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" />
...

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

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();
}
