How to set shared checkable behavior across all groups in NavigationView?

Single Selection in Group NavigatioView Android

Here's the solution.

Step 1: Remove

android:checkableBehavior="single"
from both groups.

Step 2: Add the following logic to the listener:

mUiNavigationView.setNavigationItemSelectedListener(
            new NavigationView.OnNavigationItemSelectedListener() {
                @Override
                public boolean onNavigationItemSelected(MenuItem menuItem) {
                    menuItem.setCheckable(true);
                    menuItem.setChecked(true);
                    if (mPreviousMenuItem != null) {
                        mPreviousMenuItem.setChecked(false);
                    }
                    mPreviousMenuItem = menuItem;
                    //...
                    changeCurrentFragment(...);
                    return true;
                }
            });
Note: instead of calling menuItem.setCheckable(true) you can set android:checkable="true" for each item in XML.
