My use case is the following: in activity A, I have an action bar with a collapsible SearchView. When the user gives her query and presses the 'search' button, I would like to show activity B with the results. I'm failing to do so, here is my code:
searchable.xml:
<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:hint="#string/action_search_hint"
android:label="#string/app_name"/>
Activity A:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
return true;
}
AndroidManifest for Activity A and B:
<activity
android:name=".ActivityA">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<activity android:name=".ActivityB">
<intent-filter>
<action android:name="android.intent.action.SEARCH"/>
</intent-filter>
<meta-data
android:name="android.app.searchable"
android:resource="#xml/searchable"/>
</activity>
Howerver, no matter what I try, getSearchableInfo in A always returns null.
I have the feeling I'm not understanding something. The only way I can make getSearchableInfo() return not null is when I put the SEARCH intent filter and the searchable meta-data into activity A in the manifest. But then, when I press the 'search' button, another instance of activity A is started again on top of the current one, which definitely is not what I want. I guess I could add singleTop to A and handle the SEARCH action in onNewIntent and start B, but I generally don't want A to be singleTop, I want the default. Or do I?
I tried adding this to A in the manifest (as suggested in some other threads):
<meta-data
android:name="android.app.default_searchable"
android:value=".ActivityB" >
</meta-data>
What am I doing wrong?
EDIT: I replaced the 'getComponentName()' line in A with the following:
searchView.setSearchableInfo(searchManager.getSearchableInfo(new ComponentName(this, ActivityB.class)));
and it seems to work the way I want! Am I doing something wrong here, or is this the correct way? I'm a bit uncertain because it is not mentioned anywhere!
According to Android documentations, SearchManager.getSearchableInfo(componentName) takes one argument, which is:
componentName: The activity to get searchable information for
In your case you need ActivityB, so constructing a ComponentName that points to ActivityB is the correct way
new ComponentName(this, ActivityB.class)
<intent-filter>
<action android:name="android.intent.action.SEARCH"/>
</intent-filter>
add this intent filter to activity A.
2.SearchView Menu
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
searchView = (SearchView) menu.findItem(R.id.search).getActionView();
searchView.setSearchableInfo(searchManager
.getSearchableInfo(getComponentName()));
xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/search"
android:actionViewClass="android.widget.SearchView"
android:icon="#drawable/ic_action_search"
android:showAsAction="collapseActionView|always"
android:title="#string/search_hint"/>
</menu>
3.Call this method from oncreate.
private void handleIntent(Intent intent) {
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
Debug.e("Suggestion handle click", "call " + query);
startNextActivity(query);
}
}
4. if you are using Autosuggestion Listview implement searchView.setOnQueryTextListener ,setOnSuggestionListener and setSuggestionsAdapter.

I'm trying to implement a search bar on the main Activity of my app. For that, I used the documentation from the android developer website.
I followed the instructions, and I have my search bar where I can put some query. The problem here is that for the few first time when I try to make a search, I have to click 2 times on a search icon.
First, my bar looks like a default one :
Search bar by default
I notice that the icon is not clearly white, it's like there is some transparency in it, but I've selected a full white icon.
Then after a click on the icon, my bar looks like this :
Search bar clicked one time
The icon goes to the left and I have a back button as I was already in the search field.
When I click on the search icon again, I finally have the result that I want :
Search bar in edit mode
When I quit the search bar and do it again, it's the same for 1 or 2 times, and then, I have the normal behavior, I go from the first image to the last just with one click.
Here's my files :
menu_app.xml
<menu xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/search"
android:title="#string/search"
android:icon="#drawable/ic_search"
app:showAsAction="collapseActionView|ifRoom"
app:actionViewClass="android.widget.SearchView" />
</menu>
AndroidManifest.xml
<activity
android:name=".activities.MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<action android:name="android.intent.action.SEARCH"/>
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<meta-data android:name="android.app.searchable"
android:resource="#xml/searchable"/>
</activity>
searchable.xml
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:label="#string/app_name"
android:hint="#string/search"/>
OnCreateOptionsMenu in MainActivity.java
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_main, menu);
// Associate searchable configuration with the SearchView
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
final SearchView searchView = (SearchView) menu.findItem(R.id.search).getActionView();
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String s) {
Log.d(TAG, s);
searchView.clearFocus();
return true;
}
#Override
public boolean onQueryTextChange(String s) {
Log.d(TAG, s);
return false;
}
});
return true;
}
Thanks in advance for your help!
I finally solved it, please look at my comment for the solution.
I know this is a common issue.
However, launching another activity whenever user clicks on the searchView (not the icon) is not working unless user submits the query.
Below are functional codes, that result whenever user submits a query, it launches another activity, however, I want to launch another activity as soon as user clicks on the searchView (expanded textfield).
Thanks in advance.

