我面临的问题是，当我的ListView从视图中滚动时，仍然可以看到文本选择句柄。这里有一张照片供参考，它会解释得更好。https:/imgur.comaLg93cV9
我只在安卓系统上测试过，我没有iOS设备来测试。
这是我的主部件
@override
Widget body() {
return StoreConnector<AppState, Step1IntroViewModel>(
converter: (store) => Step1IntroViewModel.fromStore(store),
builder: (context, viewModel) {
return StepMainTemplate.build(
this.context,
child: Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.start,
children: <Widget>[
_buildImageWidget(),
Text(
'Upload image',
style: TextStyle(
color: Colors.red,
fontWeight: FontWeight.bold,
),
),
Expanded(
child: ListView(
children: <Widget>[
StepMainTemplate.title(
subtitle: 'Step 1 of 2',
title: 'Introduce yourself',
),
ProfileForm(
key: _profileFormKey,
initProfile: viewModel.profileState?.data,
),
Container(
padding: const EdgeInsets.fromLTRB(0, 40, 0, 20),
width: double.infinity,
child: RedOneButton.text(
text: "Next",
function: () {
var profile = _profileFormKey.currentState.save();
if (profile != null) {
viewModel.saveProfile(profile);
ExtendedNavigator.ofRouter<Router>()
.pushNamed(Routes.step2Route);
}
}),
),
],
),
),
],
),
);
},
);
}
这里是ProfileForm
class ProfileForm extends StatefulWidget {
final Profile initProfile;
const ProfileForm({Key key, this.initProfile}) : super(key: key);
@override
ProfileFormState createState() => ProfileFormState();
}
class ProfileFormState extends State<ProfileForm> {
final _formKey = GlobalKey<FormState>();
List<String> genders = ['Male', 'Female'];
List<String> positions = ['SA', 'PSA', 'PS', 'VPS'];
String _fullName;
String _position;
String _gender;
String _number;
String _email;
String _urlName;
@override
void initState() {
if (widget.initProfile != null) {
_fullName = widget.initProfile.fullName;
_position = widget.initProfile.position;
_gender = widget.initProfile.gender;
_number = widget.initProfile.phone;
_email = widget.initProfile.email;
_urlName = widget.initProfile.urlName;
}
super.initState();
}
Profile save() {
if (_formKey.currentState.validate()) {
_formKey.currentState.save();
var profile = Profile(
fullName: _fullName,
position: _position,
gender: _gender,
phone: _number,
email: _email,
urlName: _urlName);
return profile;
}
return null;
}
@override
Widget build(BuildContext context) {
return Padding(
padding: EdgeInsets.all(12.0),
child: Form(
key: _formKey,
child: Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
ProfileTextFormField(
initialValue: _fullName,
labelText: 'Full name',
hintText: 'Please enter your full name',
validator: (value) => Validator.validateFullName(value),
textInputAction: TextInputAction.next,
textCapitalization: TextCapitalization.words,
onSaved: (value) => _fullName = value,
),
ProfileDropDownField(
initialValue: _position,
labelText: 'Position',
hintText: 'Please enter your position',
items: positions,
onSelected: (value) => _position = value),
ProfileTextFormField(
initialValue: _number,
labelText: 'Phone number',
hintText: 'Please enter your phone number',
validator: (value) => Validator.validatePhone(value),
keyboardType: TextInputType.phone,
textInputAction: TextInputAction.next,
onSaved: (value) => _number = value,
),
ProfileTextFormField(
initialValue: _email,
labelText: 'Email',
hintText: 'Please enter your email',
validator: (value) => Validator.validateEmail(value),
keyboardType: TextInputType.emailAddress,
textInputAction: TextInputAction.next,
onSaved: (value) => _email = value,
textCapitalization: TextCapitalization.none,
),
ProfileRadioField(
initialValue: _gender,
labelText: 'Gender',
items: genders,
onSelected: (value) => _gender = value,
),
ProfileTextFormField(
initialValue: _urlName,
labelText: 'URL name',
hintText: 'Your preferred URL name',
textInputAction: TextInputAction.done,
onSaved: (value) => _urlName = value,
textCapitalization: TextCapitalization.none,
),
])),
);
}
}
我设法解决了这个问题，直接把TextFormField直接放在ListView里面。这是我唯一能让它正常工作的方法。
@override
Widget build(BuildContext context) {
return Form(
key: _formKey,
child: ListView(
padding: const EdgeInsets.all(8.0),
children: <Widget>[
widget.header ?? SizedBox.shrink(),
..._buildContentList(),
widget.footer ?? SizedBox.shrink(),
],
));
}
List<Widget> _buildContentList() {
var list = <Widget>[];
if (widget.hasProfile) list.addAll(_buildProfileFormList());
if (widget.hasStory) list.addAll(_buildStoryFormList());
return list;
}
List<Widget> _buildProfileFormList() {
return <Widget>[
ProfileTextFormField(
initialValue: _profile.fullName,
labelText: 'Full name',
hintText: 'Please enter your full name',
validator: (value) => Validator.validateFullName(value),
textInputAction: TextInputAction.next,
textCapitalization: TextCapitalization.words,
onSaved: (value) => _profile.fullName = value,
),
ProfileDropDownField(
initialValue: _profile.position,
labelText: 'Position',
hintText: 'Please enter your position',
items: positions,
onSelected: (value) => _profile.position = value),
ProfileTextFormField(

onSaved: (value) => _profile.phone = value,
),
ProfileTextFormField(

ProfileTextFormField(

hintText: 'Your preferred URL name',
textInputAction: TextInputAction.done,
onSaved: (value) => _profile.urlName = value,
textCapitalization: TextCapitalization.none,
),
];
}
List<Widget> _buildStoryFormList() {
return <Widget>[
ProfileTextFormField(
initialValue: _profile.aboutYourself,
labelText: '',
hintText:
'',
textInputAction: TextInputAction.next,
textCapitalization: TextCapitalization.sentences,
keyboardType: TextInputType.multiline,
onSaved: (value) => _profile.aboutYourself = value,
maxLines: 3,
),
ProfileTextFormField(
initialValue: _profile.sharingMessage,
labelText: '',
hintText: '',
keyboardType: TextInputType.multiline,
textInputAction: TextInputAction.done,
maxLength: 300,
onSaved: (value) => _profile.sharingMessage = value,
maxLines: 5,
),
];
}
