i know this has been asked many times. i've gone through most of the questions here regarding the above problem. but they didn't really help. i can't find the problem in my code. so here is my code
package com.example.actionbaractivity;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu items for use in the action bar
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_activity_actions, menu);
return super.onCreateOptionsMenu(menu);
}
}
now manifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.actionbaractivity"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="18"
android:targetSdkVersion="18" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/Theme.AppCompat.Light" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
and now the menu xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="#+id/action_search"
android:icon="#drawable/ic_action_search"
android:title="#string/action_search"
android:showAsAction="always|withText"/>
</menu>
and finally the string xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">ActionbarActivity</string>
<string name="hello_world">Hello world!</string>
<string name="action_search"></string>
</resources>
Do in this way:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="#+id/action_search"
android:icon="#drawable/ic_action_search"
android:title="#string/action_search"
android:showAsAction="collapseActionView|always"
android:actionViewClass="android.widget.SearchView" />
</menu>
then in your Activity class:
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
getMenuInflater().inflate(R.menu.main, menu);
MenuItem searchItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) searchItem.getActionView();
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
if(null!=searchManager )
{
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
}
searchView.setIconifiedByDefault(false);
return true;
}

I'm currently learning how to set up a search interface in Android Studio following this guide.
So far I've been following it to the best of my ability, but at this step, I encountered a problem: "Cannot resolve method 'getActionView()'"
My MainActivity
package com.androiddeveloper.searchfunctionality;

inflater.inflate(R.menu.options_menu, menu);
SearchManager searchManager =
(SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView =
(SearchView) menu.findItem(R.id.search.getActionView());
searchView.setSearchableInfo(
searchManager.getSearchableInfo(getComponentName()));
return true;
}
}

Change this
SearchView searchView =
(SearchView) menu.findItem(R.id.search.getActionView());
to
SearchView searchView =
(SearchView) menu.findItem(R.id.search).getActionView();
You should use findItem for getting the item using id.
I am trying to display a SearchView inside the ActionBar of my activity. I followed android developer guide here here
But no SearchView is displayed and I cannot figure out why.
Here there is the code of my activity
public class SearchActivity extends ActionBarActivity {
private String query;
#Override
protected void onCreate(Bundle savedInstanceState) {
FacebookSdk.sdkInitialize(getApplicationContext());
super.onCreate(savedInstanceState);
setContentView(R.layout.search_activity_layout);
Intent intent = getIntent();
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
this.query = intent.getStringExtra(SearchManager.QUERY);
Toast.makeText(this,query, Toast.LENGTH_LONG);
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.options_menu, menu);
return true;
}
}
here the is the serachable.xml file
<?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" />
here there is the options_menu.xml file
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/search"
android:title="#string/search_title"
android:icon="#drawable/ic_action_search"
android:showAsAction="collapseActionView|ifRoom"
android:actionViewClass="android.widget.SearchView" />
</menu>
and this is the manifest
<activity android:name=".SearchActivity"
android:label="SearchActivity">
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data android:name="android.app.searchable"
android:resource="#xml/searchable"/>
</activity>
the only strange thing is that this line (android:showAsAction="collapseActionView|ifRoom") in the options_menu.xml file is highlighted in red.
Try putting this in your options_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/search"
android:title="#string/search_title"
android:icon="#drawable/ic_action_search"
app:actionViewClass="android.widget.SearchView"
app:showAsAction="collapseActionView|ifRoom" />
</menu>
And this in your AndroidManifest.xml
<activity android:name=".SearchActivity"
android:label="SearchActivity">
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data android:name="android.app.searchable"
android:resource="#xml/searchable"/>
<meta-data android:name="android.app.default_searchable"
android:value=".SearchActivity" />
</activity>
And this in your SearchActivity.java
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.options_menu, menu);
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
protected void onNewIntent(Intent intent) {
setIntent(intent);
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
Log.e("query", intent.getStringExtra(SearchManager.QUERY));
}
}
For your reference, hope this helps!

SearchView searchView =
(SearchView) menu.findItem(R.id.search).getActionView();

Try out the following code

android:icon="#android:drawable/ic_menu_search"
android:showAsAction="collapseActionView|ifRoom"
android:actionViewClass="android.widget.SearchView" />
</menu>
I think you are making a mistake in the above code.
Are you using appcompat library?
if no, the above code should work.
if yes, try using app:showAsAction instead of android:showAsAction and
app:actionViewClass="android.support.v7.widget.SearchView" instead of android:actionViewClass="android.widget.SearchView"
manifest
<activity
android:name=".SearchActivity"
android:label="SearchActivity">
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data
android:name="android.app.default_searchable"
android:value=".SearchActivity" />
<meta-data
android:name="android.app.searchable"
android:resource="#xml/searchable" />
</activity>
SearchActivity.java
#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_search, menu);
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) menu.findItem(R.id.search).getActionView();
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
return true;
}
#Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
System.out.println("onNewIntent SearchResults");
handleIntent(intent);
}
private void handleIntent(Intent intent) {
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
System.out.println("Received query: " + query);
}

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:allowBackup="true"
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>
<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"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools" tools:context=".MainActivity">
<item android:id="#+id/action_settings" android:title="#string/action_settings"
android:orderInCategory="100" app:showAsAction="never" />
<item android:id="#+id/action_search"
android:title="Search"
android:icon="#android:drawable/ic_menu_search"
app:showAsAction="always"
android:actionViewClass="android.widget.SearchView" />
</menu>
This is my 2nd activity
public class SearchableActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_searchable);
handleIntent(getIntent());
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.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()));
return true;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.
}
#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
}
}
}
I tried to look up a lot, but only got confused more. Please Help.
I am having trouble displaying my menu options on my phone. I got all the code right I think but it is not displaying. Any help would be greatly appreciated.
Here is how my manifest looks like:

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Here is the onCreateOptionsMenu function:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.mymenu, menu);
return true;
}
and here is the menu xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/file"
android:title="#string/fileTab"

<item

</menu>
If you are using a fragment make sure that you have enabled the options menu with setHasOptionsMenu(true). A good place to call this might be from onCreate.
public class MyFragment extends Fragment {
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
}
or for an Activity
public class MyActivity extends Activity {
#Override
public boolean onCreateOptionsMenu(Menu menu){
super.onCreateOptionsMenu(menu);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.mymenu, menu);
return true;
}
}
Try this :
#Override
public void onAttachedToWindow() {
super.onAttachedToWindow()
openOptionsMenu();
};
If you are using fragment then you have to do this:
//inside constructor
public MyClassFrag(){
setHasOptionsMenu(true);
}
or inside onCreate()
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
So I have an action bar I am trying to learn and when I implement it I see this white spinning circle left of my first menu item. Why is this being shown here?

How can I get rid of this spinning circle before I publish the app? It is an ugly and annoying distraction to the app itself.
Thanks Y'all!
Try commenting out the line requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS); in your onCreate() callback.
