Example to implement checkable items in OptionsMenu of Toolbar, modify from last example"Set image on Toolbar".

Modify menu/menu_main.xml, to add checkable items:

<?xml version="1.0" encoding="utf-8"?>
<menu 
 >
 <item
 android_id="@+id/item_checkable1"
 android_orderInCategory="100"
 android_title="Checkable opt 1"
 android_checkable="true"
 android_checked="true"/>
 <item
 android_id="@+id/item_checkable2"
 android_orderInCategory="100"
 android_title="Checkable opt 2"
 android_checkable="true"
 android_checked="false"/>
 <item
 android_id="@+id/item_normal"
 android_orderInCategory="100"
 android_title="Normal item"/>

</menu>

Modify MainActivity.java, modify onOptionsItemSelected() to handle the item click.

package com.blogspot.android_er.androidtoolbar;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar);
 setSupportActionBar(toolbar);

 getSupportActionBar().setTitle("Toolbar example");
 toolbar.setSubtitle("Android-er.blogspot.com");
 toolbar.setLogo(android.R.drawable.ic_menu_info_details);
 }

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
 getMenuInflater().inflate(R.menu.menu_main, menu);
 return super.onCreateOptionsMenu(menu);
 }

 @Override
 public boolean onOptionsItemSelected(MenuItem item) {

 Toast.makeText(this, item.getTitle(), Toast.LENGTH_LONG).show();

 int item_id = item.getItemId();
 switch(item_id){
 case R.id.item_checkable1:
 if(item.isChecked()){
 item.setChecked(false);
 }else{
 item.setChecked(true);
 }
 break;
 case R.id.item_checkable2:
 if(item.isChecked()){
 item.setChecked(false);
 }else{
 item.setChecked(true);
 }
 break;
 }

 return super.onOptionsItemSelected(item);
 }
}
