    <group android:checkableBehavior="single">
         . . .
         . . .
        <item
            android:id="@+id/nav_money"
            android:icon="@drawable/ic_nav_money"
            android:title="@string/title_nav_money" />
        <item
            android:id="@+id/nav_new_category"
            android:icon="@drawable/ic_nav_new_category" --> must add icon into drawable
            android:title="@string/title_nav_new_category" />
    </group> 
 </menu>

• <item

• android:id="@+id/nav_new_category"

• android:icon="@drawable/ic_nav_new_category"

• android:title="@string/title_nav_new_category" /> ----> item menu drawer

    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        ...
        ...
        <menu>
            <item
                android:id="@+id/nav_all"
                android:title="@string/title_nav_all"
                app:showAsAction="never" />
            <item
                android:id="@+id/nav_new_category"
                android:title="@string/title_nav_new_category"
                app:showAsAction="never"/>
            ...
            ...
         </menu>
    </item>
</menu>

• <item

• android:id="@+id/nav_new_category"

• android:title="@string/title_nav_new_category" /> ----> item menu drawer

5. Open file java/app/thecity/ActivityMain.java open method

public boolean onItemSelected(int id) {
	. . .
	switch (id) {
		. . .
		case R.id.nav_money:
			fragment = new FragmentCategory();
			bundle.putInt(FragmentCategory.TAG_CATEGORY, cat[9]);
			break;

		case R.id.nav_new_category:
			fragment = new FragmentCategory();
			bundle.putInt(FragmentCategory.TAG_CATEGORY, cat[10]);
			break;
		 default: 
			break; 
	 } 
 }

Handle when drawer menu click

• case R.id.nav_new_category:

• fragment = new FragmentCategory();

• bundle.putInt(FragmentCategory.TAG_CATEGORY, cat[10]);

• break;

nav_new_category --> menu id from menu_drawer.xml

cat [10] --> gain id new category from array of integer at category.xml

6. Open java/app/thecity/ActivityMaps.java

@Override
public boolean onOptionsItemSelected(MenuItem item) {
   . . . 
	} else {
		String category_text;
		if (item.getItemId() != R.id.menu_category) {
			category_text = item.getTitle().toString();
			switch (item.getItemId()) {
				case R.id.nav_all:
					cat_id = -1;
					break;

				case R.id.nav_new_category:
					cat_id = cat[10];
					break;
				 . . .

			}
			. . .

		}
	}
	return super.onOptionsItemSelected(item);
}
