Android应用开发笔记(9)：应用中调用系统的搜索UI，Android Search Framework的初步了解

经过以下几个部分的实现和配置，Android内建的搜索框架就可以在你的应用中方便使用了。

 

1 在需要显示search ui界面的activity中调用search的代码

/** Handle "search" title-bar action. */ public void onSearchClick(View v) { onSearchRequested(); } /** do the search **/ @Override public boolean onSearchRequested() { Bundle appDataBundle = new Bundle(); appDataBundle.putString("param1", "test"); startSearch("请输入搜索的关键词", true, appDataBundle, false); return true; }

 

2 创建xml/searchable.xml 对search的配置

<?xml version="1.0" encoding="utf-8"?> <!-- Copyright 2011 xxx Inc. --> <searchable xmlns:android="http://schemas.android.com/apk/res/android" android:label="@string/search_label" android:hint="@string/search_hint" <!-- Authority设置成对应provider的全称 --> android:searchSuggestAuthority="com.xxx.alimobile.util.SearchSuggestionsProvider" android:searchSuggestIntentAction="android.intent.action.SEARCH" android:searchSuggestThreshold="0" android:searchSuggestSelection=" ? " />

 

3 在AndroidManifest.xml中，给处理Search请求的页面加入intent过滤器和searchable配置文件

<activity android:name=".ui.WebViewActivity" android:theme="@style/Theme.AliMobile" android:screenOrientation="portrait" android:configChanges="orientation|keyboard|keyboardHidden"> <intent-filter> <action android:name="android.intent.action.SEARCH" /> </intent-filter> <meta-data android:name="android.app.searchable" android:resource="@xml/searchable" /> </activity>

 

4 判断是不是action_search intent事件发起的，然后处理。

if (Intent.ACTION_SEARCH.equals(intent.getAction())) { String queryString = intent.getStringExtra(SearchManager.QUERY); strUrl = "http://search1.wap.taobao.com/s/search.htm?q=" + queryString; }

 

后面还剩下suggestion的配置, 参考此篇技术文章：http://archive.cnblogs.com/a/1938752/

 

5 SearchSuggestionProvider类，继承自android.content.SearchRecentSuggestionsProvider，直接使用sdk中的简单实现。

import android.content.SearchRecentSuggestionsProvider; public class SearchSuggestionsProvider extends SearchRecentSuggestionsProvider { public final static String AUTHORITY = "com.xxx.alimobile.util.SearchSuggestionsProvider"; public final static int MODE = DATABASE_MODE_QUERIES; public SearchSuggestionsProvider() { setupSuggestions(AUTHORITY, MODE); } }

 

6 在第4步基础上加入保存功能，每次使用搜索后调用provider进行保存搜索的字段。

  if (Intent.ACTION_SEARCH.equals(intent.getAction())) { String queryString = intent.getStringExtra(SearchManager.QUERY); strUrl = "http://search1.wap.taobao.com/s/search.htm?q=" + queryString; // SAVE THE SEARCH QUERY SearchRecentSuggestions suggestions = new SearchRecentSuggestions( this, SearchSuggestionsProvider.AUTHORITY, SearchSuggestionsProvider.MODE); suggestions.saveRecentQuery(queryString, null); } else { strUrl = (String) intent.getExtras().get("goUrl"); }

 

7 AndroidManifest.xml中加入provider声明。

<provider android:name=".util.SearchSuggestionsProvider" android:authorities="com.xxx.alimobile.util.SearchSuggestionsProvider"> </provider>
