Abstract
Description
Technical Field
[0001] The present invention relates to the field of computer technology, and in particular to an optimization method and system for displaying list item data based on a RecyclerView control. Background Art
[0002] In Android application development, the data display of list items is mainly realized through the RecyclerView control. The RecyclerView control supports multiple layout managers and animation effects. The steps to display the data of list items through the RecyclerView control are as follows:
[0003] 1. Define the XML layout file of the list items. If it is a multi-style list, define the XML layout files of multiple style list items;
[0004] 2. Define the data structure used to display the data of the list items. If it is a multi-style list, the data structure needs to include all the data fields required by the list items, and also define the list item type corresponding to each list item;
[0005] 3. Create a list adapter class that inherits RecyclerView.Adapter and implements the ViewHolder implementation class corresponding to each list item style inherited from RecyclerView.ViewHolder;
[0006] 4. Define and configure the Adapter and LayoutManager of the RecyclerView control on the page where the list item data needs to be displayed;
[0007] 5. Set the data of the list items obtained in the page to the defined Adapter to display the data of the list items.
[0008] Each RecyclerView control needs to repeat the above five steps when displaying the data of list items. That is, repeated code writing is required, which is inefficient. The data structure of the multi-style list must contain the data fields required by all list items, which will make the data structure bloated and difficult to maintain, and affect the stability of the program. Summary of the Invention
[0009] The technical problem to be solved by the present invention is: the present invention provides an optimization method and system for displaying list item data based on the RecyclerView control, which solves the bloated problem of the data structure of multi-style lists and improves the stability of the program and the reuse rate of the code.
[0010] In order to solve the above technical problems, the technical solution adopted by the present invention is:
[0011] In a first aspect, the present invention provides an optimization method for displaying list item data based on a RecyclerView control, comprising:
[0012] Construct a business data layer in the list item adapter and list item UI layer of the RecyclerView control, define a first interface and a second interface in the business data layer, and associate the first interface with the second interface, where the first interface is an independent data structure of the list item and the second interface is the basic behavior of the list item of the RecyclerView control;
[0013] In the business data layer, based on the abstract class of the RecyclerView control, a first abstract class that inherits the second interface is defined, where the first abstract class is a UI for a list item of the RecyclerView control, and the first abstract class includes a subtype of the first interface and a subtype of ViewBinding;
[0014] In the list item adapter, a reflection method is used to automatically query and create an instance corresponding to the UI of the list item of the RecyclerView control, so as to display the data of the list item.
[0015] The beneficial effects of the present invention are as follows: by constructing a business data layer in the list item adapter and the list item UI layer of the RecyclerView control, that is, isolating the list adapter from the list item UI layer, bridging through the business data layer, achieving high decoupling, defining a first interface and a second interface in the business data layer, and associating the first interface and the second interface, that is, associating the independent data structure of the list item of the RecyclerView control with the basic behavior of the list item, so that the independent data structure of the list item focuses on the data of a single list item, is no longer a bloated data structure, and improves the stability of the program, based on an inherited second interface defined by the abstract class of the RecyclerView control The first abstract class, that is, defines the UI of the list items of the RecyclerView control, and automatically queries and creates instances corresponding to the UI of the list items of the RecyclerView control through the list item adapter, thereby realizing the display of data list items. That is, the data display of the list items is liberated from the tedious work, so that the focus of the final list item data display is on the data type and UI, without having to pay attention to the style type of the list item, nor how the list item UI is associated with the ViewHolder implementation class and the list adapter of RecyclerView.Adapter. When the data type remains unchanged, it can be migrated and reused at any time, thereby improving the code reuse rate.
[0016] Optionally, the basic behavior of the list items of the RecyclerView control includes N lifecycle methods, and different lifecycle methods are used to perform corresponding operations at different stages.

The third abstract interface calls the second interface according to the position of the list item of the RecyclerView control to operate the data of the list item of the RecyclerView control and the UI corresponding to the data, so as to display the data of the list item.
[0021] Optionally, the first abstract interface obtains a position of a data list item, and obtaining a view type through the position includes:

[0023] According to the above description, the hash value corresponding to the name of the list item is used as the type identifier of the view type, and the specific embodiment of the implementation class of the second interface corresponding to the list item is cached according to the type identifier to ensure the accuracy of the query and application of the specific embodiment. At the same time, the SparseArray data structure is used for caching to facilitate subsequent queries and improve query efficiency.

