Navigationview Menu Items with Counter on the Right

NavigationView menu items with counter on the right

Starting from version 23 of appcompat-v7 NavigationView supports action views, so it is quite easy to implement counter yourself.

1. Create counter layout, i.e. 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" />
   

2. Reference it in your drawer menu xml, i.e. menu/drawer.xml:

   <item
       ...
       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.

3. Find menu item and set counter:

   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.

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

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);
   }
   

How to put counter on NavigationView from Android Design Library?

In new NavigationDrawer they have not mention an about the counter you are lookig for. But you can avoid the older way to put counter.

Because Navigation can contain any child view so you can use it like this.

<android.support.design.widget.NavigationView
        android:id="@+id/navView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="start">

        <ListView
            android:entries="@array/test"
            android:id="@+id/lvData"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>

    </android.support.design.widget.NavigationView>

So just reference your listview and give the customize layout as you want.

I know it is Older way of listview. But it will reduce the code of NavigationDrawer. I hope it helps you.

Note : Never use app:menu and child view in NavigationView at the same time. Otherwise it will overlap each other.

Style not getting applied to NavigationView menu in NavigationDrawer

so i figured out the issue, i was applying style the wrong way in NavigationView. Here is what i changed

before

style="@style/NavigationDrawerStyle"

after

app:itemTextAppearance="@style/NavigationDrawerStyle"

Anchoring a PopupMenu to Navigationview menu items

So I figured you can just create an empty view inside the menu item as follows:
create a layout xml file including only the following:

<?xml version="1.0" encoding="utf-8"?>
<View
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    />

lets call it "view_empty".

Now the menu item should have that empty view layout included inside of it by adding the following line to its item: app:actionLayout="@layout/drawer_empty"
My item looks as follows:

<item
                android:id="@+id/menubutton_submenuButton"
                android:title="example menu item"
                app:actionLayout="@layout/view_empty"/>

Now then, all that's left is just using it:

//onNavigationItemSelected(MenuItem menuItem) {
        switch (menuItem.getItemId()) {
            case R.id.menubutton_submenuButton:
                MenuItem item = drawerMenu.findItem(R.id.menubutton_submenuButton);
                PopupMenu popupMenu = new PopupMenu(this, MenuItemCompat.getActionView(item));
                popupMenu.getMenuInflater().inflate(R.menu.sub_menu, popupMenu.getMenu());
                popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                    @Override
                    public boolean onMenuItemClick(MenuItem item) {
                        //handle the inflated menu's buttons here
                        return true;
                    }
                });
                popupMenu.show();
                break;

What'd happen now is that the PopupMenu would anchor itself to an invisible view inside the menuItem, thus making it look like the container menuItem is the anchor point.
