我想实现我在操作栏使用搜索栏小工具Android应用搜索。

I'm trying to implement a search on my android application using a search bar widget in the action bar.

我下面

http://developer.android.com/guide/topics/search/search-dialog.html http://developer.android.com/guide/topics/ui/actionbar.html#ActionView

要完成这件事的教程。

我参与搜索的两项活动。搜索栏活动有操作栏和AcceptSearch是我的搜索活动。即使我宣布该活动是搜索的活动，查询不被发送到AcceptSearch和活动没有启动。

I have two activities involved in searching. SearchBar activity has the action bar and AcceptSearch is my searchable activity. Even though I declared which activity was the searchable activity, the query is not being sent over to AcceptSearch and the activity is not launched.

我配置，使得当构件是空的，但暗示永远不会出现任何一个搜索栏提示显示的搜索栏。这是我的code。

I configured the search bar such that a search bar hint appears when the widget is empty, but the hint never appears either. Here is my code.

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>

清单

    <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beleive这就是所有必要的信息，以重现这种情况。

I beleive thats all the needed information to recreate the situation.

感谢大家提前。我AP precicate。

Thank you all in advance. I apprecicate.

推荐答案

我也有类似的问题。我在下面的 grokking的教程并从未打开过的活动。我试过Indrek的解决方案，我对我的作品。

I had a similar problem. I was following grokking's tutorial and the activity never opened. I tried the Indrek's solutions I that works for me.

您应该确保您有在合适的父权的元数据。元数据

You should be sure that you have the right meta-data under the right parent. The meta-data

<meta-data
     android:name="android.app.default_searchable"
     android:value=".NameSearchActivity" />

应该是在应用程序。后续的元数据。

should be under application. The follow meta-data

<meta-data
     android:name="android.app.searchable"
     android:resource="@xml/searchable" />

应该是里面AndroidManifest.xml中搜索活动的参数下。

should be under the search activity parameter inside AndroidManifest.xml.

在搜索活动我没有什么好说的，用于管理活动的叠前挂的教程。我希望这个解决方案适用于每个人同样的问题。

In the search Activity I did what it say in the tutorial linked before for managing the activity stack. I hope that this solution works for everyone with the same problem.
