Android - Can't add item to top of navigation view menu

Question

According to the documentation, to add an item to a Menu programmatically you use this.

By doing Menu.add(Menu.NONE, Menu.NONE, 0, "item"); I should be able to add an item to the very top of the menu of my navigation view, but despite this, the newly created item would still be added to the bottom. What could be the problem here?

Answer 1

   @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        menu.add(Menu.NONE, Menu.NONE, 1000, "Item First");
        menu.add(Menu.NONE, Menu.NONE, 500, "Item Second");
        menu.add(Menu.NONE, Menu.NONE, 200, "Item Third");

        return true;
    }
// 200 is lowest 500 in middle  and finally 1000 so the order is like below 

Should work for you!

Note : If you use both xml and code like below

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        menu.add(Menu.NONE, Menu.NONE, 0, "1000"); //<---- It's 0
        menu.add(Menu.NONE, Menu.NONE, 500, "500");
        menu.add(Menu.NONE, Menu.NONE, 200, "200");
        return true;
    }

and 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">
    <item
        android:id="@+id/action_settings"
                                      // <----------not Given
        android:title="5000"
        app:showAsAction="never" />

    <item
        android:id="@+id/main_item"
        android:orderInCategory="100"
        android:title="200"/>

    <item
        android:id="@+id/teams_item"
        android:orderInCategory="800"
        android:title="800"/>
</menu>

and if you forget to add orderInCategory to an item like in the 5000 one Then those items go in top giving priority to xml (check the example)

Answer 2

You have to use android:orderInCategory to position the menu at the correct place. The higher the Integer the top the menu will appear. Provide this android:orderInCategory for all the items in your menu and as well when you are adding it.
