FlatList onClick导航到下一个屏幕 [英] FlatList onClick navigate to next screen

问题描述

在react-native中在Flatlist中单击一行时，如何使Flatlist导航到下一个屏幕?

How do I make a Flatlist navigate to the next screen when a row is clicked inside the Flatlist in react-native?

已编辑:我将所有代码发布到了JS文件中.

Edited: I posted all the codes inside my JS file.

这是我的固定列表代码:

Here is my flatlist code:

import React, { Component } from 'react';
import {
    StyleSheet,
    Text,
    View,
    FlatList,
    Button,
    TouchableOpacity,
    TouchableHighlight
} from 'react-native'

const Tasks = (props) => {
     const { navigate } = props.navigation;
     return (
      <View style={styles.container}>
        <FlatList
          data={[
            {key: 'Task 1'},
            {key: 'Task 2'},
            {key: 'Task 3'},
            {key: 'Task 4'},
            {key: 'Task 5'},
          ]}
          renderItem={({item}) => <TouchableHighlight onPress={() => this.goToNextScreen()}>
      <Text style={styles.item}>{item.key}</Text>}
</TouchableHighlight>}
        />
          <TouchableOpacity style={{ height: 50, marginTop: 5, marginLeft: 100, marginRight: 100 }}>
         <Button
              onPress={()=>navigate('Steps')}
              title="Steps"
              />  
              </TouchableOpacity>
      </View>
    );
  }


const styles = StyleSheet.create({
  container: {
   flex: 1,
   paddingTop: 22
  },
  item: {
    padding: 10,
    fontSize: 18,
    height: 44,
  },
})

Tasks.navigationOptions = {
    title: 'Task Order',
};

export default Tasks

推荐答案

我有一个简单的示例:

//Tasks Component
const Tasks = (props) => {
     const { navigate } = props.navigation;
     //function to go to next screen
     goToNextScreen = () => {
         return navigate('Detail');
     }
     return (
      <View>
        <FlatList
          data={[
            {key: 'Task 1'},
            {key: 'Task 2'},
            {key: 'Task 3'},
            {key: 'Task 4'},
            {key: 'Task 5'},
          ]}
          renderItem={({item}) => {
              return(
                <TouchableHighlight onPress={() => this.goToNextScreen()}>
                     <Text >{item.key}</Text>
                </TouchableHighlight>
              )
            }
          }
        />
      </View>
    );
}

//example for detail screen
const Detail = (props) => {
    const { navigate } = props.navigation;
    return(
        <View><Text>Detail Screen</Text></View>
    );
}

//initial screen
const App = StackNavigator({
  Tasks: {screen: Tasks},
  Detail: {screen: Detail},
})
