Android SearchRecentSuggestions - 在SearchView中输入时不会显示建议 [英] Android SearchRecentSuggestions - suggestions do not get displayed when typing in SearchView

问题描述

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/主题/ search / adding-recent-query-suggestions.html ），虽然搜索仍然有效，但不会显示任何建议。这是我的代码：

I have a working search widget and want to add search history suggestions. I followed the Android tutorial (http://developer.android.com/guide/topics/search/adding-recent-query-suggestions.html), and while the search still works, no suggestions are being displayed. Here is my code:

1. 内容提供商

1. Content provider

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);
    }
}

在清单中声明提供程序

Declaring provider in Manifest

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

可搜索的配置

Searchable configuration

<?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）

Saving the queries to the content provider (in my searchable 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);
}
}

一切正常，除了建议实际上没有显示（搜索看起来和我添加它们之前一样）。任何帮助将不胜感激！

Everything works fine, except the suggestions do not actually show up (the search looks the same as before I added them). Any help would be greatly appreciated!

推荐答案

我认为问题在于，SearchHistoryProvider
的声明在Manifest.xml错了。

I think the problem was, that the declaration of the SearchHistoryProvider in the Manifest.xml was wrong.

android:name=".SearchHistoryProvider"

写作。$ NAME是
$ DEFAULTPACKAGE。$ NAME的简写，所以如果你的$ DEFAULTPACKAGE是'com.myapp'
und你写的.SearchHistoryProvider as你的
提供者的android：名称，Android根本找不到它，因为它位于
com.mypackage中，因为以下代码的第一行表示。

Writing .$NAME is a shorthand for $DEFAULTPACKAGE.$NAME, so if your $DEFAULTPACKAGE is 'com.myapp' und you write .SearchHistoryProvider as the android:name of your Provider, Android will simply not find it, as it is located in com.mypackage, as the first line of the following code indicates.

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);
    }
}
