Step 1. Please add item in menu.xml

 <item
            android:id="@+id/navigation_drawer_item3"
            android:icon="@android:drawable/ic_menu_share"
            android:title=""
            app:actionLayout="@layout/spinner"/> 

Step 2. Please create layout for spinner view

<Spinner xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/spinner"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center_vertical"
    android:gravity="center_vertical" />

Step 3. set spinner data in your activity file

Spinner spinner = (Spinner) navigationView.getMenu().findItem(R.id.navigation_drawer_item3).getActionView();
    spinner.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_spinner_dropdown_item,language));
    spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {  
          Toast.makeText(MainActivity.this,language[position],Toast.LENGTH_SHORT).show();
        }
        @Override
        public void onNothingSelected(AdapterView<?> parent) {
        }
    });

Step 4. please add android support design library into project if need.
