如果你需要组件保持加载但隐藏，你可以将不透明度设置为0。(例如，我需要这个世博会相机)

//in constructor    
this.state = {opacity: 100}

/in component
style = {{opacity: this.state.opacity}}

//when you want to hide
this.setState({opacity: 0})

实际上，在iOS开发中，通过react-native，当我使用display: 'none'或如下所示:

const styles = StyleSheet.create({
  disappearImage: {
    width: 0,
    height: 0
  }
});

iOS不加载任何其他的图像组件，如onLoad或等，所以我决定使用如下:

const styles = StyleSheet.create({
  disappearImage: {
    width: 1,
    height: 1,
    position: 'absolute',
    top: -9000,
    opacity: 0
  }
});

隐藏并显示活动指示器的父视图

constructor(props) {
  super(props)

  this.state = {
    isHidden: false
  }  
} 

像跟着一样隐藏和显示

{
   this.state.isHidden ?  <View style={style.activityContainer} hide={false}><ActivityIndicator size="small" color="#00ff00" animating={true}/></View> : null
}

全部参考

render() {
    return (
       <View style={style.mainViewStyle}>
          <View style={style.signinStyle}>
           <TextField placeholder='First Name' keyboardType='default' onChangeFirstName={(text) => this.setState({firstName: text.text})}/>
           <TextField placeholder='Last Name' keyboardType='default' onChangeFirstName={(text) => this.setState({lastName: text.text})}/>
           <TextField placeholder='Email' keyboardType='email-address' onChangeFirstName={(text) => this.setState({email: text.text})}/>
           <TextField placeholder='Phone Number' keyboardType='phone-pad' onChangeFirstName={(text) => this.setState({phone: text.text})}/>
           <TextField placeholder='Password' secureTextEntry={true} keyboardType='default' onChangeFirstName={(text) => this.setState({password: text.text})}/>
           <Button  style={AppStyleSheet.buttonStyle} title='Sign up' onPress={() => this.onSignupPress()} color='red' backgroundColor='black'/>
          </View>
          {
            this.state.isHidden ?  <View style={style.activityContainer}><ActivityIndicator size="small" color="#00ff00" animating={true}/></View> : null
          }
      </View>
   );
}

在按钮上按下设置状态如下所示

onSignupPress() {
  this.setState({isHidden: true})
}

当你需要躲藏的时候

this.setState({isHidden: false})

checkincheckout = () => {
        this.setState({ visible: !this.state.visible })
}

render() {
        return (
{this.state.visible == false ?
        <View style={{ alignItems: 'center', flexDirection: 'row', marginTop: 50 }}>

        <View style={{ flex: 1, alignItems: 'center', flexDirection: 'column' }}>

            <TouchableOpacity onPress={() => this.checkincheckout()}>

                <Text style={{ color: 'white' }}>Click to Check in</Text>

            </TouchableOpacity>

        </View>

    </View>
:
<View style={{ alignItems: 'center', flexDirection: 'row', marginTop: 50 }}>

<View style={{ flex: 1, alignItems: 'center', flexDirection: 'column' }}>

   <TouchableOpacity onPress={() => this.checkincheckout()}>

        <Text style={{ color: 'white' }}>Click to Check out</Text>

    </TouchableOpacity>

</View>

</View>
 }

);
}

这一切。享受你的编码……

我也有同样的问题，我想要显示/隐藏视图，但我真的不希望UI在添加/删除东西或必须处理重新渲染时跳来跳去。

我写了一个简单的组件来处理它。默认为动画，但易于切换。我把它放在GitHub和NPM上，但所有的代码都在下面。

NPM install——save react-native- hidden -view

import React, { Component, PropTypes } from 'react';
import { Animated  } from 'react-native';

class HideableView extends Component {
  constructor(props) {
    super(props);
    this.state = {
      opacity: new Animated.Value(this.props.visible ? 1 : 0)
    }
  }

  animate(show) {
    const duration = this.props.duration ? parseInt(this.props.duration) : 500;
    Animated.timing(
      this.state.opacity, {
        toValue: show ? 1 : 0,
        duration: !this.props.noAnimation ? duration : 0
      }
    ).start();
  }

  shouldComponentUpdate(nextProps) {
    return this.props.visible !== nextProps.visible;
  }

  componentWillUpdate(nextProps, nextState) {
    if (this.props.visible !== nextProps.visible) {
      this.animate(nextProps.visible);
    }
  }

  render() {
    if (this.props.removeWhenHidden) {
      return (this.visible && this.props.children);
    }
    return (
      <Animated.View style={{opacity: this.state.opacity}}>
        {this.props.children}
      </Animated.View>
    )
  }
}

HideableView.propTypes = {
  visible: PropTypes.bool.isRequired,
  duration: PropTypes.number,
  removeWhenHidden: PropTypes.bool,
  noAnimation: PropTypes.bool
}

export default HideableView;

非常容易。只需更改为()=> this.showCancel()，如下所示:

<TextInput
        onFocus={() => this.showCancel() }
        onChangeText={(text) => this.doSearch({input: text})} />

<TouchableHighlight 
    onPress={this.hideCancel()}>
    <View>
        <Text style={styles.cancelButtonText}>Cancel</Text>
    </View>
</TouchableHighlight>
