Can't Switch case R.id.action_search Action Bar compact?

I'm Implementing Action Bar in my App. But I have problem in switch item action_search, it's like not work. This my menu XML

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://ift.tt/nIICcg" 
    xmlns:myapp="http://ift.tt/GEGVYd">

   <item
        android:id="@+id/action_search"
        android:title="@string/menuitem_search"
        android:icon="@drawable/ic_action_search"
        myapp:actionViewClass="android.support.v7.widget.SearchView"
        myapp:showAsAction="ifRoom" />


    <item
        android:id="@+id/action_settings"
        android:orderInCategory="100"
        myapp:showAsAction="never"
        android:title="@string/action_settings"/>


</menu>

and this my code

@Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // toggle nav drawer on selecting action bar app icon/title
        if (mDrawerToggle.onOptionsItemSelected(item)) {
            return true;
        }
        // Handle action bar actions click
        switch (item.getItemId()) {

        case R.id.action_search:
            Toast.makeText(this, "test search choice", Toast.LENGTH_LONG).show();
            return true;
        case R.id.action_settings:
            Toast.makeText(this, "test setting choice", Toast.LENGTH_LONG).show();
            return true;
        default:
            return super.onOptionsItemSelected(item);
        }
    }

code above, if I choice action_settings CAN toast test setting choice , but if I choice action_search CAN NOT toast test search choice . how to fix it ?
