I'm using react native to create a test App, There is no effect on a button when I do styling. can anyone tell me what I am doing wrong. For example, I am trying to put red color to a button but it is not working. What can I do to make it right?

import React, { Component } from 'react'

  AppRegistry,
  StyleSheet,

  Button,
  ScrollView,

import { StackNavigator } from 'react-navigation'





class Home extends Component{

  static navigationOptions = {

   title:'Home'



  };

ponentWillMount(){

  this.animatedValue = new Animated.ValueXY();
  this._value = {x:0 , y:0}
  this.animatedValue.addListener((value) => this._value = value);


this.panResponder = PanResponder.create({

 onStartShouldSetPanResponder: (evt, gestureState) => true,
  onMoveShouldSetPanResponder: (evt, gestureState) => true,
  onPanResponderGrant: (e, gestureState) => {

this.animatedValue.setOffset({

x:this._value.x,
y:this._value.y,

this.animatedValue.setValue({x:0 , y:0})

      },

• have you tried with inline style? – Jigar Shah Commented Jun 22, 2017 at 10:03
• Inline is working fine with the code. Issue is while importing it from external stylesheet. – Prabodh M Commented Jun 22, 2017 at 10:12
• well, other than that code looks okay, only button style is not working or all? – Jigar Shah Commented Jun 22, 2017 at 10:24
• yes, inline works :) – Vish_TS Commented Jun 22, 2017 at 11:18

You cannot apply color to a button using stylesheet.

Checkout the link here

It has to be given inline. It is a property of button, its not like style attribute unlike tags like View and Text, where stylesheet applies.

If you give some style to your view container it will work, but not with button as its it not supported that way.

Solution :

    <View style={styles.container}>
      <Button 
       title="Login"
       color="red"
       onPress={() => this.props.navigation.navigate("Login")} />
    </View>

Hope that helps!

If your button doesn't look right for your app, you can build your own button using TouchableOpacity or TouchableNativeFeedback. For inspiration, look at the source code for this button ponent. Or, take a look at the wide variety of button ponents built by the munity.

Look this:

 <TouchableOpacity
   style={[styles.buttonLargeContainer, styles.primaryButton]}
   onPress={() => {}}>
  <Text style={styles.buttonText}>SEND TO AUCTION?</Text>
 </TouchableOpacity>

const styles = StyleSheet.create({
buttonLargeContainer: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    marginRight: 10
  },
primaryButton: {
    backgroundColor: '#FF0017',
  },
buttonText: {
    color: 'white',
    fontSize: 14,
    fontWeight: 'bold'
  }
})
