I have created one NavigationView inside DrawerLayout using Android Design Support Library
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/drawer_layout" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true"> <!-- other views --> <android.support.design.widget.NavigationView android:id="@+id/navigation" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_gravity="start" app:menu="@menu/my_navigation_items" /> </android.support.v4.widget.DrawerLayout>
my_navigation_items.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"> <group android:checkableBehavior="single"> <item android:id="@+id/bookmarks_drawer" android:icon="@drawable/ic_drawer_bookmarks" android:title="@string/bookmarks" /> <item android:id="@+id/alerts_drawer" android:icon="@drawable/ic_drawer_alerts" android:title="@string/alerts" /> <item android:id="@+id/settings_drawer" android:icon="@drawable/ic_drawer_settings" android:title="@string/settings" /> </group> </menu>
Now, I want to set unread notification counter for each item of NavigationView
like below image:
how to set unread notification counter on item of NavigationView
?
If you want to change badge with number, you can be changed in NOTIFICATION SETTING on the notification panel or Settings > Notifications > App icon badges > Select Show with number.
To use a DrawerLayout, position your primary content view as the first child with width and height of match_parent and no layout_gravity> . Add drawers as child views after the main content view and set the layout_gravity appropriately. Drawers commonly use match_parent for height with a fixed width.
com.google.android.material.navigation.NavigationView. Represents a standard navigation menu for application. The menu contents can be populated by a menu resource file. NavigationView is typically placed inside a DrawerLayout .
Drawer Layout In Android: In Android, DrawerLayout acts as top level container for window content that allows for interactive “drawer” views to be pulled out from one or both vertical edges of the window.
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) { } } }

I found this easy to implement solution on this web site https://android.jlelse.eu/android-adding-badge-or-count-to-the-navigation-drawer-84c93af1f4d9 Follow the steps below
Step 1: Create an Android Studio project, instead of choosing empty activity select “Navigation Drawer Activity”.
Step 2: Adding “actionViewClass” attribute to the navigation drawer menu (i.e. menu/youractivityname_drawer.xml)
<menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto"> <group android:checkableBehavior="single"> <item android:id="@+id/nav_camera" android:icon="@drawable/ic_menu_camera" android:title="Import" /> <item android:id="@+id/nav_gallery" app:actionViewClass="android.widget.TextView" android:icon="@drawable/ic_menu_gallery" android:title="Gallery" /> <item android:id="@+id/nav_slideshow" app:actionViewClass="android.widget.TextView" android:icon="@drawable/ic_menu_slideshow" android:title="Slideshow" /> <item android:id="@+id/nav_manage" android:icon="@drawable/ic_menu_manage" android:title="Tools" /> </group>
Step 3 : Declare the Navigation Drawer menu item and initialize the item with the badge value. In your main Activity, declare the menu item of the Navigation Drawer as given below
//Create these objects above OnCreate()of your main activity TextView slideshow,gallery; //These lines should be added in the OnCreate() of your main activity NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view); navigationView.setNavigationItemSelectedListener(this); gallery=(TextView) MenuItemCompat.getActionView(navigationView.getMenu(). findItem(R.id.nav_gallery)); slideshow=(TextView) MenuItemCompat.getActionView(navigationView.getMenu(). findItem(R.id.nav_slideshow)); //This method will initialize the count value initializeCountDrawer();
Step 5: Initialize initializeCountDrawer() where ever it’s required. It can also be used to update the count or badge value in the navigation drawer menu item.
private void initializeCountDrawer(){ //Gravity property aligns the text gallery.setGravity(Gravity.CENTER_VERTICAL); gallery.setTypeface(null, Typeface.BOLD); gallery.setTextColor(getResources().getColor(R.color.colorAccent)); gallery.setText("99+"); slideshow.setGravity(Gravity.CENTER_VERTICAL); slideshow.setTypeface(null,Typeface.BOLD); slideshow.setTextColor(getResources().getColor(R.color.colorAccent)); //count is added slideshow.setText("7"); }
