[英]How to set text in one line for flutter
我在第4行文本字段中有用於下一個的flutter / dart代碼:
Container(
margin: EdgeInsets.all(8.0),
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
children: <Widget>[
Container(
width: 100.0,
child: TextField(
maxLength: 2,
onChanged: (value) {
card.expMonth = int.parse(value);
},
keyboardType: TextInputType.number,
textAlign: TextAlign.center,
decoration: InputDecoration(
border: InputBorder.none, hintText: 'month'),
)),
Text("/",
style: TextStyle(fontSize: 36),
textAlign: TextAlign.center),
Container(
width: 100.0,
child: TextField(
maxLength: 2,
onChanged: (value) {
card.expYear = int.parse(value);
},
keyboardType: TextInputType.number,
textAlign: TextAlign.center,
decoration: InputDecoration(
border: InputBorder.none, hintText: 'year'),
)),
Container(
padding: EdgeInsets.only(left: 80.0),
width: 180.0,
child: TextField(
maxLength: 3,
onChanged: (value) {
card.cvc = int.parse(value);
},
keyboardType: TextInputType.number,
textAlign: TextAlign.center,
decoration: InputDecoration(
border: InputBorder.none, hintText: 'cvc'),
)),
],
),
)
如何將所有文本字段都放在一行中。 在android應用中,我簡單地使用指南或其他簡單路徑。 在這里,我用撲朔迷離的現實來粉碎,其中不同的文本字段具有相同的可見性,乍一看,這些參數
UPD .:我提供拐杖解決方案:
Padding(
padding: EdgeInsets.only(bottom: 20),
child: Text("/",
style: TextStyle(fontSize: 36),
textAlign: TextAlign.center),
),
但是我的想法很愚蠢
這就是我要做的:
Row(children: <Widget>[
Expanded(
child: TextField(
inputFormatters: [LengthLimitingTextInputFormatter(2)],
keyboardType: TextInputType.number,
textAlign: TextAlign.center,
decoration: InputDecoration(
border: InputBorder.none, hintText: 'month'),
)),
Expanded(
child: Text("/",
style: TextStyle(fontSize: 36),
textAlign: TextAlign.center)),
Expanded(
child: TextField(
inputFormatters: [LengthLimitingTextInputFormatter(2)],
keyboardType: TextInputType.number,
textAlign: TextAlign.center,
decoration: InputDecoration(
border: InputBorder.none, hintText: 'year'),
)),
Expanded(
child: TextField(
inputFormatters: [LengthLimitingTextInputFormatter(3)],
keyboardType: TextInputType.number,
textAlign: TextAlign.center,
decoration: InputDecoration(
border: InputBorder.none, hintText: 'cvc'),
)),
])
產生此結果:
我使用了inputFormatters: [LengthLimitingTextInputFormatter(2)]
而不是maxLength
以便用戶仍然只能輸入有限的長度,但是由於看上去很整潔,因此您無法在TextField
下方找到計數器。
