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>
        )
    }
})

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>
   );
}

在ScrollView中使用

keyboardShouldPersistTaps="handled" 

这个可以帮到你。

首次导入键盘

import { Keyboard } from 'react-native'

然后在你的TextInput你添加键盘。解散到onSubmitEditing道具。你应该有这样的东西:

render(){
  return(
    <View>
      <TextInput 
        onSubmitEditing={Keyboard.dismiss}
       />
    </View>
  )  
}

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!

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>
