ButtonGroup

ButtonGroup is a linear set of segments, each of which function as a button that can display a different view. Use a ButtonGroup to offer choices that are closely related but mutually exclusive.

Usage

Using strings

constructor () {  super()  this.state = {    selectedIndex: 2  }  this.updateIndex = this.updateIndex.bind(this)}
updateIndex (selectedIndex) {  this.setState({selectedIndex})}
render () {  const buttons = ['Hello', 'World', 'Buttons']  const { selectedIndex } = this.state
  return (    <ButtonGroup      onPress={this.updateIndex}      selectedIndex={selectedIndex}      buttons={buttons}      containerStyle={{height: 100}}    />  )}

Using components

constructor () {  super()  this.state = {    selectedIndex: 2  }  this.updateIndex = this.updateIndex.bind(this)}updateIndex (selectedIndex) {  this.setState({selectedIndex})}
const component1 = () => <Text>Hello</Text>const component2 = () => <Text>World</Text>const component3 = () => <Text>ButtonGroup</Text>
render () {  const buttons = [{ element: component1 }, { element: component2 }, { element: component3 }]  const { selectedIndex } = this.state  return (    <ButtonGroup      onPress={this.updateIndex}      selectedIndex={selectedIndex}      buttons={buttons}      containerStyle={{height: 100}} />  )}
