您好,我有一个Home
组件,其中有一个平面列表,其中显示应用程序的所有用户以及一些伪信息,他们的年龄等信息。当我们单击某个用户时,它将转到另一个组件UserProfil
,我们可以在其中获取有关用户的更多信息。我想实现一个刷卡器,让我在用户之间滑动。如何使用Home
中UserProfil
组件中的数据来启动刷卡器?
这是我的组件:
Home.js
class Accueil extends React.Component {
constructor(props) {
super(props);
this.state = {
loading: false,
refreshing: false,
location: null,
latitude:null,
longitude:null,
dataSource:[],
error:null
}
setInterval(this.displayPosition.bind(this),3000)
this.displayPosition = this.displayPosition.bind(this);
}
getData(){
fetch("someURL")
.then(res => res.json())
.then(res => {
this.setState({
dataSource: res
});
})
.catch(error => {
console.log("get data error:" + error);
}),
{
method: 'POST',
headers: {
Accept: 'application/json',
'Content-Type': 'application/json',
},
body: JSON.stringify({
lo: this.state.longitude,
la: this.state.latitude,
}),
}
}
_displayDetailForUser = (idUser, name, photo, age, pratique, description, distance, Statut, localisation, principale ) => {
//console.log("Display user with id " + idUser);
this.props.navigation.navigate("UserProfil", { MembreId: idUser, Pseudo:name, Photo: photo, Age:age, Genre:pratique, Description:description, Distance:distance, Statut:Statut, CP:localisation, Ville:principale });
}
render() {
return (
<SafeAreaView style={{ flex:1 }}>
<View style={styles.main_container}>
<FlatList style={styles.flatList}
data={this.state.dataSource}
extraData = {this.state}
keyExtractor={(item, index) => item.MembreId}
renderItem={(item) => <UserItem user={item} displayDetailForUser={this._displayDetailForUser} />}
numColumns={numColumns}
refreshing={this.state.refreshing}
onRefresh={this.handleRefresh} />
</View>
</SafeAreaView>
)
}
}
和 UserProfil
render () {
const { user } = this.props;
var colorConnected;
if (this.props.navigation.getParam('Statut') === "ON") {
colorConnected = "#1fbc26";
}
else if (this.props.navigation.getParam('Statut') === "OFF") {
colorConnected = "#ff0303";
}
else {
colorConnected = "#ffd200";
}
return (
<Swiper showsPagination={false}>
<ScrollView style = {styles.view_container}>
<View style={styles.photo}>
<ImageBackground source={{uri:this.props.navigation.getParam('Photo')}} style={{ width: '100%', height: '100%' }}>
<View style={styles.photo_content}>
<LinearGradient colors={['transparent', 'rgba(0,0,0,0.5)']} style={{ position: 'absolute', left: 0, right: 0, bottom: 0, height: 80 }} />
<View style={{ flexDirection: 'row', alignItems: 'center' }}>
<View>
<Text style={{ fontSize: 40, color:'white' }}>{this.props.navigation.getParam('Age')}</Text>
</View>
<View style={{ marginRight: 7, marginLeft: 7, backgroundColor: '#ffffff', width: 1, height: 39 }}></View>
<View style={{ flexDirection: 'column', flex:1 }}>
<View style={{ flexDirection: 'row' }}>
<View style={[styles.bulle_presence, { backgroundColor: colorConnected } ]}></View>
<Text style={{ fontSize: 18, fontWeight: '600', color:'white' }}>{this.props.navigation.getParam('Pseudo')}</Text>
</View>
<View style={{ flexDirection: 'row', justifyContent: 'space-between'}}>
<Text style={{ fontSize: 15, color:'white' }}>{this.props.navigation.getParam('Distance')}</Text>
<Text style={{ fontSize: 15, color:'white'}}>{this.props.navigation.getParam('Genre')}</Text>
</View>
</View>
</View>
</View>
</ImageBackgroud>
</View>
</ScrollView>
</Swiper>
)}
