Rg.Plugins.Popup is not closing when background is clicked in Xamarin.Forms

问题

I have used rg.plugins.popup in my application. I have updated the xamarin forms (version="2.5.0.121934"). Now the outer background is clicked it is not closed. I used to close the popup many ways, but not closed, I tried the below code:

this.CloseWhenBackgroundIsClicked = false;

protected override bool OnBackgroundClicked()
        {
            Navigation.PopPopupAsync();
            return false;
        }   

OnBackgroundClicked is not calling. How to fix this issue?

回答1:

I don't understand if you know that the correct code is: this.CloseWhenBackgroundIsClicked = true; (not false), but if this is not working you could try a workaround until this problem is solved.

Basically, add a Grid as the root of your PopupPage and add a Colorless BoxView with a TapGestureRecognizer as a child of the Grid, then just add the actual content as another child of the Grid and set the Tapped of the TapGestureRecognizer to the "BackgroundClicked" code.

Hope it helps!

I had the same problem, in my case it was about not understanding how this plugin works. First time I used the popup I placed a StackLayout on the center of the screen with this.CloseWhenBackgroundIsClicked = true and it worked pretty well, the problem was when I placed a GridLayout with columns 10*, 80*, 10* and rows 10*, 80*, 10*. my content was going in grid.rows(1), grid.columns(1). the other lines and columns were just borders. If I clicked the borders it would'nt work because I was touching the grid sides and not the actually background. The solution was change Grid for stacklayout and center it.

At first, I put all my StackLayout in a ScrollView and I had the same problem. Then I remove the ScrollView and it works.
