var Dimensions = require ('Dimensions') ;   //首先引入,然后使用即可
export default class Rule extends Component {
    constructor(props) {
        super(props);
        this.state = {
            
        };
    }
    render() {
		return (
			<View style={styles.container}>
                <View style={styles.title}>
                    <Text style={styles.titleText}>屏幕的宽是：{Dimensions.get('window').width}</Text>
                     <Text style={styles.titleText}>屏幕的高是：{Dimensions.get('window').height}</Text>
                      <Text style={styles.titleText}>屏幕的设备分辨率是：{Dimensions.get('window').scale}</Text>
                </View>
		);
    }
}
const styles = StyleSheet.create({
    container: {
        flex: 1,
        backgroundColor: 'white',
        justifyContent: 'flex-start',
        alignItems: 'flex-start',
    },
	divideLine: {
	    height:0.5,
	    width: Dimensions.get('window').width - 20,
	    borderWidth: 0.5,
	    borderColor: '#cccccc',
