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:

        <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) {

        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);
        }

    }       
    public void doMySearch(String query) {
        Toast.makeText(getBaseContext(), query+"wsh", Toast.LENGTH_SHORT).show();
        Log.e("The query : ",query);

    }
}

这是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>

我试图让searchview小部件正常工作。如果你有任何想法我会感激。

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;
}

添加searchable.xml

此文件传统上名为 searchable.xml ,必须保存在res / xml / project目录中。

<?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>
