有一种方法可以捕获TextInput中的制表符。这很俗气，但总比没有好。

定义一个onChangeText处理程序，比较新输入值和旧输入值，检查是否有\t。如果找到一个，推进字段如@boredgames所示

假设变量username包含用户名的值，setUsername在存储(组件状态，redux存储等)中分派一个动作来更改它，执行如下操作:

function tabGuard (newValue, oldValue, callback, nextCallback) {
  if (newValue.indexOf('\t') >= 0 && oldValue.indexOf('\t') === -1) {
    callback(oldValue)
    nextCallback()
  } else {
    callback(newValue)
  }
}

class LoginScene {
  focusNextField = (nextField) => {
    this.refs[nextField].focus()
  }

  focusOnPassword = () => {
    this.focusNextField('password')
  }

  handleUsernameChange = (newValue) => {
    const { username } = this.props            // or from wherever
    const { setUsername } = this.props.actions // or from wherever

    tabGuard(newValue, username, setUsername, this.focusOnPassword)
  }

  render () {
    const { username } = this.props

    return (
      <TextInput ref='username'
                 placeholder='Username'
                 autoCapitalize='none'
                 autoCorrect={false}
                 autoFocus
                 keyboardType='email-address'
                 onChangeText={handleUsernameChange}
                 blurOnSubmit={false}
                 onSubmitEditing={focusOnPassword}
                 value={username} />
    )
  }
}

<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();
}

对于RN 0.50.3的我来说，这是可能的:

<TextInput 
  autoFocus={true} 
  onSubmitEditing={() => {this.PasswordInputRef._root.focus()}} 
/>

<TextInput ref={input => {this.PasswordInputRef = input}} />

你必须看到这个。

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}
/>

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"
/>

下面是如何为reactjs的电话代码输入实现这一点

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

function Header(props) {

  const [state , setState] = useState({
        phone_number:"",
        code_one:'',
        code_two:'',
        code_three:'',
        code_four:'',
        submitted:false,

  })

   const codeOneInput = useRef(null);
   const codeTwoInput = useRef(null);
   const codeThreeInput = useRef(null);
   const codeFourInput = useRef(null);

   const handleCodeChange = (e) => {
        const {id , value} = e.target
        if(value.length < 2){
            setState(prevState => ({
                ...prevState,
                [id] : value
            }))
            if(id=='code_one' && value.length >0){
                codeTwoInput.current.focus();
            }
            if(id=='code_two'  && value.length >0){
                codeThreeInput.current.focus();
            }
            if(id=='code_three'  && value.length >0){
                codeFourInput.current.focus();
            }
        }
    }

    const sendCodeToServer = () => {

         setState(prevState => ({
                ...prevState,
                submitted : true,
          }))
  let codeEnteredByUser = state.code_one + state.code_two + state.code_three + state.code_four

        axios.post(API_BASE_URL, {code:codeEnteredByUser})
        .then(function (response) {
            console.log(response)
        })

   }

   return(
        <>

           <div className="are">
                 <div className="POP-INN-INPUT">
                                        <input type="text" id="code_one" ref={codeOneInput}    value={state.code_one}  onChange={handleCodeChange} autoFocus/>
                                        <input type="text" id="code_two"  ref={codeTwoInput}  value={state.code_two} onChange={handleCodeChange}/>
                                        <input type="text" id="code_three"  ref={codeThreeInput} value={state.code_three}  onChange={handleCodeChange}/>
                                        <input type="text" id="code_four" ref={codeFourInput}  value={state.code_four}  onChange={handleCodeChange}/>
                                    </div>

            <button disabled={state.submitted} onClick={sendCodeToServer}>
   
    </div>

       </>
    )
