Abstract

The present invention provides a 3D shadow generation method on an Android television and an electronic device. The method comprises the steps of: employing a method of a content stretch boundary to add a vision boundary for a point 9 graph; identifying the vision boundary of the point 9 graph to obtain a coordinate value of a 3D shadow area and a coordinate value of a content area, wherein the content area is a vision boundary rectangular coordinate closed area; drawing the content area and the 3D shadow area, and setting the transparency of the 3D shadow area to control the visibility of the3D shadow area. The transparency of the 3D shadow area is set to achieve dynamic display of the 3D shadow effect, the vision boundary of the point 9 graph is employed to divide the 3D shadow area toachieve separation of the 3D shadow area and a content stretch area and ensure that the content stretch area cannot influence the 3D shadow area, the 3D shadow attributes have no the compatibility problem of a low-version system, and a limited area is employed for redrawing to reduce the resource waste.

Description

technical field [0001] The present disclosure relates to the application field of Android TV, in particular to a method for generating 3D shadows on Android TV. Background technique [0002] With the widespread popularity of Android smart TVs, audio and video applications on Android TVs are also growing rapidly. According to Google's official Material Design interaction specification, a View carrying content elements is defined as a card (Card), in order to improve the visual effect , Google engineers designed CardView, CardView has a variety of special effects attributes: setting rounded corners, 3D shadows, background colors, etc. Currently CardView is widely used in Android App, as follows Figure 3-1 The rectangular card with "Operation Popsicle" in it is a typical CardView. [0003] One of the most widely used special effect properties in CardView is 3D shadows, such as Figure 3-1 As shown, the shadow depth (Z-Ev) at the bottom of the card is the largest, the left and ...
