设置第二个TextInput焦点，当前一个TextInput的onSubmitEditing被触发时。

试试这个

为第二个TextInput添加一个引用 Ref ={(input) => {this。secondTextInput =输入;}} 绑定焦点函数到第一个TextInput的onSubmitEditing事件。 onSubmitEditing={() => {this.secondTextInput.focus();}} 记住将blurOnSubmit设置为false，以防止键盘闪烁。 blurOnSubmit ={假}

当一切都完成后，它应该看起来像这样。

<TextInput
    placeholder="FirstTextInput"
    returnKeyType="next"
    onSubmitEditing={() => { this.secondTextInput.focus(); }}
    blurOnSubmit={false}
/>

<TextInput
    ref={(input) => { this.secondTextInput = input; }}
    placeholder="secondTextInput"
/>

在React Native的GitHub问题上尝试这个解决方案。

你需要为TextInput组件使用ref道具。 然后你需要创建一个函数，该函数在onSubmitEditing道具上被调用，将焦点移动到第二个TextInput引用上。

var InputScreen = React.createClass({
    _focusNextField(nextField) {
        this.refs[nextField].focus()
    },

    render: function() {
        return (
            <View style={styles.container}>
                <TextInput
                    ref='1'
                    style={styles.input}
                    placeholder='Normal'
                    returnKeyType='next'
                    blurOnSubmit={false}
                    onSubmitEditing={() => this._focusNextField('2')}
                />
                <TextInput
                    ref='2'
                    style={styles.input}
                    keyboardType='email-address'
                    placeholder='Email Address'
                    returnKeyType='next'
                    blurOnSubmit={false}
                    onSubmitEditing={() => this._focusNextField('3')}
                />
                <TextInput
                    ref='3'
                    style={styles.input}
                    keyboardType='url'
                    placeholder='URL'
                    returnKeyType='next'
                    blurOnSubmit={false}
                    onSubmitEditing={() => this._focusNextField('4')}
                />
                <TextInput
                    ref='4'
                    style={styles.input}
                    keyboardType='numeric'
                    placeholder='Numeric'
                    blurOnSubmit={false}
                    onSubmitEditing={() => this._focusNextField('5')}
                />
                <TextInput
                    ref='5'
                    style={styles.input}
                    keyboardType='numbers-and-punctuation'
                    placeholder='Numbers & Punctuation'
                    returnKeyType='done'
                />
            </View>
        );
    }
});

使用回调引用而不是遗留的字符串引用:

<TextInput
    style = {styles.titleInput}
    returnKeyType = {"next"}
    autoFocus = {true}
    placeholder = "Title"
    onSubmitEditing={() => {this.nextInput.focus()}}
/>
<TextInput
    style = {styles.descriptionInput}  
    multiline = {true}
    maxLength = {200}
    placeholder = "Description"
    ref={nextInput => this.nextInput = nextInput}
/>

<TextInput 
    keyboardType="email-address"
    placeholder="Email"
    returnKeyType="next"
    ref="email"
    onSubmitEditing={() => this.focusTextInput(this.refs.password)}
    blurOnSubmit={false}
 />
<TextInput
    ref="password"
    placeholder="Password" 
    secureTextEntry={true} />

并添加方法onSubmitEditing={() => this.focusTextInput(this.ref .password)}如下所示:

private focusTextInput(node: any) {
    node.focus();
}

使用react-native 0.45.1我还遇到了问题，试图在按下用户名TextInput的返回键后将焦点设置在密码TextInput上。

在尝试了这里的大多数顶级解决方案之后，我在github上找到了一个解决方案，满足了我的需求: https://github.com/shoutem/ui/issues/44#issuecomment-290724642

总结一下:

import React, { Component } from 'react';
import { TextInput as RNTextInput } from 'react-native';

export default class TextInput extends Component {
    render() {
        const { props } = this;

        return (
            <RNTextInput
                {...props}
                ref={(input) => props.inputRef && props.inputRef(input)}
            />
        );
    }
}

然后我这样使用它:

import React, {Component} from 'react';
import {
    View,
} from 'react-native';
import TextInput from "../../components/TextInput";

class Login extends Component {
    constructor(props) {
        super(props);
        this.passTextInput = null
    }

    render() {
        return (
            <View style={{flex:1}}>
                <TextInput
                    style={{flex:1}}
                    placeholder="Username"
                    onSubmitEditing={(event) => {
                        this.passTextInput.focus()
                    }}
                />

                <TextInput
                    style={{flex:1}}
                    placeholder="Password"
                    inputRef={(input) => {
                        this.passTextInput = input
                    }}
                />
            </View>
        )
    }
}

import React, { useState, useEffect, useRef, } from 'react';

const OTP = (props) => {



    const OTP = [];
    const ref_input = [];
    ref_input[0] = useRef();
    ref_input[1] = useRef();
    ref_input[2] = useRef();
    ref_input[3] = useRef();

    const focusNext = (text, index) => {
        if (index < ref_input.length - 1 && text) {
            ref_input[index + 1].current.focus();
        }
        if (index == ref_input.length - 1) {
            ref_input[index].current.blur();
        }
        OTP[index] = text;
    }
    const focusPrev = (key, index) => {
        if (key === "Backspace" && index !== 0) {
            ref_input[index - 1].current.focus();
        }
    }
