Question

我想处理平面列表索引。我想将平面列表索引转换为messageID

我的主要请求，我想更改平面清单项目数据

我有这样的json数组；

 this.state.messages = [
      {
        "date": "09:55",
        "longDate": "22/10/2018",
        "message": "ghjghj",
        "messageID": 157,
        "senderID": 1,
        "showLongDate": 0,
        "type": "text",
        "uri": ""
      },
      {
        "date": "09:56",
        "longDate": "22/10/2018",
        "message": "rtyrtyrt",
        "messageID": 158,
        "senderID": 1,
        "showLongDate": 0,
        "type": "text",
        "uri": ""
      }
    ]

我的单位列表；

 <FlatList
  ref={(list) => this.myFlatList = list}           
  data={this.state.messages}
  renderItem={({item, index})=>(
    <View><Text>{item.message}</Text></View> 
  )}
  removeClippedSubviews={true} 
  refreshing={this.state.refreshing} 
  keyExtractor={(item, index) => item.messageID.toString()} 
  onRefresh={this.handleRefresh}  
  extraData={this.state}   
/>
