这是我的解决方案键盘解散和滚动到点击TextInput(我使用的是ScrollView与keyboardDismissMode道具):

import React from 'react';
import {
  Platform,
  KeyboardAvoidingView,
  ScrollView
} from 'react-native';

const DismissKeyboard = ({ children }) => {
  const isAndroid = Platform.OS === 'android';
  const behavior = isAndroid ? false : 'padding';

  return (
    <KeyboardAvoidingView
      enabled
      behavior={ behavior }
      style={{ flex: 1}}
    >
      <ScrollView
        keyboardShouldPersistTaps={'always'}
        keyboardDismissMode={'on-drag'}
      >
        { children }
      </ScrollView>
    </KeyboardAvoidingView>
  );
};

export default DismissKeyboard;

用法:

render(){
   return(
     <DismissKeyboard>
       <TextInput
        style={{height: 40, borderColor: 'gray', borderWidth: 1}}
        onChangeText={(text) => this.setState({text})}
        value={this.state.text}
      />
     </DismissKeyboard>
   );
}

键盘模块用于控制键盘事件。

import {Keyboard} from 'react-native' 在渲染方法中添加以下代码。 呈现(){ 返回<TextInput onSubmitEditing={键盘。驳回}/ >; ｝

你可以使用-

Keyboard.dismiss()

解散活动键盘，并根据react本机文档删除焦点。

如果有人需要一个工作的例子，如何解散一个多行文本输入在这里ya !希望这能帮助一些人，文档没有描述一种方法来消除多行输入，至少没有具体的参考如何做到这一点。仍然是一个在堆栈上实际发帖的新手，如果有人认为这应该是对这个片段所写的实际帖子的引用，请告诉我。

import React, { Component } from 'react'
import {
  Keyboard,
  TextInput,
  TouchableOpacity,
  View,
  KeyboardAvoidingView,
} from 'react-native'

class App extends Component {
  constructor(props) {
    super(props)
    this.state = {
      behavior: 'position',
    }
    this._keyboardDismiss = this._keyboardDismiss.bind(this)
  }

  componentWillMount() {
    this.keyboardDidHideListener = Keyboard.addListener('keyboardDidHide', this._keyboardDidHide);
  }

  componentWillUnmount() {
    this.keyboardDidHideListener.remove()
  }

  _keyboardDidHide() {
    Keyboard.dismiss()
  }

  render() {
    return (
      <KeyboardAvoidingView
        style={{ flex: 1 }}
        behavior={this.state.behavior}
      >
        <TouchableOpacity onPress={this._keyboardDidHide}>
          <View>
            <TextInput
              style={{
                color: '#000000',
                paddingLeft: 15,
                paddingTop: 10,
                fontSize: 18,
              }}
              multiline={true}
              textStyle={{ fontSize: '20', fontFamily: 'Montserrat-Medium' }}
              placeholder="Share your Success..."
              value={this.state.text}
              underlineColorAndroid="transparent"
              returnKeyType={'default'}
            />
          </View>
        </TouchableOpacity>
      </KeyboardAvoidingView>
    )
  }
}

使用ScrollView而不是View，并将keyboardShouldPersistTaps属性设置为false。

<ScrollView style={styles.container} keyboardShouldPersistTaps={false}>
    <TextInput
        placeholder="Post Title"
        onChange={(event) => this.updateTitle(event.nativeEvent.text)}
        style={styles.default}/>
 </ScrollView>

将TextInput的父组件View包装到一个可压组件中，然后传递Keyboard。解散到onPress道具。因此，如果用户点击TextInput字段之外的任何地方，它将触发键盘。导致TextInput字段失去焦点，键盘被隐藏。

<Pressable onPress={Keyboard.dismiss}>
  <View>
    <TextInput
      multiline={true}
      onChangeText={onChangeText}
      value={text}
      placeholder={...}
     />
   </View>
</Pressable>

我们可以在没有react-native反馈的情况下使用keyboard和tochable

const DismissKeyboard = ({ children }) => (
  <TouchableWithoutFeedback
    onPress={() => Keyboard.dismiss()}
  >
    {children}
  </TouchableWithoutFeedback>
);

并这样使用它:

const App = () => (
  <DismissKeyboard>
    <View style={styles.container}>
      <TextInput
        style={styles.input}
        placeholder="username"
        keyboardType="numeric"
      />
      <TextInput
        style={styles.input}
        placeholder="password"
      />
    </View>
  </DismissKeyboard>
);
