Hi, I did red

http://developer.android.com/guide/topics/ui/menus.html

http://developer.android.com/guide/topics/resources/menu-resource.html

I wrote this in main activity

  @Override   
  public boolean onCreateOptionsMenu(Menu menu) {
      MenuInflater inflater = getMenuInflater();
      inflater.inflate(R.menu.mainmenu, menu);
      return true;
  }
@Override
  public boolean onOptionsItemSelected(MenuItem item) {
      // Handle item selection
    switch (item.getItemId()) {
          case R.id.infos:
              infos();
            return true;
          case R.id.waring:
              waring();
            return true;
          case R.id.credits:
              credits();
            return true;
          case R.id.about:
              about();
            return true;
          default:
              return super.onOptionsItemSelected(item);
      }
}
  private void about() {
  //      // TODO Auto-generated method stub
//      // custom dialog
  
}

Where shoudd I put my alertbox (is this correct for a simple text box with no button ?) :

  new AlertDialog.Builder(this).setTitle("About").setMessage("el viva Android  !").create();

in private void about(), which never works

or directly in case R.id.about: about();

Quit lost here.

thks
