java - SearchView 不启动 SearchableActivity

Question

我想添加 SearchView给我的ActionBar ，所以我按照 Google 教程中报告的那样做了 here .

AndroidManifest.xml

<activity
        android:name="it.polimi.dima.sound4u.activity.SoundSearchActivity"
        android:label="@string/title_activity_sound_search" >
        <intent-filter>
            <action android:name="android.intent.action.SEARCH" />
        </intent-filter>
    </activity>
    <activity
        android:name="it.polimi.dima.sound4u.activity.MyGiftsActivity"
        android:label="@string/title_activity_my_gifts" >
        <meta-data android:name="android.app.searchable"
                   android:resource="@xml/searchable" />
    </activity>

searchable.xml

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

MyGiftsActivity.java

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.my_gifts, menu);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
        SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        SearchView searchView = (SearchView) menu.findItem(R.id.search).getActionView();
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
    }
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.search:
            onSearchRequested();
            return true;
        case R.id.action_logout:
            doLogout();
            return true;
        case R.id.action_settings:
            return true;
    }
    return super.onOptionsItemSelected(item);
}

my_gifts.xml

<?xml version="1.0" encoding="utf-8"?>

<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto">

    <item android:id="@+id/search"
          android:title="@string/search_title"
          android:icon="@drawable/ic_action_search"
          android:showAsAction="collapseActionView|ifRoom"
          android:actionViewClass="android.widget.SearchView" />


    <item android:id="@+id/action_logout"
          android:title="@string/logout_label"
          android:showAsAction="ifRoom" />

    <item android:id="@+id/action_settings"
          android:title="@string/action_settings"
          android:orderInCategory="100"
          app:showAsAction="never" />
</menu>

SoundSearchActivity.java

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_sound_search);
    handleIntent(getIntent());
}

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    handleIntent(intent);
}

private void handleIntent(Intent intent) {
    if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
        String query = intent.getStringExtra(SearchManager.QUERY);
        Log.w(TAG_LOG, query);
    }
}

SearchView已正确创建并可以从 Icon 切换模式为TextView模式，但是当我按下 Search Button 时键盘上的新SoundSearchActivity不启动。有人可以帮助我吗？

在 list 中尝试此操作:

• 在启动搜索的 Activity 标记中添加指向 SearchActivity 的元数据
• 将可搜索标签移至 SearchAvtivity

• 将 launchMode="singleTop"添加到 SearchActivity 以确保堆栈顶部只有一个实例。新的搜索 Intent 将通过您已经实现的 onNewIntent 出现。

          <meta-data android:name="android.app.searchable"
                     android:resource="@xml/searchable" />
      </activity>
      <activity
          android:name="it.polimi.dima.sound4u.activity.MyGiftsActivity"
          android:label="@string/title_activity_my_gifts" >
  
          <meta-data android:name="android.app.default_searchable"
                     android:value="it.polimi.dima.sound4u.activity.SoundSearchActivity"/>
  

Google 的初始指南(找到 here )也没有给我一个有效的 SearchView，但进行这些更改却给了我一个有效的 SearchView。
