Android - display specific contacts information

In my application when a user clicks on a button I want to open the contacts application and display a particular contacts information.

At the minute I have this:

Intent intent = new Intent(Intent.ACTION_VIEW, People.CONTENT_URI);
startActivity(intent);

This displays the contact application with all the contacts displayed.

But how do I get it to display just one contact according to the contacts 开发者_Python百科name or number?

This Code works: (answer)

Uri contactUri = ContentUris.withAppendedId(People.CONTENT_URI, 23);

Intent intent = new Intent(Intent.ACTION_VIEW, contactUri);
startActivity(intent);

Append the contact ID number to the end of the URI.

For instance content://contacts/people/615

or People.CONTENT_URI + "/" + contactId

The ID number will come from your original contact query.
