I'm using the SearchView widget in ActionbarSherlock as a follows:
File.java
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getSupportMenuInflater();
inflater.inflate(R.menu.main, menu);
SearchManager searchManager = (SearchManager)getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) menu.findItem(R.id.MenuSearch).getActionView();
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
searchView.setIconifiedByDefault(true);
searchView.setSubmitButtonEnabled(true);
return true;
}
File.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/MenuSearch" android:title="#string/Bs"
android:icon="#drawable/ic_action_search"
android:showAsAction="always|withText"
android:actionViewClass="com.actionbarsherlock.widget.SearchView" >
</item>
</menu>
In my application I get to show the search icon and select it unfolds the search box for the widget, but when I write any search I do not know how to interact with the widget SearchView to launch a new activity and show a series of results.
With the command searchView.setSubmitButtonEnabled(true); appears a icon similar to 'play' and I suppose it is for just that, but I do not know how to interact with it.
Can anyone help?
Official android documentation here describes how start new activity to handle search query and display results.
First you need to create (if you havent already) searchable configuration in res/xml/searchable.xml, like this:
<?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" />
Set this configuration for your activity, that contains SearchView in actionbar, like this (in manifest):
<activity ... >
...
<meta-data android:name="android.app.searchable"
android:resource="#xml/searchable" />
</activity>
So basically, you need your searchable activity (new activity that will start after submitting search query) to handle the android.intent.action.SEARCH action. Declare it in manifest like this:
<activity android:name=".SearchResultsActivity" ... >
...
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
...
</activity>
And your searchable activity should look like this:
public class SearchResultsActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
...
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
}
}
...
}

I am trying to implement WhatsApp like Search in my application.I have to implement the following screen :
As you can see in the screenshot,I have a search icon as option menu .
XML:
<?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">
<item
android:id="#+id/action_search"
android:icon="#drawable/search"
android:orderInCategory="100"
android:title="#string/action_search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="always|collapseActionView" />
</menu>
On clicking search icon search view will be opened .
CODE:
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater menuInflater = getMenuInflater();
menuInflater.inflate(R.menu.menu_friend_list_activity, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_search:
Toast.makeText(getApplicationContext(), "Search button clicked", Toast.LENGTH_SHORT).show();
// Associate searchable configuration with the SearchView
SearchManager searchManager = (SearchManager) FriendsListActivity.this.getSystemService(Context.SEARCH_SERVICE);
if (item != null) {
searchView = (SearchView) item.getActionView();
}
if (searchView != null) {
searchView.setSearchableInfo(searchManager.getSearchableInfo(FriendsListActivity.this.getComponentName()));
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
Log.e("Query",query);
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
return false;
}
});
}
return true;
default:
return super.onOptionsItemSelected(item);
}
}
AndroidManifest.xml
<activity
android:name=".activity.FriendsListActivity"
android:parentActivityName=".activity.WelcomeActivity">
<!-- To display the search view-->
<meta-data
android:name="android.app.searchable"
android:resource="#xml/searchable" />
</activity>
<activity android:name=".activity.SearchResultsActivity">

