Question

我有一个包装在列表视图中的容器列表，我需要提供一个onTap功能，例如当用户点击容器时，它应该为我提供该特定容器的值，以下是我的代码，我尝试使用Inkwell函数但是它抛出一个错误，说垂直端口视图。帮帮我，谢谢。

dynamic _allVehiclesDataView = new ListView(
  children: List.generate(this._allVehiclesData.length,
    (i) => new Container(
      decoration: new BoxDecoration(
        border:  Border(
          bottom:  BorderSide(width: 1.0, color: Colors.grey[300]),
        ),
      ),
      padding: const EdgeInsets.all(32.0),
      child: Row(
        children: [
          Expanded(
            child: Column(
              crossAxisAlignment: CrossAxisAlignment.start,
              children: [
                Container(
                  padding: const EdgeInsets.only(bottom:5.0),
                  child: Text(
                    this._allVehiclesData[i]["vehicle"]["registration"],
                    style: TextStyle(

您可以将GestureDetector用于同一

通过onTap回调将Container包裹在GestureDetector中

GestureDetector(
  // When the child is tapped, do your work
  onTap: () {
    ...
    ...
  },
  // Container
  child: Container(
    ...
  ),
);
