Question

我一直在尝试实现设计，但是我不知道如何正确地融合图像，我不希望图像的底部显示如下图所示

但这是我在实现后在本机中实现的时候得到的

下面是我的代码，请问我该怎么做才能正确获得设计

render() {
  return (
    <View style={{ flex: 1, backgroundColor: "#000" }}>
      <StatusBar

请检查以下代码快照，这将有助于实现上面提到的设计

我还添加了snack.expo.io

您可以根据需要更改颜色和图像。

import * as React from 'react';
import {ScrollView,Image,ImageBackground, Text, View, StyleSheet } from 'react-native';
import { Constants } from 'expo';

// You can import from local files
import AssetExample from './components/AssetExample';

// or any pure javascript modules available in npm
import { Card } from 'react-native-paper';

export default class App extends React.Component {
  render() {
    return (
      <View style={{ flex: 1,}}>


        {/* this is the picture I am trying to blend */}
        <ImageBackground
          style={{
          paddingBottom:30,
            width: "100%",
             backgroundColor:'#070707',
          flex:1
          }}
          source={require("./assets/snack-icon.png")}
          resizeMode="contain"
        >
          <View
            style={{
           height:'100%',
     alignContent:'center',
              backgroundColor: "rgba(0,0,255,0.40)",

            }}
          >
            <Image

                              alignSelf:'center',


              }}
             source={require("./assets/snack-icon.png")}

Answer 2

我后来解决了问题，但是我添加了约300行新代码，创建了20个视图并将它们的位置设为绝对，然后使它们的不透明度降低了0.02，即0.90然后是{{ 1}}，然后使它们的顶部边距减小10，即0.88然后410，一直到0.00，所以它从下到上创建了一个混合图像，然后我做了400绝对中的所有文本并也编码了它们的上边距，这并不容易，但是我明白了，这是下面的结果

这是新代码

<ImageBackground/>

混合图像背景的底部
