LinearGradient 线性渐变

更新时间:2022-03-01 07:55:02下载pdf

简介

LinearGradient 线性渐变的主要用途是为子节点提供线性渐变效果。

代码演示

说明:详细示例可参考 LinearGradient Demo

垂直两段渐变

import React from "react"; import { View } from "react-native"; import { Rect } from "react-native-svg"; import { LinearGradient } from "tuya-panel-kit"; const dimension = { width: 200, height: 300 }; export default () => ( <View style={{ flex: 1, alignItems: "center", justifyContent: "center" }}> <View style={dimension}> <LinearGradient style={dimension} x1="0%" y1="0%" x2="0%" y2="100%" stops={{ "0%": "red", "100%": "yellow", }} > <Rect {...dimension} /> </LinearGradient> </View> </View> );

斜向三段渐变

import React from "react"; import { View } from "react-native"; import { Rect } from "react-native-svg"; import { LinearGradient } from "tuya-panel-kit"; const dimension = { width: 200, height: 300 }; export default () => ( <View style={{ flex: 1, alignItems: "center", justifyContent: "center" }}> <View style={dimension}> <LinearGradient style={dimension} x1="100%" y1="0%" x2="0%" y2="100%" stops={{ "0%": "red", "30%": "blue", "100%": "yellow", }} > <Rect {...dimension} /> </LinearGradient> </View> </View> );

面板背景渐变

import _ from "lodash"; import React from "react"; import { View } from "react-native"; import { NavigatorLayout } from "tuya-panel-kit"; import composeLayout from "./composeLayout"; import configureStore from "./redux/configureStore"; import { routers } from "./config"; export const store = configureStore(); class MainLayout extends NavigatorLayout { hookRoute(route) { return { ...route, background: { "3%": "red", "90%": "yellow", }, }; } renderScene(route, navigator) { let Scene = <View />; let schema = {}; let uiConfig = {}; const { dispatch, devInfo, dpState } = this.props; if (!_.isEmpty(devInfo)) { schema = devInfo.schema || {}; uiConfig = devInfo.uiConfig || {}; } const router = routers.find((r) => r.id === route.id); if (router && router.Scene) { const Component = router.Scene; Scene = ( <Component dpData={{ state: dpState, schema, uiConfig }} dispatch={dispatch} navigator={navigator} {...route} /> ); } return Scene; } } export default composeLayout(store, MainLayout);

API

style

容器样式。

类型 必传
ViewPropTypes.style

children

该子节点会被添加渐变效果,一般为 Rect。

类型 必传 默认值
any null

x1

起始点的 x 轴坐标。

类型 必传 默认值
string 0%

y1

起始点的 y 轴坐标。

类型 必传 默认值
string 0%

x2

终点的 x 轴坐标。

类型 必传 默认值
string 0%

y2

终点的 y 轴坐标。

类型 必传 默认值
string 100%

stops

渐变梯度停点。

类型 必传 默认值
object { ‘0%’: ‘rgb(255, 255, 255)’, ‘100%’: ‘rgb(0, 0, 0)’ }

说明:以上默认值为从左上角至左下角进行由白色至黑色的线性渐变。
