[英]React native Touch events are passing through absolute view
我正在使用 react-navigation 並且我想在工具欄中按下圖標時顯示一個視圖,我已經使用另一個組件制作了它並將組件設置為絕對顯示,問題是,所有 touchEvents 都是通過疊加視圖,我嘗試在 headerRightStyle 上設置 zIndex 和高程,即使在另一個子視圖中也是絕對視圖。 我還嘗試使用 TouchableWithoutFeedback 作為包裝器,但這也沒有解決問題。
這是我的組件
import React, { Component } from 'react';
import {
View,
Text,
UIManager,
LayoutAnimation,
Dimensions,
TouchableWithoutFeedback,
} from 'react-native';
import Icon from 'react-native-vector-icons/MaterialIcons';
const styles = {
movieFilterListContainerStyle: {
position: 'absolute',
bottom: -300,
right: -10,
height: 300,
},
};
class MovieFilter extends Component {
constructor(props) {
super(props);
this.state = {
showFilterList: false,
filterListWidth: 0,
};
this.renderFilterList = this.renderFilterList.bind(this);
this.onShowFilterList = this.onShowFilterList.bind(this);
this.calculateFilterListWidth = this.calculateFilterListWidth.bind(this);
}
componentWillMount() {
UIManager.setLayoutAnimationEnabledExperimental(true);
this.calculateFilterListWidth();
Dimensions.addEventListener('change', this.calculateFilterListWidth);
}
componentWillUpdate() {
LayoutAnimation.spring();
}
componentWillUnmount() {
Dimensions.removeEventListener('change', () => {});
}
onShowFilterList() {
const { showFilterList } = this.state;
this.setState({ showFilterList: !showFilterList });
}
calculateFilterListWidth() {
this.setState({ filterListWidth: Dimensions.get('window').width });
}
renderFilterList() {
const { showFilterList, filterListWidth } = this.state;
const { movieFilterListContainerStyle } = styles;
if (showFilterList === true) {
return (
<View
style={[
movieFilterListContainerStyle,
{
width: filterListWidth,
},
]}
>
<TouchableWithoutFeedback onPress={() => {}}>
<View
style={{
flex: 1,
backgroundColor: '#FFFFFF',
elevation: 10,
zIndex: 999999,
paddingRight: 10,
paddingLeft: 10,
paddingTop: 10,
paddingBottom: 10,
}}
>
<View
style={{
flexDirection: 'row',
position: 'relative',
justifyContent: 'space-between',
}}
>
<Text>Year</Text>
<Text>Test</Text>
</View>
<View style={{ flexDirection: 'row', position: 'relative' }}>
<Text>Rating</Text>
<Text>Test</Text>
</View>
<View style={{ flexDirection: 'row', position: 'relative' }}>
<Text>Categories</Text>
<Text>Test</Text>
</View>
</View>
</TouchableWithoutFeedback>
</View>
);
}
return null;
}
render() {
return (
<View style={{ flex: 1 }}>
<Icon name="filter-list" size={30} onPress={this.onShowFilterList} />
{this.renderFilterList()}
</View>
);
}
}
export default MovieFilter;
這是我的導航器:
const MoviesTab = createStackNavigator(
{
MovieList: MoviesScreen,
},
{
navigationOptions: ({ navigation }) => ({
headerRight: (
<View
style={{
marginLeft: 10,
marginRight: 10,
flexDirection: 'row',
flex: 1,
}}
>
<Icon
onPress={navigation.getParam('logout')}
size={30}
name="logout-variant"
color="#000000"
/>
<MovieFilter />
</View>
),
headerRightContainerStyle: {
zIndex: 20,
elevation: 20,
},
headerLeft: (
<View style={{ flex: 1, flexDirection: 'row' }}>
<SearchBar />
</View>
),
}),
},
);
添加pointerEvents
屬性。 該文件可以在這里找到http://facebook.github.io/react-native/docs/0.50/view#pointerevents添加pointerEvents
這一觀點在renderFilterList
方法
<View
style={[
movieFilterListContainerStyle,
{
width: filterListWidth,
},
]}
pointerEvents={'box-only'}
>
結果證明這是我們應用程序的問題/修復(請參閱第一個和最后一個評論):將絕對元素移動到頂視圖中的最后一個元素
當用空的TouchableWithoutFeedback
包裝時,點擊事件不能傳播到此之外
import { TouchableWithoutFeedback } from "react-native";
<TouchableWithoutFeedback>
// your component
</TouchableWithoutFeedback>
