  child: GridView(
    gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
      crossAxisCount: 4, //列数
      mainAxisSpacing: 2.0, //行间距
      crossAxisSpacing: 2.0, //列间距
      childAspectRatio: 0.8, //宽高比 宽相对于高的倍数
    ),
    children: <Widget>[
      new Image.network(
        'http://img31.mtime.cn/mt/2014/03/07/123549.37376649_96X128.jpg',
