完成这项工作的教程.

我有两个涉及搜索的活动. SearchBar活动有操作栏,AcceptSearch是我可搜索的活动.即使我声明哪个活动是可搜索的活动,查询也不会被发送到AcceptSearch,并且活动未启动.

我配置了搜索栏,以便在窗口小部件为空时显示搜索栏提示,但提示也不会出现.这是我的代码.

搜索栏

public class SearchBar extends Activity 
{

@Override
protected void onCreate(Bundle savedInstanceState) 
{
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);

    setContentView(R.layout.search_bar);
}

@Override
public boolean onCreateOptionsMenu(Menu menu)
{
    //Inflate the options menu from XML
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.options_menu,menu);

    // Get the SearchView and set the searchable configuration
    SearchManager searchManager = (SearchManager)getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
    searchView.setIconifiedByDefault(false);        
    return true;        
}

AcceptSearch

public class AcceptSearch extends ListActivity
{
@Override
protected void onCreate(Bundle savedInstanceState) 
{       
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash_screen);

    //Get the intent,verify the action and get the query
    Intent intent = getIntent();
    if(Intent.ACTION_SEARCH.equals(intent.getAction()))
    {
        String query = intent.getStringExtra(SearchManager.QUERY);  

        //Start the search
        doMySearch();
    }
}

Searchable.xml

<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android" 
    android:label="@string/app_label"
    android:hint="@string/search_hint">    
</searchable>

options_menu

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >    
<item
    android:title="Help"
    android:id="@+id/menu_help"
    android:showAsAction="always"
/>
<item
    android:title="Categories"
    android:id="@+id/menu_cats"
    android:showAsAction="always"
/>
<item 
    android:id="@+id/menu_search"
    android:title="Search with Searchlet"
    android:icon="@drawable/ic_action_search"
    android:showAsAction="ifRoom|collapseActionView"
    android:actionViewClass="android.widget.SearchView"/>
</menu>

表现

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.searchlet"
    android:versionCode="1"
    android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="11"
    android:targetSdkVersion="15" />

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

    <activity
        android:name=".SplashScreenActivity"
        android:label="@string/title_activity_splash_screen"
        android:screenOrientation="portrait" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <activity
        android:name=".AcceptSearch">
        <intent-filter>
            <action android:name="android.intent.action.SEARCH" />
        </intent-filter>
        <Meta-data android:name="android.app.searchable"
            android:resource="@xml/searchable"/>
    </activity>

    <activity android:name=".SearchBar"
              android:label="@string/app_name">                  
        <intent-filter>
            <action android:name="com.example.searchlet.CLEARSCREEN" />
            <category android:name="android.intent.category.DEFAULT" />

        </intent-filter>
    </activity>

</application>

</manifest>

我相信所有需要的信息来重现这种情况.

谢谢大家.我很感激