MainPage.class
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main_page, menu);
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) menu.findItem(R.id.search).getActionView();
searchView.setSearchableInfo(searchManager.getSearchableInfo(new ComponentName(this, SearchActivity.class)));
return true;
}
BTW, I have tried where you can write if/switch statements in onOptionsItemSelected method to identify the searchView id then use Intents. Both did not work.
onCreate method:
Intent intent = getIntent();
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
SearchRecentSuggestions suggestions = new SearchRecentSuggestions(this,
MySuggestionProvider.AUTHORITY, MySuggestionProvider.MODE);
suggestions.saveRecentQuery(query, null);
I do have this in onCreate, for the recent query suggestions, and I am not sure whether if this is the reason for my issue. I'm assuming that, because this is called initially, it suppresses the onOptionsItemSelected method's attributes? Not sure..
Here's a xml for menu
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/action_settings"
android:orderInCategory="100"
android:title="#string/action_settings"
app:showAsAction="never" />
<item android:id="#+id/search"
android:title="#string/title_activity_main_page"
app:showAsAction="always"
app:actionViewClass="android.support.v7.widget.SearchView"
/>
Thanks to some of the alternative methods in implementing the if length is 0 start a new activity, and setting setOnClickListener they have worked but only when I clicked on the logo which did not work when I set the icon to false.
In consideration to pskink's comment, I took a different approach that had solved my issue. It was rather a really simple approach where I got rid of the SearchView and changed that to EditText field to allow instant onClick on a single tap to another activity.
Thank you very much for the alternative thoughts and solutions for the issue. They have been a great help as I will reference them later on and that I now know which works and those that don't.
I am new in android and I am working with a search related feature. After read the tutorial I have some questions:
1 Does the SearchableActivity unique in an application?
It seems that 3 steps are required to setup the search feature(from the android developer guide):
1)create the SearchableActivity to receive the search keyword.
2)make the SearchableActivity to accept the ACTION_SEARCH intent
3)specify the searchable configuration to use, in a element.
Then I wonder if all the search related job will be delegated to the SearchableActivity?
And suppose I have two MainActivity and MainActivityTwo, both of them make a SearchView inside the action bar.
The AndroidMinefset.xml:
<activity android:name="com.app.activity.MainActivityTwo" />
<activity android:name="com.app.activity.MainActivity" />
<activity android:name="com.app.activity.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/search.xml:
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:hint="#string/search_hint"
android:label="#string/app_name" >
</searchable>
And register the search configuration(serchableInfo) toSerchView:
.MainActivity
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.u_action_menu_map, menu);
MenuItem searchItem = menu.findItem(R.id.action_search);
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
return super.onCreateOptionsMenu(menu);
}
This does not work, it seems that there is no serchableInfo bound with the current Activity(MainActivity).
Even I changed to this:
searchView.setSearchableInfo(searchManager.getSearchableInfo(new ComponentName("com.app.activity", "SearchableActivity")));
It still cannot find the searchableInfo.
After I add the search related configuration to MainActivity:
<activity android:name="com.app.activity.MainActivityTwo" />
<activity android:name="com.app.activity.SearchableActivity" />
<activity android:name="com.app.activity.MainActivity"
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>
This worked. WTF.
I always thought that the Activity provide the Search UI and the Activity handle the input are different, but after my test it seems that they are the same Activity, that't to say the user input are submit to the Activity itself,but why use the **ing intent to transfer the input data?
2 The search submit
The Search dialog have a search submit button at the right of the dialog:
But there is nothing inside the SearchView so how to submit the search in a SearchView:
There should be a search key on your keyboard. It can also be go, return or similar keys that should start the search.
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?
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. Source
You should override onOptionsItemSelected and probably onSearchRequested in your activity.
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.
I'm working around with a searchable action bar. And I gotta a problem that the action bar doesn't react with the searchable activity. THAT IS, I enter something in the action bar's searchable textedit then clicked the submit but nothing happened. The debug tracking shows that the code in my searchresultactivity is never executed. So I'm wondering if there's something wrong in searchable configuration. Well this time I think I've explained the problem clearly and I don't expect any negative votes without any words even spits!
I followed the instruction of developer's document beginning with the manifest.xml, the meta-data is added in the searchresult activity:
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".GermanDictionaryActivity"
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=".SearchResultsActivity">
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data android:name="android.app.searchable"
android:resource="#xml/searchable" />
</activity>
</application>
then I initialized the searchview with my menu:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.srhbar, menu);
// Get the SearchView and set the searchable configuration
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
mSrhView = (SearchView) menu.findItem(R.id.search).getActionView();
mSrhView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
mSrhView.setSubmitButtonEnabled(true);
return true;
}
And the searchable item in menu:
<item android:id="#+id/search"
android:title="#string/srh_title"
android:showAsAction="collapseActionView|ifRoom"
android:actionViewClass="android.widget.SearchView" />
Any answer related is appreciated!
I solved the problem by changing this line:
searchView.setSearchableInfo(searchManager.getSearchableInfo(new ComponentName(getApplicationContext(), SearchResultsActivity.class)));
