我定义了两个TextInput字段如下:

<TextInput 
   style = {styles.titleInput}
   returnKeyType = {"next"}
   autoFocus = {true}
   placeholder = "Title" />
<TextInput
   style = {styles.descriptionInput}          
   multiline = {true}
   maxLength = {200}
   placeholder = "Description" />

但在按下键盘上的“next”按钮后,我的react-native应用程序并没有跳转到第二个TextInput字段。我怎样才能做到呢?

谢谢!


当前回答

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

其他回答

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"
/>

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react-native 0.45.1我还遇到了问题,试图在按下用户名TextInput的返回键后将焦点设置在密码TextInput上。

在尝试了这里的大多数顶级解决方案之后,我在github上找到了一个解决方案,满足了我的需求: https://github.com/shoutem/ui/issues/44#issuecomment-290724642

总结一下:

import React, { Component } from 'react';
import { TextInput as RNTextInput } from 'react-native';

export default class TextInput extends Component {
    render() {
        const { props } = this;

        return (
            <RNTextInput
                {...props}
                ref={(input) => props.inputRef && props.inputRef(input)}
            />
        );
    }
}

然后我这样使用它:

import React, {Component} from 'react';
import {
    View,
} from 'react-native';
import TextInput from "../../components/TextInput";

class Login extends Component {
    constructor(props) {
        super(props);
        this.passTextInput = null
    }

    render() {
        return (
            <View style={{flex:1}}>
                <TextInput
                    style={{flex:1}}
                    placeholder="Username"
                    onSubmitEditing={(event) => {
                        this.passTextInput.focus()
                    }}
                />

                <TextInput
                    style={{flex:1}}
                    placeholder="Password"
                    inputRef={(input) => {
                        this.passTextInput = input
                    }}
                />
            </View>
        )
    }
}

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。

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}
  />
}
