Use contentprovider to insert a contact

First, I declare that this example is an example from instructor Li Gang's crazy android handout. I just tried it again.

1. Declare the layout file first

<Linearlayout xmlns: Android = "http://schemas.android.com/apk/res/android" Android: layout_width = "fill_parent" Android: layout_height = "fill_parent" Android: Orientation = "vertical"> <edittext Android: id = "@ + ID/edittext1" Android: layout_width = "match_parent" Android: layout_height = "wrap_content" Android: EMS = "10" Android: hint = "Name: "> <requestfocus/> </edittext> <edittext Android: Id =" @ + ID/edittext2 "Android: layout_width =" match_parent "Android: layout_height =" wrap_content "Android: EMS = "10" Android: hint = "Tel:"/> <edittext Android: Id = "@ + ID/edittext3" Android: layout_width = "match_parent" Android: layout_height = "wrap_content" Android: EMS = "10" Android: hint = "Email:"/> <button Android: Id = "@ + ID/button1" Android: layout_width = "wrap_content" Android: layout_height = "wrap_content" Android: text = "insert contact"/> </linearlayout>

2. The main file is as follows:

Package COM. example. democontent; import android. app. activity; import android. content. contenturis; import android. content. contentvalues; import android.net. uri; import android. OS. bundle; import android. provider. contactscontract. commondatakinds. email; import android. provider. contactscontract. commondatakinds. phone; import android. provider. contactscontract. commondatakinds. structuredname; import android. provider. contactscontract. data; import android. provider. contactscontract. rawcontacts; import android. view. view; import android. view. view. onclicklistener; import android. widget. button; import android. widget. edittext; import android. widget. toast; public class mainactivity1 extends activity {private edittext et_name; private edittext et_phone; private edittext et_email; private button; @ overridepublic void oncreate (bundle savedinstancestate) {super. oncreate (savedinstancestate); setcontentview (R. layout. activity_main1); button = (button) findviewbyid (R. id. button1); et_name = (edittext) findviewbyid (R. id. edittext1); et_phone = (edittext) findviewbyid (R. id. edittext2); et_email = (edittext) findviewbyid (R. id. edittext3); button. setonclicklistener (New onclicklistener () {public void onclick (view arg0) {insert () ;}}) ;}public void insert () {string name = et_name.gettext (). tostring (); string email = et_email.gettext (). tostring (); string phone = et_phone.gettext (). tostring (); // create a contentvaluescontentvalues values = new contentvalues (); // send it to rawcontacturi. insert a null value in content_uri to obtain rawcontactiduri rawcontacturi = getcontentresolver (). insert (rawcontacts. content_uri, values); long rawcontactid = contenturis. parseid (rawcontacturi); values. clear (); values. put (data. raw_contact_id, rawcontactid); // sets the content type values. put (data. mimetype, structuredname. content_item_type); // set the contact name values. put (structuredname. given_name, name); // Add the contact name getcontentresolver () to the contact Uri (). insert (Android. provider. contactscontract. data. content_uri, values); values. clear (); values. put (data. raw_contact_id, rawcontactid); // sets the content type values. put (data. mimetype, phone. content_item_type); // set the contact's phone number values. put (phone. number, phone); // Add the phone number getcontentresolver () to the contact phone number Uri (). insert (Android. provider. contactscontract. data. content_uri, values); values. clear (); values. put (data. raw_contact_id, rawcontactid); // sets the content type values. put (data. mimetype, email. content_item_type); // sets the contact address values. put (email. data, email); // set the email type values. put (email. type, email. type_work); // Add the getcontentresolver () email to the contact (). insert (Android. provider. contactscontract. data. content_uri, values); toast. maketext (mainactivity1.this, "Contact added successfully", toast. length_short ). show ();}}

3. Permission issues

    <uses-permission android:name="android.permission.READ_CONTACTS" />    <uses-permission android:name="android.permission.WRITE_CONTACTS" />
