Question

我的列表视图在列底部有条码。

从列表视图开始的第一张图片是圆形的，但最后它显示为矩形。

滚动列表视图时 Chip 1 天溢出。（第二张图片）。

我想要两侧底部都需要圆形，如何实现？提前致谢。

我的代码

Container(
                padding: EdgeInsets.only(
                  top: 16.0,
                ),
                width: MediaQuery.of(context).size.width,
                height: 100,
                decoration: BoxDecoration(
                    borderRadius: BorderRadius.circular(12.0),
                    color: Colors.white),
                child: Column(
                  mainAxisAlignment: MainAxisAlignment.spaceBetween,
                  crossAxisAlignment: CrossAxisAlignment.start,
                  children: <Widget>[
                    Text(""),
                    Container(
                      height: 35,
                      decoration: BoxDecoration(
                          borderRadius: BorderRadius.only(
                              bottomLeft: Radius.circular(12.0),
                              bottomRight: Radius.circular(12.0)),
                          color:
                              Theme.of(context).chipTheme.backgroundColor),
                      child: ListView(
                        scrollDirection: Axis.horizontal,
                        children: getChoiceChips(),
                      ),
                    )
                  ],
                ),
              )

芯片功能

getChoiceChips() {
List<Widget> choiceChipList = [];
List<String> choiceString = [
  '1 Day',
  '1 Week',
  '1 Month',
  '3 Months',
  '1 Year'
];
for (String choice in choiceString) {
  choiceChipList.add(Padding(
    padding: const EdgeInsets.only(left: 2.0, right: 2.0),
    child: ChoiceChip(
      label: Text(choice),
      selected: choice == selectedChoice,
      onSelected: (newSelectedChoice) {
        setState(() {
          print(selectedChoice);
          print(newSelectedChoice);
          selectedChoice = choice;


          print(selectedChoice);
          print(choice);
        });
      },
    ),
  ));
}
return choiceChipList;
}

BoxDecoration中的Container只会将圆角显示为视觉特征。如果您想实际将内容剪辑到没有溢出的圆角内，您需要将容器包围在 ClipRRect.

中

ClipRRect(
  borderRadius: BorderRadius.circular(12.0),
  child: Container(
    padding: EdgeInsets.only(top: 16.0),
    width: MediaQuery.of(context).size.width,
    height: 100,
    decoration: BoxDecoration(color: Colors.white),
    child: Column(
      ...
    ),
  ),
),
