Question

我无法为以下问题找到任何合适的解决方案。我有一些方法可以从手机返回联系人姓名和电话号码，它适用于很多设备。

但是，问题这个方法对我的htc（android 4.3.1）不起作用。我认为，可能主要原因是在游标声明的行上（Cursor phones = getContentResolver（）。query（ContactsContract.CommonDataKinds.Phone.CONTENT_URI，null，null，null，null）;），因为我通过getCount方法检查了Cursor对象，它显示零，这意味着它无法获取任何数据。我尝试了许多声明Cursor对象的方法，但我没有成功。

提前谢谢！请检查下面提到的代码：

private List<String> getContactNames() {
        List<String> contacts = new ArrayList<>();
        // Get the ContentResolver
        ContentResolver cr = getContentResolver();
        // Get the Cursor of all the contacts
        Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
        while (phones.moveToNext()) {
            String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
            String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
            phoneNumber = phoneNumber.replaceAll("[()+]", "");
            phoneNumber = phoneNumber.replaceAll(" ", "");
            if (phoneNumber.startsWith("8")) {
                phoneNumber = phoneNumber.replaceFirst("8", "7");
            }
            //contactNames.add(phoneNumber);
            contacts.add(name + "&&" + phoneNumber);
        }
        phones.close();
        Collections.sort(contacts, String.CASE_INSENSITIVE_ORDER);
        List<String> contactList =
                new ArrayList<>(new LinkedHashSet<String>(contacts));
        for (int i = 0; i < contactList.size(); i++) {
            String tem = contactList.get(i);
            String[] arr = tem.split("&&");
            contactNumbers.add(arr[1]);
            contactNames.add(arr[0]);
        }

        //Toast.makeText(this, contactNames.toString(), Toast.LENGTH_LONG).show();
        return contactList;
    }

使用此功能。

public class ContactsProvider {

private Uri QUERY_URI = ContactsContract.Contacts.CONTENT_URI;
private String CONTACT_ID = ContactsContract.Contacts._ID;
private String DISPLAY_NAME = ContactsContract.Contacts.DISPLAY_NAME;
private Uri EMAIL_CONTENT_URI = ContactsContract.CommonDataKinds.Email.CONTENT_URI;
private String EMAIL_CONTACT_ID = ContactsContract.CommonDataKinds.Email.CONTACT_ID;
private String EMAIL_DATA = ContactsContract.CommonDataKinds.Email.DATA;
private String HAS_PHONE_NUMBER = ContactsContract.Contacts.HAS_PHONE_NUMBER;
private String PHONE_NUMBER = ContactsContract.CommonDataKinds.Phone.NUMBER;
private Uri PHONE_CONTENT_URI = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
private String PHONE_CONTACT_ID = ContactsContract.CommonDataKinds.Phone.CONTACT_ID;
private String STARRED_CONTACT = ContactsContract.Contacts.STARRED;
private ContentResolver contentResolver;

public ContactsProvider() {
    contentResolver = GenericApplication.getContext().getContentResolver();
}

public List<Contact> getContacts() {
    List<Contact> contactList = new ArrayList<Contact>();
    String[] projection = new String[]{CONTACT_ID, DISPLAY_NAME, HAS_PHONE_NUMBER, STARRED_CONTACT};
    String selection = null;
    Cursor cursor = contentResolver.query(QUERY_URI, projection, selection, null, null);

    while (cursor.moveToNext()) {
        Contact contact = getContact(cursor);
        contactList.add(contact);
    }

    cursor.close();
    return contactList;
}

private Contact getContact(Cursor cursor) {
    String contactId = cursor.getString(cursor.getColumnIndex(CONTACT_ID));
    String name = (cursor.getString(cursor.getColumnIndex(DISPLAY_NAME)));
    Uri uri = Uri.withAppendedPath(QUERY_URI, String.valueOf(contactId));

    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setData(uri);
    String intentUriString = intent.toUri(0);

    Contact contact = new Contact();
    contact.id = Integer.valueOf(contactId);
    contact.name = name;
    contact.uriString = intentUriString;

    getPhone(cursor, contactId, contact);
    getEmail(contactId, contact);
    return contact;
}

private void getEmail(String contactId, Contact contact) {
    Cursor emailCursor = contentResolver.query(EMAIL_CONTENT_URI, null, EMAIL_CONTACT_ID + " = ?", new String[]{contactId}, null);
    while (emailCursor.moveToNext()) {
        String email = emailCursor.getString(emailCursor.getColumnIndex(EMAIL_DATA));
        if (!TextUtils.isEmpty(email)) {

        }
    }
    emailCursor.close();
}

private void getPhone(Cursor cursor, String contactId, Contact contact) {
    int hasPhoneNumber = Integer.parseInt(cursor.getString(cursor.getColumnIndex(HAS_PHONE_NUMBER)));
    if (hasPhoneNumber > 0) {
        Cursor phoneCursor = contentResolver.query(PHONE_CONTENT_URI, null, PHONE_CONTACT_ID + " = ?", new String[]{contactId}, null);
        while (phoneCursor.moveToNext()) {

            contact.phone = phoneNumber;
        }
        phoneCursor.close();
    }
}

}

使用此方法：

    private void LoadContactsWithPhone() {
    TextView contactView = (TextView) getView().findViewById(R.id.txtContacts);
    contactView.setText("");

    Cursor cursor = getContactsWithPhone();

    while (cursor.moveToNext()) {

        String displayName = cursor.getString(cursor
                .getColumnIndex(ContactsContract.Data.DISPLAY_NAME));

        String phoneNo = cursor.getString(cursor
                .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

        contactView.append("Name: ");
        contactView.append(displayName);
        contactView.append("\n");

        contactView.append("Phone: ");
        contactView.append(phoneNo);
        contactView.append("\n\n");

    }

}
    private Cursor getContactsWithPhone() {
    Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
    String[] projection = new String[]{ContactsContract.Contacts._ID,
            ContactsContract.Contacts.DISPLAY_NAME,
            ContactsContract.CommonDataKinds.Phone.NUMBER
    };

    String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER + " = ?";

    String[] selectionArgs = new String[]{String.valueOf(1)};

    String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";

    return getActivity().getContentResolver().query(uri, projection, selection, selectionArgs, sortOrder);
}

请使用以下代码在所有设备上使用以下代码： -

  public ArrayList<Contact_Model> getContacts(){

    ArrayList<Contact_Model> contact_models = new ArrayList<>();
    //        ContentResolver cr = context.getActivity().getContentResolver();
            ContentProviderClient mCProviderClient = context.getActivity().getContentResolver().acquireContentProviderClient(ContactsContract.Contacts.CONTENT_URI);
            Cursor cur = mCProviderClient.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);

            if (cur.getCount() > 0) {
                while (cur.moveToNext()) {
                    Contact_Model contact_model = new Contact_Model();
                    String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
                    String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                    String firstname;
