Embodiment Construction
[0066] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0067] The present invention mainly adopts a technology of single instance and single overdrawing of the focus background to solve the defects existing in the existing focus background generation process. Its specific design idea is:
[0068] 1. Solve the problem that the focus view becomes larger as the focus background is enlarged through the single instance technology, thus occupying too much screen space. Single instance means that the focus background and the focus view no longer exist as a whole, and the two are separated from each other. Since the focus background and the focus view implement split management, even if the focus background is enlarged, the focus view will not be enlarged accordingly, and the screen space occupied by the focus view will not be increased.
[0069] 2. Solve the problem of excessive memory space o...

The invention discloses a focus background generation method, a storage medium, a device and a system of Android TV, which relate to the technical field of Android TV development. The method comprisesthe following steps of: locating the initial spatial position of the focus background and determining the initial size of the focus background; when the view group is drawn for the first time, the focus background is drawn according to the initial spatial position and the initial size of the focus background. Judging whether the focus background needs to be shifted according to the change of thefocus view; if the shift is needed, the focus background is set to be invisible, and the focus background is shifted according to the spatial position coordinates of the current focus view, and the focus background is set to be visible after the shift is completed; if no offset is required, the focus background is destroyed when the view group is no longer displayed in the interface window. The invention makes the focus view not occupy too much screen space with the magnification of the focus background, and does not have the problem of occupying too much memory space due to the excessive number of the focus background.
Description
technical field [0001] The present invention relates to the technical field of Android TV development, and specifically relates to a focus background generation method, storage medium, device and system for Android TV. Background technique [0002] With the rapid development of smart TVs and Android operating systems, Android TVs have become increasingly popular and sought after by more and more people. The so-called Android TV, as the name suggests, is a TV equipped with the Android operating system (Android), which makes the TV intelligent, and allows the TV to browse web pages, watch videos and movies, chat, office games, etc. [0003] In order to facilitate the reader's understanding, the relevant terms are briefly explained below: [0004] View (view): it is the basic component unit of Android system application layer interface visualization; [0005] ViewGroup (view group): it is the basic container unit of the Android visual component View, which can accommodate mul...
