我正在尝试弹出一个对话框(创建为一个位置为'absolute'的组件),并在用户在弹出窗口外点击时关闭它。
我是React Native的新手,所以我做的其他事情可能是错的,原谅我:)
这是一些代码:
来自Popup组件:
render() {
if (!this.props.open) {
return <View />
}
return (
<View style={styles.container}>
<View style={styles.popupStyle}>
<View style={{flex:1, justifyContent: 'center', marginRight: 10}}>
<View style={styles.amountEnterStyle}>
<TextInput
keyboardType={'numeric'}
underlineColorAndroid='transparent'
autoCorrect={false}
style={styles.textInputStyle}
value={this.state.amount}
onChangeText={this._onAmountEnter.bind(this)} />
<Text style={styles.currencyTextStyle}>NIS</Text>
</View>
<View style={styles.separatorStyle} />
<View style={styles.categorySectionStyle}>
{this._renderCategoryDropdown()}
</View>
</View>
<View style={{justifyContent: 'center'}}>
<TouchableWithoutFeedback
onPress={this._onAddPaymentClicked.bind(this)} >
<View style={{width: 110, height:100, backgroundColor: "#ff0000"}} />
</TouchableWithoutFeedback>
</View>
</View>
</View>
);
const styles = StyleSheet.create({
container: {
position: 'absolute',
top: 0,
bottom: 0,
left: 0,
right: 0,
width: undefined,
height: undefined,
justifyContent: 'center',
alignItems: 'center',
},
amountEnterStyle: {
justifyContent: 'center',
alignItems: 'center',
flexDirection: 'row'
},
textInputStyle: {
width: 100,
fontSize: 50,
fontWeight: 'bold',
height: 65,
flex: 1,
marginTop: -20,
paddingBottom: 0,
marginBottom: 0,
marginLeft:10,
textAlignVertical: 'center'
},
currencyTextStyle: {
fontSize: 50,
color: '#c0c0c0',
marginTop: -20,
textAlignVertical: 'center'
},
separatorStyle: {
height: 2,
marginTop: 0,
backgroundColor: '#c0c0c0',
},
categorySectionStyle: {
justifyContent: 'flex-start',
flexDirection: 'row',
alignItems: 'flex-start',
marginTop: 8
},
categoryColorDotStyle: {
width: 20,
height: 20,
borderRadius: 100/2,
marginLeft: 10,
marginTop: 5,
},
categoryTextStyle: {
fontSize: 24,
marginHorizontal: 4,
color: '#c0c0c0',
marginLeft: 10,
paddingRight: 10,
marginTop: -3
},
popupStyle: {
width: Dimensions.get('window').width - 60,
flexDirection: 'row',
justifyContent: 'space-between',
height: 150,
paddingRight:10,
paddingLeft:10,
borderRadius: 2,
margin: 20,
padding: 10,
opacity: 1,
borderRadius: 10,
backgroundColor: '#ffffff'
},
dropdownSeparator: {
height: 1,
backgroundColor: 'cornflowerblue'
},
这是托管组件:
render() {
var totalIncome = this.props.balance.totalIncome;
var totalExpanses = this.props.balance.totalExpanses;
return (
<View style={{flex:1, justifyContent: 'space-between'}}>
<Image pointerEvents='none' source={require('../../res/background.png')} style={styles.container} />
<MainScreenHeader onSettingPress={this._onBalanceSettingsPress.bind(this)}/>
<MainBalanceCounter totalCount={totalIncome} currentCount={totalIncome-totalExpanses} />
<View style={{justifyContent: 'center', alignItems: 'center', marginBottom: 150}}>
<AddPaymentButton onPress={this._onAddPaymentPress.bind(this)} />
<PaymentPopup
open={this.state.paymentPopupOpen}
onAddPaymentClicked={this._onPaymentPopupAddClicked.bind(this)} />
</View>
</View>
);
}
const styles = StyleSheet.create({
container: {
position: 'absolute',
top: 0,
left: 0,
right: 0,
bottom: 0,
width: undefined,
height: undefined,
backgroundColor:'transparent',
justifyContent: 'center',
alignItems: 'center',
},
innerContainer: {
justifyContent: 'space-around',
alignItems: 'center',
flex: 1,
backgroundColor: 'transparent'
},
});
我正在尝试使用一个可以捕获弹出窗口外发生的点击的视图,但没有成功。
非常感谢任何帮助,
谢谢, Giora。

你试过react-native-modalbox
吗?我在我的应用程序中使用它,它的工作非常好。如果您在模态后面有触摸事件,它将关闭。此外,您可以定义您希望模态的大小。它不必占用整个屏幕。
否则,你走在正确的轨道上。您需要一个涵盖屏幕整个宽度和高度的TouchableWithoutFeedback
组件。您的弹出窗口将与此组件一起使用更高的zIndex。如果你想走这条路,请告诉我,我可以提供更多建议。干杯!
