我的场景是< CustomBoladonesTextInput />包装一个RN < TextInput />。

我是这样解决这个问题的:

我的表单是这样的:

  <CustomBoladonesTextInput 
      onSubmitEditing={() => this.customInput2.refs.innerTextInput2.focus()}
      returnKeyType="next"
      ... />

  <CustomBoladonesTextInput 
       ref={ref => this.customInput2 = ref}
       refInner="innerTextInput2"
       ... />

在CustomBoladonesTextInput的组件定义中，我像这样将refField传递给内部的ref道具:

   export default class CustomBoladonesTextInput extends React.Component {
      render() {        
         return (< TextInput ref={this.props.refInner} ... />);     
      } 
   }

瞧。一切恢复正常。 希望这能有所帮助

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}
/>

结合@Eli Johnson的功能组件解决方案和@Rodrigo Tessarollo的CustomTextInput解决方案:

import React, { useRef } from 'react';
import { CustomTextInput } from 'path/to/CustomTextInput';
...


export const MyFormComponent = () => {

  const ref_to_input2 = useRef();

  return (
    <>
      <CustomTextInput
        placeholder="Input 1"
        autoFocus={true}
        returnKeyType="next"
        onSubmitEditing={() => ref_to_input2.current.focus()}
      />
      <CustomTextInput
        placeholder="Input 2"
        returnKeyType="done"
        refInner={ref_to_input2}
        onSubmitEditing={/* Do something! */}
      />
    </>
  )
}

在你的CustomTextInput组件中:

import { TextInput } from "react-native";
export const CustomTextInput = (props) => {
  <TextInput
        ref={props.refInner}
        {...props}
  />
}

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 placeholder="Nombre"
    ref="1"
    editable={true}
    returnKeyType="next"
    underlineColorAndroid={'#4DB6AC'}
    blurOnSubmit={false}
    value={this.state.First_Name}
    onChangeText={First_Name => this.setState({ First_Name })}
    onSubmitEditing={() => this.focusNextField('2')}
    placeholderTextColor="#797a7a" style={{ marginBottom: 10, color: '#808080', fontSize: 15, width: '100%', }} />

<TextInput placeholder="Apellido"
    ref="2"
    editable={true}
    returnKeyType="next"
    underlineColorAndroid={'#4DB6AC'}
    blurOnSubmit={false}
    value={this.state.Last_Name}
    onChangeText={Last_Name => this.setState({ Last_Name })}
    onSubmitEditing={() => this.focusNextField('3')}
    placeholderTextColor="#797a7a" style={{ marginBottom: 10, color: '#808080', fontSize: 15, width: '100%', }} />

和add方法

focusNextField(nextField) {
    this.refs[nextField].focus();
}

如果你的TextInput在另一个组件中，要让这个被接受的解决方案工作，你需要从ref“弹出”到父容器的引用。

// MyComponent
render() {
    <View>
        <TextInput ref={(r) => this.props.onRef(r)} { ...this.props }/>
    </View>
}

// MyView
render() {
    <MyComponent onSubmitEditing={(evt) => this.myField2.focus()}/>
    <MyComponent onRef={(r) => this.myField2 = r}/>
}
