反应导航不改变屏幕

我试图通过单击平面列表中的元素导航到另一个屏幕(艺术家)。此平面列表包含艺术家实例,如\u renderListItem方法中设置的。到目前为止我已经试过了 不同的方法(目前有两种方法被注释掉),但似乎都不起作用:

方法1:导航操作

方法3:Navigator.push

    console.log(typeId)
    console.log(typeName)
    console.log(imageUrl)

     this.props.navigation.navigate('HomeStack',{},

艺术家.js

_onPress() 方法似乎正在工作(此处预期的参数值正确),但我无法导航到此屏幕。

import React, { Component } from 'react';
import { createStackNavigator } from 'react-navigation';
import {
  ScrollView,
  StyleSheet,
  View,
  Text,
  TouchableOpacity,
  Image,
} from 'react-native';

class Artist extends React.PureComponent {

  _onPress = () => {
     // console.log(this.props)

     const itemId = this.props.itemId
     const itemName = this.props.itemName
     const itemImageUrl = this.props.itemImageUrl

    console.log(itemId)
    console.log(itemName)
    console.log(itemImageUrl)

// FOR PUSH
  //   this.props.onPressItem(
  //     this.props.itemid,
  //     this.props.itemName,
  //     this.props.itemImageUrl,
  //   );
  // };
}

  static navigationOptions = {
    title: 'Artist',
  };

  render() {
    return (
      <TouchableOpacity
        {...this.props}
        style={styles.grid}
        onPress={this._onPress}>
        <Image
          style={styles.image}
          source={{uri: this.props.itemImageUrl}}
        />
        <Text style={styles.title}>{this.props.itemName}</Text>
      </TouchableOpacity>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    backgroundColor: '#000000',
  },
  grid: {
    marginTop: 15,
    marginBottom: 15,

    width: 115,
    borderBottomWidth: 1,
    borderBottomColor: '#191970',
  },
  title: {
    color: '#FFFFFF',
    textAlign: 'left',
    fontSize: 12,
  },
  image: {

export default Artist;
