long-press

问题 I have a custom listview , in which items are scroll horizontal . I want to perform single touch and longpress for items for 5 sec for listview items. How to do this. How can i increase longpress time interval for listview items to 5 sec. 回答1: This replicates onLongPress more accurately because it does not wait for the user to lift their finger before executing.

问题 I want to be able to reorder tableview cells using a longPress gesture (not with the standard reorder controls).

问题 I'm building an iPhone app that would let the user rearrange some of the UI elements on the screen. How can I add a tap gesture recognizer and a long press gesture recognizer to the same UIView? When I lift up the finger from the long press, the tap gesture recognizer fires.

For your own EditText widgets, you can use setCustomSelectionActionModeCallback()

问题 I'm using this solution for handling the long tap event: https://alexdunn.org/2017/12/27/xamarin-tip-xamarin-forms-long-press-effect/ It works fine when I use XAML, but I need to use code behind only.

问题 I have a button in SwiftUI and I would like to be able to have a different action for "tap button" (normal click/tap) and "long press". Is that possible in SwiftUI? Here is the simple code for the button I have now (handles only the "normal" tap/touch case).
