Method for adapting to multiple screen resolutions, storage devices and Android devices

Abstract

The invention belongs to the technical field of Android development, and in particular relates to a method for adapting multiple screen resolutions, a storage device and an Android device. The method for adapting multiple screen resolutions of the present invention includes the following steps: the service process calls the system interface to create a virtual screen and its display buffer; the service process sets the output screen to use the same display buffer as the virtual screen; the service process acquires The resolution of the virtual screen and the output screen is calculated, and the scaling parameter is calculated; the service process displays the user interface data in the display buffer on the output screen according to the scaling parameter. The technical solution of the present invention can realize that the Android application program can adapt to Android output screens with different resolutions only by providing resources and configurations of one resolution, simplify the development process, and reduce the volume of the application program at the same time.

Description

technical field [0001] The invention belongs to the technical field of Android development, and in particular relates to a method for adapting multiple screen resolutions, a storage device and an Android device. Background technique [0002] With the continuous popularization of smart devices, the market share of the Android system continues to expand, becoming the largest smart device operating system, and is adopted by a large number of mobile terminals or multimedia devices. Due to the openness of the Android system, the screen fragmentation problem of Android devices is becoming more and more serious. On the one hand, Android devices produced by various manufacturers have screens of different sizes and resolutions, such as smartphone screens of various specifications and sizes. , the screen specifications applicable to the external connection of the Android system are also different, such as LCD TVs with different resolutions and sizes. In the process of Android applica...

In the process of Android application development, we often encounter similar problems: the user interface design prepared for the 1024*768 resolution screen, running on the 1280*720 resolution screen, is likely to have a large number of left and right sides Blank; while the 1280*720 user interface is designed to run on a 1024*768 resolution device, the screen may not be able to display

[0003] The Chinese patent application number 201110176278.0 discloses a method for an Android application program to adapt to different screen densities. This method provides a resolution adaptation mechanism based on dpi (screen pixel density), and each dpi requires an application program to have a corresponding Image resources, resulting in the need to provide multiple sets of image resources for application development to adapt to various resolutions. Not only is the development process cumbersome, image resource management and maintenance are error-prone, but it will also increase the file size of the packaged application.

[0004] The Chinese patent with the application number 201310133232.X discloses a method for image adaptive resolution display. This method dynamically generates resources of the corresponding resolution through the application program to match the current resolution, but this method requires a large number of resources. The time to generate the required specification resources will also be longer, which increases the initial running time of the application, and the user experience is not good

[0005] The Chinese patent with the application number 201610164574.1 discloses a percentage-based screen adaptation method for Android mobile phones, which realizes application layout scaling by generating a ratio configuration file for each required resolution and standard resolution. The disadvantage of the method is that the new resolution cannot be automatically adapted, and the application needs to be manually generated and repackaged. At the same time, the configuration files of various resolutions also increase the file size of the application.
