How to add an id to the menu item programmatically in android

Question

I want to add a id name to get to change the fragments with onNavigationItemSelected, but I can not add an id programmatically. I need something like "setId ()" as in the code shown

menu.add("menu_name");
menu.getItem(i).setId("nav_item"+(i));
menu.getItem(i).setIcon(idIcon);

Answer 1

From Menu.java there is this signature of the add() method:

/**
 * Add a new item to the menu. This item displays the given title for its
 * label.
 * 
 * @param groupId The group identifier that this item should be part of.
 *        This can be used to define groups of items for batch state
 *        changes. Normally use {@link #NONE} if an item should not be in a
 *        group.
 * @param itemId Unique item ID. Use {@link #NONE} if you do not need a
 *        unique ID.
 * @param order The order for the item. Use {@link #NONE} if you do not care
 *        about the order. See {@link MenuItem#getOrder()}.
 * @param title The text to display for the item.
 * @return The newly added menu item.
 */

public MenuItem add(int groupId, int itemId, int order, CharSequence title);

Use it like this:

int newId = 100;
MenuItem newItem = menu.add(0, newId, 0, "New Item");

It returns the new menu item.
