两个页面，一个是用于菜单，一个是用于列表查询。
菜单 使用了 TabView，所有的代码写在了OnAppearing，但是它没有内容了。找了两天原因。在github提到这是一个bug。不会修复。但是可以在构造函数中加载，就不会有问题。
列表查询，我也放在了构造函数里面，但是绑定数据之后，数据显示错乱了。找了三天原因。然后改了写法。使用了
CollectionView，
原来的是写法是 CollectionView.ItemTemplate = new DataTemplate(new stacklayout()) new stacklayout在前面创建好的。
后面改成了 CollectionView.ItemTemplate = new DataTemplate(()=>{
return StackLayout();
});
首次，这样写，这句话的执行是在ItemSource赋值的时候才会处理。
然后，数据源是DataTable，所以ItemSource = DataTable.Rows，显示不了数据。
因为绑定不能 写 "列名",要写成ItemArray[序号]。所以这个要提前把顺序固定下来。
下面是我的垃圾代码。
