问题
I'm developing search widget interface based on official tutorial: http://developer.android.com/guide/topics/search/search-dialog.html
Problem: My SearchableActivity doesn't get triggered when I enter my query and press Ok/enter.
Manifest for SearchableActivity:
<activity android:name="SearchableActivity" 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>
xml/searchable.xml
<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:hint="Search" android:label="@string/app_name" >
</searchable>
Main activity lifecycle method which adds icons to the action bar (works fine):
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
// Get the SearchView and set the searchable configuration
SearchManager searchManager = (SearchManager)getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
// Do not iconify the widget;expand it by default
searchView.setIconifiedByDefault(false);
return true;
}
SearchableActivity.java
public class SearchableActivity extends ListActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.d("MY", "search activity triggered");
}
}
Note: The search widget appear on the action bar and I can insert data, but pressing the OK/Enter doesn't take me to the SearchableActivity (doesn't trigger onCreate of the SearchableActivity).
Am I missing something or is the official tutorial flawed?
回答1:
Problem solved: the tutorial seems to missing one important part: <meta-data android:name="android.app.default_searchable" android:value=".MySearchActivityName" />
has to be added inside <application>
tags in manifest to get the search widget working correctly.
EDIT- Also a hint to solving a problem when the actionbar search is not triggered on data posting (no error given whatsoever and documentations hasn't got a word about this limitation): in searchable.xml file android:hint and android:label attributes MUST be references to strings in strings.xml.

回答2:
You should override onOptionsItemSelected
and probably onSearchRequested
in your activity.
回答3:
If "xml/searchable.xml" file is not correctly formatted (things such as "searchable" tag not in all lower case), there is no error message returned during execution and the "SearchableActivity" doesn't get invoked.
