Abstract
Description
Technical Field
[0001] This invention relates to the field of computer technology, and more specifically to an Activity launch method, an Activity launch device, a machine-readable storage medium, and a processor. Background Technology
[0002] Activity is one of the four most basic and common components in the Android system. An Activity provides a screen that offers users an interactive interface.
[0003] When a user launches an app, the program correspondingly starts launching Activities. When a user opens an app, especially for the first time after booting up, since the app has never been launched before, the process will load many time-consuming resources, especially View resources. When our View hierarchy is complex, Android will take a long time to draw the View. Users may feel that the interface is too slow to display, or even experience a white screen, which seriously affects the user experience.
[0004] Therefore, the existing Activity launch method suffers from slow interface startup. Summary of the Invention
[0005] The purpose of this invention is to provide an Activity launch method, an Activity launch device, a machine-readable storage medium, and a processor. This Activity launch method avoids loading many time-consuming View resources during startup, improves loading speed, and makes the interface launch faster, thereby giving users a fast startup experience in terms of perception and vision.
[0006] To achieve the above objectives, embodiments of the present invention provide an Activity launch method, including:
[0007] In response to an Activity launch request, load the first View resource in the Activity;
[0008] After the first View resource is loaded, the second View resource in the Activity is loaded to complete the Activity startup.
[0009] In this embodiment of the application, loading the second View resource in the Activity includes:
[0010] Start loading the second View resource in the Activity;
[0011] Once the second View resource has finished loading, add the second View resource to the ContentView.
[0012] In this embodiment of the application, the step of initiating the loading of the second View resource in the Activity includes:
[0013] The onFirstDrawFinish function is called, and within the onFirstDrawFinish function, the onDrawSecondView function is called to begin loading the second View resource in the Activity.
[0014] In this embodiment of the application, adding the second View resource to the ContentView includes:
[0015] Add the loaded second View resource to the ContentView using addView.
[0016] In this embodiment of the application, loading the first View resource in the Activity includes:
[0017] The first View resource in the Activity is loaded using the setContentView function.
[0018] In this embodiment of the application, it also includes:
[0019] Divide the Views in the Activity into primary load Views and secondary load Views;
[0020] The primary loaded View is used as the first View resource;
[0021] The secondary loaded View is used as the second View resource.
[0022] In this embodiment of the application, loading the second View resource in the Activity after the first View resource has been loaded includes:
[0023] By listening to the drawing event of the first View resource, the second View resource in the Activity is loaded after the first View resource is drawn.
[0024] A second aspect of this application provides an Activity launching device, comprising:
[0025] The first loading module is used to load the first View resource in the Activity in response to the Activity startup request;
[0026] The second loading module is used to load the second View resource in the Activity after the first View resource has been loaded, so as to complete the Activity startup.
[0027] A third aspect of this application provides a processor configured to execute the Activity launch method described above.
[0028] A fourth aspect of this application provides a machine-readable storage medium storing instructions that, when executed by a processor, configure the processor to perform the Activity launch method described above.
[0029] The beneficial effects of this invention are:
[0030] In response to an Activity launch request, the first View resource in the Activity is loaded, followed by the second View resource to complete the Activity launch. This ensures that View resources are loaded in stages while maintaining absolute optimization of the View hierarchy, achieving distributed View loading. During the loading process, because the first View resource is loaded first, loading many time-consuming View resources at launch is avoided, improving loading speed and making the interface launch faster. This provides users with a faster launch experience both perceptually and visually.

[0041] Please refer to Figures 1-2 , Figure 1 This illustration schematically shows a flowchart of an Activity launch method according to an embodiment of this application. Figure 2 The flowchart illustrating the Activity launch function call according to an embodiment of this application is shown.
[0042] The Activity launch method includes the following steps:
[0043] Step 210: In response to the Activity launch request, load the first View resource in the Activity; in this embodiment, when the user launches the APP and starts the main interface, the Activity launch request is obtained. The first View resource may include one or more Views, which may be pre-planned Views intended to be displayed to the user first.
[0044] In some embodiments, loading the first View resource can be done using the existing Activity loading mechanism, specifically by loading the first View resource in the Activity using the `setContentView` function. The purpose of `setContentView` is to place the layout file in the Activity for display. It loads the View above the root view, so when displaying views, the root view is displayed first, followed by child views, and so on, until all views are displayed. Using `setContentView` to load the first View resource helps ensure that the views within that first View resource are displayed correctly.
[0045] Step 220: After the first View resource is loaded, the second View resource in the Activity is loaded to complete the Activity launch. In this embodiment, the second View resource can be any View other than the View in the first View resource. It should be noted that the first View resource and the second View resource can be planned according to actual needs.
[0046] In some embodiments, when the View hierarchy is complex, the Views can be prioritized to obtain first View resources and second View resources. Specifically, this includes the following steps:
[0047] First, divide the Views in the Activity into primary loading Views and secondary loading Views;
[0048] Then, the primary loaded View is used as the first View resource; the secondary loaded View is used as the second View resource.
