android - How to make a phone call (to call a given person) if we know the contact's _ID -

my problem store contacts/persons' _id in database , want initiate phone phone call in order phone call stored contact when user presses button.

i retrieve _id cursor , store database

string cont_id = cursor.getint(cursor.getcolumnindex(contactscontract.contacts._id)); ...

later on, when user presses button call

 intent intent = new intent(intent.action_dial, uri.parse("content://contacts/people/" + cont_id));  startactivity(intent);

now problem dialer displayed "empty", not display desired person.

so, seems not fill in person. android development guide says @ intent description:

action_dial content://contacts/people/1 -- display phone dialer person filled in.

how else should fill in desired person? hint?

uri.parse("content://contacts/people/" + cont_id)

here expecting content://contacts/people/ + cont_id should give phone number not happen bcoz need query content provider.

note: please refer link fetch contacts:
