方案一：listView加上下面2个属性就解决了

//shrinkWrap和physics，在被Column或者SingleChildScrollView嵌套时候可以正常绘制
        shrinkWrap: true, 
        physics:ClampingScrollPhysics(),   

方案二：在Column里面等listview加上Expanded

Column(children:<Widget>[Container(),Expanded(child:ListView())]);

完整代码

  Widget buildPage(BuildContext context){

    widgetListviewFans(){
      if(_listFans==null || _listFans.length==0)
        return Center(child:(_loadTips==null||_loadTips.isEmpty)?Text(_defaultLoading):Text(_loadTips));

      return ListView.builder(
        scrollDirection: Axis.vertical,
        itemCount: _listFans.length,
        itemBuilder: (context,i){
          return buildItem(context, _listFans[i]);
        },
        padding: EdgeInsets.fromLTRB(_blockMargin,5,_blockMargin,5),
        //shrinkWrap和physics，在被Column或者SingleChildScrollView嵌套时候可以正常绘制
        shrinkWrap: true, 
        physics:NeverScrollableScrollPhysics(),   
      );
    }

    widgetEasyRefresh(){
      return
      EasyRefresh(
        child:SingleChildScrollView(
          child:Column(children:<Widget>[
            Container(child: Text('this test'), height: 20,width: 120,),     
            widgetListviewFans()
          ])
        ),
        header:refreshHeader,

        },
        onLoad: () async{
