差點忘了，先上圖看效果吧：

步驟：

（1）配置search bar的相關信息，新建一個位于res/xml下的一個searchable.xml的配置文件

<?xml version="1.0" encoding="utf-8"?> <searchable xmlns:android="http://schemas.android.com/apk/res/android" android:hint="@string/searchHint" android:searchMode="showSearchLabelAsBadge" android:searchSuggestAuthority="com.android.cbin.SearchSuggestionSampleProvider" android:searchSuggestSelection=" ? "> </searchable>

（2）manifest.xml配置，搜索結果處理的Activity將出現兩種情況，一種是從其他Activity中的search bar打開一個Activtiy

專門處理搜索結果，第二種是就在當前Activity就是處理結果的Activity，這配置里包含兩種情況，自己可以看代碼能分辨出來。

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.android.cbin" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".Main" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> <meta-data android:name="android.app.default_searchable" android:value=".SearchResultActivity" /> </activity> <activity android:name="SearchResultActivity" android:launchMode="singleTop"> <intent-filter> <action android:name="android.intent.action.SEARCH"></action> </intent-filter> <meta-data android:resource="@xml/searchable" android:name="android.app.searchable"></meta-data> </activity> <provider android:name="SearchSuggestionSampleProvider" android:authorities="com.android.cbin.SearchSuggestionSampleProvider"></provider> </application> <uses-sdk android:minSdkVersion="7" /> </manifest>

package com.android.search; import android.content.SearchRecentSuggestionsProvider; public class SearchSuggestionSampleProvider extends SearchRecentSuggestionsProvider { final static String AUTHORITY="com.android.search.SearchSuggestionSampleProvider"; final static int MODE=DATABASE_MODE_QUERIES; public SearchSuggestionSampleProvider(){ super(); setupSuggestions(AUTHORITY, MODE); } }

（4）為了能夠使用search bar 我們必須重寫Activity的onSearchRequested的方法，在界面上啟動一個search bar

但是這個動作不會自動觸發，必須通過一個按鈕或者菜單的點擊事件觸發；

package com.android.search; import com.android.search.R; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.EditText; public class Main extends Activity implements OnClickListener{ /** Called when the activity is first created. */ private EditText etdata; private Button btnsearch; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); findview(); } private void findview(){ etdata=(EditText)findViewById(R.id.etdata); btnsearch=(Button)findViewById(R.id.btncall); btnsearch.setOnClickListener(this); } @Override public void onClick(View v) { // TODO Auto-generated method stub onSearchRequested(); } @Override public boolean onSearchRequested(){ String text=etdata.getText().toString(); Bundle bundle=new Bundle(); bundle.putString("data", text); //打開浮動搜索框（第一個參數默認添加到搜索框的值） //bundle為傳遞的數據 startSearch("哈哈", false, bundle, false); //這個地方一定要返回真 如果只是super.onSearchRequested方法 //不但onSearchRequested（搜索框默認值）無法添加到搜索框中 //bundle也無法傳遞出去 return true; } }

（5） 在本Activity中搜索

package com.android.search; import com.android.search.R; import android.app.Activity; import android.app.SearchManager; import android.content.Intent; import android.os.Bundle; import android.provider.SearchRecentSuggestions; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.TextView; public class SearchResultActivity extends Activity implements OnClickListener{ private TextView tvquery,tvdata; private Button btnsearch; @Override protected void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.searchresult); tvquery=(TextView)findViewById(R.id.tvquery); tvdata=(TextView)findViewById(R.id.tvdata); btnsearch=(Button)findViewById(R.id.btnSearch); doSearchQuery(); btnsearch.setOnClickListener(this); } public void doSearchQuery(){ final Intent intent = getIntent(); //獲得搜索框里值 String query=intent.getStringExtra(SearchManager.QUERY); tvquery.setText(query); //保存搜索記錄 SearchRecentSuggestions suggestions=new SearchRecentSuggestions(this, SearchSuggestionSampleProvider.AUTHORITY, SearchSuggestionSampleProvider.MODE); suggestions.saveRecentQuery(query, null); if(Intent.ACTION_SEARCH.equals(intent.getAction())){ //獲取傳遞的數據 Bundle bundled=intent.getBundleExtra(SearchManager.APP_DATA); if(bundled!=null){ String ttdata=bundled.getString("data"); tvdata.setText(ttdata); }else{ tvdata.setText("no data"); } } } @Override public void onClick(View v) { // TODO Auto-generated method stub onSearchRequested(); } @Override public boolean onSearchRequested(){ startSearch("onNewIntent", false, null, false); return true; } @Override public void onNewIntent(Intent intent){ super.onNewIntent(intent); //獲得搜索框里值 String query=intent.getStringExtra(SearchManager.QUERY); tvquery.setText(query); //保存搜索記錄 SearchRecentSuggestions suggestions=new SearchRecentSuggestions(this, SearchSuggestionSampleProvider.AUTHORITY, SearchSuggestionSampleProvider.MODE); suggestions.saveRecentQuery(query, null); if(Intent.ACTION_SEARCH.equals(intent.getAction())){ //獲取傳遞的數據 Bundle bundled=intent.getBundleExtra(SearchManager.APP_DATA); if(bundled!=null){ String ttdata=bundled.getString("data"); tvdata.setText(ttdata); }else{ tvdata.setText("no data"); } } } }
