如何将android联系人与firebase数据库同步

时间:2016-11-23 13:22:32

标签: android firebase-realtime-database android-syncadapter android-database

我是Android编程的新手,我正在开发一个应用程序,其中用户在firebase中有一个帐户,他想要将他/她的手机联系人与firebase数据库联系人同步。一种方法是获取所有firebase联系人并与用户手机联系人进行比较并过滤掉类似的联系人并更新视图.....但这个逻辑是荒谬的,当firebase数据库增加时,即达到百万用户!

请帮助我....或至少给我正确的方向,我应该开始工作!

我的数据库树

以下是我的数据库树如何看起来像我应该如何保存

为了尽可能通用,您可以创建一个带有所有国家/地区前缀的类。

public class CountryToPhonePrefix {
    public static String getPhone(String code) {
        return country2phone.get(code.toUpperCase());
    }
    public static Map<String, String> getAll(){
        return country2phone;
    }
    private static Map<String, String> country2phone = new HashMap<String, String>();
    static {

MainActivity中,您可以调用以下函数来获取设备中的联系人列表。

private void getContactList(){

    String ISOPrefix = getCountryISO();

    Cursor phones = getContext().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 phone = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

        phone = phone.replace(" ","");
        phone = phone.replace("-","");
        phone = phone.replace("(","");
        phone = phone.replace(")","");

        if (!String.valueOf(phone.charAt(0)).equals("+")) {
            phone = ISOPrefix + phone;
        }

        UserObject mContact = new UserObject("",name, phone);
        contactList.add(mContact);
        getUserDetails(mContact);
    }
}

在这里您可以从设备获取CountryISO。

private String getCountryISO(){
    String iso = null;

    TelephonyManager telephonyManager = (TelephonyManager) getContext().getSystemService(getContext().TELEPHONY_SERVICE);
    if (telephonyManager.getNetworkCountryIso() != null) {
        if (!telephonyManager.getNetworkCountryIso().toString().equals("")) {
            iso = telephonyManager.getNetworkCountryIso().toString();
        }
    }

    return CountryToPhonePrefix.getPhone(iso);
}

在这里,您可以根据联系人列表在Firebase Realtime数据库中搜索在您的应用程序中拥有帐户的人。

private void getUserDetails(UserObject mContact) {
    DatabaseReference mUserDB = FirebaseDatabase.getInstance().getReference().child("user");
    // Only lists the users that have an account in the app into Firebase
    Query query = mUserDB.orderByChild("phone").equalTo(mContact.getPhone());
    query.addListenerForSingleValueEvent(new ValueEventListener() {
        @Override
        public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
            if (dataSnapshot.exists()) {
                String uid, name = "", phone = "", email, image;

                for (DataSnapshot childSnapshot : dataSnapshot.getChildren()){
                    uid = childSnapshot.getKey().toString();
                    if (childSnapshot.child("phone").getValue() != null) {
                        phone = childSnapshot.child("phone").getValue().toString();
                    }
                    if (childSnapshot.child("name").getValue() != null) {
                        name = childSnapshot.child("name").getValue().toString();
                    }
                    email = childSnapshot.child("email").getValue().toString();
                    image = childSnapshot.child("image").getValue().toString();

                    UserObject mUser = new UserObject(childSnapshot.getKey(), name, phone);
                    mUser.setImageUrl(image);

                    if (name.equals(phone)) {
                        for (UserObject mContactIterator : contactList) {
                            if (mContactIterator.getPhone().equals(mUser.getPhone())) {
                                mUser.setName(mContactIterator.getName());
                            }
                        }
                    }


                    return;
                }
            }
        }

        @Override
        public void onCancelled(@NonNull DatabaseError databaseError) {

        }
    });
}

希望对您有帮助!

您需要首先从系统获取联系人列表,然后将其保存到数据库中。 决定,你在数据库中存储联系人信息的方式(可能是一些额外的信息),然后从数据库中调整示例项目(这样可以将单个消息保存为节点的子项)
