 AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
     builder.setTitle("Contacts");
     builder.setMessage(your_arraylist.toString());
     builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    dialog.cancel();
                }
            });
     builder.show();
