查看竊取可見性焦點，當變得可見

Question

在屏幕上，有一個ImageView有焦點。當新視圖通過coolNavbarView.setVisiblity(View.GONE)顯示時，新視圖將會關注焦點。如果用戶導航到新視圖，則該視圖應該能夠變得可以聚焦，但是一旦顯示它就不應該偷窺焦點。重點應放在已經有焦點的ImageView上。

我知道是一個setFocusable(boolean)方法讓視圖變得焦點，有沒有setStealFocusOnVisible(boolean)方法？

以下是它如何聚焦的堆棧跟蹤。

Answer 1

對我而言，ListView是偷竊焦點。我可以通過在使ListView可見之前從ListView中刪除Focusable屬性來修復它。

ListView v = ViewUtils.findViewById(view, listLayoutId, ListView.class); 
v.setFocusable(false);
