在AlertDialog解雇后，Edittext越来越受到关注并显示键盘

如何解决在AlertDialog解雇后，Edittext越来越受到关注并显示键盘

我在一个片段和一个AlertDialog中都有一个EditText。我正在使用EditText，然后单击完成按钮。但是，每当我关闭AlertDialog时，Edittext就会获得焦点并显示键盘。我不想在AlerDialog关闭后显示键盘。我该如何解决？

我在关闭AlertDialog后使用了val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager imm.hideSoftInputFromWindow(view.windowToken,0)，但是没有用。
