android内置搜索对话框（浮动搜索）例子

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

 

 <?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。

 

 <?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>

 

 

 

 

(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

 

 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）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；

 

 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);

         //打开浮动搜索框（第一个参数默认添加到搜索框的值）
         //bundle为传递的数据
         startSearch("哈哈", false, bundle, false);
         //这个地方一定要返回真 如果只是super.onSearchRequested方法
         //不但onSearchRequested（搜索框默认值）无法添加到搜索框中
         //bundle也无法传递出去
         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();
         //获得搜索框里值
         String query=intent.getStringExtra(SearchManager.QUERY);
         tvquery.setText(query);
         //保存搜索记录
         SearchRecentSuggestions suggestions=new SearchRecentSuggestions(this,
                 SearchSuggestionSampleProvider.AUTHORITY, SearchSuggestionSampleProvider.MODE);
         suggestions.saveRecentQuery(query, null);
         if(Intent.ACTION_SEARCH.equals(intent.getAction())){
             //获取传递的数据
             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);
         //获得搜索框里值
         String query=intent.getStringExtra(SearchManager.QUERY);
         tvquery.setText(query);
         //保存搜索记录
         SearchRecentSuggestions suggestions=new SearchRecentSuggestions(this,
                 SearchSuggestionSampleProvider.AUTHORITY, SearchSuggestionSampleProvider.MODE);
         suggestions.saveRecentQuery(query, null);
         if(Intent.ACTION_SEARCH.equals(intent.getAction())){
             //获取传递的数据
             Bundle bundled=intent.getBundleExtra(SearchManager.APP_DATA);
             if(bundled!=null){
                 String ttdata=bundled.getString("data");
                 tvdata.setText(ttdata);
             }else{
                 tvdata.setText("no data");
             }
         }
     }
 }
