MenuItemCompat.getActionView(searchItem) return null - android

I am trying to add actions items in my action bar using appcompat. I added search action when I click on it my application crash with NullPointerException. In onCreateOptionsMenu I am getting this view reference but there I am always getting null. Any suggestion to resolve this ??
main.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/action_bar_refresh"
android:icon="#drawable/ic_action_refresh"
app:showAsAction="ifRoom"
android:title="#string/action_refresh" />
<item
android:id="#+id/action_bar_search"
android:icon="#drawable/ic_action_search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="ifRoom"
android:title="#string/action_search" />
<item
android:id="#+id/action_bar_settings"
android:title="#string/action_settings"
app:showAsAction="never" />
</menu>
MainActivity.java
public class MainActivity extends ActionBarActivity {
private SearchView mSearchView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#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, menu);
MenuItem searchItem = menu.findItem(R.id.action_bar_search);
mSearchView = (SearchView) MenuItemCompat.getActionView(searchItem);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_bar_search:
mSearchView.setIconified(false);
return true;
}
return false;
}
}
Here I am getting null value in searchView
MenuItem searchItem = menu.findItem(R.id.action_bar_search);
mSearchView = (SearchView) MenuItemCompat.getActionView(searchItem);
Screenshot

<item
android:id="#+id/action_bar_search"
android:icon="#drawable/ic_action_search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="collapseActionView|ifRoom"
android:title="#string/action_search" />
You change showAsAction attribute.

I fixed issue by setting Application Theme to Theme.AppCompat.Light
<style name="AppBaseTheme" parent="#style/Theme.AppCompat.Light">

Searchview interfering with other buttons

I have a searchview next to a filter button, but ever time I click on the other button the searchview also listens and expands, here is a snippet of the before How the buttons are positioned
When filter button is clicked
and here is my menu layout:
<?xml version="1.0" encoding="utf-8"?>
<item
android:id="#+id/action_search"
android:icon="#drawable/ic_search_black_24dp"
android:title="#string/search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="ifRoom|collapseActionView" />
<item
android:id="#+id/action_sort"
android:icon="#drawable/ic_filter_list_black_24dp"
android:title="#string/Sort"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="ifRoom|collapseActionView" />
</menu>
my Java code:
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.activty_ecommerce_sort, menu);
SearchManager manager = (SearchManager) getContext().getSystemService(Context.SEARCH_SERVICE);
final SearchView search = (SearchView) menu.findItem(R.id.action_search).getActionView();
search.setSearchableInfo(manager.getSearchableInfo(getActivity().getComponentName()));
search.setActivated(true);
search.setQueryHint("Search");
search.onActionViewExpanded();
search.setIconified(false);
search.clearFocus();
search.setOnQueryTextListener(this);
super.onCreateOptionsMenu(menu, inflater);
}
#Override
public boolean onOptionsItemSelected(MenuItem menuItem) {
int id = menuItem.getItemId();
switch (id){
case R.id.action_sort:
filterDailog();
break;
}
return super.onOptionsItemSelected(menuItem);
}
Anyone have an idea where the issue is?
You need to remove app:actionViewClass="android.support.v7.widget.SearchView" from sort item.
<item
android:id="#+id/action_sort"
android:icon="#drawable/ic_filter_list_black_24dp"
android:title="#string/Sort"
app:showAsAction="ifRoom|collapseActionView" />
instead of;
<item
android:id="#+id/action_sort"
android:icon="#drawable/ic_filter_list_black_24dp"
android:title="#string/Sort"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="ifRoom|collapseActionView" />

Search View with collapseActionView|always does not work on Action Menu

In an AppCompat activity with context action bar
Trying to add android.support.v7.widget.SearchView to the action mode menu
the searchView doesn't expand
using appcompat-v7:25.2.0

<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="windowActionModeOverlay">false</item>
<item name="actionModeBackground">#color/colorPrimaryDark</item>
</style>
Activity code
private class SelectionActionModeCallBack implements ActionMode.Callback {
private SearchView mSearchView;
SelectionActionModeCallBack() {
}
#Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
mode.getMenuInflater().inflate(R.menu.book_selection_action_menu, menu);//Inflate the menu over action mode
mSearchView =
(SearchView) menu.findItem(R.id.action_search).getActionView();
mSearchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String s) {
startSearch(s);
return true;
}
#Override
public boolean onQueryTextChange(String s) {
return false;
}
});
return true;
}
#Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
mSearchView.requestFocus();
return true;
}
This contradicts the documentation
Contrary to the case when using Search View in action bar the desired collapsible effect for search view while having other items in the action mode
use
app:showAsAction="always"
without collapseActionView !

