ListView ItemClick沒有響應

Question

我有我的主要活動佈局內的ListView控件。在ListView中的每個項目上，我都有一個用於查看詳細信息（打開新活動）和查看地圖（打開外部谷歌地圖應用程序）的按鈕。我遇到的問題是我希望用戶能夠點擊ListView項目本身（而不是按鈕），以便可以更新地圖（位於ListView上方的片段內）。出於某種原因，當我點擊ListView項目時，我的ListView.itemclick事件不會執行。我需要添加一些東西到我的代碼才能使這個工作？我搜索了網頁，發現了一些修復此問題的建議，但沒有任何效果。

我終於找到了這個問題的答案在這個網站：

https://forums.xamarin.com/discussion/871/how-do-i-get-itemclick-of-a-listview-to-get-called-not-sure-what-have-wrong

則必須將這些屬性值添加到按鈕上的列表視圖項目。

var imageButton = view.FindViewById<ImageButton>(Resource.Id.imageButton1); 
imageButton.Focusable = false; 
imageButton.FocusableInTouchMode = false; 
imageButton.Clickable = true;
