如何通过单个查询从 ContentResolver 获取电话号码？

Question

我正在使用下面的代码获取联系人姓名和 ID，但我没有得到电话号码。如何从下面的代码中获取电话号码？

ContentResolver contentResolver = getBaseContext().getContentResolver();

Uri uri = ContactsContract.Contacts.CONTENT_URI;
String[] projection = {
        ContactsContract.Contacts._ID,
        ContactsContract.Contacts.DISPLAY_NAME,
        ContactsContract.Contacts.HAS_PHONE_NUMBER,
        ContactsContract.Contacts.STARRED,
        ContactsContract.Contacts.TIMES_CONTACTED,
        ContactsContract.Contacts.LAST_TIME_CONTACTED
};
String selection = String.format("%s > 0", ContactsContract.Contacts.HAS_PHONE_NUMBER);
String[] selectionArgs = null;
String sortOrder = String.format(
        "%s DESC, %s DESC, %S DESC, UPPER(%s) ASC",
        ContactsContract.Contacts.STARRED,
        ContactsContract.Contacts.TIMES_CONTACTED,
        ContactsContract.Contacts.LAST_TIME_CONTACTED,
        ContactsContract.Contacts.DISPLAY_NAME
);
Cursor cursor = contentResolver.query(uri, projection, selection, selectionArgs, sortOrder);

if (cursor.getCount() > 0) {
    while (cursor.moveToNext()) {
        String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
        String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));


        if (Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {

            System.out.println("name : " + name + ", ID : ");

         }

        }
    }
    cursor.close();
}

CModel.java

public class CModel {
String firstname;
String lastname;
String contactno;
String Imagepath;
int ID;
String contactid;

public String getCheck() {
    return Check;
}

String Check;

public String getContactid() {
    return contactid;
}

 public CModel(String fnm, String lastname, String userprofile, int ID,    String contactno, String Check) {
    this.firstname = fnm;
    this.lastname = lastname;
    this.Imagepath = userprofile;
    this.ID = ID;
    this.contactno = contactno;
    this.Check = Check;
}


public String getFirstname() {
    return firstname;
}

public String getLastname() {
    return lastname;
}

public String getContactno() {
    return contactno;
}

public String getImagepath() {
    return Imagepath;
}

public int getID() {
    return ID;
}

在你的活动文件中调用这个方法

private ArrayList<CModel> getcontact() {
ArrayList<CModel> contactlist = new ArrayList<CModel>;
try {
    Bitmap my_btmp = null;
    String profilepic;
    String phone = null;
    contactlist = new ArrayList<CModel>();
    ContentResolver cr = getContentResolver();
    String[] projection = new String[]{ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME};
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, projection, null, null,
            ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC");
    while (cur.moveToNext()) {
        String contactId = cur.getString(cur.getColumnIndex(ContactsContract.Data._ID));
        String displayName = cur.getString(cur.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
        Uri my_contact_Uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_URI, String.valueOf(contactId));
        InputStream photo_stream = ContactsContract.Contacts.openContactPhotoInputStream(getContentResolver(), my_contact_Uri);
        Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
                new String[]{contactId}, null);
        while (pCur.moveToNext()) {
            phone = pCur.getString(
                    pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
        }
        pCur.close();
        if (photo_stream != null) {
            BufferedInputStream buf = new BufferedInputStream(photo_stream);
            my_btmp = BitmapFactory.decodeStream(buf);
            profilepic = BitMapToString(my_btmp);
        } else {
            Bitmap bitmap = BitmapFactory.decodeResource(HomePage.this.getResources(), R.drawable.profilepic);
            my_btmp = bitmap;
            profilepic = BitMapToString(my_btmp);

        }
        String columns[] = {
                ContactsContract.CommonDataKinds.Event.START_DATE,
                ContactsContract.CommonDataKinds.Event.TYPE,
                ContactsContract.CommonDataKinds.Event.MIMETYPE,
        };
        String where =ContactsContract.CommonDataKinds.Event.MIMETYPE + " = '" + ContactsContract.CommonDataKinds.Event.CONTENT_ITEM_TYPE + "' and " + ContactsContract.Data.CONTACT_ID + " = " + contactId;
        String[] selectionArgs = null;
        String sortOrder = ContactsContract.Contacts.DISPLAY_NAME;
        Cursor birthdayCur = cr.query(ContactsContract.Data.CONTENT_URI, columns, where, selectionArgs, sortOrder);
        if (birthdayCur.getCount() > 0) {
            if (birthdayCur.moveToFirst()) {
                do {

                    contactlist.add(new CModel(displayName, "", profilepic, 0, phone,"phone"));
                    boolean flag = con.comparedata(phone);

                } while (birthdayCur.moveToNext());

            }

        }
        birthdayCur.close();
    }
    cur.close();
} catch (Exception e) {
}
return contactlist;

}

Answer 2

“ContactsContract.Contacts”中没有电话号码，但“ContactsContract.Contacts._ID”和“ContactsContract.CommonDataKinds.Phone.CONTACT_ID”对于每个联系人都是相同的。因此，您可以从 'ContactsContract.CommonDataKinds.Phone.CONTENT_URI' 获取电话号码。将此代码放在光标的循环中。总的来说，这是两个查询，但至少您知道在哪里搜索。这应该不会花费太多时间。

Cursor phoneCursor = managedQuery(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactId , null, null);

        while (phoneCursor.moveToNext()) {
           String phone = phoneCursor.getString(phoneCursor
                    .getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER));

        }

Answer 3

编辑：这是我在 1 个查询中检索每个电话号码的尝试，但我不确定是否存在任何没有电话号码的联系人；通常，最佳做法是始终查询具有电话号码的联系人列表，然后仅查询这些联系人号码。

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));

    //Do something with each name and phone somewhere each time you loop through; in your provided code you seemed to be printing them out

}
phones.close();

根据我之前写给联系人的一些工作，这篇较旧的帖子似乎很有帮助：How to get contacts' phone number in Android

一般情况下，电话号码存储为：

ContactsContract.CommonDataKinds.Phone.NUMBER 

所以对你提供的代码做一个 sn-p，我会大致这样编辑：

if (cursor.getCount() > 0) {
        while (cursor.moveToNext()) {
            String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
            String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
            String number = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));


            ...
            ...

        cursor.close();
    } 

当然，您需要确保在查询中从联系人中获取正确的数据段（即更新您的投影），但这应该有望为您指明正确的方向！