Back button of Searchview

I'm using Toolbar and SearchView for the ActionBar. After submit query text, It's changed like the picture below. How to set OnClick to the back button?
Edit 1: Here are involve code
menu.xml
<item
android:id="#+id/action_search"
android:orderInCategory="100"
android:title="#string/action_settings"
android:icon="#drawable/ic_search_white"
app:showAsAction="always|collapseActionView"
app:actionViewClass="android.support.v7.widget.SearchView"/>
In my Fragment class
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.menu_main, menu);
final MenuItem myActionMenuItem = menu.findItem(R.id.action_search);
final SearchView searchView = (SearchView) MenuItemCompat.getActionView(myActionMenuItem);
final ImageView mCloseButton = (ImageView) searchView.findViewById(android.support.v7.appcompat.R.id.search_close_btn);
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(final String query) {
if (!searchView.isIconified()) {
searchView.setIconified(true);
}
mCloseButton.performClick();
return false;
}
...
Simply add android:showAsAction="always|collapseActionView" in your menu item.
Example menu.xml
<?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="#drawable/ic_search_white_24dp"
android:showAsAction="always|collapseActionView"
android:actionViewClass="android.widget.SearchView" />
</menu>

How to make the Action Bar SearchView fill Entire action bar?

I was trying to create an action bar search in my application, but in the expanded state the SearchView is not taking the entire action bar width( it is still showing other actions)!
So, how to make the SearchView fill the full ActionBar Area (as in GMAIL app)?
None of the above solutions worked for me. Setting the MaxWidth of the SearchView worked for me:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_search, menu);
SearchView searchView = (SearchView)menu.findItem(R.id.menu_search).getActionView();
searchView.setMaxWidth(Integer.MAX_VALUE);
Got it
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.my_swipe_tabbed, menu);
MenuItem searchViewItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) searchViewItem.getActionView();
searchView.setIconifiedByDefault(false);
ActionBar.LayoutParams params = new ActionBar.LayoutParams(ActionBar.LayoutParams.MATCH_PARENT, ActionBar.LayoutParams.MATCH_PARENT);
searchView.setLayoutParams(params);
searchViewItem.expandActionView();
return true;
}
<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=".MySwipeTabbedActivity" >
<item android:id="#+id/action_search"
android:title="Search"
android:icon="#android:drawable/ic_menu_search"
android:showAsAction="always|collapseActionView"
android:actionViewClass="android.widget.SearchView"
/>
<item android:id="#+id/action_share"
android:title="Share"
android:icon="#android:drawable/ic_menu_share"
android:showAsAction="ifRoom" />
<item android:id="#+id/action_settings"
android:title="Settings"
android:icon="#android:drawable/ic_menu_preferences"
android:showAsAction="never" />
</menu>
[Optional] Avoid the searchView from collapsing:
searchViewItem.setOnActionExpandListener(new MenuItem.OnActionExpandListener() {
#Override
public boolean onMenuItemActionExpand(MenuItem item) {
return true;
}
#Override
public boolean onMenuItemActionCollapse(MenuItem item) {
return false; //never collapse
}
});
The Answer given by #Hiep is correct i followed those steps to get my solution.but i was using ActionbarCompact lib so it take some changes to made so that i get it to work This solution is only the modified answer of Hiep if you are using appcompact
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:materialdesign="http://schemas.android.com/apk/res-auto" >
<item android:id="#+id/action_search"
android:title="search"
android:icon="#drawable/abc_ic_search_api_mtrl_alpha"
materialdesign:showAsAction="always|collapseActionView"
materialdesign:actionViewClass="android.support.v7.widget.SearchView" />
</menu>
And in the Main Class onCreateOptionsMenu
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.my_swipe_tabbed, menu);
MenuItem searchItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
// Get the SearchView and set the searchable configuration
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
