如何在 TimePicker 中关闭键盘图标？

Question

I have a timepicker, everything works well but the problem is that I can't make it look like designer wants. For now it looks like this:

I need to hide this keyboard icon under the buttons. How can I do it? It's just a prototype, so here's only its xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:orientation="vertical"
  android:tag="ww">

  <TextView
    android:id="@+id/textView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Time"
    android:textAppearance="?android:attr/textAppearanceLarge" />

  <TimePicker
    android:id="@+id/timePicker"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:amPmBackgroundColor="#6400AA"
    android:numbersSelectorColor="#6400AA" />

  <LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="end"
    android:orientation="horizontal">

    <Button
      android:id="@+id/button2"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:text="Cancel"
      android:textColor="#6400AA" />

    <Button
      android:id="@+id/button1"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:text="OK"
      android:textColor="#6400AA" />

  </LinearLayout>

</LinearLayout>

我刚刚在布局检查器中检查了层次结构，发现了那个键盘图标。对于纵向和横向层次结构是不同的，因此我们对此进行了方向检查，并且还从 Oreo 进行了 OS 检查（来自 Oreo 仅此图标可用），我尝试了此代码并且它工作正常。PS：科特林代码

    fun hideKeyboardInputInTimePicker(orientation: Int, timePicker: TimePicker)
    {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
        {
            try
            {
                if (orientation == Configuration.ORIENTATION_PORTRAIT)
                {
                    ((timePicker.getChildAt(0) as LinearLayout).getChildAt(4) as LinearLayout).getChildAt(0).visibility = View.GONE
                }
                else
                {
                    (((timePicker.getChildAt(0) as LinearLayout).getChildAt(2) as LinearLayout).getChildAt(2) as LinearLayout).getChildAt(0).visibility = View.GONE
                }
            }
            catch (ex: Exception)
            {
            }

        }
    }

像这样打电话

hideKeyboardInputInTimePicker(this.resources.configuration.orientation, startTimePicker)

据我所知，您无法删除此图标，它是 Android O 上 UI 的一部分。

该图标的存在是为了使手动编辑时间更加明显，因为在以前的版本中，您可以单击时间并通过键盘更改它并不明显
