Answer 1

You could use the alert builder for this:

new AlertDialog.Builder(this)
    .setTitle("Delete entry")
    .setMessage("Are you sure you want to delete this entry?")
    .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
        public void onClick(/* don't remember the signature by heart... */) { 
            // continue with delete
        }
     })
    .setNegativeButton("No", new DialogInterface.OnClickListener() {
        public void onClick(/* don't remember the signature by heart... */) { 
            // do nothing
        }
     })
     .show();

Just be careful when you want to dismiss the dialog - use dialog.dismiss(). In my first attempt I used dismissDialog(0) (which I probably copied from some place) which sometimes works. Using the object the system supplies sounds like a safer choice. :)
