css - 如何在标题中添加图像而不是图标反应原生元素

Question

我正在使用 react native elements Header 来显示我的抽屉，我面临两个问题：1）我的抽屉没有覆盖整个顶部（标题区域）。（可以在图片中看到蓝色不覆盖整个标题） 2）如何添加图像而不是图标，因为我不想使用 react-native-vector-icons 以及如何在该图像上添加 onPress() 方法，基本上我想添加 onPress openDrawer 的自定义抽屉图像。

这是我的代码：

import React, { Component } from 'react';
import { StyleSheet, Text, View,Image,TouchableOpacity, Alert } from 'react-native';
import Timeline from 'react-native-timeline-flatlist';
import {Header} from 'react-native-elements';
export default class HomeTimeTable extends Component {
  render() {
    //'rgb(45,156,219)'
    return (
      <View style={styles.container}>
      <Header
  placement="left"
  leftComponent={{ icon: 'menu', color: '#fff' }}
  centerComponent={{ text: 'MY TITLE', style: { color: '#fff' } }}
  rightComponent={{ icon: 'home', color: '#fff' }}
/>
        <Timeline
          ...
        />
      </View>
    );
  }
}

这是我的样式表：

const styles = StyleSheet.create({
  container: {
    flex: 1,
    padding: 20,
    backgroundColor: 'white',
  },
  list: {
    flex: 1,
    marginTop: 20,
  },
  drawer:{
      width:20,
      height:20,
      justifyContent:"flex-start",
  }
});

下面的代码应该可以工作。

import React, { Component } from 'react';
import { StyleSheet, Text, View,Image,TouchableOpacity, Alert, Image } from 'react-native';
import Timeline from 'react-native-timeline-flatlist';
import {Header} from 'react-native-elements';
export default class HomeTimeTable extends Component {

  const renderCustomIconA = () => {
    return(
      <TouchableOpacity onPress={() => {console.log('A Pressed!')}}>
        <Image
          style={{width: 50, height: 50}}
          source={{uri: 'https://reactnative.dev/img/tiny_logo.png'}}
         />
       </TouchableOpacity>
    );
  };

  const renderCustomIconB = () => {
    return(
      <TouchableOpacity onPress={() => {console.log('B Pressed!')}}>
        <Image
          style={{width: 50, height: 50}}
          source={{uri: 'https://reactnative.dev/img/tiny_logo.png'}}
         />
       </TouchableOpacity>
    );
  };

  render() {
    //'rgb(45,156,219)'
    return (
      <>
        <Header
          placement="left"
          leftComponent={() => renderCustomIconA()}
          centerComponent={{ text: 'MY TITLE', style: { color: '#fff' } }}
          rightComponent={() => renderCustomIconB()}
        />
        <View style={styles.container}>
          <Timeline
          ...
          />
        </View>
      </>

    );
  }
}
