I implemented SearchView in Actionbar before using appcompat.v7
but when I want to use the SearchView with support library v7 it shows null exception
In style
<item android:id="#+id/action_search"
android:title="#string/action_search"
android:icon="#drawable/ic_action_search"
app:showAsAction="always|collapseActionView"
android:actionViewClass="android.support.v7.widget.SearchView" />
In Java Class:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
searchView.setOnQueryTextListener(this);
return super.onCreateOptionsMenu(menu);
}
My question is how to declare SearchView in onCreateOptionsMenu to be able to set query listener?
You should use the static methods in MenuItemCompat do deal with all AppCompat menu items. This was mentioned in this blog post as the last item under 'New Integration'. Just replace your SearchView declaration with the following.
SearchView searchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.action_search));
Here's a link to the MenuItemCompat documentation.
Edit:
I just assumed you are using the latest version of AppCompat with the support for the new Toolbar widget.
If you change android:actionViewClass to app:actionViewClass your existing code will continue working.

I have an application with a search widget in the action bar. The application is not creating the search widget as an actionview when I switch the theme to use Material.Light in android L. When debugging I can see that the search view is null.
The menu item:
<item
android:id="#+id/search"
android:icon="#android:drawable/ic_menu_search"
android:title="#string/title"
app:actionViewClass="android.widget.SearchView"
app:showAsAction="always" />
The creation of the menu:
Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.homescreen, menu);
return true;
}
The initialization of a variable for the search view:
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
SearchView searchView = (SearchView) menu.findItem(R.id.search).getActionView();
searchView.setOnQueryTextListener(queryListener);
return super.onPrepareOptionsMenu(menu);
}
Any ideas?
Update 1:
Ok so I stopped the app from crashing by replacing app:actionViewClass="android.widget.SearchView" with android:actionViewClass="android.widget.SearchView". But now the search item shows up in the overflow menu rather than the action bar even though it is set to show as action always.
I had this same problem with setting it to show "always" and it ended up always being in the overflow. If you are using the support library make sure you are extending ActionBarActivity, if not, the regular Activity should work.
I am using actionbar compat support library to provide search widget in Action Bar. The search action view is collapsing only after pressing back button or up button twice. I had same problem while executing the sample dictionary search also.
Code in my search activity which extends ActionBarActivity
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu
getMenuInflater().inflate(R.menu.menu_main, menu);
// Find the search item
MenuItem searchItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
return super.onCreateOptionsMenu(menu);
}
My Searchable.xml looks like this
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:label="#string/search_label"
android:hint="#string/search_hint"
android:voiceSearchMode="showVoiceSearchButton|launchRecognizer"
>
Let me know if any more information needed...
Check the API guide http://developer.android.com/guide/topics/ui/actionbar.html#ActionView This is what it should look for anything less than API 11.
<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"
yourapp:orderInCategory="9"
yourapp:menuCategory="system"
yourapp:showAsAction="always|collapseActionView"
yourapp:actionViewClass="android.widget.SearchView"
android:title="#string/action_searchSt" />
</menu>
That's probably more attributes than you need (menuCategory and orderInCategory are unnecessary). But assuming you've added in the support library correctly and you read the link I gave, things should work as intended.
i tried to put a searchbar into my app and i got it so far to type in what i wanna search, but how do i "send" that given information?
The problem is i can type something in, but theres no button to start the search and i dont have much experience in app building...
the menu:
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.klassenliste, menu);
SearchManager searchManager =
(SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView =
(SearchView) menu.findItem(R.id.search).getActionView();
searchView.setSearchableInfo(
searchManager.getSearchableInfo(getComponentName()));
return true;
}
xml files
searchable.xml
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:label="#string/app_name"
android:hint="#string/search_hint" />
and a menu file:
klassenliste.xml
<item
android:id="#+id/action_settings"
android:orderInCategory="100"
android:showAsAction="never"
android:title="#string/action_settings"/>
<item android:id="#+id/search"
android:title="#string/search_title"
android:icon="#drawable/ic_btn_search"
android:showAsAction="collapseActionView|ifRoom"
android:actionViewClass="android.widget.SearchView"></item>
The actual "sending" of the search query is done with the assistance of the Android system itself. That said, you still need to specify which activity to launch to process and display the search query.
Assume that SearchActivity is your target activity for showing/processing search queries. See my answer here. Also, your onCreateOptionsMenu(Menu menu) method seems to be missing important lines of code. Refer the docs. Use a SearchView if developing for Android 3.0+ and using an ActionBar.
