如何在本机反应中关闭模态? [英] How to close modal in react native?

问题描述

当用户点击添加评论按钮时，我有添加评论按钮，他应该能够添加和保存评论.对于评论保存，我使用了 Modal.现在我想在用户点击 Modal 外部时关闭 Modal 我该怎么做这是 React Native?

I have add comment button when user clicks on add comment button he should be able to add and save comment. For comment save I have used Modal. Now I want to close Modal when user clicks outside Modal how can I do this is React Native ?

我指的是这个 -> 关闭本机反应通过单击叠加层来设置模态? 但该解决方案在我的情况下不起作用.

I am referring this -> Close react native modal by clicking on overlay? but the solution is not working in my case.

注意:我添加了关闭模态的按钮，但我想通过在模态外部单击来关闭它.

Note: I have added button to close modal but I want to close the modal by clicking outside it.

代码:

    <View>
            <Modal
            animationType="slide"
            transparent={true}
            visible={this.state.modalVisible}
            onRequestClose={() => {this.setModalVisible(false)}}>
            <TouchableOpacity  
            activeOpacity={1} 
            onPressOut={() => {this.setModalVisible(true)}}
            >
            <ScrollView 
            directionalLockEnabled={true} 
            contentContainerStyle={styles.scrollModal}
            >
            <TouchableWithoutFeedback>
            <View style={styles.commentModal}>
                <View style={{marginLeft: 20, marginRight: 20}}>
                    <Text style={styles.addCommentModal}>Add a Comment</Text>
                <View style={styles.textInputModal}>
                    <TextInput 
                        editable = {true}
                        maxLength = {40}
                        multiline = {true}
                        onChangeText={(text) => this.setState({text})}
                        value={this.state.comment_text}
                        onChangeText={(text) => this.setState({comment_text: text})}
                        style={{borderRadius: 1}}
                    />
                </View>
                <View style={styles.modalBtnContainer}>
                    <TouchableOpacity onPress={() => this.addComment(this.state.comment_text, logged_in_user.id, marketingPlanId)}>
                        <Text style={styles.saveCommentModal}>Save Comment</Text>
                    </TouchableOpacity>
                </View>
                <View style={styles.modalBtnContainer}>
                    <TouchableOpacity onPress={() => this.setModalVisible(false)}>
                        <Text style={styles.closeCommentModal}>Close</Text>
                    </TouchableOpacity>
                </View>
                </View>
            </View>
            </TouchableWithoutFeedback> 
            </ScrollView>
            </TouchableOpacity> 
            </Modal>
        </View>

CSS:

 commentModal: {
        position: 'absolute', 
        bottom: 0, 
        backgroundColor: '#fff', 
        height: height/2, 
        width: width
    },
    addCommentModal: {
        fontSize: 18, 
        color: '#333', 
        marginTop: 20, 
        fontFamily: 'bold', 
        fontWeight: '500' 
    },

推荐答案

请注意，在您发布的链接中，他们将 onPressOut 用于 <TouchableOpacity/> 组件而你正在使用 onPress，他也在一开始就使用了这个 if (!this.state.modalVisible) return null

notice that in the link you posted they are using onPressOut for <TouchableOpacity/> component and you are using onPress, he is also using this at the very beginning if (!this.state.modalVisible) return null
