在Github Repository 上添加了一个小库来获取联系人

【解决方案1】：

也试试这个，

private void getContactList() {
    ContentResolver cr = getContentResolver();
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
            null, null, null, null);

    if ((cur != null ? cur.getCount() : 0) > 0) {
        while (cur != null && cur.moveToNext()) {
            String id = cur.getString(
                    cur.getColumnIndex(ContactsContract.Contacts._ID));
            String name = cur.getString(cur.getColumnIndex(
                    ContactsContract.Contacts.DISPLAY_NAME));

            if (cur.getInt(cur.getColumnIndex(
                    ContactsContract.Contacts.HAS_PHONE_NUMBER)) > 0) {
                Cursor pCur = cr.query(
                        ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                        null,
                        ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
                        new String[]{id}, null);
                while (pCur.moveToNext()) {
                    String phoneNo = pCur.getString(pCur.getColumnIndex(
                            ContactsContract.CommonDataKinds.Phone.NUMBER));
                    Log.i(TAG, "Name: " + name);
                    Log.i(TAG, "Phone Number: " + phoneNo);
                }
                pCur.close();
            }
        }
    }
    if(cur!=null){
        cur.close();
    }
}

【讨论】：

由于某种原因，此代码将每个联系人获取两次。你知道为什么吗？
@Aerrow 有时会得到一些联系人两次。你解决了这个问题吗？
不要忘记关闭光标！
请勿使用此代码。它查询所有联系人，然后对每个联系人执行附加查询。糟糕的性能 - 在真实设备上运行可能需要 10 多秒。
@Vasiliy 是对的，如果您的联系人较少，您可能会被欺骗它很快，但对于拥有大量联系人的实际用户来说是个问题。

【解决方案2】：

获取联系人信息、照片联系人、照片 uri 并转换为 Class 模型

1)。类模型示例：

    public class ContactModel {
        public String id;
        public String name;
        public String mobileNumber;
        public Bitmap photo;
        public Uri photoURI;
    }

2)。获取联系人并转换为模型

     public List<ContactModel> getContacts(Context ctx) {
        List<ContactModel> list = new ArrayList<>();
        ContentResolver contentResolver = ctx.getContentResolver();
        Cursor cursor = contentResolver.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
        if (cursor.getCount() > 0) {
            while (cursor.moveToNext()) {
                String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
                if (cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)) > 0) {
                    Cursor cursorInfo = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                            ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[]{id}, null);
                    InputStream inputStream = ContactsContract.Contacts.openContactPhotoInputStream(ctx.getContentResolver(),
                            ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, new Long(id)));

                    Uri person = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, new Long(id));
                    Uri pURI = Uri.withAppendedPath(person, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);

                    Bitmap photo = null;
                    if (inputStream != null) {
                        photo = BitmapFactory.decodeStream(inputStream);
                    }
                    while (cursorInfo.moveToNext()) {
                        ContactModel info = new ContactModel();
                        info.id = id;
                        info.name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                        info.mobileNumber = cursorInfo.getString(cursorInfo.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                        info.photo = photo;
                        info.photoURI= pURI;
                        list.add(info);
                    }

                    cursorInfo.close();
                }
            }
            cursor.close();
        }
        return list;
    }

很棒的功能，只需要在完成第一个while子句后再添加一行来关闭光标。非常感谢
存储所有位图可能是个坏主意，例如您加载 1000 个位图，而用户只能看到前 10 个。

【讨论】：

很好地使用 CursorLoader。你知道如何从 CursorLoader 中的每个联系人中提取电话号码吗？
您可以实现 LoaderManager.LoaderCallbacks 而不是 LoaderManager.LoaderCallbacks。其中“联系人”是您的自定义实体。
@Artyom 你能解释一下如何获取电话号码部分吗？

【解决方案4】：

在不到一秒钟的时间内获取所有联系人，并且不会对您的活动造成任何负担。跟随我的步骤就像魅力一样。

ArrayList<Contact> contactList = new ArrayList<>();

private static final String[] PROJECTION = new String[]{
        ContactsContract.CommonDataKinds.Phone.CONTACT_ID,
        ContactsContract.Contacts.DISPLAY_NAME,
        ContactsContract.CommonDataKinds.Phone.NUMBER
};

private void getContactList() {
    ContentResolver cr = getContentResolver();

    Cursor cursor = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, PROJECTION, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");
    if (cursor != null) {
        HashSet<String> mobileNoSet = new HashSet<String>();
        try {
            final int nameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
            final int numberIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);

            String name, number;
            while (cursor.moveToNext()) {
                name = cursor.getString(nameIndex);
                number = cursor.getString(numberIndex);
                number = number.replace(" ", "");
                if (!mobileNoSet.contains(number)) {
                    contactList.add(new Contact(name, number));
                    mobileNoSet.add(number);
                    Log.d("hvy", "onCreaterrView  Phone Number: name = " + name
                            + " No = " + number);
                }
            }
        } finally {
            cursor.close();
        }
    }
}

