我有一个菜单图标,我想保留我分配给它的特定位置它与渲染部分或其他有关。
我尝试使用我的样式表,这就是我从
中弄清楚问题的方式菜单按钮代码:
import React from 'react';
import {AppRegistry, StyleSheet, View} from "react-native" ;
import Icon from 'react-native-vector-icons/Ionicons'
import {widthPercentageToDP as wp, heightPercentageToDP as hp} from 'react-native-responsive-screen'
export default class MenuButton extends React.Component {
render() {
return(
<View >
<Icon name= "ios-menu" size={wp('12%')}
color='#9B9B9B'
style={{position: 'absolute', top: wp('-82.5%'), left: wp('-46%'), }}
onPress={() => this.props.navigation.openDrawer()} />
</View>
)
}
}
AppRegistry.registerComponent('Menu', () => FixedDimensionsBasics);
设置页面代码:
import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
import MenuButton from './MenuButton'
export default class SettingScreen extends React.Component{
render(){
return(
<View style={styles.container}>
<MenuButton navigation= {this.props.navigation}/>
<Text style={styles.text}>Settings</Text>
</View>
)
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: 'rgba(215,215,215,1)',
alignItems: 'center',
justifyContent: 'center',
},
text:{
fontSize: 30,
}
});
您必须在设置页面中更改视图顺序。最终将绝对定位的视图放置。
在菜单按钮中,您不需要在视图中包装图标。如果将图标包装在视图中,则图标将位于该视图中,而不是设置页面视图。我更改了图标的顶部和左值。
菜单按钮代码
import React from "react";
import { AppRegistry, StyleSheet, View } from "react-native";
import Icon from "react-native-vector-icons/Ionicons";
import {
widthPercentageToDP as wp,
heightPercentageToDP as hp
} from "react-native-responsive-screen";
export default class MenuButton extends React.Component {
render() {
return (
<Icon
name="ios-menu"
size={wp("12%")}
color="#9B9B9B"
style={{ position: "absolute", top: wp("5%"), left: wp("5%") }}
onPress={() => this.props.navigation.openDrawer()}
/>
);
}
}
AppRegistry.registerComponent("Menu", () => FixedDimensionsBasics);
设置页面代码
import React from "react";
import { StyleSheet, Text, View } from "react-native";
import MenuButton from "./MenuButton";
export default class SettingScreen extends React.Component {
render() {
return (
<View style={styles.container}>
<Text style={styles.text}>Settings</Text>
<MenuButton navigation={this.props.navigation} />
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: "rgba(215,215,215,1)",
alignItems: "center",
justifyContent: "center"
},
text: {
fontSize: 30
}
});
解决了它,删除AlignItems:'Center'并任命Alignself:"中心"仅对Menubutton
