我的抽屉导航是一个堆栈导航,这意味着我创建一个自定义抽屉作为堆栈导航,如下所示:
class DrawerComponent extends React.Component {
navigateToScreen = (route) => (
() => {
const navigateAction = NavigationActions.navigate({
routeName: route
});
this.props.navigation.dispatch(navigateAction);
});
render() {
return (
<ScrollView style={Styles.containerDrawer}>
<View style={Styles.logoContainer}>
<Image source={Images.logo}
style={Styles.imageStyle}
resizeMode={'contain'}
/>
</View>
<View style={Styles.blocksContainer}>
<View style={Styles.firstBlock}>
<TouchableOpacity
style={[Styles.buttonMenue, Styles.elevationButton, Styles.bgButton, Styles.centerContent]}
onPress= {this.navigateToScreen('Messages')}
>
<IconMCI
name="message-text-outline" size={wp('10%')} color= '#000'
style={Styles.iconStyle}
/>
<Text style={Styles.textButton}>الرسائل</Text>
</TouchableOpacity>
<TouchableOpacity
style={[Styles.buttonMenue, Styles.elevationButton, Styles.bgButton, Styles.centerContent]}
onPress= {this.navigateToScreen('Home')}
>
<IconSI
name="home" size={wp('10%')} color= '#000'
style={Styles.iconStyle}
/>
<Text style={Styles.textButton}>الإستقبال</Text>
</TouchableOpacity>
</View>
我的问题是我无法改变所选项目的风格。
您可以使用状态来处理项目的点击事件并根据它更改类别,下面提供了一个示例
class DrawerComponent extends React.Component {
state={
clicked:true;
}
navigateToScreen = (route) => (
() => {
const navigateAction = NavigationActions.navigate({
routeName: route
});
this.props.navigation.dispatch(navigateAction);
});
render() {
return (
...
<View style={Styles.blocksContainer}>
<View style={Styles.firstBlock}>
<TouchableOpacity
style={!this.state.clicked?[Styles.buttonMenue, Styles.elevationButton, Styles.bgButton, Styles.centerContent]:['custom-style']}
onPress= {()=>{
this.setState({clicked:true})
this.navigateToScreen('Messages')
}}
>
...
</TouchableOpacity>
</View>
这是更多的信息:
import React, {Component} from 'react';
import { createStackNavigator, createDrawerNavigator, createAppContainer } from 'react-navigation';
import HomeStackNavigation from './HomeStackNavigation'
import Messages from '../Components/Messages/Messages';
import DrawerComponent from '../Components/Drawer/Drawer';
import {Platform, Dimensions} from 'react-native';
// import ScoreList from '../Components/ScoreList/ScoreList';
var width = Dimensions.get('window').width;
const DrawerNavigation = createDrawerNavigator({
Home: { // entree (route name) : on peut la nommer comme on veut mais on prefere lui donner le meme nom que notre screen qu'on va afficher
screen: HomeStackNavigation, // le screen qu'on va afficher IL DOIT ETRE UN STACK
},
},
{
drawerWidth: width*0.83,
contentComponent: props =>
{
return(<DrawerComponent {...props}/>)
},
drawerPosition: 'left',
},
);
export default createAppContainer(DrawerNavigation)
你的this.props.activeItemKey
方法中的render
将为你提供当前的项目密钥,如Messages
,或Home
在你的情况下...你可以用来相应地设置活动项目的样式。
第二
如果可能的话,将您的StackNavigator在routeConfigs中呈现的屏幕移动到您的Drawer:
const DrawerNavigation = createDrawerNavigator({
Home: { screen: HomeScreen },
Screen2: { screen: StackScreen2 },
Screen3: { screen: StackScreen3 },
});
