最近的搜索未显示

Question

我正在使用Wiki API在recyclerView中显示搜索。我有一个搜索栏，我想在用户键入任何查询时显示最近的搜索。我已经创建了提供程序类，还实现了handleIntent（）并在main方法中对其进行了调用。

MainActivity：

    @Override
        public boolean onCreateOptionsMenu(Menu menu) {
            getMenuInflater().inflate(R.menu.search_text_item,menu);
            SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
            final MenuItem searchItem = menu.findItem(R.id.action_search);
            final SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);

            //final SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
            searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
            searchView.setIconifiedByDefault(false); // Do not iconify the widget;

            searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
                @Override
                public boolean onQueryTextSubmit(String query) {
                    fetchPages(query);
                    // Reset SearchView
                    searchView.clearFocus();
                    searchView.setQuery("", false);
                    searchView.setIconified(true);
                    searchItem.collapseActionView();
                    return true;
                }

                @Override
                public boolean onQueryTextChange(String newText) {


                    return true;
                }
            });

            return true;
        }
@Override
    protected void onNewIntent(Intent intent) {
        handleIntent(intent);
    }
    private void handleIntent(Intent intent) {

        //store the search and display it
        if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
            //get search query
            searchQuery = intent.getStringExtra(SearchManager.QUERY);

            //save search
            SearchRecentSuggestions suggestions = new SearchRecentSuggestions(this,
                    MySuggestionProvider.AUTHORITY, MySuggestionProvider.MODE);
            suggestions.saveRecentQuery(searchQuery, null);


            //set search to the textview
            //mTextView.setText(searchQuery);

        } else if (Intent.ACTION_VIEW.equals(intent.getAction())) {
            // Handle a suggestions click (because the suggestions all use ACTION_VIEW)
            searchQuery = intent.getStringExtra(SearchManager.QUERY);

            //set search term to the textview
           // mTextView.setText(searchQuery);
        }
    }

提供者：

public class MySuggestionProvider extends SearchRecentSuggestionsProvider {
    public final static String AUTHORITY = "wiki.com.wikisearch.contentProvider.MySuggestionProvider";
    public final static int MODE = DATABASE_MODE_QUERIES| DATABASE_MODE_2LINES;

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

清单：

 <activity android:name=".MainActivity">

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

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

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
            <meta-data
                android:name="android.app.searchable"
                android:resource="@xml/searchable" />
        </activity>
        <activity android:name=".WbViewActivity"/>
        <provider
            android:authorities="wiki.com.wikisearch.contentProvider.MySuggestionProvider"

            android:name=".contentProvider.MySuggestionProvider"/>

我不明白为什么在搜索栏中键入内容时没有得到任何建议，我错过了什么吗？
