<?xml version="1.0" encoding="utf-8"?>
<menu
xmlns:android="http://schemas.android.com/apk/res/android">
<item
    android:id="@+id/feeds"
    android:title="Feeds"/>
<item
    android:id="@+id/friends"

推荐答案

请参阅：==

private int group1Id = 1;

int homeId = Menu.FIRST;
int profileId = Menu.FIRST +1;
int searchId = Menu.FIRST +2;
int dealsId = Menu.FIRST +3;
int helpId = Menu.FIRST +4;
int contactusId = Menu.FIRST +5;

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    menu.add(group1Id, homeId, homeId, "").setIcon(R.drawable.home_menu);
    menu.add(group1Id, profileId, profileId, "").setIcon(R.drawable.profile_menu);
    menu.add(group1Id, searchId, searchId, "").setIcon(R.drawable.search_menu);
    menu.add(group1Id, dealsId, dealsId, "").setIcon(R.drawable.deals_menu);
    menu.add(group1Id, helpId, helpId, "").setIcon(R.drawable.help_menu);
    menu.add(group1Id, contactusId, contactusId, "").setIcon(R.drawable.contactus_menu);

    return super.onCreateOptionsMenu(menu); 
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case 1:
        // write your code here
        Toast msg = Toast.makeText(MainHomeScreen.this, "Menu 1", Toast.LENGTH_LONG);
        msg.show();
        return true;

    case 2:
        // write your code here
        return true;

    case 3:
        // write your code here
        return true;

    case 4:
        // write your code here
        return true;

    case 5:
        // write your code here
        return true;

    case 6:
        // write your code here
        return true;

    default:
        return super.onOptionsItemSelected(item);
    }
}
