我正在构建自定义标题。当我给组件样式属性prop-'position:“ absolute”'时,可触摸不透明组件的onPress事件不起作用。但是,当我对样式属性-位置进行评论时,它可以完美地工作。我在其他地方找不到解决方案。请帮助。
<Animated.View
style={{
elevation:
params !== undefined && params.elevation !== undefined
? params.elevation
: null,
position: "absolute",
top: 0,
left: 0,
backgroundColor:
params !== undefined && params.headerBgColor !== undefined
? params.headerBgColor
: "red",
width: "100%",
height:
params !== undefined && params.changingHeight !== undefined
? params.changingHeight
: 50,
justifyContent: "space-between",
alignItems: "center",
flexDirection: "row",
paddingHorizontal: 20
}}

<TouchableOpacity style={{}} onPress={() => console.log("hello")}>
<View style={{}}>
<Image
style={styles.menuIcon}
source={require("../../assets/images/Menu-512.png")}
/>
</View>
</TouchableOpacity>
<TouchableOpacity onPress={() => console.log("image")}>
<View style={{}}>
<Image
style={styles.profImage}
source={require("../../assets/images/user.png")}
/>
</View>
</TouchableOpacity>
</Animated.View>;

您是否缺少提供条件的某些参数或条件检查为空,请确认它希望此答案对您有帮助
import * as React from 'react';
import {
Text,
View,
StyleSheet,
Animated,
TouchableOpacity,
Image,
} from 'react-native';
import Constants from 'expo-constants';
export default class App extends React.Component {
render() {
return (
<View>
<Text>Hello this is demo of flexdirection of box color</Text>
<Animated.View
style={{
position: 'absolute',
top: 0,

backgroundColor: 'red',
width: '100%',

<TouchableOpacity style={{}} onPress={() => alert("hello","hello")}>
<View style={{}}>
<Image

</View>
</TouchableOpacity>
<TouchableOpacity style={{}} onPress={() => alert("hello","hello")}>
<View style={{}}>
<Image
source={{ uri: 'https://reactjs.org/logo-og.png' }}

</View>
</TouchableOpacity>
</Animated.View>
</View>
);
}
}
您应该将absolute
放置为Animated.View
作为屏幕组件中的最后一个子元素。否则,占据屏幕其余部分的视图将成为触摸的响应者。
const Screen = () => {
return <View style={{ flex: 1}}>
<View style={{flex: 1}}>
//actual screen content
</View>
<Animated.View // header
...props
></Animated.View>
</View>
在DOM中,另一个组件之后的组件被放置在它的上方。因此,如果您执行此操作,则标题将位于实际屏幕内容视图的上方,因此在被按下时成为响应者。
