如何将两个ListView放在一列中? [英] How to put two ListView in a column?

问题描述

我有两个带有ExpansionTiles的ListView，我想一个接一个地放置在一个列中，该列中首先有其他一些Widget.这是我的代码，

I have two ListView with ExpansionTiles that I would like place one after another inside a column which has some other Widgets first inside it. This is my code,

 @override
 Widget build(BuildContext context) {
// TODO: implement build
return new Scaffold(
    appBar: new AppBar(
        title: new Text("Project Details"),
        backgroundColor: Colors.blue[800]),
    body:

    new Padding(padding: new EdgeInsets.all(10.0),
      child: new Column(children: <Widget>[
        new Text(project.name, style: new TextStyle(
            fontWeight: FontWeight.bold,
            color: Colors.blue[700],
            fontSize: 15.0
        )),
        new RowMaker("District", project.district),
        new RowMaker("River", project.river),
        new RowMaker("Tac Approved", project.tacApproved),
        new RowMaker("Func Sanctioned", project.fundSanctioned),
        new Row(children: <Widget>[
          new FlatButton(onPressed: null,
            color: Colors.blue,
            child: new Text("Gallery"),
            textColor: Colors.white,),
          new FlatButton(onPressed: null,
              color: Colors.blue,
              child: new Text("Upload Images"),
              textColor: Colors.white),
          new FlatButton(
              onPressed: null,
              color: Colors.blue,
              child: new Text("Update"),
              textColor: Colors.white),
        ],),
        new ListView(children: getSfListTiles()),
        new ListView(children: getWorkStatementTiles())


    ]
        ,
      )
      ,
    )
);

}

使用它，窗口小部件主体显示为空白.如果我直接将ListView设置为主体，则它们显示得很好.我想念什么吗?

Using this, widget body shows blank.If I set ListView directly as body, they show up fine. Am I missing something ?

推荐答案

尝试将 ListView 包装在 Expanded 中.它没有固有高度，因此您需要给它一个高度.

Try wrapping your ListView in Expanded. It doesn't have an intrinsic height so you need to give it one.
