Embodiment

[0026] The first step is to keep the size unit in the application consistent, all of which are dp, including the size unit used in the xml layout file and code;

[0027] In the second step, in Android, the conversion relationship between px and dp:

[0028] px=dp*density (1)

[0029] density=densityDpi / standard dpi 160 (2)

[0030] It can be seen from formula (1) that modifying the density and densityDpi of DisplayMertics can affect the final pixel value displayed on the screen. We take the screen width as the dimension and keep this dimension consistent with the design drawing.

[0031] Taking the design drawing as 1920x1080px as an example, the conversion to dp is 1280x720dp, and the width of the design drawing is 720dp. The width and height of the screen under the horizontal screen is 1080x1920px, which is adapted by the width. After adaptation, the density = the real width of the device (unit: px) / the reference width of the design drawing = 1080 / 1280 = 0.84375, densit...

Abstract

The invention relates to the field of smart television screen adaptation, in particular to a method for horizontal and vertical screen interface adaptation of a waterfall flow application on a smart television, and achieves the effect of horizontal and vertical screen adaptation under the condition that a set of vertical screen UI does not need to be additionally designed. The method for adapting the horizontal screen interface and the vertical screen interface of the waterfall flow application on the smart television comprises the steps: standardizing an internal size unit of the application, and marking the width, height and position information of a control through dp, wherein the internal size unit of the application comprises an xml layout file and a size unit used in a code; carrying out the adaptive parameter calculation according to the design drawing width and the current screen width, and keeping the dimension of the screen width consistent with the design drawing; and according to an adaptive parameter calculation result, modifying corresponding parameters in an onCreate() method of Activity to realize horizontal and vertical screen interface adaptation. The method is suitable for the horizontal and vertical screen interface adaptation of the waterfall flow application on the smart television.

Description

technical field [0001] The invention relates to the field of smart TV screen adaptation, in particular to a method for adapting a horizontal and vertical screen interface of a waterfall application on a smart TV. Background technique [0002] The interface adaptation of Android applications for horizontal and vertical screens is usually to set two sets of interface layouts for horizontal and vertical versions. When the device switches between horizontal and vertical screens, the life cycle of the application will be repeated, and the layout file in the corresponding state will be loaded according to the current screen state. [0003] The following describes two general interface adaptation methods for horizontal and vertical screens. The first method only needs to write the corresponding layout files under res / layout-land and res / layout-port, without modifying the code, the system will load the layout files under layout-land or layout-port according to the screen status; Th...
