Searchview in android Toolbar

I am trying to build a searchview in the toolbar ion my android app, but am getting a null pointer exception in the 3rd line of onCreateoptionsMenu method. Any help will be appreciated, thank you in advance.
#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.search).getActionView();
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
return true;
}
Here is my menu.xml -
<item
android:icon="#drawable/ic_search"
android:id="#+id/action_search"
android:orderInCategory="200"
android:title="Search"
app:showAsAction="ifRoom" />

Set SearchView class in menu.
<item
android:icon="#drawable/ic_search"
android:id="#+id/action_search"
android:orderInCategory="200"
android:title="Search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="ifRoom" />

You missd app:actionViewClass="android.support.v7.widget.SearchView" attribute.
And you need to import android.support.v7.widget.SearchView;
<?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:title="#string/Search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="always|collapseActionView" />
</menu>

You forgot to add actionViewClass in menu.xml
Add these line to you menu.xml
...
app:showAsAction="always|collapseActionView"
android:actionViewClass="android.support.v7.widget.SearchView" />
While in your Java code find SearchView using -
SearchView searchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.action_search));
Reference - MenuItemCompat

Try to use this
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
// Inflate menu to add items to action bar if it is present.
inflater.inflate(R.menu.menu_main, menu);
// Associate searchable configuration with the SearchView
SearchManager searchManager =
(SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView =
(SearchView) menu.findItem(R.id.menu_search).getActionView();
searchView.setSearchableInfo(
searchManager.getSearchableInfo(getComponentName()));
return true;
}
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:appcompat="http://schemas.android.com/apk/res-auto"
xmlns:app="http://schemas.android.com/tools">
<item
android:id="#+id/action_settings"
android:title="#string/action_settings"
android:orderInCategory="100"
app:showAsAction="never"/>
<item
android:id="#+id/menu_search"
android:title="#string/menu_search"
appcompat:actionViewClass="android.support.v7.widget.SearchView"
appcompat:showAsAction="always"/>

Try changing this line:
SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();

Android: menu displaying at screen bottom

I was trying to create a menu, and add some actions "ifRoom" using code below:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/menu_search"
android:icon="#android:drawable/ic_menu_search"
android:actionViewClass="android.widget.SearchView"
android:showAsAction="ifRoom|collapseActionView"
android:title="#string/search_description" />
<item
android:id="#+id/menu_refresh"
android:title="#string/menu_refresh"
android:showAsAction="ifRoom|withText"
/>
<item
android:id="#+id/menu_preference"
android:title="#string/menu_preferences"
android:showAsAction="never"
/>
</menu>
But what i got is the menu is displaying at the bottom...
I want it to be at top of the screen...
Any idea what happened here? Thanks!

Below is the MainActivity.java onCreateOptionaMenu method:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_menu, menu);
// Moved from onCreate -- Retrieve the Search View and configure/enable it
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()) );
return true;
}

Android: strange SearchView's behavior

I'm trying to implement SearchView according to some online tutorials. But when i clicked the search icon, it did not expand, instead another search icon appeared to the left and i must click again; this time it worked.
Are there something i'm missing here?
Here are the captured images, sorry i can't post these to stackoverflow yet.

If i delete collapseActionView then it worked, but i can't customize search icon.
<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/search"
android:title="#string/search_title"
android:icon="#drawable/ic_action_search"
app:showAsAction="collapseActionView|ifRoom"
app:actionViewClass="android.widget.SearchView"/>
</menu>
In MainActivity.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_main, menu);
// Associate searchable configuration with the SearchView
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
MenuItem searchItem = menu.findItem(R.id.search);
mSearchView = (SearchView) searchItem.getActionView();
mSearchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
mSearchView.setIconifiedByDefault(true);
mSearchView.setOnSearchClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
showResultsFragment();
}
});
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
boolean toggleHandled = mDrawerToggle.onOptionsItemSelected(item);
return toggleHandled || super.onOptionsItemSelected(item);
}
Thank in advance!

in your menu xml i changed app:actionViewClass="android.support.v7.widget.SearchView"
<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/search"
android:title="wrwrwr"
android:icon="#drawable/abc_ic_menu_copy_mtrl_am_alpha"
app:showAsAction="collapseActionView|ifRoom"
app:actionViewClass="android.support.v7.widget.SearchView"/>
</menu>
and in your activity
import android.support.v7.widget.SearchView; //don't import android.widget.SearchView

Remove searchView icon

In my app, I'm using a SearchView in the actionbar that it's always expanded like this:
My main.xml is this:
<item
android:id="#+id/menu_search"
android:actionViewClass="android.widget.SearchView"
android:showAsAction="always"
android:title="Search" />
MainActivity.java:
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
MenuItem searchViewItem = menu.findItem(R.id.menu_search);
SearchView searchView = (SearchView) searchViewItem.getActionView();
searchView.setIconifiedByDefault(false);
return true;
}
I would like to remove the search icon and expand the editText.

changing the position of the search icon

I use SearchView in OptionsMenu:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/action_search"
android:title="Search"
android:icon="#drawable/icon_search"
android:showAsAction="always"
android:actionViewClass="android.widget.SearchView" />
</menu>
In main activity:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_search, menu);
View inflatedView = getLayoutInflater().inflate(R.layout.arrow, null);
MenuItem searchItem = menu.findItem(R.id.action_search);
mSearchView = (SearchView) searchItem.getActionView();
setupSearchView(searchItem);
return (super.onCreateOptionsMenu(menu));
}
The search icon located on the right in menu. How to change its position in my menu? I want that it is located left.
