react native怎么设置页面背景色?
React-Native使用渐变背景色
在 CSS 中使用渐变只需要用 linear-gradient 就可以,但是在 React-Native 项目中却不可以直接通过属性去实现,需要安装一个 react-native-linear-gradient 才可实现。
首先安装组件 react-native-linear-gradient
yarn add react-native-linear-gradient
在页面中使用
import React from 'react';
import {Text, StyleSheet, View, Dimensions} from 'react-native';
import LinearGradinet from 'react-native-linear-gradient';
export default class Home extends React.Component {
render() {
return (

);
}
}
const styles = StyleSheet.create({
content: {
justifyContent:'center',
alignItems:'center',
width:200,
height:50,
paddingLeft: 15,
paddingRight: 15,
borderRadius: 5
},
});效果:

LinearGradient的属性:
colors start/end locations
- colors
An array of at least two color values that represent gradient colors. Example: ['red', 'blue'] sets gradient from red to blue.
至少2个颜色值,用于颜色渐变。 - start
An optional object of the following type: { x: number, y: number }. Coordinates declare the position that the gradient starts at, as a fraction of the overall size of the gradient, starting from the top left corner. Example: { x: 0.1, y: 0.1 } means that the gradient will start 10% from the top and 10% from the left.
可选的对象,形式如: { x: number, y: number }。坐标宣告了渐变的开始位置。 - end
Same as start, but for the end of the gradient.
和start一样,但是渐变的结束位置。
start和end同时存在,渐变的起点和终点的连线,即使渐变的轨迹方向。
start={{ x : 0.0, y : 0.25 }}end={{ x : 0.5, y : 1.0 }} - locations
An optional array of numbers defining the location of each gradient color stop, mapping to the color with the same index in colors prop. Example: [0.1, 0.75, 1] means that first color will take 0% - 10%, second color will take 10% - 75% and finally third color will occupy 75% - 100%.
可选数组,内容是一些列数字,定义了colors中对应的每个渐变颜色的停止位置。

0.1-0.7 是颜色1和颜色2之间渐变的区域,0.7到1是颜色2和颜色3之间渐变的区域。那么还有个0-0.1区域呢?该区域是颜色1。
locations={[ 0, 0.5, 0.8]},则0-0.5是颜色1和颜色2渐变区域,0.5-0.8是颜色2和颜色3的渐变区域,而0.8-1区域的颜色是颜色3。
