使用 MenuItemCompat (Android) 获取 SearchView [英] Getting a SearchView with MenuItemCompat (Android)

问题描述

我正在尝试按照 android 开发人员所说的那样实现 SearchView ActionBar 项，但我遇到了一些问题.(http://developer.android.com/guide/topics/ui/actionbar.html).

I am trying to implement the SearchView ActionBar item as android developers says but I am having some trouble. (http://developer.android.com/guide/topics/ui/actionbar.html).

有两个错误，虽然我找了很多，还是没能找到解决办法.

There are two mistakes that although I have looked for a lot, I have not been able to find the solution.

1) 我对 MenuItemCompat 类有问题.它说:方法 getActionView(MenuItem) 未定义为 MenuItemCompat 类型

1) I have a problem with the class MenuItemCompat. It says: The method getActionView(MenuItem) is undefined for the type MenuItemCompat

我只能为这个类使用以下方法:

I can only use for this class the following methods:

• setShowAsAction(item, actionEnum)
• setActionView(item, view)

这是代码

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.restloader, menu);
    MenuItem searchItem = menu.findItem(R.id.search_menu);
    SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);       

    // Configure the search info and add any event listeners

    return super.onCreateOptionsMenu(menu);
}

2) 这个有问题:xmlns:myapp="http://schemas.android.com/apk/res-auto"我不明白为什么使用它，但如果谷歌说它，它一定是合适的.

2) There is a problem with this: xmlns:myapp="http://schemas.android.com/apk/res-auto" I don't understand why it is used but if google says it, it must be appropriate.

错误信息:在这一行找到多个注释:- 错误:在包中找不到属性actionViewClass"的资源标识符'com.example.pruebahttp3'- 错误:在包中找不到属性showAsAction"的资源标识符'com.example.pruebahttp3'

Error message: Multiple annotations found at this line: - error: No resource identifier found for attribute 'actionViewClass' in package 'com.example.pruebahttp3' - error: No resource identifier found for attribute 'showAsAction' in package 'com.example.pruebahttp3'

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:myapp="http://schemas.android.com/apk/res-auto" >

<item
    android:id="@+id/search_menu"
    android:orderInCategory="100"
    android:title="@string/search"
    android:icon="@drawable/ic_search_category_default"
    myapp:showAsAction="ifRoom|collapseActionView"
    myapp:actionViewClass="android.support.v7.widget.SearchView">         
</item>

非常感谢！

推荐答案

我遇到了同样的问题，我使用以下代码解决了它.照顾好你的命名空间.`

i have got the same problem, i solved it by using the follow code. Be care of your namespace.`

<!-- Search, should appear as action button -->
<item
    android:id="@+id/action_search"
    android:icon="@drawable/abc_ic_search"
    share:showAsAction="ifRoom"
    share:actionViewClass="android.support.v7.widget.SearchView"
    android:title="@string/abc_searchview_description_search" />
