大佬教程收集整理的这篇文章主要介绍了android – 在ActionBar中的菜单项上添加复选框，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

我的操作栏中有问题.我正在尝试在ActionBar中的菜单项上添加一个复选框,但它不起作用.它只显示复选框的标题.

这是我的menu.xml：

<menu xmlns:android="http://scheR_715_11845@as.android.com/apk/res/android"
    xmlns:app="http://scheR_715_11845@as.android.com/apk/res-auto"
    xmlns:tools="http://scheR_715_11845@as.android.com/tools"
    tools:context="com.tracking.bus.maps.SingleViewMapsActivity" >

        <item
        android:id="@+id/actionbar_alarm"
        android@R_505_6964@="@String/actionbar_alarm"
        app:actionViewClass="android.widget.checkBox"
        app:showAsAction="ifRoom"/>
</menu>

解决方法

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://scheR_715_11845@as.android.com/apk/res/android">

    <!-- checkable items appear only in submenus or context menus. -->

    <!-- Carefully look at the attribute name checkableBehavior on groups,but
         the attribute name checkable on items. The checkableBehavior encompasses
         the number of items that will be checkable within that group. -->

    <item android@R_505_6964@="None">
        <menu>
            <!-- The none checkableBehavior is default,but we explicitly show it here. -->
            <group
                android:id="@+id/noncheckable_group"
                android:checkableBehavior="none">
