【问题描述】：
我需要你的建议。 我有从 api 获取数据到 ListView 的代码。
问题是，如何在这个列表视图中创建搜索视图。
class PM extends StatefulWidget {
@override
_PMState createState() => _PMState();
}
class _PMState extends State<PM> {
final GlobalKey<ScaffoldState> _scaffoldKey = new GlobalKey<ScaffoldState>();
void showInSnackBar(String value) {
_scaffoldKey.currentState.showSnackBar(new SnackBar(
content: new Text(value),
backgroundColor: Colors.blueAccent,
));
}
final GlobalKey<RefreshIndicatorState> _refresh =
GlobalKey<RefreshIndicatorState>();
ModelPM modelPM;
ModelPM _modelPM;
bool loading = false;
Future<Null> _fetchData() async {
setState(() => loading = true);
var value;
SharedPreferences preferences = await SharedPreferences.getInstance();
setState(() {
value = preferences.getString("id");
});
final response = await http.post(BaseURL.systemTicket, body: {
"key": BaseURL.apiKey,
"method": "get",
"resource": "tabel_pm",
"filters[adminidtabelpm]": value,
});
if (response.statusCode == 200) {
final data = jsonDecode(response.body);
final pmModelFromJson = ModelPM.fromJson(data);
setState(() {
modelPM = pmModelFromJson;
loading = false;
});
} else {
showInSnackBar("Data Gagal Load");
}
}
@override
void initState() {
super.initState();
_fetchData();
}
_listPM(i) {
final x = modelPM.results[i];
return Card(
elevation: 8.0,
margin: new EdgeInsets.symmetric(horizontal: 10.0, vertical: 6.0),
child: ListTile(
onTap: () {
Navigator.of(context).push(
MaterialPageRoute(builder: (context) => DetilPM(x, _fetchData)));
},
contentPadding: EdgeInsets.symmetric(horizontal: 10.0, vertical: 5.0),
title: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text(
x.name,
textAlign: TextAlign.start,
style: TextStyle(
fontSize: 12,
color: x.status == "Not Yet"
? Colors.blue
: x.status == "Pending" ? Colors.red : Colors.green,
fontWeight: FontWeight.bold),
),
Text(
'Status : ' + x.status,
textAlign: TextAlign.start,
style: TextStyle(
fontSize: 12,
color: x.status == "Not Yet"
? Colors.blue
: x.status == "Pending" ? Colors.red : Colors.green,
fontWeight: FontWeight.bold),
),
SizedBox(
height: 10,
),
],
),
subtitle: Column(
children: <Widget>[
Row(
children: <Widget>[
Expanded(
flex: 4,
child: Padding(
padding: EdgeInsets.only(left: 0.0),
child: Text("MIDTID",
style: TextStyle(color: Colors.black, fontSize: 10))),
),
Expanded(
flex: 4,
child: Padding(
padding: EdgeInsets.only(left: 0.0),
child: Text("TID",
style: TextStyle(color: Colors.black, fontSize: 10))),
),
Expanded(
flex: 4,
child: Padding(
padding: EdgeInsets.only(left: 0.0),
child: Text("CSI",
style: TextStyle(color: Colors.black, fontSize: 10))),
),
],
),
Row(
children: <Widget>[
Expanded(
flex: 4,
child: Padding(
padding: EdgeInsets.only(left: 0.0),
child: Text(x.midtid,
style: TextStyle(color: Colors.black, fontSize: 10))),
),
Expanded(
flex: 4,
child: Padding(
padding: EdgeInsets.only(left: 0.0),
child: Text(x.tid,
style: TextStyle(color: Colors.black, fontSize: 10))),
),
Expanded(
flex: 4,
child: Padding(
padding: EdgeInsets.only(left: 0.0),
child: Text(x.csi,
style: TextStyle(color: Colors.black, fontSize: 10))),
),
],
)
],
),
trailing:
Icon(Icons.keyboard_arrow_right, color: Colors.black, size: 30.0),
),
);
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('PM CIMB List'),
),
key: _scaffoldKey,
body: RefreshIndicator(
onRefresh: _fetchData,
key: _refresh,
child: loading
? Center(child: CircularProgressIndicator())
: ListView.builder(
itemCount: modelPM.results.length,
itemBuilder: (context, i) {
return _listPM(i);
},
),
),
);
}
}
以及低于这个模型类的PM。
class ModelPM {
final int status;
final String status_message;
final List<ModelPMResult> results;
ModelPM({this.status, this.status_message, this.results});
factory ModelPM.fromJson(Map<String, dynamic> json) {
List<ModelPMResult> results = (json['result'] as List)
.map((resultTicketJson) => ModelPMResult.fromJson(resultTicketJson))
.toList();
return ModelPM(
status: json['status'],
status_message: json['status_message'],
results: results,
);
}
}
class ModelPMResult {
final String id;
final String admintabelpm;
final String namaitfs;
final String serial;
final String merchantid;
final String assetid;
final String kondisi_edc;
final String status;
final String detail_edc;
final String note;
final String foto_struk;
final String foto_mesin;
final String foto_toko;
final String kondisi_merchant;
final String request_merchant;
final String tgl_pm;
final String name;
final String batch;
final String idmerchant;
final String midtid;
final String tid;
final String csi;
final String sign;
ModelPMResult({
this.id,
this.admintabelpm,
this.namaitfs,
this.serial,
this.merchantid,
this.assetid,
this.kondisi_edc,
this.status,
this.detail_edc,
this.kondisi_merchant,
this.request_merchant,
this.tgl_pm,
this.name,
this.batch,
this.idmerchant,
this.midtid,
this.tid,
this.csi,
this.foto_mesin,
this.foto_struk,
this.foto_toko,
this.note,
this.sign,
});
factory ModelPMResult.fromJson(Map<String, dynamic> json) {
return new ModelPMResult(
id: json['id'],
admintabelpm: json['id'],
namaitfs: json['namaitfs'],
serial: json['serial'],
merchantid: json['merchantid'],
assetid: json['assetid'],
kondisi_edc: json['kondisi_edc'],
status: json['status'],
detail_edc: json['detail_edc'],
kondisi_merchant: json['kondisi_merchant'],
request_merchant: json['request_merchant'],
tgl_pm: json['tgl_pm'],
name: json['name'],
batch: json['batch'],
idmerchant: json['idmerchant'],
midtid: json['midtid'],
tid: json['tid'],
csi: json['csi'],
note: json['note'],
foto_mesin: json['foto_mesin'],
foto_toko: json['foto_toko'],
foto_struk: json['foto_struk'],
sign: json['sign'],
);
}
}
请咨询，如何在我的 Page Flutter 中创建列表视图菜单。 谢谢你的建议 。 以及在搜索菜单中删除数据后，API中的数据如何返回列表
