reactjs – React Native ListView性能太慢了吗?

前端之家收集整理的这篇文章主要介绍了reactjs – React Native ListView性能太慢了吗?前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我的application.react本机listView中有113条记录需要3秒多的时间来渲染所有行.我怎样才能使它高效,因此时间消耗可以最小化,应用体验可以顺利进行.我在ios中检查了相同的应用程序,与react-native app版本相比,它的效率非常高.我每行都有一个头像图像和名称和按钮.

这是我的listview代码

var Ziglist = React.createClass({
getInitialState: function() {
     return {
        isLoading: true,resultsData: new ListView.DataSource({
        rowHasChanged: (row1,row2) => row1 != row2 }),};
},componentWillMount: function(){
  PeopleStore.listen(this.onChange);
  PeopleActions.getPeopleFollowing();
},componentWillUnmount() {
  PeopleStore.unlisten(this.onChange);
},onChange(state) {
this.setState({resultsData: this.getDataSource(state.resultsData)})
},getDataSource: function(mediaItem: Array<any>): ListView.dataSource {
  return this.state.resultsData.cloneWithRows(mediaItem)
},render: function() {
    return (
  <View style={{flex: 1}} >
  <ListView
    dataSource={this.state.resultsData}
    renderRow={this.renderRow}
    renderSeperator={this.renderSeperator}
    contentInset={{top: 0}}
    automaticallyAdjustContentInsets={false}
  />
  <Button
    containerStyle={styles.goAhead}
    style={styles.base}
    onPress={() => this.onStartPress()}>
    <Text style={[styles.base,styles.go]}>Ok,Lets GO > </Text>
  </Button>
 </View>
);
},renderSeparator: function (sectionID: number | 
string,rowID: number | string,adjacentRowHighlighted: boolean ) {
 return (
    <View key={"SEP_" + sectionID + "_" + rowID} />
 );
},renderRow: function (
 media: Object,sectionID: number | string,highlightRowFunction: (sectionID: ?number | string,rowID: ?number | string) => void,) {
  return (
    <CelebrityRow
     media={media}
     onSelect={() => this.selectMediaItem(media)}
     onHighlight={() => highlightRowFunction(sectionID,rowID)}
     onDeHighlight={() => highlightRowFunction(null,null)}
    />
 );
},selectMediaItem: function (mediaItem) {
this.props.navigator.push({
  name: 'celebrityDetailView',passProps: {
    mediaItem: mediaItem
  }
});
}

这是Celebrity Row的代码

var CelebrityRow = React.createClass({
getInitialState: function() {
    return {
        following_ids: FollowingStore.getState().following_ids,unfollowing_ids: FollowingStore.getState().unfollowing_ids,icon: null,follow: true
    }
},componentWillMount: function() {
    if (_.indexOf(this.state.unfollowing_ids,this.props.media.id) > -1) {
        this.setState({
            follow: !this.state.follow
        });
    }
},componentWillUnmount: function() {},componentDidMount: function() {
    var _unfollowing_ids = FollowingStore.getState().unfollowing_ids;

    if (_unfollowing_ids.length > 0 && this.state.follow === false) {
        var following_arr = PeopleStore.getState().resultsData;
        var _following_ids = FollowingStore.getState().following_ids;

        _.each(_unfollowing_ids,function(id) {
            var find = _.findWhere(following_arr,{
                id: id
            });
            following_arr = _.without(following_arr,find);
        });

        var following_ids = _.difference(_following_ids,_unfollowing_ids);

        this.setState({
            unfollowing_ids: [],following_ids: following_ids
        });
        var _this = this;
        setTimeout(function() {
            FollowingActions.updateFollowingIdsWithStorage(following_ids);
            FollowingActions.updateUnFollowingIds([]);
            PeopleActions.updatePeopleFollowingWithStorage(following_arr);
            _this.setState({
                follow: true
            })
        },1000);

    }

},onChange: function(state) {
    // this.setState({unfollowing_ids: state.unfollowing_ids});
},onAddPress: function(media) {

    this.setState({
        follow: !this.state.follow
    });
    FollowingActions.updateUnFollowingIds(media.id);
},render: function() {

    return ( <
        View style = {
            styles.row
        } >
        <
        TouchableHighlight onPress = {

        }
        onHideUnderlay = {

        } >

        } >
        <
        Button onPress = {
            () => this.onAddPress(this.props.media)
        } > {
            (this.state.follow ?
                ( <
                    Image source = {
                        require("../assets/tick-mark.png")
