Here is step by step functionality:

add menu.xml

    <?xml version="1.0" encoding="utf-8"?>
    <menu xmlns:android="http://schemas.android.com/apk/res/android"
         xmlns:app="http://schemas.android.com/apk/res-auto">

         <item
              android:id="@+id/actionNotifications"
              android:icon="@drawable/ic_info_outline_white_24dp"
              android:menuCategory="secondary"
              android:orderInCategory="1"
              android:title="Cart"
              app:actionLayout="@layout/notification_layout"
              app:showAsAction="always" />
    </menu>

Then add notification_layout.xml, this layout will be used as the notification icons layout

     <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        style="@android:style/Widget.ActionButton"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_gravity="center"
        android:background="@android:color/transparent"
        android:clickable="true"
        android:gravity="center"
        android:orientation="vertical">

     <ImageView
         android:id="@+id/hotlist_bell"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:layout_margin="0dp"
         android:contentDescription="Notification Icon"
         android:gravity="center"
         android:src="@drawable/ic_info_outline_white_24dp" />

     <TextView xmlns:android="http://schemas.android.com/apk/res/android"
         android:id="@+id/txtCount"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:layout_marginBottom="@dimen/x5dp"
         android:layout_marginLeft="@dimen/x10dp"
         android:layout_marginRight="0dp"
         android:background="@drawable/pointer_"
         android:gravity="center"
         android:minWidth="17sp"
         android:text="0"
         android:textColor="#ffffffff"
         android:textSize="12sp" />
    </RelativeLayout>

now inside Activity

 @Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu, menu);

    final View notificaitons = menu.findItem(R.id.actionNotifications).getActionView();

    txtViewCount = (TextView) notificaitons.findViewById(R.id.txtCount);
    updateHotCount(count++);
    txtViewCount.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            updateHotCount(count++);
        }
    });
    notificaitons.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
    //    TODO
        }
    });


    return true;
}

You can put following function (taken from stackoverflow) inside the activity to update counter:

    public void updateHotCount(final int new_hot_number) {
    count = new_hot_number;
    if (count < 0) return;
    runOnUiThread(new Runnable() {
        @Override
        public void run() {
            if (count == 0)
                txtViewCount.setVisibility(View.GONE);
            else {
                txtViewCount.setVisibility(View.VISIBLE);
                txtViewCount.setText(Integer.toString(count));
                // supportInvalidateOptionsMenu();
            }
        }
    });
}

You only meant to say in your lower code: `if (count == 0) txtViewCount.setVisibility(View.GONE);` — Draško, Feb 19 '16 at 09:34
So, how can I align menu item to left of toolbar? (As image above) — Mucahit, Dec 01 '16 at 13:24

I think it is possible with :

<ImageView
        android:id="@+id/counterBackground"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/unread_background" /> <!-- your icon -->

    <TextView
        android:id="@+id/count"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="1"
        android:textSize="8sp"
        android:layout_centerInParent="true"
        android:textColor="#FFFFFF" />

And then using it for that icon as background.also, you need to remove/disable the default icon too.

You may want to take a look:

Remove the navigation drawer icon and use the app icon to open

Also, in the android-sdk/platforms/android-22/data/res, there should be that icon. You just need to find that and use it for your purpose (for example, adding that ImageView and adding it asbackground)

MaterialToolbar has ability to add BadgeDrawable:

For example in your Activity you can add the badge like this:

val toolbar: MaterialToolbar = findViewById(R.id.toolbar)
val badgeDrawable = BadgeDrawable.create(this).apply {
    isVisible = true
    backgroundColor = neededBadgeColor
    number = neededNumber
}
BadgeUtils.attachBadgeDrawable(badgeDrawable, toolbar, R.id.item_in_toolbar_menu)
