used for storing the corresponding relation between database items and database values. The preset database is a certain database in an operating system, and the operating system can be an Android system or an ios system. For example, assume that a preset database exists in the operating system as shown in table 1, the database identifier of the preset database is data1, and the preset database entry is property _ list. In the preset database, the initial value corresponding to the preset database entry property _ builder may be null or any value, and it is assumed that in this embodiment, the initial value corresponding to the preset database entry property _ builder is 0.
TABLE 1
| Database entry | Database values |
| property_listener | 0 |
| …… | …… |
The method comprises the steps that a first application is registered in an operating system of the terminal to monitor preset database items in a preset database. And when registering, correspondingly storing the application identifier of the first application, the database identifier of the preset database and the preset database item in the corresponding relation of the application identifier, the database identifier and the database item.
After the registration is completed, when the database value corresponding to the preset database entry in the preset database is changed, the operating system sends a notification event to the first application. And after receiving the notification event, the first application acquires a database value corresponding to a preset database item from the preset database according to the preset database item, wherein the acquired database value is the changed database value.
For example, assuming that the application identifier of the first application is APP1, when the first application requests the operating system to register and listen to a preset database item property _ holder in the preset database, the application identifier APP1 of the first application, the database identifier data1 of the preset database, and the preset database item property _ holder are correspondingly saved in the corresponding relationship of the application identifier, the database identifier, and the database item as shown in table 2.
TABLE 2
| Application identification | Database identification | Database entry |
| APP1 | data1 | property_listener |
| …… | …… | …… |
Step 202: a first attribute value is received, the first attribute value being used to modify the first attribute information.
The terminal has a second application which needs to modify the second attribute value included in the first attribute information, and the second application is also an application which needs to call the first attribute information. For example, assuming that the first attribute information is used to control whether the first application uses a flash while taking a picture, the second application may be a flash setting application, and the user may modify an attribute value included in the first attribute information through the second application to control whether the first application uses a flash while taking a picture.
The first attribute information corresponds to an attribute service program, and the attribute service program is a system program in an operating system. And when the second application needs to modify the second attribute value included in the first attribute information into the first attribute value, the second application sends the first attribute value to the attribute service program corresponding to the first attribute information through the attribute setting interface (setProperty). Accordingly, the first attribute value may be received by the attribute service program corresponding to the first attribute information.
Step 203: and modifying the second attribute value included in the first attribute information into the first attribute value to obtain second attribute information.
And after receiving the first attribute value through the attribute service program corresponding to the first attribute information, modifying a second attribute value included in the first attribute information corresponding to the attribute service program into the first attribute value to obtain second attribute information.
For example, the first attribute information is [ sys. And when the second application needs to modify the second attribute value boot included in the first attribute information into the first attribute value boot, the second application calls the setProperty interface and sends the first attribute value boot to the attribute service program corresponding to the first attribute information through the setProperty interface.
Receiving a first attribute value bootnew for modifying the first attribute information through an attribute service program corresponding to the first attribute information; then, modifying a second attribute value boot included in first attribute information corresponding to the attribute service program to a first attribute value boot by using the attribute service program corresponding to the first attribute information, wherein the obtained second attribute information is [ sys. [ bootnew ].
Step 204: and providing the second attribute information to the first application through a preset database item in a preset database monitored by the registration of the first application.
Specifically, a database value corresponding to a preset database item in a preset database is updated to be a first database value, the first database value includes modified second attribute information, that is, the second attribute information includes the attribute name and the first attribute value, so that the operating system controls the first application to read the first database value corresponding to the preset database item from the preset database, and thus the first application obtains the attribute name and the first attribute value included in the second attribute information from the first database value.
The updating of the database value corresponding to the preset database entry in the preset database to the first database value may include:
2041: a first database value is generated that includes the name of the attribute and the value of the first attribute.
Wherein the attribute name and the first attribute value are separated by a preset connector in the first database value.
The property _ change method may be invoked to splice the property name and the first property value included in the second property information into a character string, connect the property name and the first property value in the character string with a preset connector, and use the character string as the first database value.
