formatting for the ListView items, as well as to collect the options ( string-

clicks.

public void onItemClick(AdapterView<?> arg0, View
arg1, int arg2, long arg3) {
if (arg2 == 0) {
startActivity(new Intent(Main.this, Game.class));
}
else if (arg2 == 1) {
Dialog d = new Dialog(this);
d.setContentView(R.layout.highscore);
d.setTitle("High Score");
d.show();
}
else if (arg2 == 2) {
Dialog d = new Dialog(this);
d.setContentView(R.layout.editplayer);
d.setTitle("Edit Player");
d.show();
}
}
Note The GAME MENU application consists of default responses
for handling most of the clicked items in the ListView . If you
