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"
/>

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();
        }
    }

如果您恰好像我一样使用tcomb-form-native，您也可以这样做。这里有一个技巧:不是直接设置TextInput的道具，而是通过选项来实现。您可以将表单的字段引用为:

this.refs.form.getComponent('password').refs.input.focus()

所以最终的产品看起来是这样的:

var t = require('tcomb-form-native');
var Form = t.form.Form;

var MyForm = t.struct({
  field1:     t.String,
  field2:     t.String,
});

var MyComponent = React.createClass({

  _getFormOptions () {
    return {
      fields: {
        field1: {
          returnKeyType: 'next',
          onSubmitEditing: () => {this.refs.form.getComponent('field2').refs.input.focus()},
        },
      },
    };
  },

  render () {

    var formOptions = this._getFormOptions();

    return (
      <View style={styles.container}>
        <Form ref="form" type={MyForm} options={formOptions}/>
      </View>
    );
  },
});

从React Native 0.36开始，不再支持在文本输入节点上调用focus()(在其他几个答案中建议)。相反，你可以使用React Native中的TextInputState模块。我创建了以下帮助模块，使这更容易:

// TextInputManager
//
// Provides helper functions for managing the focus state of text
// inputs. This is a hack! You are supposed to be able to call
// "focus()" directly on TextInput nodes, but that doesn't seem
// to be working as of ReactNative 0.36
//
import { findNodeHandle } from 'react-native'
import TextInputState from 'react-native/lib/TextInputState'


export function focusTextInput(node) {
  try {
    TextInputState.focusTextInput(findNodeHandle(node))
  } catch(e) {
    console.log("Couldn't focus text input: ", e.message)
  }
}

然后，您可以在TextInput的任何“ref”上调用focusTextInput函数。例如:

...
<TextInput onSubmit={() => focusTextInput(this.refs.inputB)} />
<TextInput ref="inputB" />
...

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}
/>
