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。

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>
    );
  },
});

(感谢remcoanker在这里发布的想法:https://github.com/gcanti/tcomb-form-native/issues/96)

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"
/>

我创建了一个小库来做这件事，除了替换你的包装视图和导入TextInput，不需要更改代码:

import { Form, TextInput } from 'react-native-autofocus'

export default () => (
  <Form>
    <TextInput placeholder="test" />
    <TextInput placeholder="test 2" />
  </Form>
)

https://github.com/zackify/react-native-autofocus

详细解释在这里:https://zach.codes/autofocus-inputs-in-react-native/

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]))}))

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}
  />
}