联系人


public class Contact {
public String name;
public String phoneNumber;

public Contact() {
}

public Contact(String name, String phoneNumber ) {
    this.name = name;
    this.phoneNumber = phoneNumber;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getPhoneNumber() {
    return phoneNumber;
}

public void setPhoneNumber(String phoneNumber) {
    this.phoneNumber = phoneNumber;
}

}

好处

不到一秒
无负载
升序
没有重复的联系人

【讨论】：

这应该是被接受的答案。因为它太快了。谢谢
这非常好。需要提到的一个关键点是，这里的最大区别在于，此优化解决方案使用的 uri 是 ContactsContract.CommonDataKinds.Phone.CONTENT_URI，这使您可以直接访问 ContactsContract.CommonDataKinds.Phone.NUMBER 列。在更糟糕的答案中，您查询 uri ContactsContract.Contacts.CONTENT_URI，它不会让您访问 ContactsContract.CommonDataKinds.Phone.NUMBER 列，因此您必须使用每个联系人的 id 运行另一个查询才能访问它。

【解决方案5】：

改进@Adiii 的答案 - 它将清理电话号码并删除所有重复项

声明一个全局变量

// Hash Maps
Map<String, String> namePhoneMap = new HashMap<String, String>();

然后使用下面的函数

private void getPhoneNumbers() {

        Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);

        // Loop Through All The Numbers
        while (phones.moveToNext()) {

            String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
            String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

            // Cleanup the phone number
            phoneNumber = phoneNumber.replaceAll("[()\\s-]+", "");

            // Enter Into Hash Map
            namePhoneMap.put(phoneNumber, name);

        }

        // Get The Contents of Hash Map in Log
        for (Map.Entry<String, String> entry : namePhoneMap.entrySet()) {
            String key = entry.getKey();
            Log.d(TAG, "Phone :" + key);
            String value = entry.getValue();
            Log.d(TAG, "Name :" + value);
        }

        phones.close();

    }

请记住，在上面的示例中，键是电话号码，值是名称，因此请阅读您的内容，例如 998xxxxx282->Mahatma Gandhi 而不是 Mahatma Gandhi->998xxxxx282

【解决方案6】：

Cursor contacts = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
String aNameFromContacts[] = new String[contacts.getCount()];  
String aNumberFromContacts[] = new String[contacts.getCount()];  
int i = 0;

int nameFieldColumnIndex = contacts.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
int numberFieldColumnIndex = contacts.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);

while(contacts.moveToNext()) {

    String contactName = contacts.getString(nameFieldColumnIndex);
    aNameFromContacts[i] =    contactName ; 

    String number = contacts.getString(numberFieldColumnIndex);
    aNumberFromContacts[i] =    number ;
i++;
}

contacts.close();

结果将是一个包含联系人的NameFromContacts 数组。还要确保你已经添加了

<uses-permission android:name="android.permission.READ_CONTACTS" />

在 main.xml 中

【讨论】：

非常感谢，我会试试的，如果我有其他问题，我会问你
感谢帮助，如何在 ListView 中显示所有姓名？（我可以在另一个窗口中看到我手机中的所有联系人姓名）？谢谢
这个答案是错误的。 PhoneLookup.NUMBER 不是 ContactsContract.Contacts.CONTENT_URI 中的列，numberFieldColumnIndex 总是返回 -1。
应该是这样的：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)); } phones.close();

我正在使用这种方法，并且效果很好。它得到收藏、图片、姓名、号码等（联系人的所有详细信息）。而且它不是重复的。

列表

private static List<FavContact> contactList = new ArrayList<>();

获取联系人的方法

    ContentResolver contentResolver = context.getContentResolver();

            ,ContactsContract.Contacts.STARRED
    };
    String sort = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME_PRIMARY + " ASC";
    Cursor phones = contentResolver
            .query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI
                    , fieldListProjection, null, null, sort);
    HashSet<String> normalizedNumbersAlreadyFound = new HashSet<>();

    if (phones != null && phones.getCount() > 0) {
        while (phones.moveToNext()) {
            String normalizedNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));

            if (Integer.parseInt(phones.getString(phones.getColumnIndex(

                if (normalizedNumbersAlreadyFound.add(normalizedNumber)) {

                    int id = phones.getInt(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));
                    int fav = phones.getInt(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.STARRED));
                    boolean isFav;
                    isFav= fav == 1;

                    String uri = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI));
                    if(uri!=null){
                        contactList.add(new FavContact(id,isFav,uri,name,phoneNumber));
                    }
