如何使用 ContentResolver 获取帐户类型？

Question

如何使用 ContentResolver 检索帐户类型（whatsapp、viber 等）？
这是我的代码

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

    if (cur.getCount() > 0) {
        while (cur.moveToNext()) {
            String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
            String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
            if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
                Log.d("log : ","name : " + name + ", ID : " + id);

                // get the phone number
                Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,
                        ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
                        new String[]{id}, null);
                while (pCur.moveToNext()) {
                    String phone = pCur.getString(
                            pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                    String phone1 = pCur.getString(
                            pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE));
                    Log.d("log : ","phone" + phone + " type : "+phone1);
                }
                pCur.close();

Answer 1

Android 的通讯录中的数据分为 3 个主要 table：

Contacts - 每个条目代表一个联系人，并将一个或多个 RawContacts
RawContacts - 每个条目代表有关联系人的数据，这些数据由某些 SyncAdapter（例如 Whatsapp、Google、Facebook、Viber）同步，这将多个数据条目分组
Data - 有关联系人、电子邮件、电话等的实际数据。每行是属于单个 RawContact

您的代码存在的问题是您遍历了所有 Contacts，然后查询每个联系人的电话号码。您查询的不是 RawContact table，其中包含您想要的 ACCOUNT_NAME 和 ACCOUNT_TYPE。另外，为了获取设备上的所有电话而进行数百次查询是非常低效的，您可以改为使用单个查询来完成。

// First create a mapping from RAW_CONTACT_ID to ACCOUNT_TYPE (e.g. Whatsapp)

Map<Long, String> rawContacts = new HashMap<Long, String>();
String[] projection1 = {RawContacts._ID, RawContacts.ACCOUNT_TYPE};
Cursor cur1 = cr.query(RawContacts.CONTENT_URI, projection1, null, null, null);
while (cur1 != null && cur1.moveToNext()) {
    Long id = cur1.getLong(0);
    String account = cur1.getString(1);
    rawContacts.put(id, account);
}

// Now query for all the PHONES on the device (no need to query the Contacts table at all)

String[] projection2 = { Phone.CONTACT_ID, Phone.DISPLAY_NAME, Phone.NUMBER, Phone.TYPE, Phone.RAW_CONTACT_ID };
Cursor cur2 = cr.query(Phone.CONTENT_URI, projection2, null, null, null);

while (cur2 != null && cur2.moveToNext()) {
    long id = cur2.getLong(0);
    String name = cur2.getString(1);
    String number = cur2.getString(2); // the actual info, e.g. +1-212-555-1234
    int type = cur2.getInt(3); // a numeric value representing type: e.g. home / office / personal
    long raw = cur2.getLong(4);

    Log.d(TAG, "contact: " + id + ", name: " + name + ", number: " + number + ", type: " + type + ", raw-id: " + raw + ", account-type: " + rawContacts.get(raw));
}

P.S. 您可以创建第二个 HashMap 并使用 CONTACT_ID 作为键，将每个联系人的有关单个联系人的所有信息分组。
