Android : Navigation Menu Item's Group Sequences

Issue

I created a navigation menu XML file for my project. nav_menu.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">

<group
    android:id="@+id/group_note"
    android:checkableBehavior="single">
    <item
        android:id="@+id/note"
        android:icon="@drawable/all_notes"
        android:iconTint="@color/black1"
        android:title="Notes"/>
</group>

<group
    android:id="@+id/group_days"
    android:checkableBehavior="single">
            <!-- all days will come here -->
</group>

<group
    android:id="@+id/group_setting"
    android:checkableBehavior="none">
    <item
        android:id="@+id/setting"
        android:icon="@drawable/setting"
        android:iconTint="@color/black1"
        android:title="Settings" >
    </item>
</group>

group_days item will dynamically. But the problem is, I except group_days after group_note. But it comes after group_setting! I don't know why.

Solution

I think problem is that all items that you added in XML have default order and that means next added items will go below already added items like you have in your scenario. Try to give an order to your items for example for Notes it will obviously be 0: android:orderInCategory="0" and for Settings try: android:orderInCategory="2" and then for each new added item set category to 1. For example:

menu.add(R.id.monday, Menu.NONE, 1, "Monday");
menu.add(R.id.tuesday, Menu.NONE, 1, "Tuesday");
//and so on
