长按溢出菜单的子菜单项

Question

我正在处理 android 应用程序中具有溢出菜单的项目。在 onCreateOptionsMenu() 中，我根据用户详细信息动态更新菜单和子菜单，但任务要求我对该菜单按钮进行 2 次操作，我已经通过 [=22 进行了一次单击=]onOptionsItemSelected()

是否可以将类似 OnLongClickListener 的内容添加到溢出菜单的子菜单项中？

在我的菜单中XML我这样设置subItem

<item
android:id="@+id/help"
android:orderInCategory="101"
android:title="Help"
app:actionViewClass="android.widget.ImageButton"
app:showAsAction="never" >
<menu xmlns:android="http://schemas.android.com/apk/res/android"        xmlns:HTMLCode="http://schemas.android.com/apk/res-auto" >
    <item android:id="@+id/event1"
        android:title="Event 1"
        app:actionViewClass="android.widget.TextView"
        HTMLCode:showAsAction="ifRoom|withText" />
    <item android:id="@+id/event2"
        android:title="Event 2"
        app:actionViewClass="android.widget.TextView"
        HTMLCode:showAsAction="ifRoom|withText" />
    <item android:id="@+id/event3"
        android:title="Event 3"
        app:actionViewClass="android.widget.TextView"
        HTMLCode:showAsAction="ifRoom|withText" />
</menu>

然后在 onCreateOptionsMenu 中我像这样附加 longClick

    var helpMenuItem = menu.findItem(R.id.help)
helpMenuItem.subMenu?.let { subMenu ->
    val ct = subMenu.size()
    for (i in 0 until ct) {
        val subItem = subMenu.getItem(i)
        subItem.actionView?.let { view ->
            view.setOnLongClickListener {
                Log.d("Long Click Event", "I'm here!!")
                true
            }
        }
    }
}

代码可以编译，但我始终无法获得 onLongClick。求助这几天一直在找解决方案wo luck

所以没有人回答，但我需要完成它，所以我继续挖掘。这是我想出的解决方法。我没有保留子菜单的工具栏菜单，而是创建了一个新对话框，在那里我覆盖并添加了我的 onClick 和 LongClick。这对我有用，没有别的。

private fun displayPopupDialog() {
    val context = applicationContext
    val buds = myArray.toTypedArray<CharSequence>()
    val builder: AlertDialog.Builder = AlertDialog.Builder(this)
    builder.setTitle("Select a Buddy")
    builder.setItems(buds, object : DialogInterface.OnClickListener {
        override fun onClick(dialogInterface: DialogInterface?, item: Int) {
            //  showShortToast("Clicked on:"+buddy[item]);
            val ptcode = buds[item].toString()
                clickFromDialog("code: $ptcode")
            return
        }
    })
    val ad = builder.create() //don't show dialog yet
    ad.setOnShowListener(object : DialogInterface.OnShowListener {
        override fun onShow(dialog: DialogInterface?) {
            val lv = ad.listView //this is a ListView with your "buds" in it
            lv.setOnItemLongClickListener(object : AdapterView.OnItemLongClickListener {
                override fun onItemLongClick(
                    parent: AdapterView<*>?,
                    view: View?,
                    position: Int,
                    id: Long
                ): Boolean {
                    var textOnView = (view as MaterialTextView).text
                    Log.d("Long Click!", "List Item #" + position + " $textOnView was long clicked")
                    return true
                }
            })
        }
    })


    val window: Window? = ad.getWindow()
    val wlp: LayoutParams? = window?.getAttributes()
    wlp?.gravity = Gravity.RIGHT or Gravity.TOP
    window?.setAttributes(wlp)
    ad.show()
}

private fun clickFromDialog(ptcode: String) {
    Log.d("Click!", "List Item $ptcode was clicked")
}
