android-将开关按钮设置为带有showAsAction ="never"的操作栏. [英] android - Set switch button into action bar with showAsAction="never"

问题描述

我想使用showAsAction ="never"将一个切换按钮放入MenuItem中，但是它不起作用.这是我的布局

I want to put a switch button into MenuItem with showAsAction="never" but it's not working. Here is my layout

<?xml version="1.0" encoding="utf-8"?>
<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="com.trietnhm.multipleactivities.MainActivity"
    >


    <item
        android:id="@+id/action_about"
        android:orderInCategory="0"
        app:showAsAction="never"
        android:title="About"/>
    <item
        android:id="@+id/action_change_theme"
        android:orderInCategory="3"
        app:actionLayout="@layout/switcher"
        app:showAsAction="never"
        android:title="" />
    <item
        android:id="@+id/action_change_delimeter"
        android:orderInCategory="2"
        app:showAsAction="never"
        android:title="Change Delimeter"/>
</menu>

这是我的切换按钮

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <android.support.v7.widget.SwitchCompat
        android:id="@+id/switchForActionBar"
        android:layout_width="70dp"
        android:layout_height="50dp"
        android:scaleX="1.3"
        android:scaleY="1.3"
        android:switchMinWidth="45dp"
        android:paddingTop="6dp" />

</RelativeLayout>

当我运行该应用程序时，它什么也没有显示.此处的图像 https://drive.google.com/file/d/0B5zsq6J-qyY5bF8tYnBKVy11OHM/view?usp = sharing

When I run the app and it's not show anything. Here the image https://drive.google.com/file/d/0B5zsq6J-qyY5bF8tYnBKVy11OHM/view?usp=sharing

任何帮助，我将不胜感激.谢谢大家.

Any help I would be appreciated. Thanks all.

推荐答案

android:showAsAction

never:

切勿将此项放置在应用栏中.相反，请在 应用栏的溢出菜单.

Never place this item in the app bar. Instead, list the item in the app bar's overflow menu.

当然，它不会显示.也许您应该使用其他选项来显示always或ifRoom.

Of course, It won't show up. Perhaps you should use other options to show, always or ifRoom.
