Android actionLayout未与工具栏一起显示

我正在尝试将自定义布局显示为选项菜单中的一项. 这是我到目前为止所做的

I'm trying to show custom layout as an item in options menu. And this is what I have done so far

<item
    android:id="@+id/action_profile"
    android:orderInCategory="100"
    android:title="Profile"
    android:actionLayout="@layout/layout_menu_profile"
    app:showAsAction="never" />

我尝试了

    app:actionLayout="@layout/layout_menu_profile"

以及此 SO链接，但仍仅显示标题-个人资料

as well as per this SO link but still it shows only title - Profile

我通过具有空白活动的Android Studio 1.5创建了新项目. minSDK = 15，targetSDK = 23

I have created new project through Android Studio 1.5 with Blank Activity. with minSDK = 15 and targetSDK = 23

以下是空白活动"中的代码.

Following is the code in Blank Activity.

@Override
 public boolean onCreateOptionsMenu(Menu menu) {

    getMenuInflater().inflate(R.menu.menu_home, menu);

    MenuItem item = menu.findItem(R.id.action_profile);


    return true;
}

我要去哪里错了?
