1.正向傳值以及配置callback
this.props.navigation.navigate('ChoosePersonActivity', {
data: '1', choosed: nowFuZePerson, callback: (backdata) => {
Alert.alert(backdata);
}
});
2.第二個頁面收到數(shù)據(jù)并返回數(shù)據(jù)
this.props.navigation.state.params.data
this.props.navigation.state.params.choosed
返回的方法：調(diào)用如下
this.props.navigation.state.params.callback('返回的數(shù)據(jù)');
this.props.navigation.goBack();
