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
