问题描述

我正在使用来自反应原生纸库的FAB( https://callstack.github.io/react-native-paper/fab.html#icon )。我想在底部对齐按钮,但它与 textInput 字段重叠,如何将它放在该 textInput 下方?请参阅下面的屏幕截图。

代码:

//Inside return
    <ScrollView>

                    <Text style={styles.title}>Add a Lead</Text>

                    <View style={styles.inputContainer}>
                        <Image source={require('../../assets/images/name.png')} style={{
                            marginTop: 15, width: 32, height: 32, resizeMode: 'contain'}}/>
                        <TextInput
                            placeholder='Name'
                            value={this.state.name}
                            style={styles.input}
                            onChangeText={ name => this.setState({name})}
                            error={this.state.nameError}
                        />
                    </View>
                    <HelperText type="error" visible={this.state.emailError}>
                        {this.state.emailError}
                    </HelperText>

            Similarly other items for phone email etc....

            <View style={{marginTop: 20, flex: 1, flexDirection: 'row'}}>
                        <Image source={require('../../assets/images/comment.png')} style={{
                            marginTop: 20, width: 32, height: 32, resizeMode: 'contain'}}/>
                        <Text style={{marginTop: 25, marginLeft: 15}}>Comment</Text>
                    </View> 

                    <View>
                        <TextInput
                            style={{height: 65, marginTop: 15, borderColor: 'gray', borderWidth: 1}}
                            onChangeText={(comment) => this.setState({comment})}
                            value={this.state.comment}
                            error={this.state.commentError}
                            multiline = {true}
                            numberOfLines = {4}
                        />
                    </View>
            <FAB
                    style={styles.fab}
                    small
                    icon="arrow_forward"
                    onPress={this.handleCreateNewLead}
                />
    </ScrollView>

CSS:

fab: {
        position: 'absolute',
        margin: 16,
        right: 0,
        bottom: -20,
    },

截屏:

解决方案


对于 textarea(您放置 ? 图标)添加位置:相对。

<TextInput style={{height: 65, marginTop: 15, borderColor: 'gray', borderWidth: 1, position: relative}}

并更改 fab 组件的以下样式

fab: {
        position: 'absolute',
        margin: 16,
        right: 10,
        bottom: 10,
    }

可能会奏效。
