How to change background color of react native button

Question

I am trying to change the background color of my button but nothing seems to work, I tried the raised property, maybe i am using it incorrectly. Do any of you have any ideas?

 import React from 'react';
 import { StyleSheet, Text, View, Button, TouchableHighlight } from 'react-native';

export default class App extends React.Component {
state={
  name: "Mamadou"
};

myPress = () => {
  this.setState({
    name: "Coulibaly"
  });
};

  render() {
    return (
      <View style={styles.container}>

          <Button       
          title={this.state.name}
          color="red"
          onPress={this.myPress}
        />   

      </View>

    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#fff',
    alignItems: 'center',
    justifyContent: 'center',
  },

});

Solution 1

Use this for adding the background color to the button in iOS:

Styles:

  loginScreenButton:{
    marginRight:40,
    marginLeft:40,
   marginTop:10,
    paddingTop:10,
    paddingBottom:10,
    backgroundColor:'#1E6738',
    borderRadius:10,
    borderWidth: 1,
    borderColor: '#fff'
  },
  loginText:{
      color:'#fff',
      textAlign:'center',
      paddingLeft : 10,
      paddingRight : 10
  }

Button:

<TouchableOpacity
          style={styles.loginScreenButton}
          onPress={() => navigate('HomeScreen')}
          underlayColor='#fff'>
          <Text style={styles.loginText}>Login</Text>
 </TouchableOpacity>

For Android it simply works with Button color property only:

<Button  onPress={onPressAction}  title="Login"  color="#1E6738"  accessibilityLabel="Learn more about this button" />

Solution 2

I suggest to use React Native Elements package, which allow to insert styles throught buttonStyle property.

styles:

const styles = StyleSheet.create({
   container: {
      flex: 1
   },
   button: {
      backgroundColor: '#00aeef',
      borderColor: 'red',
      borderWidth: 5,
      borderRadius: 15       
   }
})

render()

render() {
   return (
      <View style={styles.container}>
          <Button
             buttonStyle={styles.button}
             title="Example"
             onPress={() => {}}/>
      </View>
   )
}

"color" property applies to background only if you're building for android.

Other than that I personally find it easier to manage custom buttons. That is create your own component named button and have it as a view with text. This way its way more manageable and you can import it as easy as Button.