[0029] Optionally, the first basic adapter stores general code of the RecyclerView control.
[0030] According to the above description, the common code of the RecyclerView control is stored in the first basic adapter for the business data layer, which solves the problem of duplicate code in the traditional RecyclerView control when implementing data display of list items and improves the code reuse rate.
[0031] Optionally, the defining of a first basic adapter oriented to the business data layer based on the list item adapter is directly defined in a display page corresponding to the data of the list item.

[0046] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Instead, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.
[0047] Example 1
[0048] Please refer to Figures 1 to 2 The present invention provides an optimization method for displaying list item data based on a RecyclerView control, comprising the steps of:
[0049] S1. Build a business data layer in the list item adapter and list item UI layer of the RecyclerView control, define a first interface and a second interface in the business data layer, and associate the first interface with the second interface. The first interface is an independent data structure of the list item, and the second interface is the basic behavior of the list item of the RecyclerView control.
[0050] In this embodiment, if Figure 2 As shown, a business data layer is constructed in the list item adapter and list item UI layer of the RecyclerView control, that is, a business data layer is added to the RecyclerView.Adapter and RecyclerView.ViewHolder layers, and a first interface and a second interface are defined in the business data layer. The first interface is an independent data structure of the list item, and the second interface is the basic behavior of the list item of the RecyclerView control. The basic behavior includes N lifecycle methods. Different lifecycle methods are used to perform corresponding operations at different stages. The first interface is associated with the second interface, that is, the independent data structure of the list item is associated with the basic behavior of the list item, so that the independent data structure of the list item focuses on the data of a single list item.
[0051] In a specific embodiment, the first interface may be defined as: IVhProxy interface, and the second interface may be defined as: IViewHolder interface.
[0052] S2. Define a first abstract class that inherits the second interface in the business data layer based on the abstract class of the RecyclerView control, where the first abstract class is a UI for a list item of the RecyclerView control, and the first abstract class includes a subtype of the first interface and a subtype of ViewBinding;
[0053] In this embodiment, if Figure 2 As shown, in the business data layer, a first abstract class that inherits the second interface is defined based on the abstract class of the RecyclerView control, that is, a UI of a list item of the RecyclerView control that inherits the second interface is defined, wherein the UI includes UI style and view behavior. Since the abstract class of the RecyclerView control itself is an abstract class definition, a functional code encapsulation of a first abstract class that inherits the second interface is provided by abstractly implementing the unified public functions of the abstract class of the RecyclerView control, and the first abstract class includes a subtype of the first interface and a subtype of ViewBinding. Therefore, the first abstract class can automatically associate the first interface with the second interface.
[0054] In a specific embodiment, the first abstract class can be represented as: AbsVhProxy<T:IVhProxy,VB:ViewBinding> :IViewHolder <t>An abstract class, where IVhProxy represents the first interface, IViewHolder represents the second interface, T represents a data list list of data types, and VB represents an instance corresponding to the XML layout of the list item.
[0055] S3. Automatically query and create an instance corresponding to the UI of the list item of the RecyclerView control in the list item adapter by reflection, so as to display the data of the list item.
[0056] In this embodiment, if Figure 2 As shown, reflection is used in the list item adapter to automatically query and create instances corresponding to the UI of the list items of the RecyclerView control. Since the data types are limited, this embodiment processes the data types. The limited data types can be added with the UI styles that need to be supported, and one data type can correspond to multiple UI styles.
[0057] In a specific embodiment, the first abstract class is: AbsVhProxy<T:IVhProxy,VB:ViewBinding> :IViewHolder <t>When the class is abstract, the list item adapter is AbsAdapter <t:ivhproxy>, in the list item adapter: AbsAdapter <t:ivhproxy>In the internal, reflection is used to automatically query and create the instance corresponding to the UI of the list item of the RecyclerView control, and IViewHolder is used <t>The class full path name hashCode is automatically cached as the ItemViewType value to avoid repeated creation.
[0058] At this time, step S3 includes:
[0059] S31. Acquire a first abstract interface, a second abstract interface, and a third abstract interface;
[0060] In this embodiment, the first abstract interface is getItemViewType, the second abstract interface is onCreateViewHolder, and the third abstract interface is onBindViewHolder.
