這裏是我的主要組成部分的簡化exctracts沒有更新:反應本地列表視圖時,行與它自己的狀態的組件
// this is only to simulate a change
componentDidMount() {
setTimeout(() => {
this.setState({
dataSource: this.state.dataSource.cloneWithRows([ newVehicle ]),
})
}, 5000)
}
render() {
return (
<ListView
dataSource={this.state.dataSource}
renderRow={this.renderVehicle}
/>
)
}
renderVehicle(vehicle) {
// here vehicle.name is properly updated
return <Text>{vehicle.name}</Text> // this would be working
return <Vehicle parentObject={ vehicle } /> // this is not working
}
這裏是我的車輛部件:
// In here it seams the component is not rebuilt,
// and this.props.parentObject is always the old value...
this.state = this.props.parentObject
return() {
<Text>{this.state.name}</Text>
}
注意:現實生活中的車輛是一個複雜的組件,需要擁有自己的狀態。
這就是它!謝謝 – alexandre
