Answer 1

The React Native Button is very limited in what you can do, see; Button

It does not have a style prop, and you don't set text the "web-way" like <Button>txt</Button> but via the title property <Button title="txt" />

If you want to have more control over the appearance you should use one of the TouchableXXXX' components like TouchableOpacity They are really easy to use :-)

Answer 2

I had an issue with margin and padding with a Button. I added Button inside a View component and apply your properties to the View.

<View style={{margin:10}}>
<Button
  title="Decrypt Data"
  color="orange"
  accessibilityLabel="Tap to Decrypt Data"
  onPress={() => {
    Alert.alert('You tapped the Decrypt button!');
  }}
  />  
</View>

Answer 3

If you do not want to create your own button component, a quick and dirty solution is to wrap the button in a view, which allows you to at least apply layout styling.

For example this would create a row of buttons:

<View style={{flexDirection: 'row'}}>
    <View style={{flex:1 , marginRight:10}} >
        <Button title="Save" onPress={() => {}}></Button>
    </View>
    <View style={{flex:1}} >
        <Button title="Cancel" onPress={() => {}}></Button>
    </View>
</View>

React Native buttons are very limited in the option they provide.You can use TouchableHighlight or TouchableOpacity by styling these element and wrapping your buttons with it like this

             <TouchableHighlight 
                style ={{
                    height: 40,
                    width:160,
                    borderRadius:10,
                    backgroundColor : "yellow",
                    marginLeft :50,
                    marginRight:50,
                    marginTop :20
                }}>
            <Button onPress={this._onPressButton}            
            title="SAVE"
            accessibilityLabel="Learn more about this button"
          /> 
          </TouchableHighlight> 

You can also use react library for customised button .One nice library is react-native-button (https://www.npmjs.com/package/react-native-button)

Answer 5

Only learning myself, but wrapping in a View may allow you to add styles around the button.

const Stack = StackNavigator({
  Home: {
    screen: HomeView,
    navigationOptions: {
      title: 'Home View'
    }
  },
  CoolView: {
    screen: CoolView,
    navigationOptions: ({navigation}) => ({
      title: 'Cool View',
      headerRight: (<View style={{marginRight: 16}}><Button
        title="Cool"
        onPress={() => alert('cool')}
      /></View>
    )
    })
  }
})

Answer 6

Instead of using button . you can use Text in react native and then make in touchable

<TouchableOpacity onPress={this._onPressButton}> 
   <Text style = {'your custome style'}>
       button name
   </Text>
</TouchableOpacity >

Answer 7

Try This one

<TouchableOpacity onPress={() => this._onPressAppoimentButton()} style={styles.Btn}>
    <Button title="Order Online" style={styles.Btn} > </Button>
</TouchableOpacity>

Answer 8

We can use buttonStyle prop now.
