这些是我正在使用的步骤

 Searchable xml file 

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




Provider 


        <provider android:name=".MySuggestionProvider"
            android:authorities="example.com.cle.MySuggestionProvider" />


Activity in manifiest

 <activity
            android:name=".BaseActivity"
            android:configChanges="orientation|screenSize|keyboardHidden"
            android:theme="@style/AppTheme.ActionBar">


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


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


Activity class

  protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        Intent intent = getIntent();

        if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
            String query = intent.getStringExtra(SearchManager.QUERY);
            SearchRecentSuggestions suggestions = new SearchRecentSuggestions(this,
                    MySuggestionProvider.AUTHORITY, MySuggestionProvider.MODE);
            suggestions.saveRecentQuery(query, null);


        }
    }


Content provider class 

public final static String AUTHORITY ="example.com.cle.MySuggestionProvider";
    public final static int MODE = DATABASE_MODE_QUERIES;

    public MySuggestionProvider() {
        setupSuggestions(AUTHORITY, MODE);
    }

我找到了解决办法

1.创建可搜索的xml文件夹

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

2.创建内容提供者类扩展 SearchRecentSuggestionsProvider

 public class MySuggestionProvider extends SearchRecentSuggestionsProvider {

    public final static String AUTHORITY = "your package name.MySuggestionProvider";
    public final static int MODE = DATABASE_MODE_QUERIES;

    public MySuggestionProvider() {
        setupSuggestions(AUTHORITY, MODE);
    }
}

在你的活动课中

oncreate 方法

 handledearch(getIntent());

4. over ride method


    @Override
    protected void onNewIntent(Intent intent) {
       setIntent(intent);

      handledearch(intent);
    }

    public void handledearch( Intent intent)
    {
        if (Intent.ACTION_SEARCH.equalsIgnoreCase(intent.getAction())) {
            String query = intent.getStringExtra(SearchManager.QUERY);

        mtToolbar.setTitle(query);

            SearchRecentSuggestions searchRecentSuggestions=new SearchRecentSuggestions(this,
                    MySuggestionProvider.AUTHORITY,MySuggestionProvider.MODE);

            searchRecentSuggestions.saveRecentQuery(query,null);
        }
    }

在菜单中

@覆盖 public boolean onCreateOptionsMenu(Menu menu) {

    getMenuInflater().inflate(R.menu.menu,menu);

    SearchManager searchManager=(SearchManager)getSystemService(Context.SEARCH_SERVICE);

    SearchView searchView;

    MenuItem menuItem=menu.findItem(R.id.action_search);

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)
    {
        searchView=(SearchView)menuItem.getActionView();

    }
    else
    {
        searchView=(SearchView) MenuItemCompat.getActionView(menuItem);

    }

    searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
    searchView.setQueryHint(getResources().getString(R.string.search_hint));

    return super.onCreateOptionsMenu(menu);

}
