我學習react-native，我跑來到這個疑難問題有一個類listView.js其中包含ListView，我想展現給在index.android.js 我得到的錯誤是陣營本地導入一個類來顯示的ListView不工作

我index.android.js是
import React, {Component} from 'react';
import {Text, View, AppRegistry, StyleSheet, TextInput,Switch} from 'react-native';
import listView from './app/otherClass/listView';
export default class first_app extends Component{
constructor(){
super();
this.state={
textValue:'Hello Mithun',
switchValue:false
}
}
switch_switch(value){
this.setState({
switchValue:value
});
}
onTextChange(value){
this.setState({
textValue:value
});
}
render(){
return(
<View>
<TextInput
placeholder="Enter some text"
value={this.state.textValue}
onChangeText={(value)=>this.onTextChange(value)}
/>
<Text>{this.state.textValue}</Text>
<Switch
value={this.state.switchValue}
onValueChange={(value)=> this.switch_switch(value)}
/>
<View>
<Text>{listView}</Text>
</View>
</View>
);
}
}
const style=StyleSheet.create({
myView: {
backgroundColor:'#00f'
},
myText: {
color: '#fff'
}
});
AppRegistry.registerComponent('first_app',()=>first_app);
而且我listView.js是
import React, {Component} from 'react';
import {Text, View, AppRegistry, StyleSheet, TextInput,ListView} from 'react-native';
const users=[
{name:'Chiranjibi poudel'},
{name:'Rishi ram mukhiya'},
{name:'Mahendra Bhat'},
{name:'Surya Man Shrestha'}
]
export default class listView extends Component{
constructor(){
super();
const ds = new ListView.DataSource({rowHasChanged: (r1, r2) => r1 !== r2});
this.state={
userData: ds.cloneWithRows(users),
};
}
renderRow(users,sectionId,rowId,highlightRow){
return(
<View>
<Text>{users.name}</Text>
</View>
);
}
render(){
return(
<ListView
dataSource:{this.state.userData}
renderRow={(users) => <Text>{users}</Text>}
/>
);
}
}
AppRegistry.registerComponent('listView',()=>listView);
通往listView.js的路徑是絕對正確的。 我不知道我在哪裏錯了。 謝謝。