[0061] S32. The first abstract interface obtains the position of the list item of the RecyclerView control, and obtains the view type through the position of the list item of the RecyclerView control. The second abstract interface obtains the corresponding proxy class according to the view type, and traverses the parent class of the proxy class to filter out the parent class that meets the subtype of the ViewBinding, obtains the generic parameters of the filtered parent class, creates an instance of the proxy class according to the generic parameters by reflection, and returns the instance of the proxy class to the UI of the list item of the RecyclerView control. The third abstract interface calls the second interface according to the position of the list item of the RecyclerView control to operate the data of the list item of the RecyclerView control and the UI corresponding to the data, so as to display the data of the list item.
[0062] In this embodiment, if Figure 2 As shown, the first abstract interface, namely, getItemViewType, obtains the position of the list item of the RecyclerView control, and further obtains the view type through the obtained position. The second abstract interface, namely, onCreateViewHolder, obtains the corresponding proxy class according to the view type obtained by the first abstract interface, and traverses the parent class of the proxy class to filter out the parent class of the subtype that conforms to ViewBinding, obtains the generic parameters of the filtered parent class, and calls the inflate method by reflection to generate an instance of the proxy class according to the generic parameters, and calls the method of the second abstract interface to return the instance of the proxy class to the UI of the list item of the RecyclerView control. The third abstract interface, namely, onBindViewHolder, calls the second interface according to the position of the list item to operate the data of the list item of the RecyclerView control and the UI corresponding to the data, so as to display the data of the list item.
[0063] At this time, in step S32, the first abstract interface obtains the position of the data list item, and obtaining the view type through the position includes:
[0064] S321. Obtain the name of the list item of the RecyclerView control, and perform hash calculation on the name of the list item of the RecyclerView control to obtain a hash value, use the hash value as the type identifier of the view type, and use a SparseArray data structure to cache a specific embodiment of the implementation class of the second interface corresponding to the list item of the RecyclerView control according to the type identifier.
[0065] In this embodiment, if Figure 2 As shown, when the first abstract interface obtains the view type, it also calculates the hash value of the name of the obtained list item, uses the hash value as the type identifier of the view type, and uses the SparseArray data structure to cache the specific embodiment of the implementation class of the second interface corresponding to the list item according to the type identifier.
[0066] At this time, step S3 includes:
[0067] S33. Define a first basic adapter and a second basic adapter for the business data layer based on the list item adapter. The first basic adapter provides synchronous UI thread data updates, and the second basic adapter provides asynchronous data difference calculation and local data updates using the DiffUtil solution.
[0068] S34: Display the data of the list item according to the first basic adapter and the second basic adapter.
[0069] In this embodiment, if Figure 2 As shown, based on the list item adapter, a first basic adapter and a second basic adapter for the business data layer are defined, that is, a basic adapter that provides synchronous UI thread update data: BasicAdapter, and a basic adapter that provides asynchronous data difference calculation using the DiffUtil solution for local update data: BasicDiffAdapter, that is, based on the list item adapter: AbsAdapter <t:ivhproxy>Provide implementation of BasicAdapter <t:ivhproxy>and BasicDiffAdapter <t:ivhproxy>A basic general implementation, wherein the first basic adapter stores the general code of the RecyclerView control, and when defining the first basic adapter, it can be defined directly in the display page corresponding to the data of the list item, and the data of the list item is displayed according to the first basic adapter and the second basic adapter.
[0070] At this time, step S34 includes:
[0071] S341: Based on the list item adapter, define a third basic adapter and a fourth basic adapter for the business data layer, wherein the third basic adapter is a universal adapter for list item selection, and the fourth basic adapter is a universal adapter for responsive list display that responds to window size changes.
[0072] S342: Display the data of the list items according to the first basic adapter, the second basic adapter, the third basic adapter, and the fourth basic adapter.
[0073] In this embodiment, if Figure 2 As shown, a third basic adapter and a fourth basic adapter for the business data layer are defined based on the list item adapter, that is, a general adapter for list item selection function: SelectionWrapperAdapter and a general adapter for responsive list display that responds to window size changes: WindowSizeWrapperAdapter are defined. The data of the list items is displayed according to the first basic adapter, the second basic adapter, the third basic adapter and the fourth basic adapter.
