import React, { PureComponent } from 'react';
import { View, StyleSheet, Dimensions, Platform } from 'react-native';
import PropTypes from 'prop-types';
import ECharts, { echarts } from 'react-native-echarts';
 
const { width, height } = Dimensions.get('window');
 
class ResponsiveEcharts extends PureComponent {
  constructor(props) {
    super(props);
    this.state = {
      height: 0,
      width: 0,
    };
    this.onLayout = this.onLayout.bind(this);
  }
 
  onLayout(event) {
    const { height, width } = event.nativeEvent.layout;
    if (this.state.height !== height || this.state.width !== width) {
      this.setState({ height, width });
    }
  }
 
  render() {
    const { option } = this.props;
    const { height: stateHeight, width: stateWidth } = this.state;
 
    const height = stateHeight || height;
    const width = stateWidth || width;
 
    return (
      <View style={styles.container} onLayout={this.onLayout}>
        <ECharts
          ref={(echarts) => { this.echarts = echarts; }}
          height={height}
          width={width}
          option={option}
          onChartReady={this.onChartReady}
          {...this.props}
        />
      </View>
    );
  }
}
 
ResponsiveEcharts.propTypes = {
  option: PropTypes.object.isRequired,
};
 
const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
});
 
export default ResponsiveEcharts;这段代码使用React Native和ECharts创建了一个名为ResponsiveEcharts的组件,该组件能够响应屏幕的宽度和高度变化。它使用了React的生命周期钩子和样式来确保图表能够适应不同的屏幕尺寸。这是一个很好的实践,可以作为创建响应式图表组件的参考。
