For getting contact list from your phone book you need write permission in AndroidManifest.XML (i.e. android.permission.READ_CONTACTS) .And you can collect contact list using following method.

          ShowContact()
         {
           ArrayList<String> nameList;
           ArrayList<String> phoneNoList;

           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));
            String name = cur.getString(
                    cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
               if(Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
                   //Query phone here.  Covered next

                 Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?", 
                 new String[]{id}, null);
                  while (pCur.moveToNext()) {
                // Do something with phones
                    String phoneNo = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

                    nameList.add(name); // Here you can list of contact.
                    phoneNoList.add(phoneNo); // And here you can get list of phone number.You have to query separately for getting phone_no,email,name etc 
   // Here you have to iterate this(i.e. nameList) with your list in the database.And your rest of logic.

                } 
                pCur.close();                 
        }
     }      
   }
}

And Let me know if are having any issue in getting contact list.
