如何修改Android代码以获取联系人姓名及标注为移动的电话号码？

Got it, let's adjust your code to exclusively pull mobile phone numbers while keeping all your existing valid contact logic (like filtering legal contacts and avoiding duplicate names) intact. Here's the modified code and a breakdown of the key changes:

Modified Full Code #

private ArrayList<ContactInfo> getLegalContacts() {
    ArrayList<ContactInfo> legalContacts = new ArrayList<>();
    List<String> contacts = loadLegalContacts();

    // Add selection to filter ONLY mobile phone numbers
    String selection = ContactsContract.CommonDataKinds.Phone.TYPE + " = ?";
    String[] selectionArgs = new String[]{String.valueOf(ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE)};

    Cursor phones = getContentResolver().query(
            ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
            null,
            selection,
            selectionArgs,
            ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC"
    );

    while (phones.moveToNext()) {
        String id = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
        String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
        String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

        // Keep your existing phone number formatting logic
        if (phoneNumber != null) {
            phoneNumber = phoneNumber.replace("(", "");
            phoneNumber = phoneNumber.replace(")", "");
            phoneNumber = phoneNumber.replace("-", "");
            phoneNumber = phoneNumber.replace(" ", "");
            phoneNumber = phoneNumber.replace("+", "");
        }

        // Only add if the contact is in your legal contacts list
        if (contacts.contains(id)) {
            ContactInfo info = new ContactInfo(id, name, phoneNumber, true);
            boolean isNew = true;
            for (int i = 0; i < legalContacts.size(); i++) {
                if (TextUtils.equals(legalContacts.get(i).name, name)) {
                    isNew = false;
                    break;
                }
            }
            if (isNew) {
                legalContacts.add(info);
            }
        }
    }
    phones.close();
    return legalContacts;
}

private List<String> loadLegalContacts() {
    List<String> contacts = new ArrayList<>();
    Set<String> set = SharedPrefUtil.getInstance().getStringSet("LegalContacts");
    if (set != null) {
        contacts.addAll(set);
    }
    return contacts;
}

Key Changes Explained #

• Filter Mobile Numbers at Query Time: We added a selection parameter to the query() call to only fetch records where the phone number type is TYPE_MOBILE. This is more efficient than fetching all numbers and filtering later, as it reduces the amount of data we process from the cursor.
• Preserved Existing Logic: All your original code for formatting phone numbers, checking against the legal contacts list, and avoiding duplicate names remains untouched—so your existing functionality works exactly as before, just with mobile-only numbers.

Optional: Include Other Mobile Types #

If you need to include additional mobile-related number types (like work mobile phones), update the selection logic to use an IN clause:

String selection = ContactsContract.CommonDataKinds.Phone.TYPE + " IN (?, ?)";
String[] selectionArgs = new String[]{
        String.valueOf(ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE),
        String.valueOf(ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE_WORK)
};