android:launchMode="singleTop" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
</intent-filter>
</activity>
You can see here i have searchable activity named SearchResultsActivity.
I am following this tutorial.
SearchResultsACtivity:
public class SearchResultsActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
Log.e("onCreate","in SerachActivity called");
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);
Log.e("Query1",query);
//use the query to search your data somehow
}
}
}
I think i am doing something wrong here.When i am trying to search ,SearchResultsActivity is not called .Please help me how can i implement search as WhatsApp do?
I guess you're reading the android tutorial here, that page is very confusing if not completely wrong. There're two places went wrong in your code.
When you call searchView#setSearchableInfo, you're telling Android what activity to launch to handle search result, in your case SearchResultsActivity. So you can't set component name to FriendsListActivity, instead change it to SearchResultsActivity.searchView.setSearchableInfo(searchManager.getSearchableInfo(new ComponentName(this, SearchResultsActivity.class)))
In order for an activity to become a searchable that's able to be found by searchManager, you need to add the android.app.searchable meta-data label to the Activity block in your manifest. Note this label should NOT be added to the activity you display the SearchView, the tutorial page totally states it wrong. So change your SearchResultsActivity to the following.
If you made these two changes, your SearchView from FriendsListActivity would correctly holds a mSearchable instance that's able to start SearchResultsAcitivity. Otherwise it will be null.
<activity android:name=".activity.SearchResultsActivity">
<intent-filter>
<action
android:name="android.intent.action.SEARCH"
android:launchMode="singleTop" />
</intent-filter>
<meta-data
android:name="android.app.searchable"
android:resource="#xml/searchable"/>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
</intent-filter>
</activity>
You have wrote like this: (so you passed FriendsListActivity instead of SearchResult Activity):
searchView.setSearchableInfo(searchManager.getSearchableInfo(FriendsListActivity.this.getComponentName()));
but you should pass the componentName like this:
ComponentName componentName = new ComponentName(FriendsListActivity.this , SearchResultsActivity.class);
searchView.setSearchableInfo(searchManager.getSearchableInfo(componentName));
i am working on action bar . i want to add searchview option on the action bar but app crash here.
this is crash
this is my code of option menu xml
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/search"
android:title="Search"
android:icon="#drawable/search"
android:showAsAction="collapseActionView|ifRoom"
android:actionViewClass="android.widget.SearchView"/>
this is the code of searchable.xml
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:hint="#string/enter"
android:includeInGlobalSearch="false"
android:label="#string/search"
android:searchSettingsDescription="#string/search_global_description" />
and this is my activity code
public class Thrd extends ActionBarActivity {
Menu m;
final Context context=this;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_thrd);

// Add SearchWidget.
SearchManager searchManager = (SearchManager) getSystemService( Context.SEARCH_SERVICE );
SearchView searchView = (SearchView) menu.findItem( R.id.search ).getActionView();
searchView.setSearchableInfo( searchManager.getSearchableInfo( getComponentName() ) );

return true;
case R.id.action_Exit:
openExit();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
private void openExit() {
}
}
please help me to solve my problem.thanks advance
This was how I implemented my search handling.
In the XML folder under layout, add a searchable.xml file and put this code like so:
<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:label="#string/app_name"
android:hint="Search Trends" />
Then in your ANDROID manifest file, add
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:screenOrientation="portrait">
<intent-filter>
<action android:name="com.tobisoft.trendify.MainActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
//This is the meta to add for your activity
<meta-data
android:name="android.app.default_searchable"
android:value=".SearchResultsActivity" />
</activity>
Also you would need to make an activity for the search results like so:
<activity
android:name=".SearchResultsActivity"
android:label="#string/app_name"
android:theme="#style/MyMaterialTheme">
<!-- to identify this activity as "searchable" -->
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
<meta-data
android:name="android.app.searchable"
android:resource="#xml/searchable" />
</activity>
now in the menu folder, with a file name main.xml (or anything you are using)
<item
android:id="#+id/action_search"
android:icon="#drawable/ic_action_search"
android:orderInCategory="100"
android:title="#string/action_search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="always" />
You can get the icon yourself by a simple google search. You would also need to add the AppCompat Library to your project, something you can also do from a simple google search. In the SearchResultsActivity, add this:
public class SearchResultsActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_result);
handleIntent(getIntent());
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, 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;
}
#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
}
}
}
The activity_result.xml layout file is this :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ff141414">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFF"
android:textSize="#dimen/_25sdp"
android:textStyle="bold"
android:text="Search Result goes here!"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true" />
</RelativeLayout>
In your MainActivity.java add this:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, 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;
}
All this shld help your app on the right track. Hope it helps
Changing to import android.support.v7.widget.SearchView helped me and also change these lines
MenuItem searchItem = menu.findItem(R.id.action_search);
SearchView searchView= (SearchView) searchItem.getActionView();
searchView.setOnQueryTextListener(this);`
Level:Beginner
I am trying to implement a search bar on ActionBar. I want that when someone clicks the search icon, he should get a text field, where he simply fills in the text and can search by submitting through the keyboard search Button. Following several tutorials, I am quite confused.
When I do not add
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
searchView.setIconifiedByDefault(false);
I get an icon for search, but it does not expands into a text field. So I am not able to search anything from there.
when I add
`searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
searchView.setIconifiedByDefault(false); `
I get an error 'unfortunately, Application has stopped' and the logcat shows:-
Process: com.example.bhavya.myapplication, PID: 23261
java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.SearchView.setIconifiedByDefault(boolean)' on a null object reference
at com.example.bhavya.myapplication.MainActivity.onCreateOptionsMenu(MainActivity.java:27)
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
searchView.setIconifiedByDefault(false);
return true;
}
I also tried to set 'intent-filter' and 'meta-data' in the following way after I was unsuccesful
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.bhavya.myapplication" >
<application