For example, the second attribute information is [ sys. And (4) the preset connector is 'marked', a character string comprising the attribute name sys.
2042: and generating a database modification command carrying a preset database item and a first database value.
Specifically, a database modification command is called from an operating system of the terminal, a preset database item corresponding to the first attribute information is determined, the preset database item and the first database value are used as command parameters of the database modification command, and the database modification command carrying the preset database item and the first database value is generated.
The operating system of the terminal comprises a database modification command of 'setting put system # # # #', and a field '####' for carrying command parameters. In this embodiment, the database modification command is called, and in addition, the preset database item is "property _ list", the first database value is "system.
2043: and updating the database value corresponding to the preset database item in the preset database into a first database value through the database modification command.
The database modification command may be sent to an operating system of the terminal, and the operating system of the terminal receives the database modification command, acquires a corresponding database value from a preset database according to a preset database item carried by the database modification command, and updates the acquired database value to a first database value carried by the database modification command.
When the operating system of the terminal updates the database value corresponding to the preset database item in the preset database, the operating system of the terminal automatically sends a notification event to the application which is registered to monitor the preset database item in the preset database. The applications for registering and monitoring the preset database items in the preset database comprise a first application, so that the first application can receive the notification event, automatically acquire a first database value corresponding to the preset database item from the preset database according to the indication of the notification event, and extract the attribute name and the first attribute value included in the second attribute information from the first database value.
Optionally, the operating system of the terminal may obtain, according to the database identifier of the preset database and the preset database item, an application identifier of an application that registers and monitors the preset database item in the preset database from the correspondence between the application identifier, the database identifier, and the database item, and then send a notification event to an application corresponding to each obtained application identifier.
Among them, it should be noted that: each attribute information in the terminal may correspond to the same preset database entry in the preset database, so that the operating system of the terminal may send a notification event to other applications except the application that needs to call the first attribute information. The other application receives the notification event, acquires a corresponding first database value from a preset database according to the preset database item, and extracts an attribute name and a first attribute value included in the second attribute information from the first database value; and according to the attribute name included in the second attribute information, if the second attribute information is found not to be the attribute information which needs to be called, discarding the second attribute information.
For example, a database modification command "setting put system property _ listenersys. The operating system of the terminal receives the database modification command, acquires a corresponding database value of 0 from the preset database shown in table 1 according to a preset database item "property _ builder" carried by the database modification command, and updates the acquired database value of 0 to a first database value "sys.
TABLE 3
| Database entry | Database values |
| property_listener | sys.boot.animation＝bootnew |
| …… | …… |
Then, the operating system of the terminal obtains a corresponding application identifier APP1 from the correspondence between the application identifier, the database identifier, and the database entry shown in table 2 according to the database identifier data1 of the preset database and the preset database entry property _ builder, and sends a notification event to the first application corresponding to the application identifier APP 1.
The first application receives the notification event, obtains a first database value system, boot, animation, which corresponds to the preset database item property _ list from the preset database shown in table 3 according to the indication of the notification event, and extracts the attribute name system, boot, animation and the first attribute value boot from the first database value system, boot, animation, and the first attribute value boot, thereby obtaining the modified second attribute information.
In this embodiment, a callback program may also be set, and the callback program monitors the first attribute information, and sends a notification event to the first application that calls the first attribute information when the first attribute information is modified to the second attribute information.
And after receiving the notification event, the first application calls the modified second attribute information according to the preset attribute name.
Among them, it should be noted that: the callback program may consume no or less system resources while listening to the first attribute information.
In this embodiment, when the first attribute information is modified into the second attribute information, the database value corresponding to the preset database item in the preset database is modified into the first database value, and the first database value includes the second attribute information, so that the operating system notifies the first application registered and monitored for the preset database item in the preset database, so that the first application obtains the first database value corresponding to the preset database item from the preset database, and extracts the second attribute information from the first database value. Therefore, when the first attribute information is modified into the second attribute information, the second attribute information is immediately provided for the first application, and the first application does not need to start an attribute monitoring thread to poll the first attribute information every preset time, so that the resource consumption is reduced, and the instantaneity of the first application for acquiring the modified second attribute information is also improved.
