复制/粘贴的弹出菜单未以全尺寸显示答案

【问题标题】：Popup menu for Copy/Paste does not appear in full size复制/粘贴的弹出菜单未以全尺寸显示
【发布时间】：2018-10-29 11:52:31
【问题描述】：

当我双击或长按 EditText 中的文本时，带有复制/粘贴选项的 PopupMenu 不会以全尺寸显示。

我使用一个活动，它承载了详细消息的片段。我还尝试使用 Popup 的样式，但没有得到任何结果。

我在活动中使用的样式

<style name="AppThemeNoActionBar" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimaryDark">@color/black</item>
    <item name="colorAccent">@color/white</item>

    <item name="searchViewStyle">@style/AppSearchViewStyle</item>

    <!--Текст-->
    <item name="android:gravity">center</item>
    <item name="android:textColor">@color/gold</item>
    <item name="android:textSize">@dimen/general_text_size</item>
    <item name="android:fontFamily">@font/basis_grotesque_pro_regular</item>
    <item name="actionMenuTextColor">@color/white</item>

    <item name="popupMenuStyle">@style/MyPopup</item>
    <item name="android:popupMenuStyle">@style/MyPopup</item>
  </style>

  <style name="MyPopup" parent="Base.Widget.AppCompat.PopupMenu">
    <item name="android:popupBackground">@color/gold</item>
    <item name="android:textColor">@color/black</item>
    <item name="android:itemBackground">@color/white</item>
  </style>

  <style name="AppSearchViewStyle" parent="Widget.AppCompat.SearchView">
    <item name="queryBackground">@android:color/transparent</item>
    <item name="searchIcon">@drawable/search_icon</item>
    <item name="android:imeActionId">6</item>
  </style>

还有 onCreateView(...) 代码

override fun onCreateView(
    inflater: LayoutInflater,
    container: ViewGroup?,
    savedInstanceState: Bundle?
  ): View? {
    val view = inflater.inflate(R.layout.util_description_fragment, container, false)
    ButterKnife.bind(this, view)

    mWorkingDayAddHeader.text = "Текст события"
    mWorkingDayAddHeaderDetail.text = "Опишите максимально детально ваше событие"
    mWorkingDayAddButton.text = "Добавить событие"
    mWorkingDayAddRightSideText.text = "Борис"

    val wrapper = ContextThemeWrapper(activity!!, style.AppThemeNoActionBar)
    val popup = PopupMenu(wrapper, view)

    return view
  }

此外，您可能会提供一些有关代码质量的cmets，这可能非常有用。提前致谢

【解决方案1】：

val view = inflater.inflate(R.layout.util_description_fragment, container, false)
......
val popup = PopupMenu(wrapper, view)

根据上面的代码，这个弹出窗口的锚视图将是片段。不过应该是EditText吧？

【讨论】：

在我看来这并不重要，因为问题在于显示默认弹出菜单，而不是自定义它。谢谢））