android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<meta-data android:name="android.app.default_searchable"
android:value=".SearchableActivity"/>
</activity>
<activity
android:name=".SearchableActivity"
android:label="#string/title_activity_searchable" >
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data android:name="android.app.searchable"
android:resource="#xml/searchable"/>
</activity>
</application>
but nothing changed, I also made a folder "xml" and set searchable configuration
<?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/app_name" >
</searchable>
This is my menu.
<menu xmlns:android="http://schemas.android.com/apk/res/android"

This is my 2nd activity
public class SearchableActivity extends ActionBarActivity {

private void handleIntent(Intent intent) {
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
//use the query to search
}
}
}
I tried to look up a lot, but only got confused more. Please Help.
I have 2 activities: the first has a action bar with a search view, the second should display the results of the search query.
androidmanifest:
<activity
android:name=".SearchActivity"
...
android:launchMode="singleTop">
<meta-data
android:name="android.app.searchable"
android:resource="#xml/searchable" />
...
</activity>
<activity
android:name=".ResultsActivity"
...
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
</activity>
searchable.xml
<searchable
xmlns:android="http://schemas.android.com/apk/res/android"
android:label="#string/app_name"
android:hint="#string/enter_a_word" />
SearchActivity
....
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_noun_list, menu);
// Associate searchable configuration with the SearchView
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) menu.findItem(R.id.search).getActionView();
searchView.setSearchableInfo( searchManager.getSearchableInfo(getComponentName()));
return true;
}
....
ResultsActivity:
#Override
protected void onCreate(Bundle savedInstanceState) {
...
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
}
...
}
the problem is that after a query is entered into the searchview, nothing happens. No errors, nothing. How can i open the resultsactivity after the query is entered in the searchactivity?
This answer is a little late but I feel it'll be useful for future viewers. The dilemma seems to come from the ambiguity of the Android SearchView tutorial. The scenario they cover assumes you will be displaying the results in the same Activity the SearchView resides. In such a scenario, the Activity tag in the AndroidManifest.xml file would look something like this:
<activity
android:name=".MainActivity"
android:label="#string/main_activity_label"
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>
Then, to handle the results in the same Activity, you would Override the onNewIntent method:
#Override
public void onNewIntent(Intent intent){
setIntent(intent);
if(Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
//now you can display the results
}
}
However, in a situation where we want to display the results in another Activity, we must put the Intent Filter and meta tag into the results Activity and introduce a new meta tag for the SearchView Activity. So, our Activities will look something like this in the AndroidManifest.xml file:
<activity
android:name=".MainActivity"
android:label="#string/main_activity_label"
android:launchMode="singleTop">
<!-- meta tag points to the activity which displays the results -->
<meta-data
android:name="android.app.default_searchable"
android:value=".SearchResultsActivity" />
</activity>
<activity
android:name=".SearchResultsActivity"
android:label="#string/results_activity_label"
android:parentActivityName="com.example.MainActivity">
<!-- Parent activity meta-data to support 4.0 and lower -->
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.MainActivity" />
<!-- meta tag and intent filter go into results activity -->
<meta-data android:name="android.app.searchable"
android:resource="#xml/searchable" />
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
</activity>
Then, in our MainActivity's onCreateOptionsMenu method, activate the SearchView (assumes you're adding the SearchView to the ActionBar). Rather than using getComponentName() in the SearchManager's getSearchableInfo() method call, we instantiate a new ComponentName object using the MainActivity's context and the SearchResultsActivity 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.menu_home, menu);
SearchView search = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.action_search);
// Associate searchable configuration with the SearchView
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
search.setSearchableInfo(searchManager.getSearchableInfo(new ComponentName(this, SearchResultsActivity.class)));
search.setQueryHint(getResources().getString(R.string.search_hint));
return true;
}
Finally, in our SearchResultsActivity class, in the onCreate method, we can handle the search results:
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
