Android：点击外部ActionMode对话框时关闭浮动ActionMode

我遇到了一个我就是找不到答案的问题

在处理自定义视图中的内联列表组件中的

longClick（）

操作时，我使用的是浮动操作菜单。像这样：

当我显示动作菜单（使用

ActionMode.Callback2

）时，我无法通过点击动作菜单外的按钮来消除它

我正在寻找一个类似Chrome应用程序的解决方案（见下面的视频）：

我尝试过不同的解决方案，例如使用

View.onTouch（）

/

MotionEvent.ACTION\u外部

，

TouchDelegate（）

和另一种使用

registerForContextMenu（）

，但都不起作用

所以我想知道是否有人知道如何制作

ActionMode.Callback2

disclose当在它包含的视图之外单击时，任何帮助都将不胜感激。我的

ActionMode.Callback2

实现如下所示：

@RequiresApi(Build.VERSION_CODES.M)
class SampleViewItemActionModeCallback private constructor(private val sample: Sample,
                                                           private val listener: SampleView.SampleItemClickListener?,
                                                           private val touchDelegate: TouchDelegate? = null,
                                                           @MenuRes private var menuResId: Int = 0,
