Question

我的问题是我的刷卡器不显示图像。有刷卡器和刷卡器中的点，但未显示图像。我对本机很陌生。这是我的代码：

import React from 'react';
import { 
    StyleSheet, 
    View,
    Image,
    Text
} from 'react-native';
import Swiper from 'react-native-swiper';

export default class HomeScreen extends React.Component {
  state = {
    data: []
  }
  componentDidMount = () => {
    this.setState({
      data: this.props.navigation.getParam('data', 'NO-DATA')
    });
  }
  render() {
    return (
      <View style={styles.container}>
        <Swiper
          style = {styles.swiper }
        >
        {
          this.state.data.map( (item, i) => {
          <View>
            <Text> {item.url} </Text>
            <Image
              style={{width: 200, height: 200}}
              source={{uri: item.url}}
            />
          </View>
          })
        }
        </Swiper>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: 'red',
    alignItems: 'center',
    justifyContent: 'center',
  },
  swiper: {
    width: 200,
    height: 200
  }
});

问题不仅与图像有关，还与文本等有关。我想念什么吗？

在地图内缺少返回项，请添加它。

 nvcc -I/my/include/path/1 -I/usr/local/cuda/include src/myfile.cu -o build/myfile.o -arch=sm_61 -c --compiler-options -fPIC -Xcudafe -std=c++11

或者不退货。如果使用（此括号，则无需添加return
