Get contacts with email id

Question

I need to get contacts information(cursor) with email. They must be distinct. There must be one entry per contact if he has got an email. How to do it? I am targetting new c

Answer 1

just do it in simple way first of all find contact_id, on basis of it we will search all email_ids related for that contact. on any button click event write this code

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE);
startActivityForResult(intent, 2);

now on activity result,

protected void onActivityResult(int requestCode, int resultCode, Intent data) 
{
    System.out.println("Request Code--"+requestCode);
    super.onActivityResult(requestCode, resultCode, data);
    if (data != null && requestCode == 2) 
     {
            fromCurrent = true;
            Uri uri = data.getData();
            //fromCurrent=true;
            if (uri != null) {
                Cursor c = null;
                try {
                    c = getContentResolver().query(uri, new String[]{ 
                                ContactsContract.CommonDataKinds.Phone.CONTACT_ID,
                                ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
                                ContactsContract.CommonDataKinds.Email.DATA ,
                                ContactsContract.CommonDataKinds.Email.TYPE },
                            null, null, null);

                    if (c != null && c.moveToFirst()) {
                        String id = c.getString(0);
                        String name = c.getString(1);

                        System.out.println("id  "+id+" name:"+name);

                        ContactID = id;
                        retriveEmail();


                        if(arrEmail.size() == 0)
                        {
                            showToast("No Email Address found for the selected contact!");
                        }
                        else
                        {
                        ListFile = arrEmail.toArray(new String[arrEmail.size()]);

                          builder1 = new AlertDialog.Builder(ShareTheHeart_Activity.this);

                          builder1.setTitle("Select an email address :");

                          builder1.setSingleChoiceItems(ListFile,-1,new DialogInterface.OnClickListener() {     //@Override
                         public void onClick(DialogInterface dialog, int which) 
                         {
                            txtEmail.setText(ListFile[which]);
                            alert.cancel();
                          }
                         });

                          alert = builder1.create();
                          alert.show();      

                        }
                    }
                } finally {
                    if (c != null) {
                        c.close();
                    }
                }
            }
        }
}

where retriveEmail is created method, write it in your code this way,

  private void retriveEmail()
{
    try { 
        arrEmail = new ArrayList();
    String id = ContactID;

     // query for everything email  
   cursor = getContentResolver().query(Email.CONTENT_URI,  
            null, Email.CONTACT_ID + "=?", new String[] { id },  
            null);  

    int emailIdx = cursor.getColumnIndex(Email.DATA);  

    // let's just get the first email  
   if (cursor.moveToFirst())
   {
   do{  
        email = cursor.getString(emailIdx);  
        arrEmail.add(email);
        Log.v("ABC", "Got email: " + email);  
    } while(cursor.moveToNext());
    } else {  
        Log.w("ABC", "No results");  
    }  

} catch (Exception e) {  
    Log.e("ABC", "Failed to get email data", e);  
} finally {  
    if (cursor != null) {  
        cursor.close();  
    }   
    }
}

that's it.

please understand the code, don't just copy and paste!
