programmatically set the selected property of a list item in Navigation Drawer

In my app I have two items in the Navigation Drawer which represent two modes:

1) All Countries Quiz
2) Favorite Quiz

When the user selects Favorite Quiz mode the application will check a particular condition. What I want is if the condition fails then I want to programatically set the selected property of the All Countries Quiz list item to checked. Basically it should revert to first mode if the condition of second mode fails.

Something like this:

1) User is currently on - All Countries Quiz Mode

enter image description here

2) Now user clicks on - Favorite Quiz Mode. If the condition is true then the everything goes normal and selector shift to second mode:

enter image description here

3) But if the condition fails, then the selection should not move to 2nd mode and should remain on 1st mode:

enter image description here

Here's the menu list code for the items on Navigation Drawer: 

<group android:checkableBehavior="single">
    <item
            android:id="@+id/nav_quiz_all"
            android:icon="@drawable/ic_public_black_24dp"
            android:checked="true"
            android:title="All Countries Quiz"/>
    <item
            android:id="@+id/nav_quiz_bookmarked"
            android:icon="@drawable/ic_favorite_black_24dp"
            android:title="Favorite Quiz"/>
</group>


<item android:title="Communicate">
    <menu>
        <item
            android:id="@+id/nav_rate"
            android:icon="@drawable/ic_star_black_24dp"
            android:title="Rate this app"/>
        <item
            android:id="@+id/nav_share"
            android:icon="@drawable/ic_share_black_24dp"
            android:title="Share"/>
        <item
            android:id="@+id/nav_feedback"
            android:icon="@drawable/ic_feedback_black_24dp"
            android:title="Feedback"/>
        <item
            android:id="@+id/nav_about"
            android:icon="@drawable/ic_info_black_24dp"
            android:title="About"/>
    </menu>
</item>


<item
    android:id="@+id/nav_settings"
    android:icon="@drawable/ic_settings_black_24dp"
    android:title="Settings"/>

you can use: setCheckedItem() method of NavigationView

snippet of code:

 @Override
public boolean onNavigationItemSelected(MenuItem item) {
  if(condition){
      mNavigationView.setCheckedItem(R.id.nav_item);  //yOur Item
    }
    mNavigationView.setCheckedItem(item.getItemId());

}

EDIT

you can use the following code snippet: call it in your activity when the condition applies..

mNavigationView.post(new Runnable() {
    @Override
    public void run() {
        navigationView.setCheckedItem(R.id.nav_item);
    }
});
