React-Native-特定页面上的Backbutton处理程序

Question

我想使用react native在特定页面上禁用android后退按钮处理程序

Answer 1

禁用Android设备后退按钮

它将处理Back Press，

import { BackHandler } from 'react-native';

    constructor(props) {
        super(props)
    }

    componentWillMount() {
        BackHandler.addEventListener('hardwareBackPress', this.handleBackButtonClick);
    }

    componentWillUnmount() {
        BackHandler.removeEventListener('hardwareBackPress', this.handleBackButtonClick);
    }

    handleBackButtonClick = () => {
        this.props.navigation.goBack(null);
        return true;
    };
