Navigation.PushModalAsync在xamarin表單內的Tapgesture中給出的時候不工作

Question

var tapGestureRecognizer1 = new TapGestureRecognizer(); 

sub_header.GestureRecognizers.Add(tapGestureRecognizer1); 

tapGestureRecognizer1.Tapped += (s, e) => 
{ 
          Navigation.PushModalAsync(new DisplayContent()); 
}; 

這裏sub_header是一個標籤，輕擊手勢給了它。雖然調試控件將進入'DisplayContent'頁面，但視圖仍在同一頁面中。誰能幫忙？

改變你的代碼如下

var tapGestureRecognizer1 = new TapGestureRecognizer(); 
tapGestureRecognizer1.Tapped += (s, e) => 
        { 
         Navigation.PushModalAsync(new DisplayContent()); 
        }; 

sub_header.GestureRecognizers.Add(tapGestureRecognizer1);