I switched from ActionBarSherlock to ActionBarCompat (support library v7). After some adjustments, almost everything is working fine by now.
But I'm in trouble with the SearchView in the ActionBar. When it's expanded (actually, It's always expanded in my Activity), it takes up all the space and doesn't respect the space of other Action Items that are set to show always (showAsAction="always").
To simulate the problem, use this:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/menu_buscar"
app:actionViewClass="android.support.v7.widget.SearchView"
android:icon="#drawable/abc_ic_search"
app:showAsAction="always"
android:title="#string/buscar"/>
<item android:id="#+id/tentar_novamente"
android:title="#string/tentar_novamente"
android:icon="#drawable/acao_tentar_novamente"
app:showAsAction="always" />
</menu>
In the Activity:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.busca_action_menu, menu);
searchMenuItem = menu.findItem(R.id.menu_buscar);
searchView = (SearchView) MenuItemCompat.getActionView(searchMenuItem);
searchView.setIconifiedByDefault(false);
searchView.setQueryHint(stringBusqueArtistasMusicasEAlbuns);
return super.onCreateOptionsMenu(menu);
}
This is the result in the android 4.3:
And this is the result in the android 2.3 (the action items doesn't even appear):
The same problem happens when I use:
setSupportProgressBarIndeterminateVisibility(true);
The progress indicator appears very strange in the Android 4.3 and doesn't appear in Android 2.3.
The same code worked as expected with ActionBarSherlock. When there was some action item, the SearchView used to decrease its width to give space for the action items.
UPDATE:
I've posted an issue in the Android's Bug Tracker:
https://code.google.com/p/android/issues/detail?id=58251&thanks=58251&ts=1375191632
If you have the same problem, please follow the issue.
UPDATE:
I've tried to put the action items before the SearchView and this way they items appear.
But, the setSupportProgressBarIndeterminateVisibility(true) is still not showing the progress bar.
This is definitely a bug about Android but a workaround can be including SearchView programmatically like this:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
SearchView searchView = new SearchView(getSupportActionBar().getThemedContext());
searchView.setIconifiedByDefault(false);
getActionBar().setCustomView(searchView);
getActionBar().setDisplayShowCustomEnabled(true);
}
You can also use a layout XML to define SearchView properties.
However "iconifiedByDefault" in XML tends to be ineffective in my experience. (This may my bad though)
Thanks for creating an issue about this.
Here's the URL to the related bug report:
https://code.google.com/p/android/issues/detail?id=58251
Despite what is mentioned in the bug report, my experience was the same with both ActionBarSherlock and ActionBarCompat. So I expect that ActionBarSherlock users are also affected.
Have you tried using collapseActionView()?
I use it like this:
public static MenuItem msearchMenuItem;
#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);
// 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()));
msearchMenuItem = menu.findItem(R.id.search);
return true;
}
public static MenuItem getSearchMenuItem() {
return msearchMenuItem;
}
public void doSomething(){
//Collapse the SearchBar
getSearchMenuItem().collapseActionView();
}
I don't know if it works with v7, but it certainly works with v4.
Try changing android:showAsAction="collapseActionView|ifRoom"
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/search"
android:title="#string/search_title"
android:icon="#drawable/ic_search"
android:showAsAction="collapseActionView|ifRoom"
android:actionViewClass="android.widget.SearchView" />
</menu>
Remove the line
searchView.setIconifiedByDefault(false);
Or you can explicitly call the method with true as the argument.
I use this code as this Android API Guides suggest to have a search widget in android 3.0 or more:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the options menu from XML
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.options_menu, 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()));
searchView.setIconifiedByDefault(false); // Do not iconify the widget; expand it by default
return true;
}
I have declared search menu item (and other menu item) in res/menu/menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/help"
android:icon="#android:drawable/ic_menu_help"
android:title="Help"
/>
<item android:id="#+id/menu_search"
android:icon="#android:drawable/ic_menu_search"
android:title="Search"
android:showAsAction="ifRoom"
/>
</menu>
I also created an activity for search results and its res/xml/searchable.xml settings, as API Guides suggest.
But as I start my app i get a NullPointerException atonCreateOptionsMenuand at onCreatePanelMenu
As #A--C said, You forgot that your menu_search item needs android:actionViewClass="android.widget.SearchView
Try adding that and see if it works. If not, make sure to attach your LogCat stack trace as an edit to your question.
