Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Aiming at the defect that the prior art cannot change the theme layout, the embodiment of the invention provides a theme switching scheme. It can be understood that the theme switching for changing the theme layout means that the page design, the page elements, the positions of the page elements, and the like of the theme are all changed, so that the theme after the change and the theme before the change are fundamentally different in layout. For example, in a smart car control APP, a number of themes are typically provided for the user to select, such as: music themes, cartoon themes, weather themes, etc., which often adopt different design styles in order to highlight a certain function. In order to realize theme switching for changing theme layout, the theme package corresponding to each theme is preset, and the layout resource files in the theme package are called through the interface display tool class, so that the purpose of changing the theme layout is achieved.
Referring to fig. 1, a flowchart of a theme switching method according to an embodiment of the present invention is shown. The theme switching method is used for carrying out theme switching on an Android system or an Android system application.
The method comprises the following steps S101-S105.
S101: and receiving and analyzing the theme switching request to obtain a theme switching type and a theme identifier.
The theme switching request is generally initiated by a user, for example, when the user changes a theme applied to the Android system or the Android system, a target theme, which is a theme to be switched by the user, is selected or clicked on an operation interface applied to the Android system or the Android system. As in the foregoing example, it is assumed that the theme styles include a music theme, a cartoon theme, and a weather theme, and the current theme is the music theme, and if the user wants to switch to the weather theme, the user clicks the weather theme, and at this time, a theme switching request is sent. The theme switching request comprises a theme switching type and a theme identifier, wherein the theme switching type refers to theme switching for changing theme layout or theme switching for changing theme view; the topic identification refers to information that uniquely identifies the target topic, for example, the topic identification may be a topic name, a topic ID, etc., so as to indicate which target topic is to be switched, for example, the weather topic in the above example.
S102: and obtaining a theme pack corresponding to the theme identification.
Before the embodiment of the invention is executed, the theme pack also needs to be preset. The theme pack can be understood as a special APP pack, and the theme pack contains resource files and a small amount of codes related to the theme. One theme pack corresponds to one operating system or APP, and a plurality of APPs cannot share and use the same theme pack.
In the embodiment of the invention, the theme switching comprises two types of theme switching for changing the theme layout and theme switching for changing the theme view, and the theme switching for changing the theme layout needs to call the layout resource file in the theme package, so as to achieve the purpose of changing the theme layout; for theme switching for changing the theme view, the view resource file in the theme package needs to be called, so that the purpose of changing the theme view is achieved. The layout resource file comprises parameters of page design of a theme, page elements, positions of the page elements and the like; the view resource file comprises parameters such as the color and the picture of the theme.
After the theme pack is created, the theme pack may be stored locally in a terminal (e.g., a smart phone or a smart car key) where the Android system is located, or the theme pack may also be stored on the network side, and the terminal acquires the theme pack from the network side through network connection.
Therefore, in a preferred mode, the method further comprises the following steps: creating a theme pack, wherein the theme pack comprises a layout resource file and/or a view resource file; and storing the theme pack locally at the terminal where the Android system is located, or storing the theme pack at a network side. The specific way of creating the theme pack may be: inheriting an Application tool class (such as the tool class of Application) in advance, saving the related information of the theme in the Application tool class and initializing related resources of the theme, and completing creation of the theme pack.
S103: whether to change the theme layout or the theme view is determined according to the theme switching type.
S104: if the theme switching type is to change the theme layout, acquiring an interface display tool class corresponding to the theme pack, calling a layout resource file in the theme pack through the interface display tool class, calling a replacement function in an interface display tool class manager, and updating an original interface display tool class in an Android system or an Android system application into the interface display tool class calling the layout resource file in the theme pack.
