Description

A kind of framework BMVVMFramework for quickly realizing MVVM patterns

Technical field

The present invention relates to Android development fields, more particularly to a kind of framework for quickly realizing MVVM patterns BMVVMFramework。

Background technology

In Android exploitations, Activity is not the Controller in the MVC pattern of a standard, its head Want responsibility to be layout and the initialising subscriber interface of loading application, and receive and process the operation requests from user, Jin Erzuo Go out response.As the complexity of interface and its logic is constantly lifted, the responsibility of Activity classes is continuously increased, so that becoming huge It is too fat to move.When we move to wherein complicated logical process in an other class (Presneter), Activity is in fact View in MVP patterns, it is responsible for the initialization of UI elements, set up the associating of UI elements and Presenter (Listener it Class), while oneself can also process some simple logics (complicated logic transfers to Presenter process).It is specific as follows：1、 Model-View-Controller patterns (abbreviation MVC pattern), View receives event, and calls Controller to operate Model, after the data of Model examples change, Controller is updating View.2、Model-View-Presenter Pattern (abbreviation MVP patterns), View layers become a passive thing, and Presenter is responsible for completing View layers with Model layers Interaction.View cannot be interacted directly (allow Model and View to interact in MVC) with Model, and only Presenter informs it Update, it just can go to update.And the interaction of Presenter and View is completed by interface.3、Model-View- ViewModel patterns (abbreviation MVVM patterns), the event of View is directly delivered to ViewModel, and ViewModel is gone to Model Operated and received renewal.And then feed back on View.Therefore, in sum most of Android projects are all based on MVC Or MVP patterns are developed, MVC pattern benefit is exactly that the renewal of data becomes very simple, but shortcoming is also fairly obvious, Activity becomes very too fat to move, and nearly all function is all integrated into a place, later stage bad maintenance.MVP patterns are used Presenter separates feature code with Activity, but with the relation between function increase Presenter just Become to become increasingly complex, it is difficult to distinguish.

Now, small part adopts MVVM mode developments.Response type of the third-party MVVM pattern frameworks based on Rx series Programming framework, it is too high to there is learning cost, is not easy to grasp, and and non-usage can be to set up MVVM schema entries, also Oneself go the defect for encapsulating and formulating standard.

The content of the invention

In view of the above problems, it is an object of the invention to provide a kind of structure for making whole project becomes apparent from, simply, hold It is readily understood, and versatility is extremely strong, without additional studies, as long as using the project that just can at once generate a MVVM pattern Quickly realize the framework BMVVMFramework of MVVM patterns.

For achieving the above object, a kind of framework BMVVMFramework for quickly realizing MVVM patterns that the present invention is provided, Characterized in that, including the acquiescence page associated into the initialization page and the initialization page for needing load networks data list Face and with the related encapsulation page of default page, with the video data page that associates of the initialization page and with the video data page The encapsulation of association not layout page.The initialization page loads a View and points out the page, there is the state of loading data after data Then it is changed into drop-down refreshing and loads more, and obtains data and be possible to Network Abnormal and obtain less than and after data are taken back May parse and mistake or server crash occur, or only table data does not have content.The video data page is by number Data association is carried out according to view is bound after return, and incidentally clicks on event, there is defined the outlet of unified request, adjusted back Data bind view and click event automatically, return a kind of unified template, easily realize that data are bound and responded.Encapsulate not cloth Office's page is that Flushing status and List View are associated by the two-way binding technology of Databinding, easily realizes row Table handling is affected Flushing status and then asks network data to carry out the renewal of new round List View and controlled by the page and number of pages Carry out loading more data；List request data and state relation, state is also accordingly changed when network request, shape State changes the change that can be immediately associated with view.Default page be non-list need the interface of load networks data similarly with The pattern similarity of list, although implementation is inconsistent, but equally follow unified method.

In some embodiments, initialize the page loading state null data state, Flushing status, error condition, Network Abnormal state, and interaction readjustment and loading data.

The invention has the beneficial effects as follows：1st, the function that fast construction goes out MVVM schema entries is provided by the present invention, without Additional studies and encapsulation function can set up a complete MVVM schema entry, improve development efficiency.2nd, with The template of BaseViewModel is with reference to the development library for deriving a set of extremely simplicity.It is thereby achieved that making the knot of whole project Structure becomes apparent from, simply, it is readily appreciated that, and versatility is extremely strong, without additional studies, as long as using just can at once generating one The effect of individual MVVM patterns.

Description of the drawings

Fig. 1 is the distribution block diagram of the present invention.

Specific embodiment

Invention is described in further detail below in conjunction with the accompanying drawings.

As shown in figure 1, a kind of framework BMVVMFramework for quickly realizing MVVM patterns, including enter and need plus contained network The initialization page of network data list and the default page that associates of the initialization page and with the related encapsulation page of default page Face, the encapsulation associated with the video data page that associates of the initialization page and with the video data page not layout page.Initialization The page loads View and points out the page, the state for having loading data after data be then changed into drop-down refreshing and load it is more, and Obtain data be possible to Network Abnormal and obtain less than, and data take back after may parsing occur mistake or server collapse Burst, or only table data does not have content.State null data state, Flushing status, the mistake shape of initialization page loading State, Network Abnormal state, and interaction readjustment and loading data.The video data page is entered by binding view after data return Row data association, and event is incidentally clicked on, the outlet of unified request is there is defined, callback data binds view and point automatically Event is hit, a kind of unified template is returned, easily realizes that data are bound and responded.Layout page is not to pass through for encapsulation The two-way binding technology of Databinding is associated Flushing status and List View, easily realizes that list operation affects brush New state so ask network data carry out the renewal of new round List View and by the page and number of pages control carry out loading it is more Data；List request data and state relation, state is also accordingly changed when network request, and state change can be immediately It is associated with the change of view.Default page is that non-list needs the interface of load networks data similarly with the pattern phase of list Seemingly, although implementation is inconsistent, unified method but is equally followed.Fast construction is provided by the present invention go out MVVM schema entries Purpose function, without additional studies and encapsulation function a complete MVVM schema entry can be set up, and improve development efficiency.With The template of BaseViewModel is with reference to the development library for deriving a set of extremely simplicity.

In addition, alternative scheme adopts the frameworks such as RxJava, ReactiveCocoa.May be used to build MVVM patterns, but The frameworks such as RxJava, ReactiveCocoa are built and also need to carry out extra study, and without perfect encapsulation, need volume It is outer to go to adjust and improve, it is impossible to reach the simple and efficient and easy to understand of the present invention, once using MVVM patterns can be generated Project.

Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, not On the premise of departing from the invention design, some deformations and improvement can also be made, these belong to the protection domain of invention.
