How to prevent accessibility focus going behind a Rg.Plugins.Popup when running on Android?

John Hardman 261

When using Rg.Plugins.Popup, if an Android user is using Talkback, the accessibility focus can end up on Views that are behind the popup. Has anybody found a way of preventing this (e.g. is there a way of identifying the popup or the topmost View in the popup as being modal)?

Hi,JohnHardman-6852. In the Rg.Plugins.Popup library, the PopupPage provides the CloseWhenBackgroundIsClicked property which is set to true by default. When the property is ture, the PopupPage will be closed when clicking other place on the screen. The issue you described may be caused by this, you could set the property to false when initializing the popup page to prevent this behavior.

<pages:PopupPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" ... CloseWhenBackgroundIsClicked="False"> ... </pages:PopupPage>

Hi @JarvanZhang . Unfortunately changing CloseWhenBackgroundIsClicked doesn't make a difference to the accessibility focus (I've tried it with both true and false to check)..

You could report this issue to the author of the library on github to fix this issue.