ActionBar.LayoutParams params = new ActionBar.LayoutParams(ActionBar.LayoutParams.MATCH_PARENT, ActionBar.LayoutParams.MATCH_PARENT);
searchView.setLayoutParams(params);
searchView.setIconified(false);
MenuItemCompat.expandActionView(searchItem);
return super.onCreateOptionsMenu(menu);
}
Avoid the searchView from collapsing:If u use the above method in Appcompact it will create a crash so use this solution to avoid that.
MenuItemCompat.setOnActionExpandListener(searchItem, new MenuItemCompat.OnActionExpandListener() {
/* (non-Javadoc)
* #see android.support.v4.view.MenuItemCompat.OnActionExpandListener#onMenuItemActionExpand(android.view.MenuItem)
*/
#Override
public boolean onMenuItemActionExpand(MenuItem item) {
return true;
}
/* (non-Javadoc)
* #see android.support.v4.view.MenuItemCompat.OnActionExpandListener#onMenuItemActionCollapse(android.view.MenuItem)
*/
#Override
public boolean onMenuItemActionCollapse(MenuItem item) {
return false;
}
});
Thank you
Try This Only will work and keep all other items set to ifRoom
<item
android:id="#+id/action_search"
app:actionViewClass="android.support.v7.widget.SearchView"
android:title="#string/action_search"
app:showAsAction="always"/>
Yes, I'm really late :)
But I would like to share one more alternative solution. The idea is just to hide the grouped menu items when the SearchView gets expanded.
Step 1:
Group your menu items. Please make sure showAsAction of search view item is app:showAsAction="collapseActionView|always"
<group android:id="#+id/myMenuGroup">
<item
android:id="#+id/actionSearch"
android:icon="#drawable/ic_search"
android:title="#string/search"
app:actionViewClass="android.widget.SearchView"
app:iconTint="#color/textColorVariant2"
app:showAsAction="collapseActionView|always" />
<item
android:id="#+id/actionFilter"
android:icon="#drawable/ic_filter"
android:orderInCategory="0"
android:title="#string/filter"
app:iconTint="#color/textColorVariant2"
app:showAsAction="ifRoom" />
..... </group>
Step 2: Get the menu reference in onPrepareOptionsMenu() callback
override fun onPrepareOptionsMenu(menu: Menu?): Boolean {
super.onPrepareOptionsMenu(menu)
this.menu = menu // this.menu is a global scoped variable
return true
}
Step 3
Add MenuItem.OnActionExpandListener into your activity and implement onMenuItemActionExpand() and onMenuItemActionExpand() like below
override fun onMenuItemActionExpand(p0: MenuItem?): Boolean {
menu?.setGroupVisible(R.id.myMenuGroup, false)
return true
}
override fun onMenuItemActionCollapse(p0: MenuItem?): Boolean {
menu?.setGroupVisible(R.id.myMenuGroup, true)
return true
}
This approach will expand the SearchView completely inside the ActionBar even if there are other menu icons present

SearchView Widget not showing up in Action Bar

This can be considered as a extension of this Question
I have added following to the code to get a searchView Widget
res/menu/main_activity_actions.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- Search, should appear as action button -->
<item android:id="#+id/action_search"
android:icon="#drawable/ic_action_search"
android:title="#string/action_search"
android:showAsAction="always"
android:actionViewClass="android.support.v7.widget.SearchView" />
<!-- Settings, should always be in the overflow -->
<item android:id="#+id/action_settings"
android:title="#string/action_settings"
android:showAsAction="never" />
</menu>
Mainactivity.java
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_activity_actions, menu);
MenuItem searchItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
System.out.println("TESTING: "+searchView);
return super.onCreateOptionsMenu(menu);
}

}
The app shows up fine but on touching the search button nothing shows up.
Have set the Sdk versions as follows:(4.0.3 -4.2.2)
android:minSdkVersion="15"
android:targetSdkVersion="17"
Change you menu to,
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:yourapp="http://schemas.android.com/apk/res-auto">
<item android:id="#+id/action_search"
android:icon="#drawable/ic_action_search"
android:title="#string/action_search"
yourapp:actionViewClass="android.support.v7.widget.SearchView"
yourapp:showAsAction="always" />
</menu>
You're missing "collapseActionView" in your menu:
app:showAsAction="ifRoom|collapseActionView"
