react-native-router-flux addListener 不起作用

Question

我正在使用

本机反应": "0.62.2", react-native-router-flux: "4.2.0-beta.1",

addListener 不起作用，并且 console.log 从不调用

    componentDidMount() {
        this.props.navigation.addListener(ActionConst.RESET, () => {
            console.log('RESET');
        });
        this.props.navigation.addListener(ActionConst.FOCUS, () => {
            console.log('FOCUS');
        });
        this.props.navigation.addListener(ActionConst.PUSH, () => {
            console.log('PUSH');
        });
        this.props.navigation.addListener(ActionConst.POP_TO, () => {
            console.log('POP_TO');
        });
}

有没有我可以查看的方法或文档？

Answer 1

你只有

willFocus - 屏幕将聚焦
didFocus - 屏幕聚焦（如果有转换，则转换完成）
willBlur - 屏幕将不聚焦
didBlur - 屏幕未聚焦（如果有过渡，则过渡完成）

添加监听器

componentDidMount(){
    const didBlurSubscription = this.props.navigation.addListener(
      'didBlur',() => {
         console.log('didBlur');
       }
    );
}

componentWillUnmount(){
    // Remove the listener when you are done
    didBlurSubscription.remove();
}
