我想显示一个选项弹出窗口,例如点击操作按钮上的图像(3 ...图标).

    android:icon="@drawable/ic_dealroom_details_normal"
    app:showAsAction="never" />

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context=".MainActivity">

    <item
        android:id="@+id/action_more"
        android:icon="@drawable/ic_more_white"
        android:title="@string/action_more"
        android:orderInCategory="100"
        app:showAsAction="always">
        <menu>
            <item
                android:id="@+id/action_settings"
                android:icon="@drawable/ic_settings_black"
                android:title="@string/action_settings"
                android:orderInCategory="100"
                app:showAsAction="never" />

            <item ... />
        </menu>

    </item>

</menu>
