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}
/>

我想分享我的解决方案使用功能组件…“这个”不需要!

React 16.12.0和React Native 0.61.5

这是我的组件的一个例子:

import React, { useRef } from 'react'
...


const MyFormComponent = () => {

  const ref_input2 = useRef();
  const ref_input3 = useRef();

  return (
    <>
      <TextInput
        placeholder="Input1"
        autoFocus={true}
        returnKeyType="next"
        onSubmitEditing={() => ref_input2.current.focus()}
      />
      <TextInput
        placeholder="Input2"
        returnKeyType="next"
        onSubmitEditing={() => ref_input3.current.focus()}
        ref={ref_input2}
      />
      <TextInput
        placeholder="Input3"
        ref={ref_input3}
      />
    </>
  )
}

我就是这样做到的。下面的例子使用了React 16.3中引入的React. createref () API。

class Test extends React.Component {
  constructor(props) {
    super(props);
    this.secondTextInputRef = React.createRef();
  }

  render() {
    return(
        <View>
            <TextInput
                placeholder = "FirstTextInput"
                returnKeyType="next"
                onSubmitEditing={() => { this.secondTextInputRef.current.focus(); }}
            />
            <TextInput
                ref={this.secondTextInputRef}
                placeholder = "secondTextInput"
            />
        </View>
    );
  }
}

我想这对你有帮助。

<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();
}

此处为具有:focus属性的输入组件的试剂溶液。

只要这个道具设置为true，字段就会被聚焦;如果这个道具设置为false，字段就不会有焦点。

不幸的是，这个组件需要定义一个:ref，我找不到其他方法来调用.focus()。我很高兴听到建议。

(defn focusable-input [init-attrs]
  (r/create-class
    {:display-name "focusable-input"
     :component-will-receive-props
       (fn [this new-argv]
         (let [ref-c (aget this "refs" (:ref init-attrs))
               focus (:focus (ru/extract-props new-argv))
               is-focused (.isFocused ref-c)]
           (if focus
             (when-not is-focused (.focus ref-c))
             (when is-focused (.blur ref-c)))))
     :reagent-render
       (fn [attrs]
         (let [init-focus (:focus init-attrs)
               auto-focus (or (:auto-focus attrs) init-focus)
               attrs (assoc attrs :auto-focus auto-focus)]
           [input attrs]))}))
