Displaying the phone number of a contact in Android Contact Content Provider -
i trying write program display id, name , phone number of contact in android. far id , names of contact displayed number of contact doesn't. can me, below code program:
package com.example.oghenekaroedoh.provider; import android.app.listactivity; import android.content.cursorloader; import android.database.cursor; import android.net.uri; import android.os.bundle; import android.provider.contactscontract; import android.util.log; import android.widget.cursoradapter; import android.widget.simplecursoradapter; public class provider2activity extends listactivity { @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_provider); uri allcontacts = contactscontract.contacts.content_uri; //query string our contacts //uri allcontacts = uri.parse("content://contacts/people"); //declare our cursor cursor c; string[] projection = new string[] {contactscontract.contacts._id, contactscontract.contacts.display_name, contactscontract.contacts.has_phone_number}; //---detect android version //---projection, filtering, , sorting /* >>the second parameter of managedquery() method (third parameter cursorloader class) controls how many columns returned query; parameter known projection >>the third parameter of managedquery() method (fourth parameter cursorloader class) enable specify sql clause filter result of query >>the fourth parameter of managedquery() method (the fifth parameter cursorloader class) enables specify sql order clause sort result of query, either in ascending or descending order * */ if (android.os.build.version.sdk_int <11) { //---if device ids running on os before honeycomb //use managedquery() of activity class retrieve managed cursor c = managedquery(allcontacts, projection, null, null, null); } else { //---honeycomb , later use cursor loader class retrieve managed cursor--- cursorloader cursorloader = new cursorloader( this, allcontacts, projection, null, null , null); c = cursorloader.loadinbackground(); } //create columns contacts display name , column string[] columns = new string[] { contactscontract.contacts.display_name, contactscontract.contacts._id}; int[] views = new int[] {r.id.contactname, r.id.contactid}; simplecursoradapter adapter; //detect android version again..s if (android.os.build.version.sdk_int <11) { //---if before honeycomb--- //use simplecursoradapter class map cursor view (like textviews imageviews e.t.c) adapter = new simplecursoradapter( this, r.layout.activity_provider, c, columns, views); } else { //---honeycomb , later--- ////use simplecursoradapter class map cursor view (like textviews imageviews e.t.c) //with parameter known cursoradapter.flag_register_current_observer adapter = new simplecursoradapter( this, r.layout.activity_provider, c, columns, views, cursoradapter.flag_register_content_observer); } this.setlistadapter(adapter); printcontacts(c); } private void printcontacts(cursor c) { //---display contact id , name , phone number---- if (c.movetofirst()) { do{ //---get contact id , name string contactid = c.getstring(c.getcolumnindex( contactscontract.contacts._id)); string contactdisplayname = c.getstring(c.getcolumnindex( contactscontract.contacts.display_name)); log.v("content providers", contactid + ", " + contactdisplayname); //---get phone number--- int hasphone = c.getint(c.getcolumnindex( contactscontract.contacts.has_phone_number)); if (hasphone == 1) { cursor phonecursor = getcontentresolver().query( contactscontract.commondatakinds.phone.content_uri, null, contactscontract.commondatakinds.phone.contact_id + " = " + contactid, null, null); while (phonecursor.movetonext()) { log.v("content providers", phonecursor.getstring( phonecursor.getcolumnindex( contactscontract.commondatakinds.phone.number))); } phonecursor.close(); } } while (c.movetonext()); } } }
i got example working adding customadapter myclassadapter extends arrayadapter, , populating arraylist of contact objects.
