How to use SearchView in Toolbar Android

The code on which I am working, is using a

Toolbar
and inflating a
menu
.

Here is the code

private Toolbar mToolbar;
mToolbar.inflateMenu(R.menu.chat_screen_menu);
setupMenu ();
private void setupMenu ()
{
mMenu = mToolbar.getMenu();
if (mMenu != null)
{
if (mChatPager != null && mChatPager.getCurrentItem() > 0)
{
mMenu.setGroupVisible(R.id.menu_group_chats, true);
mMenu.setGroupVisible(R.id.menu_group_contacts, false);
}
else
{
mMenu.setGroupVisible(R.id.menu_group_chats, false);
mMenu.setGroupVisible(R.id.menu_group_contacts, true);
mMenu.setGroupVisible(R.id.menu_group_otr_verified,false);
mMenu.setGroupVisible(R.id.menu_group_otr_unverified,false);
mMenu.setGroupVisible(R.id.menu_group_otr_off,false);
}
}
mToolbar.setOnMenuItemClickListener(new OnMenuItemClickListener ()
{
..........
}
}


But now, they require a
Search
button in the
tool_bar
.
I managed to put it, I followed a guide here
When I try to write something to search, the toast I had put to test the
listener
never shown.
which indicates
listener
is not working

@Override
public boolean onCreateOptionsMenu(Menu menu) {

MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.chat_screen_menu, menu);

SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
mSearchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.action_menu_search));
final Toast toast = new Toast(mApp);

if (mSearchView != null )
{
mSearchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
mSearchView.setIconifiedByDefault(false);

SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener()
{
public boolean onQueryTextChange(String newText)
{
mSearchString = newText;
//doFilterAsync(mSearchString);
toast.makeText(getApplicationContext(), "Test1", Toast.LENGTH_LONG).show();
return true;
}

public boolean onQueryTextSubmit(String query)
{
mSearchString = query;
//doFilterAsync(mSearchString);
toast.makeText(getApplicationContext(), "Test2", Toast.LENGTH_LONG).show();

return true;
}
};

mSearchView.setOnQueryTextListener(queryTextListener);
}

return true;

}

Answer

you have to use Appcompat library for that. which is used like below:

dashboard.xml

<item
    android:id="@+id/action_search"
    android:icon="@android:drawable/ic_menu_search"
    app:showAsAction="always"
    app:actionViewClass="android.support.v7.widget.SearchView"
    android:title="Search"/>

Activity file:

public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater menuInflater = getMenuInflater();
    menuInflater.inflate(R.menu.dashboard, menu);

     MenuItem searchItem = menu.findItem(R.id.action_search);

    SearchManager searchManager = (SearchManager) MainActivity.this.getSystemService(Context.SEARCH_SERVICE);

    SearchView searchView = null;
    if (searchItem != null) {
        searchView = (SearchView) searchItem.getActionView();
    }
    if (searchView != null) {
        searchView.setSearchableInfo(searchManager.getSearchableInfo(MainActivity.this.getComponentName()));
    }
        return super.onCreateOptionsMenu(menu);
}

manifest file:

<meta-data 
      android:name="android.app.default_searchable" 
      android:value="com.apkgetter.SearchResultsActivity" /> 

        <activity
            android:name="com.apkgetter.SearchResultsActivity"
            android:label="@string/app_name"
            android:launchMode="singleTop" >
            <intent-filter>
                <action android:name="android.intent.action.SEARCH" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.VIEW" />
            </intent-filter>

            <meta-data
                android:name="android.app.searchable"
                android:resource="@xml/searchable" />
        </activity>

searchable xml file:

<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:hint="@string/search_hint"
    android:label="@string/app_name" />

And at last, your SearchResultsActivity class code. for showing result of your search.
