Question

我正在为我的应用程序实现材料设计。我用新的android工具栏替换了原生的ActionBar。添加了菜单项，onOptionsItemSelected完美运行。但是，当我单击溢出图标或具有多个菜单项的项目时，应用程序崩溃。

                    android:title="item1"/>
            <item
                    android:id="@+id/action_2"
                    android:title="item2"/>
        </menu>
    </item>

    <item
            android:id="@+id/action_about"
            android:title="About"
            android:icon="@android:drawable/ic_menu_help"
            Compat:showAsAction="never"/>

</menu>

崩溃后显示以下消息：

此外，我使用的是最新版本的appcompat库。我跟着教程，谷歌搜索，但没有找到任何东西。这次事故的原因是什么？请帮忙。

Answer 1

请在此处阅读.. http://developer.android.com/guide/topics/ui/menus.html 您刚刚创建了菜单，但尚未提供其功能。换句话说，你只是在屏幕上夸大菜单，没有提供功能，如果使用点击它们将会做什么。要启用它们，您需要实现以下方法，例如

</head>
<body>
    <div>
        <div id="form-container">
            <!--<input type="submit" id="searchsubmit" value="" />-->
            <a class="search-submit-button" href="javascript:void(0)">
                <i class="fa fa-search"></i>
            </a>
            <div id="searchtext">
                <input type="text" id="s" name="s" value="Search Something...">
            </div>
        </div>
    </div>
</body>

中的
