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>

有几种方法， 如果你像onPress一样控制事件，你可以使用:

import { Keyboard } from 'react-native'

onClickFunction = () => {
     Keyboard.dismiss()
}

如果你想关闭键盘时使用滚动:

<ScrollView keyboardDismissMode={'on-drag'}>
     //content
</ScrollView>

更多的选项是当用户点击键盘外:

<KeyboardAvoidingView behavior='padding' style={{ flex: 1}}>
    //inputs and other content
</KeyboardAvoidingView>

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>
   );
}

Keyboard.dismiss()就会这样做。但有时它可能会失去焦点，键盘将无法找到ref。最一致的方法是将ref=_ref放到textInput中，当你需要解除时执行_ref.blur()，当你需要恢复键盘时执行_ref.focus()。

onStartShouldSetResponder道具停止触摸事件传播到TouchableWithoutFeedback元素。

<TouchableWithoutFeedback onPress={...}>
  <View>
    <ScrollView>
      <View onStartShouldSetResponder={() => true}>
        // Scrollable content
      </View>
    </ScrollView>
  </View>
</TouchableWithoutFeedback>

使用ScrollView代替带有keyboardShouldPersistTaps={"always"}属性的View。当我们点击屏幕内的任何地方时，它会隐藏键盘

<ScrollView keyboardShouldPersistTaps={"always"}>
 <View style={styles.container}>
  <Text style={styles.welcome}>
    Welcome to React Native!
  </Text>
  <Text style={styles.instructions}>
    To get started, edit index.ios.js
  </Text>
  <Text style={styles.instructions}>
    Press Cmd+R to reload,{'\n'}
    Cmd+D or shake for dev menu
  </Text>
  <TextInput
    style={{height: 40, borderColor: 'gray', borderWidth: 1}}
    onEndEditing={this.clearFocus}
  />
 </View>
</ScrollView>
