更改 DatePicker 或 TimePicker 时如何取消 EditText 中的焦点？

Question

我有设置文本、日期、时间的 DialogFragment。 当我显示此对话框时，已将注意力集中在 EditText 上。当我在 DatePicker 中设置日期时，将焦点移到 EditText 上。

我尝试向 EditText 添加参数，但没有帮助。无法输入文字。

android:focusable="false"
android:focusableInTouchMode="false"

在我找到一些解决方案后（如果按下“Enter” - 我禁用对 EditText 的关注）：

editTextComment.setOnKeyListener(new View.OnKeyListener() {
        public boolean onKey(View view, int keyCode, KeyEvent event) {
            if (keyCode == KeyEvent.KEYCODE_ENTER) {
                editTextComment.setFocusable(false);
                editTextComment.setFocusableInTouchMode(true);
                return true;
            } else {
                return false;
            }
        }
    });

你能帮我做对吗？谢谢。

添加

    android:editable="false"

到您的 EditText (dialog_add_comment) 并尝试。
