嵌套Listview，事件处理程序中的按钮不起作用

ListView.builder(
  itemCount: outerList.length,
  itemBuilder: (BuildContext context, int index) {
    return ListView.builder(
      shrinkWrap: true,
      physics: ClampingScrollPhysics(),
      itemCount: innerList.length,
      itemBuilder: (BuildContext context, int innerIndex) {
        return ListTile(
          title: Text(innerList[innerIndex]),
          trailing: RaisedButton(
            onPressed: () {
              // 处理按钮点击事件
            },
            child: Text('按钮'),
          ),
        );
      },
    );
  },
)

ListView(
  children: outerList.map((outerItem) {
    return GestureDetector(
      behavior: HitTestBehavior.translucent,
      onTap: () {
        // 处理外层item的点击事件
      },
      child: ListView(
        shrinkWrap: true,
        physics: ClampingScrollPhysics(),
        children: innerList.map((innerItem) {
          return ListTile(
            title: Text(innerItem),
            trailing: RaisedButton(
              onPressed: () {
                // 处理按钮点击事件
              },
              child: Text('按钮'),
            ),
          );
        }).toList(),
      ),
    );
  }).toList(),
)
