android -Menu function

Question

hi, I am new to android.I have tested the android.view.menu by the following code..It works.

import android.app.Activity; import android.os.Bundle; import android.view.Menu; public class menu extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } public boolean onCreateOptionsMenu(Menu menu) { menu.add(Menu.NONE, 1, Menu.NONE, "1 Pixel"); menu.add(Menu.NONE, 2, Menu.NONE, "2 Pixels"); menu.add(Menu.NONE, 3, Menu.NONE, "8 Pixels"); menu.add(Menu.NONE, 4, Menu.NONE, "16 Pixels"); menu.add(Menu.NONE, 5, Menu.NONE, "24 Pixels"); menu.add(Menu.NONE, 6, Menu.NONE, "32 Pixels"); menu.add(Menu.NONE, 7, Menu.NONE, "40 Pixels"); return(super.onCreateOptionsMenu(menu)); }

}

I just what to know how to add action to each menu.whether we can add intent to each menu buttons.if possible please help me out.Thanks in advance..

1. To create menu you need both of the methods without using xml:

   public boolean onCreateOptionsMenu(Menu menu) { super.onCreateOptionsMenu(menu); this.menu = menu;

       menu.add(0, 1, Menu.NONE, "Save");
   
   
   menu.add(0, 2, Menu.NONE, "Close"); 
   
   
   return true;
   
   
    }
   

   public boolean onOptionsItemSelected(MenuItem item) { super.onOptionsItemSelected(item);

       switch (item.getItemId()) {
   
   
   case 1:          
         break;
       case 2:       
         break;
   }
   
   
     return false;
   

   }
