android获取所有联系人

Question

如何获取Android中所有联系人的姓名并将其放入字符串数组中？

Answer 1

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();
    }
}

在不到一秒的时间内获取所有联系人，并且不会给您的活动带来任何负担。跟随我的脚步就像一个魅力。

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();
        }
    }
}

联系方式

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

public class MyActivity extends Activity 
                        implements LoaderManager.LoaderCallbacks<Cursor> {

    private static final int CONTACTS_LOADER_ID = 1;

        // or start a new one.

获取联系信息,照片联系人,照片uri并转换为班级模型

1).Class类型的示例:

    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;
    }

Answer 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
