我有一個包含 12 項的串列，但我想給出串列中每個月的名稱，而不是“串列項#$index”標題。我怎樣才能做到這一點？
這是我的代碼和照片：
ListView _buildListView(BuildContext context){
List months =
['January', 'February', 'March', 'April', 'May','June','July','August','September','October','November','December'];
int i=0;
return ListView.builder(itemCount: 12,
itemBuilder: (_, index){
return ListTile(
title: Text('the list item#$index'),
subtitle: Text('thesubtitle'),
leading: Icon(Icons.account_balance_wallet_rounded),
trailing: Icon(Icons.arrow_forward),
onTap: (){
Navigator.push(
context,
MaterialPageRoute(builder: (context) => DetailPage(index))
);
},
);
},
);
}
這是詳細資訊頁面代碼：
class DetailPage extends StatelessWidget{
final int index;
DetailPage(this.index);
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text('detailsPage'),
),
body: Center(
child: Text('The details page#$index',style: TextStyle(fontSize: 32.0),),
),
);
}
}

使用itemCount而不是像硬編碼的值
return ListView.builder(
itemCount: months.length,
itemBuilder: (_, index) {
final month = months[index];
return ListTile(
title: Text('the list ${month}'),
uj5u.com熱心網友回復：
用這個
months[index]
滿的：
ListView _buildListView(BuildContext context){
List<String> months =
['January', 'February', 'March', 'April', 'May','June','July','August','September','October','November','December'];
int i=0;
return ListView.builder(itemCount: 12,
itemBuilder: (_, index){
return ListTile(
title: Text(months[index]),
subtitle: Text('thesubtitle'),
leading: Icon(Icons.account_balance_wallet_rounded),
trailing: Icon(Icons.arrow_forward),
onTap: (){
Navigator.push(
context,
MaterialPageRoute(builder: (context) => DetailPage(index))
);
},
);
},
);
}
