反应原生：ListView不呈现一行

Question

我正在使用redux来获取列表数据。我一直在加载列表数据。 <Text>no Data</Text>消失。但是，ListView不显示任何行。 我

这是我的代码（删除日志代码）：

import React, {PropTypes,Component} from 'react'; 
import { 
    AppRegistry, 
    StyleSheet, 
    Text, 
    View, 
    ListView, 
    Image, 
    Dimensions, 
} from 'react-native'; 

import {bindActionCreators} from 'redux'; 
import { fetchDocotorList } from '../../actions/findActions' 
import { connect } from 'react-redux'; 
const {width} = Dimensions.get('window'); 
const ds = new ListView.DataSource({rowHasChanged: (r1, r2) => r1 !== r2}); 
class DoctorList extends Component { 

    constructor(props) { 
    super(props); 
    this.state = { 
     dataSource: ds.cloneWithRows([]), 
     loaded: false, 
    }; 
    } 

    componentDidMount(){ 
    this.props.fetchDocotorList(); 
    } 

    componentWillReceiveProps(nextProps){ 
    if(nextProps.loaded){ 
     this.setState({ 
     dataSouce:this.state.dataSource.cloneWithRows(nextProps.doctorList), 
     loaded: nextProps.loaded, 
     }) 
    } 
    } 

    render() { 
    const { doctorList } = this.props; 
    const { loaded } = this.state; 
    if(!loaded){ 
     return (
      <View> 
      <Text>no Data</Text> 
      </View> 
      ) 
    }else{ 
     return (
       <View style={styles.container}> 
      <View style={styles.listViewBox}> 
       <ListView style={{flex: 1}} enableEmptySections={true} 
         dataSource={this.state.dataSource} renderRow={ 
       (rowData, sectionID, rowID, highlightRow) => { 
        return (
          <Text>{rowID}</Text> 
        ); 
       } 
       }/> 
      </View> 
      </View> 
     ); 
    } 
    }

DoctorList.defaultProps = {

DoctorList.propTypes = { 
    doctorList:PropTypes.array, 
    loaded:PropTypes.bool,

    return { 
    doctorList: state.find.doctorList, 
    loaded :state.find. fetched, 
    }; 
}; 

const mapDispatchToProps = dispatch => (
    bindActionCreators({ 
     fetchDocotorList, 
    }, dispatch) 
); 

export default connect(mapStateToProps, mapDispatchToProps)(DoctorList);

看起来你有一个错字。你想：

dataSource={this.state.dataSource}

但你设置dataSouce的状态来代替。 （请注意，没有r）
