问题 When displaying tabular data, I think that in some cases having an always visible header row and an always visible first column can really improve the readability and the overall usability of a table, especially if there is a lot of data in the table. The problem occurs when the table has to support both horizontal and vertical scrolling. A good example of such a table can be found from the NBA application when viewing box score of a past game. Here's an example image from the NBA Android

SwiftUI: Make ScrollView scrollable only if it exceeds the height of the screen

Deadly 提交于 2020-06-29 04:04:47
问题 Currently I have a view that looks like this. struct StatsView: View { var body: some View { ScrollView { Text("Test1") Text("Test2") Text("Test3") } } } This renders a view that contains 3 texts inside a scroll view, whenever I drag any of these texts in the screen the view will move cause its scrollable, even if these 3 texts fit in the screen and there is remaining space. What I want to achieve is to only make the ScrollView scrollable if its content exceeds the screen height size, if not,

Masonry list style in Xamarin

问题 I need to list the announcements on a content page just like masonry style (https://halcyon-theme.tumblr.com/) but I couldn't be successful on it. My problem is that the Scrollview doesn't cover whole the page when I use the Parent Stacklayout's Vertical alignment option set as FillAndExpand. But if I set the Scrollview and Parent StackLayout as static height value, It's okay but due to per item's height will change, I can't use it that's the way as you guess. <StackLayout x:Name="stckParent"

iOS 8.4: Scroll view resets contentOffset with Voice Over enabled shortly after view appear

被刻印的时光 ゝ 提交于 2020-06-24 13:42:47
问题 With Voice Over enabled scroll views reset their preset contentOffset a second after view did appear. It happens on iOS 8.4 devices, no reproduction for 9.0. Looks some internal UIScrollViewAccessibility code forces scroll view to setContent: for zero when becoming focused. Didn't find any way to evade this. Any thoughts? Related code sample illustrates the bug. Just create a view with collection view, create a cell with reuse id "Cell" and put a label on it. @interface ViewController ()
