First build the layout file, the interface is very simple, is a search box and the following contact list:
Copy Code code as follows:

</LinearLayout>
Copy Code code as follows:

</LinearLayout>
</LinearLayout>
</LinearLayout>
Then the Click event: (Click to return the selected contact number to the input box)
Copy Code code as follows:
Get the Contact button object and bind the onclick click event
Phonebutton = (Button) Findviewbyid (R.id.find_phone);
Phonebutton.setonclicklistener (New Onclicklistener () {
public void OnClick (View v) {
Select the number from the contact, and then process the callback result by Onactivityresult () method
Intent Intent = new Intent (context, contactsactivity.class);
Startactivityforresult (Intent, Request_code);
}
});
/**
* Select the callback handler function for the contact person
*/

Case Request_code:
String phone = Data.getstringextra ("Phone");
Phoneedittext.settext (phone);
Break
}
}
}
The following is the activity of the Contact interface:
