如何在 android 操作菜单中显示带文本的图标列表，如图像

Question

我想在点击操作按钮（3 ... 图标）时显示一个选项弹出窗口，如图片所示。

我尝试通过选项菜单来完成，但图标没有出现。请建议我如何添加图标。

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

<item
    android:id="@+id/action_view_details"
    android:title="View room details"
    android:orderInCategory="100"
    android:icon="@drawable/ic_dealroom_details_normal"
    app:showAsAction="never" />

<item
    android:id="@+id/action_add_file"
    android:title="@string/action_create_file"
    android:orderInCategory="100"
    android:icon="@drawable/ic_dealroom_createfolder_normal"
    app:showAsAction="never" />

<item
    android:id="@+id/action_add_folder"
    android:title="@string/action_create_folder"
    android:icon="@drawable/ic_dealroom_createfile_normal"
    android:orderInCategory="100"
    app:showAsAction="never" />

<item
    android:id="@+id/action_upload_from_camera"
    android:title="@string/action_upload_from_camera"
    android:icon="@drawable/ic_dealroom_uploadcamera_normal"
    android:orderInCategory="100"
    app:showAsAction="never" />

<item
    android:id="@+id/action_upload_from_gallery"
    android:title="@string/action_upload_from_gallery"
    android:icon="@drawable/ic_dealroom_uploadgallery_normal"
    android:orderInCategory="100"
    app:showAsAction="never" />
<item
    android:id="@+id/action_upload_from_local"
    android:title="@string/action_upload_from_local"

<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>

ic_more_white是3的图标... 希望对您有所帮助。
