How to add notification value for item on NavigationView for Material Design Drawer?

Question

My question is very simple, how to add a notification value right of the item on NavigationView for Material Design Drawer like that ?

Is there a property in the menu items for defining the drawer?

<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <group
        android:checkableBehavior="single">

        <item
            android:id="@+id/drawer_home"
            android:checked="true"
            android:icon="@drawable/ic_home_black_24dp"
            android:title="@string/home"/>

        <item
            android:id="@+id/drawer_favourite"
            android:icon="@drawable/ic_favorite_black_24dp"
            android:title="@string/favourite"/>
        ...

        <item
            android:id="@+id/drawer_settings"
            android:icon="@drawable/ic_settings_black_24dp"
            android:title="@string/settings"/>

    </group>
</menu>

Answer 1

This is possible with NavigationView from Version 23 of AppCompat-V7 using action views. 1. Create a layout for the counter e.g. nav_drawer_counter.xml:

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:gravity="center_vertical"
    android:textColor="@color/colorPrimary"/>

2. Add a reference to it from each item you'd like to show a counter value for in your menu/nav_drawer.xml (ensure you use the app namespace):

   <item 
       ...
       app:actionLayout="@layout/activity_main_nav_drawer_menu_counter"
       />
   

3. Add a method to set a value to the TextView e.g:

   @Override
   protected void onCreate(Bundle savedInstanceState) {
   ....
   setNavItemCount(R.id.nav_notifications, 10);
   }
   
   
   private void setNavItemCount(@IdRes int itemId, int count) {
   TextView view = (TextView) navigationView.getMenu().findItem(itemId).getActionView();
   view.setText(count > 0 ? String.valueOf(count) : null);
   }
   

Answer 2

Oh Yes... You can change that counter value.

From the images given by you it looks live you are using Rudson Lima's Material Design Navigation Drawer

In its library there is a function public void setNewCounterValue(int drawerItemPosition, int counterValue); inside the class NavigationLiveo.

Hope you will use its object properly to call this function.

Best of Luck... :-)
