Android SearchView小部件无法启动searchableActivity

我实际上是尝试从片段中执行搜索。我只想显示用户尝试使用SearchView小部件进行搜索的文本(使用Toast),该小部件会膨胀到片段中。根据Android文档,当用户使用SearchView小部件执行搜索时,应用程序应启动SearchableActivity。问题是我无法启动SearchableActivity。

这是我的Android Manifest(与Berhan zikarge编辑回复):

        <activity
        android:name=".ClientActivity"
        android:screenOrientation="nosensor"
        android:label="@string/title_activity_client"
        android:windowSoftInputMode="stateAlwaysHidden|adjustPan">

        <meta-data android:name="android.app.default_searchable"
            android:value=".SearchableActivity" />
        </activity>
        <activity android:name=".SearchableActivity" >
            <intent-filter>
                <action android:name="android.intent.action.SEARCH" />
            </intent-filter>
            <meta-data android:name="android.app.searchable"
                android:resource="@xml/searchable"/>
        </activity>

以下是ClientActivity中调用的片段:

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View view = inflater.inflate(R.layout.fragment_organisation_search, container, false);
        SearchView searchView = (SearchView) view.findViewById(R.id.search_view_id);
        searchView.setIconified(false);
        searchView.setIconifiedByDefault(false);
        searchView.requestFocus();
        return view;
    }

它膨胀的布局:

<ScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="match_parent"
    android:layout_width="match_parent"
    >
    <android.support.v7.widget.SearchView
        android:id="@+id/search_view_id"

        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:label="@string/app_name"
        android:hint="@string/search_hint"
        android:background="@drawable/block"
        >

    </android.support.v7.widget.SearchView>


</ScrollView>

SearchableActivity.java:

public class SearchableActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Intent intent = getIntent();
        if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
            String query = intent.getStringExtra(SearchManager.QUERY);
            doMySearch(query);
        }

    }
    //Here no log is displayed in logcat, and no Toast is shown on the app
    public void doMySearch(String query) {
        Toast.makeText(getBaseContext(), query+"wsh", Toast.LENGTH_SHORT).show();
        Log.e("The query : ",query);

    }
}

我已经纠结了这个问题超过2个小时,如果有人有解决方案,我会很感激。

修改 我把它的代码添加到我的片段中了:

@Override
public boolean onQueryTextSubmit(String query) {

    return true;
}
@Override
public boolean onQueryTextChange(String newText) {

    return false;
}

我认为您需要将元数据标记放在发送搜索数据的活动上,而不是接收数据的活动。 ClientActivity应具有元数据标记:

                                                      

<!-- this activity enables the search dialog to initiate searches
     in the SearchableActivity -->
<activity android:name=".OtherActivity" ... >
    <!-- enable the search dialog to send searches to SearchableActivity -->
    <meta-data android:name="android.app.default_searchable"
               android:value=".SearchableActivity" />
</activity>
...

问题是客户端活动的元数据不在activity标记之内。将以下代码复制并粘贴到清单

 <activity
    android:name=".ClientActivity"
    android:screenOrientation="nosensor"
    android:label="@string/title_activity_client"
    android:windowSoftInputMode="stateAlwaysHidden|adjustPan">
    <meta-data android:name="android.app.default_searchable"
        android:value=".SearchableActivity" />
    </activity>

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