What follows is how I did it. The part that was not obvious from the
sample code was the need for show(). Note that you can skip the
setIcon() and it'll use a default one. And you can skip the
setPositiveButton(), but then the user needs to hit the back button to
clear the dialog. showAlert() was nice, but AlertDialog is much more
versatile.
public boolean onOptionsItemSelected(MenuItem item){
switch (item.getItemId()) {
case 0:
Dialog about = new AlertDialog.Builder(CIDRCalculator.this)
.setIcon(R.drawable.icon)
.setTitle(R.string.about_dialog_title)
.setPositiveButton(R.string.about_dialog_ok, null)
.setMessage("CIDR Calc\nCopyright 2008\nRandy McEoin")
.create();
about.show();
return true;
}
return false;
}
