如何对React Native中的flatlist项目执行点击函数

Question

我正在获取数据列表，当单击平面列表的任何项目是我的代码时，我想显示每个数据的详细信息。

 <FlatList style={{paddingBottom:5}}
          data = {this.state.fetchFreelancer}
          keyExtractor={(y, z) => z.toString()}
          renderItem={({ item }) =>
          <FreelancerCategory
          imageUrifreelancer = {{uri: `${item.profile_img}`}}
          imageUrifeatured = {{uri: `${item.badge.badget_url}`}}
          featuredColor ={`${entities.decode(item.badge.badget_color)}`}
          flagimageUri= {{uri: `${item.location.flag}`}}
          freelancername={`${entities.decode(item.name)}`}
          title={`${entities.decode(item._tag_line)}`}
          rate={`${entities.decode(item._perhour_rate)}`}
          country={`${entities.decode(item.location._country)}`}
          /> 

但是我无法在平面列表中执行任何onpress，请为此提供帮助。谢谢

它不起作用..

<FlatList
                style={{ paddingBottom: 5 }}
                data={this.state.fetchFreelancer}
                keyExtractor={(y, z) => z.toString()}
                renderItem={({ item }) => (
                  <TouchableOpacity
                 onPress={() => navigate('DetailFreelancerScreen', {profile_id: item.profile_id})}
                //  onPress={() => alert('Item pressed')}
                  >
                    <FreelancerCategory
                      imageUrifreelancer={{ uri: `${item.profile_img}` }}
                      imageUrifeatured={{ uri: `${item.badge.badget_url}` }}
                      featuredColor={`${entities.decode(
                        item.badge.badget_color
                      )}`}
                      flagimageUri={{ uri: `${item.location.flag}` }}
                      freelancername={`${entities.decode(item.name)}`}
                      title={`${entities.decode(item._tag_line)}`}
                      rate={`${entities.decode(item._perhour_rate)}`}
                      country={`${entities.decode(item.location._country)}`}
                    />
                  </TouchableOpacity>
                )}
              />

如果要执行单击事件，则应用touchableOpacity或touchable withableWithOutFeedback覆盖您的项目。

<FlatList 
    style={{paddingBottom:5}}
    data = {this.state.fetchFreelancer}
    keyExtractor={(y, z) => z.toString()}
    renderItem={({ item }) => (
        <TouchableOpacity
           onPress={() => this.props.navigation.navigate('DetailFreelancerScreen', 
               {profile_id: item.profile_id})}
        >
           <FreelancerCategory
             imageUrifreelancer = {{uri: `${item.profile_img}`}}
             imageUrifeatured = {{uri: `${item.badge.badget_url}`}}
             featuredColor ={`${entities.decode(item.badge.badget_color)}`}
             flagimageUri= {{uri: `${item.location.flag}`}}
             freelancername={`${entities.decode(item.name)}`}
             title={`${entities.decode(item._tag_line)}`}
             rate={`${entities.decode(item._perhour_rate)}`}
             country={`${entities.decode(item.location._country)}`}
          /> 
       </TouchableOpacity>
      );
  />
