交互提示方式dialog和snackbar
首先看看dialog的方式
new PopupMenuButton(
icon: new Icon(Icons.phone_iphone, color: Colors.blue,),
onSelected: (v){
showDialog<Null>(
context: context,
builder:(_){
return new AlertDialog(
content: new Text(v),
actions: <Widget>[
new FlatButton(
onPressed: () {
Navigator.of(_).pop();
},
child: new Text('确定')
)
]
);
}
);
}, itemBuilder: (BuildContext context) => <PopupMenuItem<String>>[
new PopupMenuItem<String>(
value: '选项一的值',
child: new Text('屏蔽这个问题')
),
new PopupMenuItem<String>(
value: '选项二的值',
child: new Text('取消关注')
),
new PopupMenuItem<String>(
value: '选项二的值',
child: new Text("举报")
)
] ),
snackbar
new PopupMenuButton(
icon: new Icon(Icons.phone_iphone, color: Colors.blue,),
//child: ImageIcon(AssetImage('images/wxzf.png'), size:20.0, color: Colors.blue,),
onSelected: (v){
final snackBar = new SnackBar(
content: new ListTile(leading: Icon(Icons.warning,color: Colors.red,),title: new Text(v),),
backgroundColor: Colors.blue,
duration: Duration(milliseconds: 2000),
); Scaffold.of(context).showSnackBar(snackBar);
}, itemBuilder: (BuildContext context) => <PopupMenuItem<String>>[
new PopupMenuItem<String>(
value: '选项一的值',
child: new Text('屏蔽这个问题')
),
new PopupMenuItem<String>(
value: '选项二的值',
child: new Text('取消关')
),
new PopupMenuItem<String>(
value: '选项二的值',
child: new Text("举报")
)
] ),
