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");
}
}
}
}
