This example describes the use of Android Actionbar search functionality. Share to everyone for your reference, specific as follows:

Points to note when using Actionbar Searchview:

The first thing to do is to spit out the official guide documentation for Android, which is unclear about usage and may be why it hasn't been updated.

Originally according to the document, hint not come out, also can't jump to search results activity.

StackOverflow also someone raised the question, the answer is very clear-reference links.

Correct usage

1. Add Meta-data to the activity in androidmanifest.xml for the provision of Searchview

<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. Add Meta-data to Searchableinfo in activity that provides search results

<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. The android:hint in the @xml/searchable file can only use strings defined in String.xml, not 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. When the menu is initialized, get Searchableinfo

Searchmanager Searchmanager = (searchmanager) getsystemservice (context.search_service);
Searchview Searchview = (searchview) menu.finditem (r.id.action_search). Getactionview ();
Searchview.setsearchableinfo (Searchmanager.getsearchableinfo (Getcomponentname ()));

Pay attention.

Searchmanager through ComponentName to find Searchableinfo, the corresponding component must meet certain conditions:

1. Intent-filter contains

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

2. Meta-data

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

Another way

Since Searchmanager is componentname to get searchableinfo, of course, you can get componentname directly from the activity that provides the search results.

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

The first parameter of the ComponentName constructor pkg is the package of the application, not the package where the target class resides.

The parameter componentname (string pkg, string cls) is application package not the package where the