If the theme switching type is determined to change the theme layout, the layout resource file in the theme pack needs to be called. In actual operation, the calling can be performed through the interface display tool class. An interface display tool class, such as Fragment (a tool class for interface display provided by the Android system), may call the layout resource file in the theme pack through Fragment. After the layout resource file is called, the original interface display tool class in the Android system or the Android system application is updated to the interface display tool class calling the layout resource file in the theme pack by calling a replacement function (e.g., Replace function) in an interface display tool class manager (e.g., fragment manager).
In a specific implementation, the interface display tool class may be obtained by creating a class loader and by means of the class loader. Therefore, in a preferred mode, the method further comprises the following steps: create a class loader (e.g., ClassLoader); and acquiring the name of the interface display tool class corresponding to the theme pack, and loading the interface display tool class with the name corresponding to the theme pack by using the class loader. In order to display the tool class by using the class loader loading interface, a calling interface of the resource loading tool class needs to be provided, so that in a preferred embodiment, the method further includes: modifying an interface display tool class and an interface display tool class manager of an Android system or an Android system application in advance, thereby providing a calling interface of a resource loading tool class; and the class loader loads the interface display tool class with the corresponding name of the theme pack through the calling interface of the resource loading tool class.
S105: and if the theme switching type is to change the theme view, acquiring the view resource file in the theme pack, calling a view switching function, and updating the original view resource file in the Android system or the Android system application to the view resource file acquired from the theme pack.
And when the theme switching type is a theme change view only related to resource change (color and picture), replacing the view resource file of the original interface by calling the view resource file in the theme pack. Specifically, the interface can be refreshed by calling a View-related interface. For example, when a theme switching function in View is called, the function may obtain a corresponding resource name according to the resource ID, and then obtain a resource corresponding to the theme pack according to the name, for example: pictures, colors, etc. And calling a View switching function of View to realize resource replacement and refreshing.
Referring to fig. 2, a flowchart of a theme switching method according to another embodiment of the present invention is shown. In this embodiment, the logical relationship of each step is described in detail, and the details of implementation of the topic switching type branch that changes the topic layout are described in detail.
S201: and receiving a theme switching request initiated by a user, and analyzing the theme switching request to acquire related information of a switching theme.
The related information of the switching theme at least comprises a theme switching type and a theme identifier, wherein the theme switching type indicates whether the theme layout or the theme view is changed, and the theme identifier can be a theme name or a theme ID.
S202: and detecting whether the current Android system or APP supports the theme or not according to the theme identifier, if not, ending, and prompting the user that the theme is not supported. If so, the next operation is carried out.
The theme supported by the Android system APP can be listed on a user setting interface, and the user can select different themes according to own preference. For example: musical themes, weather themes, cartoon themes, etc.
S203: according to the theme identification, obtaining the theme pack and performing initialization work of related resources, for example: creating a view resource class (such as ISCRResource) or a class loader (such as ClassLoader), and informing Activity (a tool class provided by Android, which is an entry of each interface and is a component in APP) to do relevant interface refreshing work.
After the theme pack is obtained, a corresponding resource management class (such as ISCSResource and ClassLoader) is initialized according to the theme pack and points to a path where the theme pack resources are located, and when the tool class is called, the tool class obtains related resources for the used path.
S204: and judging whether the user switches the type of the theme, namely only changing the theme view or changing the theme layout. If it is a change of the subject layout, the branches S205-S207 are executed, and if the subject view is changed, the branch S208 is executed.
S205: and acquiring the name of the corresponding SCFragment in the theme pack.
S206: and loading the SCFragment with the corresponding name by using ClassLoader, acquiring an object of the SCFragment, and calling the corresponding resource file in the theme package in the SCFragment.
S207: call replace function of fragment manager in Activity to replace SCfragment.
S208: and calling a View related interface to refresh the interface. For example, when a theme switching function in View is called, the function may obtain a corresponding resource name according to the resource ID, and then obtain a resource corresponding to the theme pack according to the name, for example: pictures, colors, etc. And calling a function of setting resources of the View to realize resource replacement and refreshing.
S209: and completing theme switching and presenting a brand new display interface for the user.
