Android 从包含DialogFragment的片段向上导航将重新显示DialogFragment导航组件

我正在使用导航组件，我已经设置了向上箭头，以便在我唯一的活动

main活动中自动处理导航过程，我有：

override fun onOptionsItemSelected(item: MenuItem): Boolean {
    return item.onNavDestinationSelected(navController) || super.onOptionsItemSelected(item)
}

当用户从
StationsFragment
单击菜单项时，将显示该对话框，如下所示：

override fun onOptionsItemSelected(item: MenuItem): Boolean {
    val bundle = Bundle()
    bundle.putInt(GAME_ID_BUNDLE_KEY, gameId)
    findNavController().navigate(R.id.action_stationsFragment_to_gameInfoDialog, bundle)
    return true
}

<fragment
    android:id="@+id/stationsFragment"
    android:name="com.accad.accadgame.screens.fragments.StationsFragment"
    android:label="@string/stations_fragment_title"
    tools:layout="@layout/fragment_stations"
    >
    <argument
        android:name="game_id"
        app:argType="integer"
        android:defaultValue="-1" />
    <action
        android:id="@+id/action_stationsFragment_to_sectionsFragment"
        app:destination="@id/sectionsFragment"
        app:popUpTo="@+id/stationsFragment"
        app:popUpToInclusive="false" />
    <action
        android:id="@+id/action_stationsFragment_to_gameInfoDialog"
        app:destination="@id/gameInfoDialog"
        app:popUpTo="@id/stationsFragment"
        app:popUpToInclusive="false"
        />
</fragment>
<dialog
    android:id="@+id/gameInfoDialog"
    android:name="com.accad.accadgame.screens.dialogs.GameInfoDialog"
    android:label="GameInfoDialog"
    tools:layout="@layout/dialog_game_info"
    >
    <argument
        android:name="game_id"
        app:argType="integer"
        android:defaultValue="-1" />

我已经将导航图设置为：

override fun onOptionsItemSelected(item: MenuItem): Boolean {
    val bundle = Bundle()
    bundle.putInt(GAME_ID_BUNDLE_KEY, gameId)
    findNavController().navigate(R.id.action_stationsFragment_to_gameInfoDialog, bundle)
    return true
}

<fragment
    android:id="@+id/stationsFragment"
    android:name="com.accad.accadgame.screens.fragments.StationsFragment"
    android:label="@string/stations_fragment_title"
    tools:layout="@layout/fragment_stations"
    >
    <argument
        android:name="game_id"
        app:argType="integer"
        android:defaultValue="-1" />
    <action
        android:id="@+id/action_stationsFragment_to_sectionsFragment"
        app:destination="@id/sectionsFragment"
        app:popUpTo="@+id/stationsFragment"
        app:popUpToInclusive="false" />
    <action
        android:id="@+id/action_stationsFragment_to_gameInfoDialog"
        app:destination="@id/gameInfoDialog"
        app:popUpTo="@id/stationsFragment"
        app:popUpToInclusive="false"
        />
</fragment>
<dialog
    android:id="@+id/gameInfoDialog"
    android:name="com.accad.accadgame.screens.dialogs.GameInfoDialog"
    android:label="GameInfoDialog"
    tools:layout="@layout/dialog_game_info"
    >
    <argument
        android:name="game_id"
        app:argType="integer"
        android:defaultValue="-1" />



当我点击信息菜单项时，对话框会正常显示


当我关闭对话框并单击
站片段的向上箭头时，经过长时间搜索后，对话框再次显示，返回箭头也被视为一个菜单项

因此，当单击后退箭头时，将调用选项ItemSelected方法，需要检查菜单项id

代码为：

override fun onOptionsItemSelected(item: MenuItem): Boolean {
    if(item.itemId == R.id.gameInfo) {
        val bundle = Bundle()
        bundle.putInt(GAME_ID_BUNDLE_KEY, gameId)
        findNavController().navigate(R.id.action_stationsFragment_to_gameInfoDialog, bundle)
        return true
    }
    return super.onOptionsItemSelected(item)
}