[0049] In this embodiment, the division of Views in the Activity can be based on hierarchy. For example, the highest-level View can be loaded first, and other Views can be loaded second. By dividing the Views, the loading of Views can be distributed, avoiding the problem of long loading times when loading all Views at once.
[0050] In some embodiments, the loading of the second View resource can be accomplished using a delayed loading scheme, specifically, the second View resource is loaded after the first View resource has been loaded. The determination of whether the loading of the first View resource is complete can be made using event listening. That is, loading the second View resource in the Activity after the first View resource has been loaded includes: listening to the drawing event of the first View resource, and loading the second View resource in the Activity after the first View resource has been drawn. The delay ensures that loading begins only after the first View resource has completed its layout. Using event listening ensures that loading of the second View resource begins only after the first View resource has been loaded, thus guaranteeing a delayed loading of the second View resource.
[0051] In some embodiments, the loading of the second View resource can be achieved using a dynamic loading scheme. The steps for loading the second View resource in the Activity are as follows:
[0052] First, the loading of the second View resource in the Activity is initiated. Specifically, during the loading process, the `onFirstDrawFinish` function can be called, and within `onFirstDrawFinish`, the `onDrawSecondView` function is called to begin loading the second View resource in the Activity. After the first View resource is loaded, a callback to the `onFirstDrawFinish` function is invoked, where the `onDrawSecondView` function is called. In this embodiment, the `onFirstDrawFinish` function is used to confirm the completion of loading the first View resource, and the `onDrawSecondView` function is used to load the second View resource.
[0053] Then, once the second View resource has finished loading, it is added to the ContentView. This can be done by adding the loaded second View resource to the ContentView using the `addView` function. `addView` allows for dynamic loading of Views.
[0054] In some embodiments, the loading of the second View resource can also be achieved using a delayed + dynamic loading scheme. Specifically, it can be achieved by listening to the drawing event of the first View resource, loading the second View resource after the first View resource has been drawn, and finally loading the second View resource into the ContentView using the addView method. This achieves a delayed + dynamic loading scheme, which allows the Activity to prioritize the display of the first View resource, giving users a fast startup experience in terms of perception and visuals.
[0055] For example, such as Figure 2 As shown, after the user launches the APP, the main interface starts. First, the first View resource is loaded, namely S1 in the figure. After the first View resource is completed, the onFirstDrawFinish function is called. In this function, the onDrawSecondView function is called to start loading the second View resource. Finally, the loaded View is added to the ContentView through addView and presented to the user.
[0056] In the above implementation, by responding to the Activity launch request, the first View resource in the Activity is loaded, followed by the second View resource, to complete the Activity launch. This ensures that View resources are loaded step-by-step with absolute optimization of the View hierarchy, achieving distributed View loading. During the loading process, since the first View resource is loaded first, loading many time-consuming View resources at launch is avoided, improving loading speed and making the interface launch faster, thus providing users with a fast-starting experience both perceptually and visually. By hierarchically dividing the Views into primary and secondary loadable Views, the Activity can prioritize displaying necessary Views, facilitating flexible control over the display order of Views for application in various scenarios.
[0057] Figure 1 This is a flowchart illustrating the Activity launch method in this embodiment. It should be understood that, although... Figure 1 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 1At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.
[0058] In one embodiment, such as Figure 3 As shown, Figure 3 This schematically illustrates a structural block diagram of an Activity launching device according to an embodiment of the present application. An Activity launching device is provided, including a first loading module 410 and a second loading module 420:
[0059] The first loading module 410 is used to load the first View resource in the Activity in response to the Activity startup request;
[0060] The second loading module 420 is used to load the second View resource in the Activity to complete the Activity startup.
[0061] In the above implementation process, the first loading module 410 responds to the Activity launch request by loading the first View resource in the Activity, and the second loading module 420 loads the second View resource in the Activity to complete the Activity launch. This ensures that View resources are loaded step by step while maintaining absolute optimization of the View hierarchy, achieving distributed View loading. During the loading process, since the first View resource is loaded first, loading many time-consuming View resources at startup is avoided, improving loading speed and making the interface launch faster, thus providing users with a fast-starting experience both perceptually and visually. By dividing the View hierarchy into primary and secondary loaded Views, the Activity can prioritize displaying necessary Views, facilitating flexible control over the display order of Views for application in various scenarios.
[0062] The Activity launch device includes a processor and a memory. The first loading module 410 and the second loading module 420 are stored in the memory as program units, and the processor executes the program modules stored in the memory to implement the corresponding functions.

The non-volatile storage medium A06 stores an operating system B01 and a computer program B02. The internal memory A03 provides an environment for the operation of the operating system B01 and the computer program B02 stored in the non-volatile storage medium A06. The network interface A02 is used for communication with external terminals via a network connection. When the computer program is executed by the processor A01, it implements an Activity launch method. The display screen A04 can be a liquid crystal display (LCD) or an e-ink display. The input device A05 can be a touch layer covering the display screen, buttons, a trackball, or a touchpad mounted on the computer device casing, or an external keyboard, touchpad, or mouse.
