如何将 ContentView 添加到 Click 事件？

Question

我的任务是创建一个程序，在主屏幕上显示两个按钮以及我的姓名和当前时间/日期。目标是一旦按下其中一个按钮就会出现一个段落，这将利用整个屏幕。到目前为止，我已经创建了带有标签和按钮的主页。但是，对于如何显示与单击的按钮相关的段落，我非常迷茫。我正在使用经验拟合的文本方式来充分利用屏幕。我创建了一个 FontCalc.Cs 页面并在我拥有所有代码的主页中添加了 onContentViewSizeChanged 方法。我不知道下一步该怎么做。到目前为止，这就是我在点击处理程序事件中的内容：

        passage1Button.Clicked += (sender, args) =>
        {
            passage.Text = "So they began working together, each squadron leader commanding indivual pilots, " +
                           "Ender comanding the squadron leaders. They learned manyw ays of working together, " +
                           "as the simulator forced them to try different situations. Sometimes the simulator " +
                           "gave them a larger fleet to work with; Ender set them up then in three or four " +
                           "toons that consisted of three or four squadrons each. Sometimes the simulator gave " +
                           "them a single starship with its twelve fighters, and he chose three sqaudron leaders. ";

            ContentView contentView = new ContentView
            {
                Content = passage
            };
            contentView.SizeChanged += onContentViewSizeChanged;

它不会在按钮消失的同时显示段落，它只会冻结 android 模拟器和 UWP 本地计算机。

您可以在按钮单击时显示模式

        passage1Button.Clicked += (sender, args) =>
         {
            var contentpage = new ShowTextPage("Passage text here, goes to page constructor where label is set to passed text");

            var page = new NavigationPage(contentpage);

            Navigation.PushModalAsync(page);
         }

在 ShowTextPage 上，将 HasNavigationBar 设置为 false
