Detailed ways

The specific embodiments of the present invention are further described in detail below with reference to the drawings and embodiments. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

Referring to FIG. 1, a communication method between multiple Fragment according to an embodiment of the present invention is provided, including: S1, configuring a message controller for all Fragment fragments in an interface, and registering all Fragments in the message controller; S2 Based on the command interface defined for each Fragment and its interface function, the message controller forwards the message of the source Fragment to the destination Fragment.

In the development process of Android, interface-related programming is usually involved. There are often multiple Fragments in an interface. Fragment can be understood as a fragment element, that is, an interface can contain multiple fragment elements. A Fragment can manage the business logic of a page. Multiple Fragments can separate and separate the business logic of each page. Communication is required between each Fragment. The traditional way is to directly communicate between Fragment, that is, the source Fragment directly sends a message to the destination Fragment. In this way of communication, if the number of Fragment is large, the communication between Fragment will be confusing; at the same time, if there is a nested reference relationship between multiple Fragments, when the top Fragment sends a message to the lowest Fragment, It needs to be forwarded layer by layer, and the communication speed is slow.

Therefore, in order to solve the above problem, the present embodiment provides a simple communication method between a plurality of Fragments. In the specific implementation process, in order to realize communication between multiple Fragment, a communication protocol for communication between multiple Fragment is designed, and subsequent Fragments follow this protocol to communicate, specifically designing between multiple Fragment The communication protocol is to define command interfaces and interface functions for each Fragment in the interface. At the same time, a message controller is configured for all the Fragments in the interface, wherein the message controller is used to control all the Fragments. In this embodiment, based on the command interface and interface function defined for each Fragment, the message controller mainly implements forwarding of messages between multiple Fragments.

In this embodiment, when a Fragment sends a message to another Fragment, for convenience of description, the Fragment that sends the message is called the source Fragment, and the Fragment that receives the message is called the destination Fragment. The source Fragment first sends a message to the message controller, and the message controller forwards the message to the destination Fragment. The destination Fragment needs to receive the message from the message controller and needs to register with the message controller. Only the Fragment registered in the message controller can receive the message forwarded by the message controller. In addition, in the process of communication between the source Fragment and the message controller and the message controller and the destination Fragment, communication is implemented based on the above communication protocol.

In this embodiment, all the Fragment configuration message managers in the interface are implemented by the message controller to implement a Fragment to send a message to another Fragment to avoid confusion of direct communication between multiple Fragments; and when between multiple Fragments When there is a nested relationship, since all the Fragments registered in the message controller in this embodiment are in a peer relationship, when the source Fragment sends a message to the destination Fragment having a nested relationship, the message controller directly forwards the message to the destination. Fragment, without the need to pass the first-level Fragment, avoids the complicated communication problems that need to be sent layer by layer.

On the basis of the foregoing embodiment, in an embodiment of the present invention, the step S2 further includes: defining a command interface for each Fragment, and defining an interface function for the command interface, where the interface function includes at least a message command word. And message body parameters.

In the process of designing a communication protocol between multiple Fragments, a set of command interfaces is designed for each Fragment. In order to be compatible with all messages, the designed communication protocol can be divided into two parts. The first part is the message command word, which is mainly used. To indicate the type of message, the second part is the message body, which is the specific content of the message. The program code of the designed command interface is as follows:

Interface indicates that the protocol is an interface protocol, IMessage indicates the name of the interface protocol; onMessage indicates the interface function contained in the interface protocol, and its return value is of type void, that is, there is no return value. The interface function contains two parameter information, one is a String (string) type command, command indicates the message command word issued, and the other parameter is the Object type message. The reason is designed as Object type to be able to All types of messages are received through this interface function.

By observing, it can be found that each parameter in the above interface function has a prefix @NoNullable, indicating that the parameter passed to the interface function cannot be null (null), in order to ensure that the parameter is not empty.

The communication interface design is described by the above programmed language, and any message can be transmitted through the command and message mode. In order to receive the message, the Fragment needs to follow the communication protocol designed above. The above programmatic representation is that the Fragment needs to inherit the IMessage interface and overwrite the onMessage method. After such processing, the fragment is a Fragment that inherits from the IMessage interface, and has the ability to receive messages sent by the IMessage interface.

