<activity
  android:name=".navigation.NavigationActivity"
  android:label="@string/title_activity_navigation">
  <intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.DEFAULT" />
  </intent-filter>
  <meta-data
    android:name="android.app.default_searchable"
    android:value=".search.SearchResultActivity" />
</activity>

2. 在提供搜索結(jié)果的Activity中添加為SearchableInfo用的meta-data

<activity
  android:name=".search.SearchResultActivity"
  android:label="@string/title_activity_search_result"
  android:launchMode="singleTop">
  <intent-filter>
    <action android:name="android.intent.action.SEARCH" />
  </intent-filter>
   <!--This metadata entry provides further configuration details for searches-->
   <!--that are handled by this activity.-->
  <meta-data
    android:name="android.app.searchable"
    android:resource="@xml/searchable" />
</activity>

3. @xml/searchable文件中的Android:hint只能使用string.xml中定義的字符串，不能hard-coded

<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
  android:label="@string/app_name"
  android:hint="@string/search_hint">
</searchable>

4. 初始化Menu的時(shí)候，獲取SearchableInfo

SearchManager searchManager = (SearchManager)getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView)menu.findItem(R.id.action_search).getActionView();
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));

注意點(diǎn)

SearchManager通過(guò)ComponentName查找SearchableInfo的時(shí)候，對(duì)應(yīng)Component必須滿足一定條件：

1. intent-filter包含

<action android:name="android.intent.action.SEARCH" />

2. meta-data

<meta-data
  android:name="android.app.searchable"
  android:resource="@xml/searchable" />

另一種方法

既然SearchManager是通過(guò)ComponentName來(lái)獲取SearchableInfo，當(dāng)然可以直接從提供搜索結(jié)果的Activity中獲取ComponentName。

SearchManager searchManager = (SearchManager)getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView)menu.findItem(R.id.action_search).getActionView();
ComponentName cn = new ComponentName("com.liangfeizc.catykanji", "com.liangfeizc.catykanji.search.SearchResultActivity");
searchView.setSearchableInfo(searchManager.getSearchableInfo(cn));

tips

ComponentName構(gòu)造函數(shù)的第一個(gè)參數(shù)pkg是Application的Package，不是目標(biāo)類所在的Package。

The first parameter ComponentName(String pkg, String cls) is application package not the package where the activity is.
