Android SearchRecentSuggestions - 在輸入時不會顯示建議SearchView

Question

我有一個可用的搜索小部件，並希望添加搜索歷史記錄建議。我遵循Android教程（http://developer.android.com/guide/topics/search/adding-recent-query-suggestions.html），雖然搜索仍然有效，但沒有任何建議正在顯示。這裏是我的代碼：

1. 內容提供商

   package com.mypackage; 
   
   import android.content.SearchRecentSuggestionsProvider; 
   
   public class SearchHistoryProvider extends SearchRecentSuggestionsProvider { 
       public final static String AUTHORITY = SearchHistoryProvider.class.getName(); 
       public final static int MODE = DATABASE_MODE_QUERIES; 
   
       public SearchHistoryProvider() { 
        setupSuggestions(AUTHORITY, MODE); 
       } 
   } 
   

2. 在清單

   <provider 
       android:name=".SearchHistoryProvider" 
       android:authorities="com.mypackage.SearchHistoryProvider"> 
   </provider> 
   

3. 檢索配置

   <?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" 
       android:voiceSearchMode="showVoiceSearchButton|launchRecognizer" 
       android:searchSuggestAuthority="com.mypackage.SearchHistoryProvider" 
       android:searchSuggestSelection=" ?"> 
   </searchable> 
   

4. 聲明提供商保存查詢到內容提供商（在我搜索的Activity）

   private void handleIntent(Intent intent) { 
   if (Intent.ACTION_SEARCH.equals(intent.getAction())) { 
   
       String query = intent.getStringExtra(SearchManager.QUERY); 
       SearchRecentSuggestions suggestions = new SearchRecentSuggestions(this, 
            SearchHistoryProvider.AUTHORITY, SearchHistoryProvider.MODE); 
       suggestions.saveRecentQuery(query, null); 
   
       // Collapse the search view as a search is performed 
       MenuItem searchItem = mMenu.findItem(R.id.search); 
       SearchView searchView = (SearchView) mMenu.findItem(R.id.search).getActionView(); 
       searchItem.collapseActionView(); 
       searchView.setQuery("", false); 
   
       // send the query to the global search activity for loading the data 
       Intent globalSearchIntent = new Intent(this, GlobalSearchFragmentActivity.class); 
       GroceryOTGUtils.copyIntentData(intent, globalSearchIntent); 
       globalSearchIntent.putExtra(GlobalSearchFragmentActivity.GLOBAL_SEARCH, true); 
       startActivity(globalSearchIntent); 
   } 
   } 
   

一切工作正常，但建議不實際顯示（搜索看上去和以前一樣我加入他們）。任何幫助將不勝感激！

我認爲問題是，Manifest.xml中SearchHistoryProvider 的聲明是錯誤的。

android:name=".SearchHistoryProvider" 

寫作$ NAME是 $ DEFAULTPACKAGE速記$ NAME，所以如果你的$ DEFAULTPACKAGE是 'com.myapp' UND你寫.SearchHistoryProvider由於Android：。你 提供商的名稱，Android的將無法找到它，因爲它位於 com.mypackage中，如以下代碼的第一行所示。

package com.mypackage; 

import android.content.SearchRecentSuggestionsProvider; 

public class SearchHistoryProvider extends SearchRecentSuggestionsProvider { 
    public final static String AUTHORITY = SearchHistoryProvider.class.getName(); 
    public final static int MODE = DATABASE_MODE_QUERIES; 

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