React Native ListView列表多个数据源和状态机，取值，刷新状态机

constructor(props) {        super(props);        this.dataSource = Array(2).fill(            new ListView.DataSource({                /*判断这两行是否相同，就是是否发生变化，决定渲染哪些行组件，避免全部渲染，提高渲染效率*/                rowHasChanged: (oldRow, newRow) => {                    return oldRow !== newRow                }            })        );        this.state = {//状态机变量声明,            selectTab: 0,            listParams: Array(2).fill({                dataArray: [],                listState: CommonListView.STATE_INIT,                enableLoadMore: false,                pageNum: 1,            }),           searchParams: Array(2).fill({                searchText: '',                isHighlightFilter: false            }),        };    }

componentDidMount() {    this.setSearchParams({searchText: 'searchText', isHighlightFilter: true})    this.dataSource[this.state.selectTab] = this.dataSource[this.state.selectTab].cloneWithRows(newArray);}

 <ListView       dataSource={this.dataSource[this.state.selectTab]}></ListView>

setSearchParams(obj = {}, callBack) {        let newSearchParams = this.state.searchParams;        newSearchParams[this.state.selectTab] = Object.assign({}, newSearchParams[this.state.selectTab], obj);        this.setState({ // 重写setState, 刷新状态机            searchParams: newSearchParams        }, callBack && callBack())    }
