Updated answer:
Using app:actionLayout with support library 23.1.1 or higher will support the custom layout as below.
Create your custom counter layout like below.
menu_counter.xml:
<?xml version="1.0" encoding="utf-8"?>
<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:textAppearance="@style/TextAppearance.AppCompat.Body2" />
Reference it in your drawer menu item in xml.
menu/drawer.xml:
<item
android:id="@+id/navigation_drawer_item_1"
android:icon="@drawable/ic_menu_1"
android:title="@string/navigation_drawer_item_1"
app:actionLayout="@layout/menu_counter"
/>
Note that you should use app namespace, don't try to use android.
Alternatively you can manually set action view with MenuItem.setActionView() method.
Find menu item and set counter like below code:
private void setMenuCounter(@IdRes int itemId, int count) {
TextView view = (TextView) navigationView.getMenu().findItem(itemId).getActionView();
view.setText(count > 0 ? String.valueOf(count) : null);
}
Note, that you will need to use MenuItemCompat if you have to support Android 2.x versions.

Solved with ListView inside NavigationView as below code...
<android.support.design.widget.NavigationView
android:id="@+id/my_courses_nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="@layout/nav_header" >
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="150dp" > <!-- Give layout margin top according to "headerLayout" height -->
<ListView
android:id="@+id/left_drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/white"
android:cacheColorHint="@android:color/transparent"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp" />
</FrameLayout>
</android.support.design.widget.NavigationView>
In your activity set list item as below...
private final String[] mMenuTitles = { getResources().getString(R.string.bookmarks), getResources().getString(R.string.alerts), getResources().getString(R.string.settings) };
private final int[] mMenuIconId = { R.drawable.ic_drawer_bookmarks, R.drawable.ic_drawer_alerts, R.drawable.ic_drawer_settings };
ListView mDrawerList = (ListView) findViewById(R.id.left_drawer);
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
private ArrayList<SlideMenuItem> drawerItemList = new ArrayList<SlideMenuItem>();
for( int i = 0; i < mMenuTitles.length; i++ ) {
SlideMenuItem item = new SlideMenuItem();
item.setTitle(mMenuTitles[i]);
item.setIconID(mMenuIconId[i]);
// item..setUnread(5) //set or update unread count & notify dataset changed to adapter
drawerItemList.add(item);
}
MenuAdapter mMenuAdapter = new MenuAdapter( MyCoursesActivity.this, R.layout.drawer_list_item, drawerItemList);
mDrawerList.setAdapter(mMenuAdapter);
The click listener for ListView in the navigation drawer...
private class DrawerItemClickListener implements ListView.OnItemClickListener {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
try {
mDrawerLayout.closeDrawers();
SlideMenuItem item = (SlideMenuItem) parent.getItemAtPosition(position);
switch (item.getIconId()) {
case R.drawable.ic_drawer_bookmarks: {
}
break;
case R.drawable.ic_drawer_alerts: {
}
break;
case R.drawable.ic_drawer_settings: {
}
break;
default: {
}
break;
}
} catch (Exception e) {
}
}
}
