Flutter:如何在Listview中删除行之间的空间 [英] Flutter : How to remove space between row in Listview

问题描述

我只是在做一些抖动的演示，我喜欢这样做，在列表视图中，我找不到如何删除行之间的空间

I am just doing some demos of flutter, I love to do it, In listview, I cant find out that how to remove space between rows

我的代码非常简单，这是一个小部件，我返回到自己的布局

my code is pretty simple, This one is Widget which I return to my layout

Widget _getWidget(BuildContext context) {
return new Material(
    child: new Container(
      padding: EdgeInsets.only(top: 20.0),
      color: Colors.blueGrey[500],
      child: new Column(
        crossAxisAlignment: CrossAxisAlignment.start,
        children: <Widget>[
          _getHeader(context),
          new Expanded(child: getListView())
        ],
      ),
    ),
);

}

这是Listview

This one is Listview

 ListView getListView() =>
      new ListView.builder(
          itemCount: widgets.length,
          itemBuilder: (BuildContext context, int position) {
            return getRow(position);
          });

这是我使用卡片视图的行

This one is row which i use card view

 Widget getRow(int i) {
    return new Padding(padding: new EdgeInsets.all(10.0),
        child: new Card(
          child: new Column(
            children: <Widget>[
              new ListTile(
                title: new Text(
                    "Name : ${widgets[i].username}"
                ),
                subtitle: new Text(
                    "Decription : You may go now!!"
                ),
              ),
              new ButtonTheme.bar(
                child: new ButtonBar(
                  children: <Widget>[
                    new FlatButton(
                      child: const Text('Accept'),
                      onPressed: () { /* ... */ },
                    ),
                    new FlatButton(
                      child: const Text('Reject'),
                      onPressed: () { /* ... */ },
                    ),
                  ],
                ),
              ),
            ],
          ),
        )
    );
  }

救救我.

推荐答案

在卡片之间获得的空格来自 getRow()方法.

The spaces that you are getting between cards is from getRow() method.

只需更新

new Padding(padding: new EdgeInsets.all(10.0),

到

new Padding(padding: new EdgeInsets.all(1.0),

并查看更改.

如果您不想在它们之间留任何空格，可以直接返回Card();

If you don't want any spaces in between, you can directly return Card();
