React native Can'；在文本框外单击时，不能模糊显示输入

我有一个简短的表单，它有两个FormInput字段（来自react原生元素）。当触摸屏幕上文本输入之外的任何地方时，我尝试了几种方法来消除焦点（并隐藏键盘）

  <View style={{flex:1}}>
  <ScrollView keyboardShouldPersistTaps="handled">
    <FormInput
        placeholder='Phone Number'
        errorStyle={{ color: 'red' }}
        inputStyle={{ color: 'white', fontSize: 20, fontFamily: 'Roboto-Thin', borderBottomColor: 'transparent'}}
        placeholderTextColor='white'
        onChangeText = {this.onPhoneChange.bind(this)}
        containerStyle = {{ borderBottomWidth: 1, borderBottomColor: '#4DB1AD', width: '90%'}}
        keyboardType='numeric'
        maxLength={10}
    />
    </ScrollView>
    </View>

我也试过了

  <TouchableWithoutFeedback style={{flex: 1}} onPress={Keyboard.dismiss} accessible={false}>
  <View>
    <FormInput
        placeholder='Phone Number'
        errorStyle={{ color: 'red' }}
        inputStyle={{ color: 'white', fontSize: 20, fontFamily: 'Roboto-Thin', borderBottomColor: 'transparent'}}
        placeholderTextColor='white'
        onChangeText = {this.onPhoneChange.bind(this)}
        containerStyle = {{ borderBottomWidth: 1, borderBottomColor: '#4DB1AD', width: '90%'}}
        keyboardType='numeric'
        maxLength={10}
        onSubmitEditing={Keyboard.dismiss}
        onBlur={Keyboard.dismiss}
        blurOnSubmit={true}
    />
    </View>
    </TouchableWithoutFeedback>

这个方法呢

  <TouchableOpacity activeOpacity={1} onPress={() => Keyboard.dismiss()}>
    <FormInput
        placeholder='Phone Number'
        errorStyle={{ color: 'red' }}
        inputStyle={{ color: 'white', fontSize: 20, fontFamily: 'Roboto-Thin', borderBottomColor: 'transparent'}}
        placeholderTextColor='white'
        onChangeText = {this.onPhoneChange.bind(this)}
        containerStyle = {{ borderBottomWidth: 1, borderBottomColor: '#4DB1AD', width: '90%'}}
        keyboardType='numeric'
        maxLength={10}
    />
    </TouchableOpacity>

Keyboard.disclose（）}>

不幸的是，这些解决方案都不适合我
