Question

我想将 onTap 添加到我的水平 ListView 中的每个类别，我该怎么做呢？

class HorizontalList extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Container(
      height: 80.0,
        child: ListView(
        scrollDirection: Axis.horizontal,
        children: <Widget>[
          Category(
            image_location: "catogories/name.png",
            ),
          ],
      ),
    );

您可以使用 GestureDetector 包装您的类别小部件小部件。

class HorizontalList extends StatelessWidget {
      @override
      Widget build(BuildContext context) {
        return Container(
          height: 80.0,
            child: ListView(
            scrollDirection: Axis.horizontal,
            children: <Widget>[
            GestureDetector(
              onTap: () {
                //This will be called on tap 
              },
              child:Category(
                image_location: "catogories/name.png",
              ),
            ),
            ],
          ),
        );
     }}
