在onResume函數中添加password.setText（「」）後，爲什麼editText無法輸入？

Question

我做了一個Android應用程序。其中一個部分是登錄。在這個活動中，我有一個名爲密碼的EditText。按登錄按鈕後，它會打開一個新的活動，準備做其他事情。如果驗證服務器上的密碼失敗，我將完成（）新的活動並返回到舊的活動。我想清除已輸入的密碼。所以我在onResume（）方法中使用password.setText（「」）。

但是如果我多次輸入錯誤的密碼，如你所見，活動打開和關閉幾次，EditText上密碼無法輸入任何東西，直到我關閉活動，然後再次打開它。

這裏是logcat的信息：

有人知道爲什麼嗎？ 順便說一句：如果我刪除password.setText（「」）部分。它會正常工作。
