下面是论坛上有人写的关于获取Contact Number的code，非常详细，供参考。
String[] projection = new String[] { People._ID, People.NAME, People.NUMBER, }; // Get the base URI for People table in Contacts content provider. // which is: content://contacts/people/ Uri contactUri = People.CONTENT_URI; // Best way to retrieve a query; returns a managed query. Cursor peopleCursor = managedQuery (contactUri, projection, //Which columns to return. null, // WHERE clause--we won't specify. null, // Selection Args?? People.DEFAULT_SORT_ORDER); // Order-by name // go to the beginning of the list peopleCursor.moveToFirst(); // So, here we have a contact. We need to get the contact ID (_id) then // build the Uri to get the phones section of that user's record // which is a subdirectory of a contact record long personId = peopleCursor.getLong(peopleCursor.getColumnIndex("_id")); Uri personUri = ContentUris.withAppendedId(contactUri, personId ); // So now the URL looks like: content://contacts/people/_id(where the actual id of the record is here) Uri phoneUri= Uri.withAppendedPath(personUri, Contacts.People.Phones.CONTENT_DIRECTORY); // Now the URL looks like: content://contacts/people/_id/phones (where phones is literally "phones") // Now get all the phone numbers for this contact Cursor phonesCursor = managedQuery(phoneUri, null, null, null, Phones.DEFAULT_SORT_ORDER); // We now have a cursor for all the phone numbers for that User ID // go to the beginning of the phone list. phonesCursor.moveToFirst();
