我已经找到了解决方案。甚至两个解决方案!
他们不需要调用onSearchRequested(),因此根本没有搜索对话框:)
首先,我提供了一些创建搜索界面的常用步骤,然后给出了源问题的解决方案。
我们通过使用以下代码创建res/menu/options_menu.xml 文件将搜索视图添加到应用栏:
<?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"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainActivity" >
<item
android:id="@+id/action_search"
android:icon="@drawable/ic_action_search"
android:title="@string/search_string"
app:showAsAction="collapseActionView|ifRoom"
app:actionViewClass="android.support.v7.widget.SearchView" />
</menu>
在res/xml/searchable.xml 文件中创建可搜索配置:
<?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" />
在AndroidManifest.xml中声明两个活动:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.searchinterface">
<application
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme">
<activity
android:name=".MainActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".SearchableActivity"
android:label="@string/app_name"
android:launchMode="singleTop">
<intent-filter>
<action android:name="android.intent.action.SEARCH"/>
</intent-filter>
<meta-data android:name="android.app.searchable"
android:resource="@xml/searchable"/>
</activity>
</application>
</manifest>
创建一个 Searchable Activity,我们在其中处理 ACTION_SEARCH 意图和从 MainActivity 传递的搜索上下文数据。我们从APP_DATABundle 中提取额外的数据来优化搜索:
public class SearchableActivity extends AppCompatActivity {
public static final String JARGON = "com.example.searchinterface.jargon";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_searchable);
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);
// use the query to search the data somehow
Bundle appData = intent.getBundleExtra(SearchManager.APP_DATA);
if (appData != null) {
boolean jargon = appData.getBoolean(SearchableActivity.JARGON);
// use the context data to refine our search
}
}
}
}
现在,我们需要实现 MainActivity 类。因此,我们膨胀我们的菜单并配置SearchView 元素。我们还需要设置SearchView.OnQueryTextListener 并实现它的方法,尤其是onQueryTextSubmit()。当用户按下提交按钮时调用它,它包含将搜索上下文数据传递给SearchableActivity 的主要逻辑。
最后,我们到达了主要答案部分。正如我所说,有两种解决方案:
1.使用额外的Bundle 创建一个意图并将其手动发送到SearchableActivity;
这里是MainActivity 的所有必要内容:
public class MainActivity extends AppCompatActivity implements SearchView.OnQueryTextListener {
private SearchView mSearchView;
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.options_menu, menu);
MenuItem searchItem = menu.findItem(R.id.action_search);
mSearchView = (SearchView) MenuItemCompat.getActionView(searchItem);
// associate searchable configuration with the SearchView
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
mSearchView.setSearchableInfo(searchManager.getSearchableInfo(
new ComponentName(this, SearchableActivity.class)));
mSearchView.setOnQueryTextListener(this);
return true;
}
@Override
public boolean onQueryTextSubmit(String query) {
Intent searchIntent = new Intent(this, SearchableActivity.class);
searchIntent.putExtra(SearchManager.QUERY, query);
Bundle appData = new Bundle();
appData.putBoolean(SearchableActivity.JARGON, true); // put extra data to Bundle
searchIntent.putExtra(SearchManager.APP_DATA, appData); // pass the search context data
searchIntent.setAction(Intent.ACTION_SEARCH);
startActivity(searchIntent);
return true; // we start the search activity manually
}
@Override
public boolean onQueryTextChange(String newText) {
return false;
}
}

第二个解决方案也放入onQueryTextSubmit()(但不是必须的):
2。创建搜索上下文数据Bundle 并将其传递给SearchView 的setAppSearchData() 方法。
因此,我们不需要创建和传递整个搜索意图并启动相应的可搜索活动,系统会处理它。
这是另一个代码sn-p:
/*
You may need to suppress the “restrictedApi” error that you could possibly
receive from this method "setAppSearchData(appData)”.I had to
I’m targetSdkVersion 26. I’m also using Android Studio 3
with the new gradle plugin, which might be causing this.
If you’re not running Android Studio 3 you can simply put
“//noinspection RestrictedApi"
right above the line: mSearchView.setAppSearchData(appData);
*/
@SuppressWarnings("RestrictedApi")
@Override
public boolean onQueryTextSubmit(String query) {
Bundle appData = new Bundle();
appData.putBoolean(SearchableActivity.JARGON, true); // put extra data to Bundle
mSearchView.setAppSearchData(appData); // pass the search context data
return false; // we do not need to start the search activity manually, the system does it for us
}

注意:只支持库版本的SearchView(android.support.v7.widget.SearchView)包含setAppSearchData()方法,请注意。
