Question

我已经在工具栏中创建了一个简单的微调器，并在微调器后面创建了一个搜索按钮，如所有我需要的单击搜索按钮用编辑文本替换微调器我可以搜索项目顺便说一下，如果我点击旋转器中的项目，它会显示另一个项目来自数据库这是我的xml，它有工具栏

这是具有工具栏组件的menu.xml，其中包含搜索按钮

<?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">

    <item android:id="@+id/searchicon"
        android:icon="@drawable/search"
        android:title="@string/search"
        app:showAsAction="always"/>

    <item android:id="@+id/listicon"
        android:icon="@drawable/list_view"
        android:title="@string/listview"
        app:showAsAction="always"/>

    <item android:id="@+id/gridicon"
        android:icon="@drawable/table_grid"
        android:title="@string/gridview"
        app:showAsAction="always"/>
</menu>

这是工具bar.xml的活动