//use the query to search your data somehow
}
}
Don't forget to create the searchable.xml resource file and add the SearchView to your layout.
searchable.xml (res/xml/searchable.xml; create xml folder under res if needed):
<?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"
android:voiceSearchMode="showVoiceSearchButton|launchRecognizer"/>
Layout (example of adding the SearchView to ActionBar as a menu item):
<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="com.example.MainActivity">
<group android:checkableBehavior="single">
<item android:id="#+id/action_search" android:title="Search"
android:orderInCategory="1" app:showAsAction="collapseActionView|ifRoom"
app:actionViewClass="android.support.v7.widget.SearchView"/>
</group>
</menu>
Resources:
Display Results In Same Activity
Display Results In Different Activity
ComponentName
I understood the problem i had also faced the same, This is happening because you are passing the current component name by passing the
getComponentName()
This will be initialize by the current activity name so you need to initialize it with the searchable activity name in given below format and pass the same Component instance it starts the new activity.
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
search.setSearchableInfo(searchManager.getSearchableInfo(new ComponentName(this, SearchResultsActivity.class)));
search.setQueryHint(getResources().getString(R.string.search_hint));
Hope it I have answered the Question!
Without seeing your activity code, I would suggest you try this approach - also assuming you have all the files created as stated above;
In your results activity,
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.core_actions, menu);
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
searchView.setIconifiedByDefault(false);
searchView.setQueryHint(getString(R.string.search_hint));
searchView.setOnQueryTextListener(this);
return true;
}
Remember that this is the activity that has your data that you want to make searchable:
You must implement the SearchView.OnQueryTextListener interface in the same activity:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_search:
ProductsResulstActivity.this.finish();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
#Override
public boolean onQueryTextSubmit(String query) {
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
productFilterAdapter.getFilter().filter(newText);
if (TextUtils.isEmpty(newText)) {
listView.clearTextFilter();
}
else {
listView.setFilterText(newText);
}
return true;
}
productFilterAdapter is the adapter that you must create beforehand.
It should implement Filterable interface. I hope this helps.
If you need further assistance, please let me know. Good luck
I try to make SearchView in action bar to start a SearchResultsActivity which is registered to handle ACTION_SEARCH. I do all required steps but still didn't work!
Here's the code:
1. Search View menu item: (menu/main.xml)
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/search_action"
android:icon="#android:drawable/ic_menu_search"
android:actionViewClass="android.widget.SearchView"
android:showAsAction="always|collapseActionView"
/>
</menu>
2. Searchable configuration (xml/searchable.xml):
<?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"/>
2.1 adding Searchable configuration link to MainActivity in AndroidManifest.xml:
<activity
android:name="com.me.searchonpre3.MainActivity"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
<meta-data
android:name="android.app.searchable"
android:resource="#xml/searchable"/>
</activity>
3. Bind the Search View menu item with the search configuration (MainActivity.java):
public boolean onCreateOptionsMenu(Menu 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){
SearchView searchView = (SearchView) menu.findItem(R.id.search_action).getActionView();
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
if (searchView != null) {
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
}
}
return true;
}
4. add new Activity "SearchResultsActivity" and mark it to handle SEARCH_ACTIONs:
public class SearchResultsActivity extends ListActivity {
public static final String TAG = SearchResultsActivity.class.getSimpleName();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.i(TAG, "In SearchResult OnCreate");
setContentView(R.layout.activity_search_results);
this.setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,
new String[]{"Product1", "Product2"}));
}
}
AndroidMainfest.xml:
<activity
android:name="com.me.searchonpre3.SearchResultsActivity"
android:label="#string/title_activity_search_results">
<intent-filter>
<action android:name="android.intent.action.SEARCH"/>
</intent-filter>
</activity>
All the above settings and the SearchResultsActivity is not started when press the Search keyboard icon.
What else Should I do???
Note: When I add a setOnQueryTextListener, the callbacks being called on the MainActivity class.
It seems that Android tutorials are misleading.
