Lockscreen Wallpaper Orientation Control via Transparent Window
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lockscreen technologies on Android devices limit display effects and interactivity by only allowing static or dynamic wallpapers with limited user engagement when the screen is locked, as they do not adapt to device orientation changes.
Innovation Solution
A lockscreen display control method and device that uses a lockscreen service to draw a transparent window, creates an activity instance with 'always on top' attributes, and monitors device orientation to dynamically adjust and switch wallpapers based on orientation parameters, enhancing interactivity and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static or dynamic wallpapers are used on lockscreen, then the display can show background images, but the interactivity and user engagement are limited
Solution Approach 1:
The wallpaper display is transformed from a static state to a dynamic state by continuously monitoring device orientation changes and automatically switching wallpapers in response to orientation events, making the lockscreen adaptable to user interactions without requiring complex application logic
Solution Approach 2:
The system monitors device orientation and automatically switches wallpapers without requiring user intervention or complex control logic, allowing the lockscreen to enhance interactivity through self-monitoring and automatic response to orientation changes
2Adaptability or versatility
If the lockscreen wallpaper process is launched with activity instance, then the wallpaper can be dynamically controlled, but the system resource consumption increases
Solution Approach 1:
Instead of continuously monitoring orientation, the system uses periodic event-driven updates by registering for orientation change events, which only trigger wallpaper switching when actual orientation changes occur, thereby reducing unnecessary processing and energy consumption
Solution Approach 2:
The activity instance maintains a continuous listening state for orientation events, ensuring the wallpaper can respond immediately to any orientation change while the system remains in a low-power state between events, balancing responsiveness with energy efficiency

AI summary
The present disclosure relates to a lockscreen display control method and device, and a storage medium. The method is applied to an electronic device and includes: when the electronic device has a bright screen in a lockscreen state, a transparent lockscreen window is drawn by using a lockscreen service, and a lockscreen wallpaper process is launched (101); an activity instance of the lockscreen wallpaper process is created, and an attribute of the activity instance is set to be always on top (102); a device orientation of the electronic device is monitored by using the activity instance to acquire an orientation parameter (103); and according to the orientation parameter, a wallpaper displayed under the lockscreen window is adjusted, and the wallpaper is controlled to dynamically display under the lockscreen window (104).
