我正在尝试让我的应用程序只包含一个活动。这个活动应该能够创建搜索并接收搜索。不幸的是,当我点击操作栏中的搜索按钮时,我的SearchView会出现“双重”搜索栏。我的意思是,在操作栏中会出现一个黑色的搜索栏(SearchView),然后第二个白色的搜索栏会出现在操作栏上方。有什么帮助吗?我做错了什么吗? 对不起,这个搜索东西对我来说都很新和令人困惑。
MainActivity(唯一的活动):
public class MainActivity extends ActionBarActivity {
Menu mMenu;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//getSupportActionBar().setDisplayShowTitleEnabled(false);
setContentView(R.layout.activity_main);
handleIntent(getIntent());
}
@Override
protected void onNewIntent(Intent 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 your data somehow
}
}
@SuppressLint("NewApi")
@Override
public boolean onCreateOptionsMenu(Menu menu) {
mMenu = menu;
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, 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()));
searchView.setIconifiedByDefault(false);
}
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.search:
onSearchRequested();
return true;
default:
return false;
}
}
@SuppressLint("NewApi")
@Override
public boolean onSearchRequested() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
MenuItem mi = mMenu.findItem(R.id.search);
if(mi.isActionViewExpanded()){
mi.collapseActionView();
} else{
mi.expandActionView();
}
} else{
//onOptionsItemSelected(mMenu.findItem(R.id.search));
}
return super.onSearchRequested();
}
}
main.xml(菜单XML):
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:com.brianco.andypedia="http://schemas.android.com/apk/res-auto" >
<item android:id="@+id/search"

可搜索的.xml文件:

<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:label="@string/app_name"
android:hint="@string/search_hint"
android:voiceSearchMode="showVoiceSearchButton|launchRecognizer" />
在清单文件中:
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/Theme.AppCompat.Light.DarkActionBar" >
<activity
android:name="com.brianco.andypedia.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data android:name="android.app.searchable" android:resource="@xml/searchable" />
</activity>
<meta-data android:name="android.app.default_searchable"
