You can use the following query to retrieve all numbers for a certain contact:

您可以使用以下查询来检索特定联系人的所有号码:

/* the following line assumes that the contactCursor you described
 * has the People._ID column at index 0 in its projection. */
int contactId = contactCursor.getInt(0);

Cursor numberCursor = getContentResolver().query(Phones.CONTENT_URI,
  new String[] {Phones.NUMBER}, Phones.PERSON_ID + "=" + contactId, null, null);
while(cursor.moveToNext()) {
  String number = cursor.getString(0);
}
cursor.close();
