startSearch不启动搜索活动

Question

我在活动中添加了一个SearchView，并定义了一个搜索活动来处理搜索。我添加了OnQueryTextListener，并从onQueryTextSubmit()方法调用了startSearch()方法。当我将全局搜索设置为true时，它将启动谷歌搜索。当我将其设置为false时，不会发生任何事情。以下是代码：

final SearchView searchText = (SearchView) customView.findViewById(R.id.txtSearch);
     searchText.setFocusable(true);
     searchText.setIconifiedByDefault(false);
     searchText.setQueryHint(SearchActivity.this.getResources().getString(R.string.search_text_hint));
     final SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener() {
         @Override
         public boolean onQueryTextChange(String newText) {
             // Do something
             final String searchText = newText;
             if (newText.equals("")) {
                 suggestAdapter.removeAll();
                 suggestAdapter.notifyDataSetChanged();
                 return true;
             }
             if (newText.length() < 4) {
                 return true;
             }
             if (!last_onTextChanged.equals(newText))
                 onchangeHandler.removeCallbacksAndMessages(null);
             else
                 return true;
             last_onTextChanged = newText;
             onchangeHandler.postDelayed(new Runnable() {
                 @Override
                 public void run() {
                     getSearchSuggestions(searchText);
                 }
             },800);
             return true;
         }
         @Override
         public boolean onQueryTextSubmit(String query) {
             // Do something
             startSearch(query,true,null,false);
             return true;
         }
     };
     searchText.setOnQueryTextListener(queryTextListener);

以下内容在自定义操作栏布局中定义custom_search_Action_Bar.xml

    <ImageButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/abc_icon"
        android:layout_toEndOf="@+id/txtSearch"
        android:layout_marginEnd="20dp"
        android:layout_marginTop="12dp"
        android:layout_marginStart="0dp"
        android:background="@color/logo_green"
        android:layout_centerVertical="true"
        android:visibility="gone"
        android:id="@+id/ic_abc_button"/>
        <ImageButton
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/barcode_icon"
            android:layout_toEndOf="@+id/txtSearch"
            android:layout_marginEnd="20dp"
            android:layout_marginTop="5dp"
            android:layout_marginStart="0dp"
            android:background="@color/logo_green"
            android:layout_centerVertical="true"
            android:id="@+id/ic_barcode_button"/>
    </LinearLayout>
</RelativeLayout>

以下内容在res/xml/searched.xml中定义

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

最后在AndroidManifest.xml中

<activity
        android:name=".view.activity.tabsearch.SearchResultsActivity"
        android:label="@string/title_activity_search_results"
        android:parentActivityName=".view.activity.tabsearch.SearchActivity"
        android:launchMode="singleTop">
        <intent-filter>
            <action android:name="android.intent.action.SEARCH" />
        </intent-filter>
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="com.rayat.pricewiz.view.activity.tabsearch.SearchActivity" />
        <meta-data android:name="android.app.searchable"
            android:resource="@xml/searchable"/>
</activity>
    <provider android:name="com.rayat.pricewiz.provider.SearchContentProvider"
        android:authorities="com.rayat.pricewiz.provider.SearchContentProvider" />
</application>

如有任何帮助，我们将不胜感激。

您是否将MainActivity的此项放在Manifest.xml 中

        <activity android:name="MainActivity">
        <!-- enable the search dialog to send searches to SearchableActivity -->
            <meta-data android:name="android.app.default_searchable"
                android:value="SearchResultsActivity" />
        </activity>
