How to read contacts on Android 2.0 -

I am working on Android 2.0 and am trying to get a list of all the contacts.

android.provider.Contacts.People has been deleted, I have to use android.provider.ContactsContract , but I think it Can not find a proper example of how to use (for example: retrieve a list of all contacts on the Phonebook.)

Anyone know where such an example is ?

First of all, make sure you have added

  & amp; ; Usage-permission Android: name = "android.permission.READ_CONTACTS" />   
 In your AndroidManifest.xml file, you can loop through your phone contacts like this.  
  cursor cursor = getContentResolver () query (ContactsContract contact.contENT_URI, empty, empty, empty, empty); While (cursor.movetext ()) {string contactID = cursor.gate string (cursor.gate column index (contact contact ._id)); String isphone = cursor.get string (cursor.zstallmandindex (contactCact.CommunicationsHAS_PHONE_NUMBER)); If (Boolean.parseBoolean (hasPhone)) // // You know this is now a number so call this cursor like this query = getContentResolver (). Query (ContactsContract.CommonDataKinds.Phone.CONTENT_URI, Null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + Contact ID, empty, empty); While (phones.moveToNext ()) {string PhoneNumber = phones.getString (phones.getColumnIndex (ContactsContract.CommonDataKinds.Phone.NUMBER)); } Phones.close (); } Cursor email = getContentResolver () query (ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, ContactsContract.CommonDataKinds.Email.CONTACT_ID + "=" + contactId, null, null). While email (emails.moveToNext ()) {// This will allow you to receive multiple email addresses String EmailAddress = emailss.getString (emails.getColumnIndex (ContactsContract.CommonDataKinds.Email.DATA)); } Emails.close (); } Cursor.close ();   
 Additionally, you can loop through your contacts and just get the name and the phone number like this:  
  Cursor people = GetContentResolver () Query (ContactsContract contact.contENT_URI, empty, empty, empty, empty); Whereas (people.moveToNext ()) {int nameFieldColumnIndex = people.getColumnIndex (PhoneLookup.DISPLAY_NAME); String contact = people.getString (nameFieldColumnIndex); Int NumberFieldColmainIndex = People. Tolkoll Index (phone lookup number); String number = people Gatestring (number field code); } People Close ();   
 In addition, if you need to get things like a note from a contact, you will need to use the following URIs, such as the following (to use this method Free):  
  Private string millennium (long contact ID) {string note = zero; String [] column = new string [] {ContactsContract.CommonDataKinds.Note.NOTE}; Where the string is where = contact contact Data .RAW_CONTACT_ID + "=" and "Contact + Contacts. Data MIMETYPE + "=?"; String [] where parameter = new string [] {long. Tother (Contact ID), Contact Editing CommonDayind note. CONTENT_ITEM_TYPE}; Cursor contact = getContentResolver (). Query (ContactsContract.Data.CONTENT_URI, projection, ou, ou parameter, faucet); If (contacts.moveToFirst ()) {RV = contacts.getString (0); } Contacts.close (); Return note; }   
 Note this time that I have not only used the MIME type for query but also the query ID.
