Question

我有一个工作搜索小部件，想要添加搜索历史记录建议。我按照Android教程（http://developer.android.com/guide/topics/search/adding-recent-query-suggestions.html），虽然搜索仍然有效，但没有显示任何建议。这是我的代码：

内容提供商

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);
    }
}

在Manifest中声明提供程序

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

可搜索的配置

<?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>

将查询保存到内容提供商（在我的可搜索活动中）

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);
}
}

一切正常，除了建议实际上没有显示（搜索看起来与我添加它们之前相同）。任何帮助将不胜感激！

我认为问题是，SearchHistoryProvider的声明在Manifest.xml中错了。

android:name=".SearchHistoryProvider"

写作。$ NAME是一个简写 $ DEFAULTPACKAGE。$ NAME，所以如果您的$ DEFAULTPACKAGE是'com.myapp' 你写的.SearchHistoryProvider作为你的android：你的名字提供商，Android根本找不到它，因为它位于 com.mypackage，如下面代码的第一行所示。

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);
    }
}

Android SearchRecentSuggestions - 在SearchView中输入时不会显示建议
