}

@Override

    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu, menu);
    return true;
}


@Override
public boolean onOptionsItemSelected(MenuItem item) {
     {
        if( R.id.icon==item.getItemId())     Toast.makeText(this, "You pressed the     icon!", Toast.LENGTH_LONG).show();

       if( R.id.icon==item.getItemId())      Toast.makeText(this, "You pressed the     text!", Toast.LENGTH_LONG).show();

       if( R.id.icon==item.getItemId())  Toast.makeText(this, "You pressed the      icon and text!", Toast.LENGTH_LONG).show();

    }
    return true;
}



}

at first sight i dont see anything wrong with that code. Have you tested it? does it work? does it throw an error? — Th0rndike, Mar 08 '12 at 12:04
the getItemId will return you the id what you wrote in menu.xml — viplezer, Mar 08 '12 at 12:05

try with this...

public boolean onOptionsItemSelected(MenuItem item)
    {
        System.out.println("entered to option selected");
        switch(item.getItemId())
        {

        case  R.id.icon:
            System.out.println("entered to icon");
            Toast.makeText(this, "icon clicked", Toast.LENGTH_LONG).show();
            break;

        case R.id.text:
            Toast.makeText(this, "text clicked", Toast.LENGTH_LONG).show();
            break;
        case R.id.iconandtext:
            Toast.makeText(this, "icon and text clicked", Toast.LENGTH_LONG).show();
            break;

        }

Use code like below:

 @Override
        public boolean onCreateOptionsMenu(Menu menu)
        {
         menu.add("Item1");
         menu.add("Item2");
         return true;
        }

You can use the following code inside the menu.xml

<?xml version="1.0" encoding="utf-8"?>
<menu
  xmlns:android="http://schemas.android.com/apk/res/android">
  <item
  android:id="@+id/menu1"
  android:alphabeticShortcut="s"
  android:title="menu1 title"
  />
  <item
  android:id="@+id/menu2"
  android:alphabeticShortcut="t"
  android:title="menu2 title"
  />
 </menu>

now the two methods for the invoking the menu and function which is to be called on the item selected.

@override
public boolean onCreateOptionsMenu (Menu menu){
    super.onCreateOptionsMenu(menu);
     //menu.add(R.menu.main_menu);
    //menu.add(Menu.NONE, 101,Menu.FIRST,this.getResources().getString(R.string.Title));
     MenuInflater mi = getMenuInflater();
     mi.inflate(R.menu.main_menu, menu);
     return true;
}

you can use the both the method of invoking the menu. First one by the menu.add and second one by the inflating the menu.xml file Now on the itemselectedlistner is used by the following code

public boolean onOptionsItemSelected(MenuItem item){
    switch(item.getItemId()){
    case R.id.menu1:
        //  your code here
    case R.id.menu2:
        //   your code here
    }
    return false;
}

just pass the id in switch-case and do whatever you want by selecting the those menu.
