benim FavouritesViewModel olduğunu

Sorunumun belirtileri Görünüm "(x) Kaldır" düğmesine tıklandığında DeleteFavouriteMessage'ı alır. Öğeye tıklandığında, ItemClick olayı ShowFavouriteCommand, MvxListView'den kovulmaz.

Eminim ki bir şey yapıyorum ya da basit bir şey eksik, ama herhangi bir ilerleme kaydetmeye çalışıyorum.

Answer 1

eksik olduğunu düşünüyorum. MvxItemTemplate düzeninizdeki düğme odaklanıyor. Düzeninizdeki düğme için android:focusable="false" ayarlamayı deneyin. Bu cevabı güncelleştiriyorum

Changing focus from Button in ListView row to list item

daha kapsamlı olması. ListView Öğesinde ortak bir Düğme denetimi için android:focusable="false" öğesi ayarlanırken sorun düzeltildi. Bir ImageButton kullanıyorsanız, bu işe yaramaz.

ImageButton için, düzeninizin kök görünümünde android:descendantFocusability="blocksDescendants"'u ayarlamanız gerekir. can't click on listview row with imagebutton

Answer 2

Sana bunu daha önce karşılaştığınız android:choiceMode="singleChoice"

<Mvx.MvxListView 
       local:MvxBind="ItemsSource Favourites; ItemClick ShowFavouriteCommand" 
       ... 
       android:choiceMode="singleChoice" 
       android:id="@+id/listFavourites" />
