我把我的代码放在下面.

Cursor c = cr.query(
                        ContactsContract.RawContacts.CONTENT_URI,
                        new String[] { ContactsContract.RawContacts.CONTACT_ID, ContactsContract.RawContacts.DISPLAY_NAME_PRIMARY },
                        ContactsContract.RawContacts.ACCOUNT_TYPE + "= ?",
                        new String[] { "com.whatsapp" },
                        null);

                ArrayList<String> myWhatsappContacts = new ArrayList<>();

                if(c != null) {
                    if (c.getCount() > 0) {
                        while (c.moveToNext()) {

                            String whatsappContactId = c.getString(c.getColumnIndex(ContactsContract.RawContacts.Data._ID));

                            Cursor dataCursor = cr.query(
                                    ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                                    projection,
                                    ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
                                    new String[]{whatsappContactId}, null);
                            // You can also read RawContacts.CONTACT_ID to read the

我从电话簿中获取了所有设备联系人.现在我想从电话簿中获取的特定联系人获取链接帐户(facebook,twitter,instagram,LinkedIn).我该怎么办？

这是获取联系人的代码.

public Cursor getContactsCursor(FragmentActivity activity) {
        Cursor cursor = null;
        try {
            String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + "= 0" + " OR " + ContactsContract.Contacts.IN_VISIBLE_GROUP + "= 1";
            String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
            ContentResolver cr = activity.getContentResolver();
            return cr.query(ContactsContract.Contacts.CONTENT_URI, null, selection, null, sortOrder);
        } catch (Exception e) {
            AppLogger.e(Helper.class.getSimpleName(), e.getMessage());
            return cursor;
        }
    }

现在我不知道如何获取与特定联系人链接的帐户(如facebook,linkedin等).

有人可以指导我.

更新: 在下面附加的图像中,单击红色突出显示的部分,在浏览器中打开链接的用户配置文件.因此,我愿意获取用于打开用户个人资料页面的字段.

提前致谢.

我是Android新手，并尝试执行以下任务：-我想打开Whatsapp联系人列表并获取选定的联系人数据。我能够完成一半的工作。Whatsapp联系人列表打开，但是一旦我按任何联系人，我的应用程序就会崩溃。这是我的代码：

要打开Whatsapp联系人列表：

btnChoose.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(Intent.ACTION_PICK);
            intent.setPackage("com.whatsapp");
            try{
                Toast.makeText(AddScheduleActivity.this, "going out activity", Toast.LENGTH_SHORT).show();
                startActivityForResult(intent, 1);
                Toast.makeText(AddScheduleActivity.this, "getting In activity", Toast.LENGTH_SHORT).show();
            } catch (Exception e) {
                Toast.makeText(AddScheduleActivity.this, "Whatsapp not found", Toast.LENGTH_SHORT).show();  //no activity found to handle this intent means whatsapp is not installed
            }
        }
    });

获得选择：-

@Override
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);
    Toast.makeText(AddScheduleActivity.this, "Ok In", Toast.LENGTH_SHORT).show();

    switch (requestCode) {
        case 1:
            if(resultCode == …
