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>
);

我还在这里用源代码进行了解释。

import {Keyboard} from 'react-native';

使用keyboard .dismiss()隐藏你的键盘在任何onClick或onPress事件。

如果你有keyboardType='numeric'，键盘不解散的问题会变得更严重，因为没有办法解散它。

用ScrollView替换View不是一个正确的解决方案，因为如果你有多个textinput或按钮，在键盘打开时点击它们只会让键盘消失。

正确的方法是用TouchableWithoutFeedback封装视图并调用Keyboard.dismiss()

编辑:你现在可以使用带有keyboardShouldPersistTaps='handled'的ScrollView来只在点击没有被孩子处理的时候解散键盘。点击其他文本，输入或按钮)

如果你有

<View style={{flex: 1}}>
    <TextInput keyboardType='numeric'/>
</View>

改为

<ScrollView contentContainerStyle={{flexGrow: 1}}
  keyboardShouldPersistTaps='handled'
>
  <TextInput keyboardType='numeric'/>
</ScrollView>

or

import {Keyboard} from 'react-native'

<TouchableWithoutFeedback onPress={Keyboard.dismiss} accessible={false}>
    <View style={{flex: 1}}>
        <TextInput keyboardType='numeric'/>
    </View>
</TouchableWithoutFeedback>

编辑:你也可以创建一个高阶组件来取消键盘。

import React from 'react';
import { TouchableWithoutFeedback, Keyboard, View } from 'react-native';

const DismissKeyboardHOC = (Comp) => {
  return ({ children, ...props }) => (
    <TouchableWithoutFeedback onPress={Keyboard.dismiss} accessible={false}>
      <Comp {...props}>
        {children}
      </Comp>
    </TouchableWithoutFeedback>
  );
};
const DismissKeyboardView = DismissKeyboardHOC(View)

就像这样简单地使用它

...
render() {
    <DismissKeyboardView>
        <TextInput keyboardType='numeric'/>
    </DismissKeyboardView>
}

注意:需要accessible={false}使输入表单可以通过VoiceOver继续访问。视障人士会感谢你的!

将此用于自定义撤销

var dismissKeyboard = require('dismissKeyboard');

var TestView = React.createClass({
    render: function(){
        return (
            <TouchableWithoutFeedback 
                onPress={dismissKeyboard}>
                <View />
            </TouchableWithoutFeedback>
        )
    }
})

使用keyboard .dismiss()在任何时候解散键盘。

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'}
            />
