javascript - react native 渐变按钮

Question

我的 btn 组件有问题，我正在使用 react-native-linear-gradient 库...

btn.js

import React,{ Component } from 'react';
import {View,Text,StyleSheet, TouchableOpacity} from 'react-native';
import {Button,Item} from 'native-base';

import LinearGradient from 'react-native-linear-gradient';

class GradientBtn extends Component {
    constructor(props){
        super(props);
    }
    render(){
    return(     
        <LinearGradient colors={['#d7d7d7', '#fafafa', '#e8e8e8']} 
        style={[styles.btnContainer,{height:this.props.h,width:this.props.w}]}>
            <Text style={styles.btn}>{this.props.name}</Text>
        </LinearGradient>





    );
  }
}

var styles = StyleSheet.create({
    btnContainer:{
        backgroundColor:'#f0f0f0',
        justifyContent:'center',
        marginLeft:1
    },
    btn:{
        textAlign:'center',
        color:'#000',
        fontWeight:'700',
        fontSize:12
    }
});

export default GradientBtn;

app.js

<View style={{flexDirection:'row',justifyContent:'space-between',marginTop:5}}>
    <TouchableOpacity>
        <GradientBtn h={35} w={'24.55%'} name="Open Corrective"/>
    </TouchableOpacity>
    <TouchableOpacity>
        <GradientBtn h={35} w={'24.55%'} name="Open Corrective"/>
    </TouchableOpacity>
    <TouchableOpacity>
        <GradientBtn h={35} w={'24.55%'} name="Open Corrective"/>
    </TouchableOpacity>
    <TouchableOpacity>
        <GradientBtn h={35} w={'24.55%'} name="Open Corrective"/>
    </TouchableOpacity>
</View>

当我从组件中删除 TouchableOpacity 标签时， View 会正常，但是当我放置此标签时，我想在该 btn 上触摸不透明度，然后我的 View 将压缩意味着宽度并且没有看到正确的 btn..

使用https://www.npmjs.com/package/react-native-linear-gradient

<LinearGradient colors={['#FF00FF', '#FFF000', '#FF0000']}
    style={{borderRadius: 20, width: width/3}} 
    start={{ y: 0.0, x: 0.0 }} end={{ y: 0.0, x: 1.0 }}>

    <Button style={{borderRadius: 20, width: width/3, 
        textAlign: 'center', color: '#fff'}} title={`Welcome`}/>

</LinearGradient>

或

<LinearGradient colors={['#4c669f', '#3b5998', '#192f6a']} 
    style={styles.linearGradient} 
    start={{ y: 0.0, x: 0.0 }} end={{ y: 0.0, x: 1.0 }}>
        <Text style={styles.buttonText}> Done </Text>
 </LinearGradient>

const styles = StyleSheet.create({

  linearGradient: {
    flex: 1,
    paddingLeft: 15
    paddingRight: 15,
    borderRadius: 5
  },
  buttonText: {
    fontSize: 18,
    fontFamily: 'Gill Sans',
    textAlign: 'center',
    margin: 10,
    color: '#ffffff',
    backgroundColor: 'transparent',
  },

});
