我正在使用xamarin.forms和Rg.plugin.popup ......问题是：当我打开键盘时，弹出窗口被揉捏。然后，为了解决这个问题，我把所有代码放在ScrollView中，而在其他弹出窗口中它解决了问题，但只有在这个代码在上面的弹出窗口中，当我使用scrollView时，我的布局高度被拉伸了。

没有ScrollView：

使用ScrollView：

滚动可以滚动，没有任何意义，因为我的弹出窗口很小而且没有填满屏幕，或者我看不到它比我的屏幕尺寸大...... 有人可以帮忙吗？

我在网格中放置了'HeightRequest'并将其推入了stacklayout。我听说stacklayout只使用了nedded的大小，我不知道它是否属实，但是在这里工作。
