Get only email address from contact list Android
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?
Solution 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.
Solution 2:
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.
