Problem
My code is as below: ``` String[] columns = {ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME, ContactsContract.Contacts.HAS_PHONE_NUMBER}; Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, columns, null, null, null); int ColumeIndex_ID = cursor.getColumnIndex(ContactsContract.Contacts._ID); int ColumeIndex_DISPLAY_NAME = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME); int ColumeIndex_HAS_PHONE_NUMBER = cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER); while(cursor.moveToNext()) { String id = cursor.getString(ColumeIndex_ID); String name = cursor.getString(ColumeIndex_DISPLAY_NAME); String has_phone = cursor.getString(ColumeIndex_HAS_PHONE_NUMBER); if(!has_phone.endsWith("0")) { System.out.println(name); GetPhoneNumber(id); } } cursor.close(); public String GetPhoneNumber(String id) { String number = ""; Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone._ID + " = " + id, null, null); if(phones.getCount() > 0) { while(phones.moveToNext()) { number = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); } System.out.println(number); } phones.close(); return number; } ``` I get contacts' name success, but get phone number fail in `GetPhoneNumber()`. The `phones.getCount()` always equal 0. How can I modify?