In addition, the Fragment must receive the message forwarded by the message controller, and must register with the message controller. Only the Fragment registered with the message controller can receive the message distributed by the message controller. Among them, the specific registration process is: Fragment is a class, each class has a constructor, and registration is implemented in the constructor of the Fragment to ensure that the Fragment is actively registered in the message controller when it is instantiated.

The message registrar register (this.fragment) in the message controller is called in the constructor of the Fragment, and the Fragment object is registered in the message controller. Among them, all the Fragments registered in the message controller are in a peer relationship, that is, all the Fragments belong to an equal relationship, and multiple Fragments in the existing existence have a nested relationship, that is, multiple Fragments have a hierarchical relationship. In the present embodiment, this hierarchical relationship is reported by registering with the message controller, and all the Fragments registered in the message controller are in a peer relationship.

Based on the foregoing various embodiments, in another embodiment of the present invention, the step S2 further includes: maintaining, for all the Fragments registered to the message controller, a Fragment object for storing all the registrations in the message controller. Collection of objects.

After all the Fragments in the interface are registered in the message controller, a set of objects is maintained in the message controller, and the object set is mainly used to store all the Fragment registered in the message controller, so that the subsequent message controller can be like Fragment. Distribute the message.

On the basis of the foregoing various embodiments, in another embodiment of the present invention, the step S2 further includes: when the message controller receives the message sent by the source fragment, the message is broadcasted or peer-to-peer. Send to the destination Fragment.

When the message controller receives the message sent by the source Fragment and forwards it to the destination Fragment, the message controller can forward the message in two ways, one is to broadcast the message to the destination Fragment, and the other is to pass the peer-to-peer. The way to forward messages to the destination Fragment enables flexible distribution in a variety of ways.

In an embodiment of the present invention, in step S2, the step S2 further includes: when the message controller receives the message sent by the source fragment, and broadcasts the message to the Fragment registered with the message controller; The Fragment that receives the message determines whether the message needs to be processed according to the message command word in the message.

As described above, when the message controller forwards the message to the destination Fragment, it may be broadcast or peer-to-peer. When the message controller sends the message in a broadcast manner, the message controller broadcasts the message to the Fragment registered in the message controller when receiving the message of the Fragment, wherein the message includes the message command word and the message body. The Fragment that receives the message determines whether the message is a message required by itself according to the message command word in the message, and if it is a required message, acquires the message and processes it.

The specific process of the message controller broadcasting the message to the Fragment registered in the message controller is: the message controller traverses all the Fragment objects in the object set by means of a for loop, and extracts the Fragment one by one from the object set. Each time a Fragment object is extracted, the interface function onMessage in the Fragment object is called, and the message received from the Fragment of the sent message is passed to the interface function onMessage of the Fragment object, and the interface function onMessage is based on the message command word in the message. Determine whether the message needs to be processed, so that the process of sending a message to another Fragment is completed by the forwarding of the message controller.

In another embodiment of the present invention, the step S2 further comprises: the message controller receiving the message sent by the source Fragment, and forwarding the message to the destination Fragment according to the destination Fragment identifier in the message.

In the foregoing embodiment, the message controller forwards the message by means of a broadcast, and in this embodiment, the message controller forwards the message by means of a peer-to-peer. Specifically, when the message controller receives the message sent by the source Fragment, where the message includes the destination Fragment identifier that needs to send the message. The message controller forwards the message directly to the destination Fragment based on the destination Fragment identifier in the message.

Through the above two methods, it can be seen that the message delivery in the solution is forwarded by the message controller, and is not a way of direct communication between the traditional Fragment, and the design method of forwarding the message through the message controller is All the Fragments registered in the message controller are in a peer-to-peer relationship. When the source Fragment sends a message to the destination Fragment with a nested relationship, it is directly forwarded by the message controller to the destination Fragment, so that the message is sent and received with the Fragment. Hierarchical level is not related, and does not need to be passed through the first-level Fragment, avoiding the complicated communication problem caused by the need to send messages layer by layer.
