環境
ユーザーがアクティビティ内のカードビューの名前をすばやく変更できるように、popupwindows を使用しています。
これを行うには、a を使用して(元の名前) を(新しい名前)ViewSwitcherに交換します。TextViewEditText
問題
確認するEditTextとPopUpWindowが表示され、ユーザーが を押す"RECENT APPS"と、何らかの理由でアプリに戻ることができません。すなわち。クリックしても反応しません。
診断
Window Focus の問題だと思います。私はEditText.clearFocus()ET から試して、すべての PopUps を却下しましたonPauseが、うまくいきません。
この問題を解決するために onFocusChangeListener を使用する方法はありますか?
