Android has a couple menu types.  The “option” menu is one that is access by using the unit’s menu button.  Since it is built into the view, you only need to

The setup – some constants:

	final public int MENU_GROUP=0;
	final public int MENU_ADD=0;
	final public int MENU_EDIT=1;
	final public int MENU_DELETE=2;

The setup – build the list

@Override 
public boolean onCreateOptionsMenu(Menu menu) {
 	menu.add(MENU_GROUP, MENU_ADD, 0, "add");
    	menu.add(MENU_GROUP, MENU_EDIT, 0, "edit");
    	menu.add(MENU_GROUP, MENU_DELETE, 0, "delete");
    	return super.onCreateOptionsMenu(menu); 
}

The handler – respond to the options

@Override 
public boolean onOptionsItemSelected(MenuItem item) {	
    	switch(item.getItemId()) { 
    	case MENU_ADD:
    		Intent intent = new Intent(getBaseContext(), editActivity.class);
    		intent.putExtra("ID", 0);
    		startActivity(intent);
    		return true;
    	case MENU_EDIT: 
    		return true;
    	case MENU_DELETE: 
    		return true;
    	} 
    	return super.onOptionsItemSelected(item);
}

    Button b = (Button) findViewById(R.id.btnSave);
    b.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {            	
                // Perform action on click
            	finish(); // close this screen
            }
    });
