Get only email address from contact list Android

Question

I want to display only those contact names whose email address is present. Otherwise that contact name should not be displayed in List. How can I do this? Can anybody please help me?

Answer 1

Here is my super fast query to pull email addresses. It is much faster than pulling all contact columns as suggested by other answers...

public ArrayList<String> getNameEmailDetails() {     ArrayList<String> emlRecs = new ArrayList<String>();     HashSet<String> emlRecsHS = new HashSet<String>();     Context context = getActivity();     ContentResolver cr = context.getContentResolver();     String[] PROJECTION = new String[] { ContactsContract.RawContacts._ID,              ContactsContract.Contacts.DISPLAY_NAME,             ContactsContract.Contacts.PHOTO_ID,             ContactsContract.CommonDataKinds.Email.DATA,              ContactsContract.CommonDataKinds.Photo.CONTACT_ID };     String order = "CASE WHEN "              + ContactsContract.Contacts.DISPLAY_NAME              + " NOT LIKE '%@%' THEN 1 ELSE 2 END, "              + ContactsContract.Contacts.DISPLAY_NAME              + ", "              + ContactsContract.CommonDataKinds.Email.DATA             + " COLLATE NOCASE";     String filter = ContactsContract.CommonDataKinds.Email.DATA + " NOT LIKE ''";     Cursor cur = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, PROJECTION, filter, null, order);     if (cur.moveToFirst()) {         do {             // names comes in hand sometimes             String name = cur.getString(1);             String emlAddr = cur.getString(3);              // keep unique only             if (emlRecsHS.add(emlAddr.toLowerCase())) {                 emlRecs.add(emlAddr);             }         } while (cur.moveToNext());     }      cur.close();     return emlRecs; } 

I tried the code provided by 'Agarwal Shankar' but it took about 4 seconds to get contacts on my test device, and this code took about 0.04 sec.

public ArrayList<String> getNameEmailDetails(){         ArrayList<String> names = new ArrayList<String>();         ContentResolver cr = getContentResolver();         Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);         if (cur.getCount() > 0) {             while (cur.moveToNext()) {                 String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));                 Cursor cur1 = cr.query(                          ContactsContract.CommonDataKinds.Email.CONTENT_URI, null,                         ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",                                  new String[]{id}, null);                  while (cur1.moveToNext()) {                      //to get the contact names                     String name=cur1.getString(cur1.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));                     Log.e("Name :", name);                     String email = cur1.getString(cur1.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));                     Log.e("Email", email);                     if(email!=null){                         names.add(name);                     }                 }                  cur1.close();             }         }         return names;     } 

the above method return an arraylist of names which has email id.
