差点忘了，先上图看效果吧：
步骤：
（1）配置search bar的相关信息，新建一个位于res/xml下的一个searchable.xml的配置文件
1<?xml version="1.0" encoding="utf-8"?> 2<searchable 3 xmlns:android="http://schemas.android.com/apk/res/android" 4 android:hint="@string/searchHint" 5 android:searchMode="showSearchLabelAsBadge" 6 android:searchSuggestAuthority="com.android.cbin.SearchSuggestionSampleProvider" 7 android:searchSuggestSelection=" ? "> 8 9</searchable>
（2） manifest.xml配置，搜索结果处理的Activity将出现两种情况，一种是从其他Activity中的search bar打开一个Activtiy
专门处理搜索结果，第二种是就在当前Activity就是处理结果的Activity，这配置里包含两种情况，自己可以看代码能分辨出来。
1<?xml version="1.0" encoding="utf-8"?> 2<manifest xmlns:android="http://schemas.android.com/apk/res/android" 3 package="com.android.cbin" 4 android:versionCode="1" 5 android:versionName="1.0"> 6 <application android:icon="@drawable/icon" android:label="@string/app_name"> 7 <activity android:name=".Main" 8 android:label="@string/app_name"> 9 <intent-filter> 10 <action android:name="android.intent.action.MAIN" /> 11 <category android:name="android.intent.category.LAUNCHER" /> 12 </intent-filter> 13 14 <meta-data android:name="android.app.default_searchable" 15 android:value=".SearchResultActivity" /> 16 </activity> 17 <activity android:name="SearchResultActivity" android:launchMode="singleTop"> 18 19 <intent-filter> 20 <action android:name="android.intent.action.SEARCH"></action> 21 </intent-filter> 22 <meta-data android:resource="@xml/searchable" android:name="android.app.searchable"></meta-data> 23 </activity> 24<provider android:name="SearchSuggestionSampleProvider" android:authorities="com.android.cbin.SearchSuggestionSampleProvider"></provider> 25</application> 26 <uses-sdk android:minSdkVersion="7" /> 27</manifest>
(3 ) 保存历史记录
上面authorities 指向的 都是name中所关联的SearchSuggestionSampleProvider，他是一个
SearchRecentSuggestionsProvider的子类
1package com.android.search; 2import android.content.SearchRecentSuggestionsProvider; 3public class SearchSuggestionSampleProvider extends 4 SearchRecentSuggestionsProvider { 5 final static String AUTHORITY="com.android.search.SearchSuggestionSampleProvider"; 6 final static int MODE=DATABASE_MODE_QUERIES; 7 8 public SearchSuggestionSampleProvider(){ 9 super(); 10 setupSuggestions(AUTHORITY, MODE); 11 } 12}
（4）为了能够使用search bar 我们必须重写Activity的onSearchRequested的方法，在界面上启动一个search bar
但是这个动作不会自动触发，必须通过一个按钮或者菜单的点击事件触发；
1package com.android.search; 2import com.android.search.R; 3import android.app.Activity; 4import android.os.Bundle; 5import android.view.View; 6import android.view.View.OnClickListener; 7import android.widget.Button; 8import android.widget.EditText; 9public class Main extends Activity implements OnClickListener{ 10 /** Called when the activity is first created. */ 11 private EditText etdata; 12 private Button btnsearch; 13 @Override 14 public void onCreate(Bundle savedInstanceState) { 15 super.onCreate(savedInstanceState); 16 setContentView(R.layout.main); 17 18 findview(); 19 } 20 21 private void findview(){ 22 etdata=(EditText)findViewById(R.id.etdata); 23 btnsearch=(Button)findViewById(R.id.btncall); 24 btnsearch.setOnClickListener(this); 25 } 26 @Override 27 public void onClick(View v) { 28 // TODO Auto-generated method stub 29 onSearchRequested(); 30 } 31 32 @Override 33 public boolean onSearchRequested(){ 34 35 String text=etdata.getText().toString(); 36 Bundle bundle=new Bundle(); 37 bundle.putString("data", text); 38 39 //打开浮动搜索框（第一个参数默认添加到搜索框的值） 40 //bundle为传递的数据 41 startSearch("哈哈", false, bundle, false); 42 //这个地方一定要返回真 如果只是super.onSearchRequested方法 43 //不但onSearchRequested（搜索框默认值）无法添加到搜索框中 44 //bundle也无法传递出去 45 return true; 46 } 47 48}
（5） 在本Activity中搜索
1package com.android.search; 2import com.android.search.R; 3import android.app.Activity; 4import android.app.SearchManager; 5import android.content.Intent; 6import android.os.Bundle; 7import android.provider.SearchRecentSuggestions; 8import android.view.View; 9import android.view.View.OnClickListener; 10import android.widget.Button; 11import android.widget.TextView; 12public class SearchResultActivity extends Activity implements OnClickListener{ 13 private TextView tvquery,tvdata; 14 private Button btnsearch; 15 @Override 16 protected void onCreate(Bundle savedInstanceState){ 17 super.onCreate(savedInstanceState); 18 setContentView(R.layout.searchresult); 19 20 tvquery=(TextView)findViewById(R.id.tvquery); 21 tvdata=(TextView)findViewById(R.id.tvdata); 22 btnsearch=(Button)findViewById(R.id.btnSearch); 23 doSearchQuery(); 24 25 btnsearch.setOnClickListener(this); 26 } 27 28 public void doSearchQuery(){ 29 final Intent intent = getIntent(); 30 //获得搜索框里值 31 String query=intent.getStringExtra(SearchManager.QUERY); 32 tvquery.setText(query); 33 //保存搜索记录 34 SearchRecentSuggestions suggestions=new SearchRecentSuggestions(this, 35 SearchSuggestionSampleProvider.AUTHORITY, SearchSuggestionSampleProvider.MODE); 36 suggestions.saveRecentQuery(query, null); 37 if(Intent.ACTION_SEARCH.equals(intent.getAction())){ 38 //获取传递的数据 39 Bundle bundled=intent.getBundleExtra(SearchManager.APP_DATA); 40 if(bundled!=null){ 41 String ttdata=bundled.getString("data"); 42 tvdata.setText(ttdata); 43 }else{ 44 tvdata.setText("no data"); 45 } 46 } 47 } 48 @Override 49 public void onClick(View v) { 50 // TODO Auto-generated method stub 51 onSearchRequested(); 52 } 53 54 @Override 55 public boolean onSearchRequested(){ 56 57 startSearch("onNewIntent", false, null, false); 58 return true; 59 } 60 61 @Override 62 public void onNewIntent(Intent intent){ 63 super.onNewIntent(intent); 64 //获得搜索框里值 65 String query=intent.getStringExtra(SearchManager.QUERY); 66 tvquery.setText(query); 67 //保存搜索记录 68 SearchRecentSuggestions suggestions=new SearchRecentSuggestions(this, 69 SearchSuggestionSampleProvider.AUTHORITY, SearchSuggestionSampleProvider.MODE); 70 suggestions.saveRecentQuery(query, null); 71 if(Intent.ACTION_SEARCH.equals(intent.getAction())){ 72 //获取传递的数据 73 Bundle bundled=intent.getBundleExtra(SearchManager.APP_DATA); 74 if(bundled!=null){ 75 String ttdata=bundled.getString("data"); 76 tvdata.setText(ttdata); 77 }else{ 78 tvdata.setText("no data"); 79 } 80 } 81 } 82}
